Introduction CT-479
http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapterpic1small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapterpic1.jpg)
We are going to take a look at the ASUS CT-479 Adapter which allows you to use an Intel Mobile Processor in your desktop. This Socket 478 to Socket 479 converter is considerably less expensive than the native Socket 479 boards, which you will not find for less than 200 US dollars at the time of this review.
With the ASUS CT-479 adapter you can turn that old ASUS 865P/875P mobo into a serious gaming machine. If you have one of the supported ASUS motherboards and the latest BIOS this may be one of the cheapest performance purchases you can make. What this review will focus on is the performance between the ASUS P4P800-E with a P4 3.2E Prescott and the ASUS CT-479 adapter with a Pentium M 750 Dothan.
It is possible to get higher clocks out of this board by doing the vdroop and vdimm voltage mods, however since most of our readers will just install the adapter and not do the mods, I decided not to do them for the review. Instead, as an extra bonus, I'm going to review the OCZ DDR Booster along with the ASUS CT-479 Adapter.

Introduction OCZ DDR Booster
http://www.techpowerup.com/reviews/ASUS/CT-479/images/booster_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/booster.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/bkbooster_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/bkbooster.jpg)
There's nothing like a one two punch, and since we are teaming the ASUS CT-479 with the OCZ DDR Booster they should be nothing less. Using OCZ PC4000 Dual Channel Gold (http://www.ocztechnology.com/products/memory/ocz_el_ddr_pc_4000_dual_channel_gold_rev_2) memory with the DDR Booster should allow us to run the memory at a higher voltage for tighter timings and with OCZ's EVP (Extended Voltage Protection) we can run these modules at 3.0V without voiding their Lifetime warranty, and not voiding the warranty on the motherboard with a VDIMM mod.
What is a DDR Booster you ask? Well the official name to start with is the DDR Booster Diagnostic Device. The device is designed to provide cleaner power to create a more stable memory environment. Plugged directly into the PSU, the booster allows you to adjust the VDIMM, in certain circumstances up to 3.9V. Equipped with an LED to show VDIMM readout the Booster operates in and takes up one memory slot, which may not sound appealing to some. If you've looked at the native Socket 479 motherboards none have more than two DDR1 memory sockets, thus another point for the ASUS solution.
Take note of the OCZ Booster compatibility below, these are only the boards that OCZ has tested in house, but that does not mean it will not work with other models. A quick email to OCZ support would clarify any concerns. Having dealt with their customer service personally, I can contest it's second to none.
Supported CT-479 motherboards listed on DDR Booster Compatibility List
P4P800-E
P4C800-E
Important notes for DDR Booster Compatibility
Use of the DDR Booster with certain chipsets/motherboards may limit maximum DIMM population.
VTT mod may be needed to reach above 3.0 VDIMM
Power supply quality may affect DDR Booster performance and stability.
DDR Booster power adapter may not fit all Levicom Power Supply models due to Levicom's use of a non-standard ATX adapter.
Power supplies used in conjunction with the DDR Booster must support a -5V line in order for the LED readout to function.
The OCZ Booster requires a 20-Pin ATX connector and will not work with power supplies that have 24-Pin connectors

Packaging ASUS CT-479
http://www.techpowerup.com/reviews/ASUS/CT-479/images/displayedsmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/displayed.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/contentssmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/contents.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/boxsmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/box.jpg)
The packaging is pretty laid back with ASUS promoting an "Incredibly Quiet Desktop" packaged in a small box which includes the CT-479 Adapter, HSF with clips and a power cable to connect a 4-pin Molex. The adapter is housed in its own plastic case and the HSF in a box. If the power cable had been sleeved, it would have been a nice touch. Included of course are the installation instructions, which has diagrams for installation. ASUS prints a warning on the back of the box, and in the instructions, not to use unqualified processors or motherboards, this may cause permanent damage to the product and other components.

Installation ASUS CT-479
http://www.techpowerup.com/reviews/ASUS/CT-479/images/backadaptersmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/backadapter.jpg)
The backside of the adapter of course is pinned out like a socket 478 CPU. The installation of the adapter is as easy as installing a CPU actually. Line up the adapter with the socket.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapter1small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapter1.jpg)
With the lever up sit it down in the socket and close the lever.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapter2small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapter2.jpg)
After verifying the adapter is seated properly and the screw lock is in the open position.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/cpu3small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/cpu3.jpg)
Then line up the processor, set it in the socket of the adapter and turn the screw lock.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/cpu2small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/cpu2.jpg)
As you can see the adapter takes up the whole area on the side of the socket which for most enthusiast will be an issue when it comes to mounting water cooling. The adapter blocks the two screw holes on that side. Too bad the designers didn't even out the components on both sides.
Most, however, have already figured out different mounting techniques. Take note if you are going to use something other than the provided HSF from ASUS, which I would suggest if you plan to get the most out your upgrade, is to place some protective pads or soft foam pad on the chip, since it has no IHS (Integrated Heatspreader). The processor's die chips very easily. I used a thermal pad from the Chipset of an old motherboard.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/jumpers_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/jumpers.jpg)
The jumpers present on the adapter are to set the bus speeds for the 400 MHz and 533 MHz processors. I did experiment with these by setting them to both settings and without any jumpers. Didn't make any noticeable difference for me.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/hsfplugsmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/hsfplug.jpg)
To complete our process we need to line up the HSF's slot with the power plug and jumpers. The included HSF comes with its own pre-installed thermal pad and a soft foam pad to protect the processor. Plug in the adapters power cable to the adapter, clip the hold downs on and plug in the fan.
That completes the installation of the adapter. Because of the added height of the adapter we're not able to use an after market HSF without modifications. Now the included ASUS HSF is made of all aluminum and is my only gripe. Understanding that ASUS marketed the adapter as an upgrade that is "Incredibly Quiet"; as we saw written on the box may explain for the lack of a better performing HSF. Perhaps a round copper insert in the middle of the HSF would have provided for a more robust HSF.
Of course at stock speeds and default voltage the included ASUS HSF does the job it was intended to do.

Installation Guide
The packaging used for the Booster is orange and proudly displays OCZ with the same print on the front and back. They chose to use egg crate foam to protect the contents. This provides excellent protection against those nasty bumps in the road during shipping.
Included is the Booster and ATX12V 20 pin Power Cable Adapter, along with Installation Guide and Motherboard Compatibility List. It's interesting to see OCZ state a VDIMM boost up to 3.9V on the package, when none of the boards on the compatibility list shows being tested to said voltage.
We can look into that after installation. Again my personal preference would have been sleeves on the power cables.
[Page=Installation OCZ Booster]
Installation OCZ Booster
http://www.techpowerup.com/reviews/ASUS/CT-479/images/install5_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install5.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/install3_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install3.jpg)
The Booster's installation is straight forward with inserting the Booster in the memory slot as you would a memory stick.
I chose to plug in the two 4 pin Molex prior to inserting the booster in the memory slot. Because I had the motherboard out for the review it was easy to insert.
The Installation Guide informs you that the Booster may not fit certain motherboards due to variations between motherboard socket placement and other electronic devices nearby. For instance the P4P800-E memory location is towards the end of the motherboard, the height of the Booster, as seen in the side view, may make installation in a small case difficult if you're to close to the drive bays.
Some considerations to keep in mind if you intend on using the Booster.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/install4_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install4.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/install1_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install1.jpg)
The Molex are labeled L (left) and R (right) with color coded dots to make it dummy proof. After you have inserted the Booster and plugged in the two 4 pin Molex you would then plug in the male side of the ATX12V 20 pin Power Cable Adapter into the motherboard. Take note if you have a 24 pin connector on your PSU, you'll need the split type 24 pin connector.
Another potental issue with the PSU is, that a -5V line to the power connector is required for operation of the LED. As luck would have it, the Thermaltake TWV I'm using does not have that line. Which for me really didn't matter since I can not see the LED once the Booster is installed. Something that would be a minor issue for some, since I'll read voltage from my multimeter anyway.
This brings us back to my comment earlier about the VDIMM of 3.9V displayed on the box. The Booster is warranted up to 3.9V and certain chipsets/motherboards may allow for higher. Let's say I can confirm 3.9V with this chipset/motherboard and then some. The Booster does have a small screw under the LEDs for adjusting the readout if calibration was knocked out during shipping.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/install2_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install2.jpg)
Last we need to plug in the female end of ATX12V 20 pin Power Cable Adapter to the PSU male ATX12V 20 pin connector.
Now do take the time to read the Installation Guide, especially the Warnings and Disclaimers.
You need to make sure the Voltage Adjustment knob is turned as far counter-clockwise as possible before you fire up your rig. I found the lower I set the voltage in the BIOS, the less sensitive the voltage adjustment knob was to adjust. Adjustments should be done while in the BIOS. Above 3.4V active cooling should be used.

Everest Read and Write again shows a stock PM 750 is out of its league. Even OC'd the PM 750 doesn't match the P4, but the Booster does show off tighter timings. Everest Latency is a different story all together with the PM 750 Booster sporting a 48.8ns.

<td>Compare this to the price of the native Socket 479 boards and this configuration is still cheaper, even if you had to purchase the ASUS motherboard. The adapter solution with the ASUS motherboards also delivers Dual Channel DDR400 Memory and AGP 8x, something the native boards with AGP do not. Without Hyperthreading this configuration lacks real power for some CPU hungry apps.<br />
But if you're a gamer like me, this upgrade adds new life to a chipset that is fading fast and allows it to compete against the higher end chips from Intel and AMD.<br />
Want to move up to PCI-E? ASUS has i915P motherboards (P4GD1 & P4GPL-X) with PCI-E that also work with the CT-479 adapter. Not to mention that at the time of this review the prices for Intel Mobile chips are at their lowest ranging from a PM730 for $199.00 to a PM770 for $430.00. Kudos to the ASUS engineers for their design of the CT-479 adapter, indeed one of a kind.</td></tr>

Too bad my Pentium M 750 doesn't boot at 200 MHz in the BIOS. This would have given me access to some more memory dividers which I could have taken advantage of with the DDR Booster. None the less I was able to take advantage of tighter timings and the CPU multi had been useless until I was able to tighten the timings. This is also the reason I didn't use the DDR Booster with the P4 3.2E. It would not have been able to scale the TCCD memory used in our review to make a difference in its overall scores.<br />
If you are considering the ASUS CT-479 Adapter I would certainly go for the added kick in the rear with the OCZ DDR Booster. Hats off to the OCZ engineers for stepping up to the plate and providing a device others would not.</td></tr>

We are going to take a look at the ASUS CT-479 Adapter which allows you to use an Intel Mobile Processor in your desktop. This Socket 478 to Socket 479 converter is considerably less expensive than the native Socket 479 boards, which you will not find for less than 200 US dollars at the time of this review.

What this review will focus on is the performance between the ASUS P4P800-E with a P4 3.2E Prescott and the ASUS CT-479 adapter with a Pentium M 750 Dothan.
It is possible to get higher clocks out of this board by doing the vdroop and vdimm voltage mods, however since most of our readers will just install the adapter and not do the mods, I decided not to do them for the review. Instead, as an extra bonus, I'm going to review the OCZ DDR Booster along with the ASUS CT-479 Adapter.

There's nothing like a one two punch, and since we are teaming the ASUS CT-479 with the OCZ DDR Booster they should be nothing less. Using OCZ PC4000 Dual Channel Gold (http://www.ocztechnology.com/products/memory/ocz_el_ddr_pc_4000_dual_channel_gold_rev_2) memory with the DDR Booster should allow us to run the memory at a higher voltage for tighter timings and with OCZ's EVP (Extended Voltage Protection) we can run these modules at 3.0V without voiding their Lifetime warranty, and not voiding the warranty on the motherboard with a VDIMM mod.
What is a DDR Booster you ask? Well the official name to start with is the DDR Booster Diagnostic Device. The device is designed to provide cleaner power to create a more stable memory environment. Plugged directly into the PSU, the booster allows you to adjust the VDIMM, in certain circumstances up to 3.9V. Equipped with an LED to show VDIMM readout the Booster operates in and takes up one memory slot, which may not sound appealing to some. If you've looked at the native Socket 479 motherboards none have more than two DDR1 memory sockets, thus another point for the ASUS solution.
Take note of the OCZ Booster compatibility below, these are only the boards that OCZ has tested in house, but that does not mean it will not work with other models. A quick email to OCZ support would clarify any concerns. Having dealt with their customer service personally, I can contest it's second to none.
Supported CT-479 motherboards listed on DDR Booster Compatibility List
P4P800-E
P4C800-E
Important notes for DDR Booster Compatibility
Use of the DDR Booster with certain chipsets/motherboards may limit maximum DIMM population.
VTT mod may be needed to reach above 3.0 VDIMM
Power supply quality may affect DDR Booster performance and stability.
DDR Booster power adapter may not fit all Levicom Power Supply models due to Levicom's use of a non-standard ATX adapter.
Power supplies used in conjunction with the DDR Booster must support a -5V line in order for the LED readout to function.
The OCZ Booster requires a 20-Pin ATX connector and will not work with power supplies that have 24-Pin connectors

Packaging ASUS CT-479
http://www.techpowerup.com/reviews/ASUS/CT-479/images/displayedsmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/displayed.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/contentssmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/contents.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/boxsmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/box.jpg)
The packaging is pretty laid back with ASUS promoting an "Incredibly Quiet Desktop" packaged in a small box which includes the CT-479 Adapter, HSF with clips and a power cable to connect a 4-pin Molex. The adapter is housed in its own plastic case and the HSF in a box. If the power cable had been sleeved, it would have been a nice touch. Included of course are the installation instructions, which has diagrams for installation. ASUS prints a warning on the back of the box, and in the instructions, not to use unqualified processors or motherboards, this may cause permanent damage to the product and other components.

Installation ASUS CT-479
http://www.techpowerup.com/reviews/ASUS/CT-479/images/backadaptersmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/backadapter.jpg)
The backside of the adapter of course is pinned out like a socket 478 CPU. The installation of the adapter is as easy as installing a CPU actually. Line up the adapter with the socket.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapter1small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapter1.jpg)
With the lever up sit it down in the socket and close the lever.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapter2small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/adapter2.jpg)
After verifying the adapter is seated properly and the screw lock is in the open position.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/cpu3small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/cpu3.jpg)
Then line up the processor, set it in the socket of the adapter and turn the screw lock.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/cpu2small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/cpu2.jpg)
As you can see the adapter takes up the whole area on the side of the socket which for most enthusiast will be an issue when it comes to mounting water cooling. The adapter blocks the two screw holes on that side. Too bad the designers didn't even out the components on both sides.
Most, however, have already figured out different mounting techniques. Take note if you are going to use something other than the provided HSF from ASUS, which I would suggest if you plan to get the most out your upgrade, is to place some protective pads or soft foam pad on the chip, since it has no IHS (Integrated Heatspreader). The processor's die chips very easily. I used a thermal pad from the Chipset of an old motherboard.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/jumpers_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/jumpers.jpg)
The jumpers present on the adapter are to set the bus speeds for the 400 MHz and 533 MHz processors. I did experiment with these by setting them to both settings and without any jumpers. Didn't make any noticeable difference for me.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/hsfplugsmall.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/hsfplug.jpg)
To complete our process we need to line up the HSF's slot with the power plug and jumpers. The included HSF comes with its own pre-installed thermal pad and a soft foam pad to protect the processor. Plug in the adapters power cable to the adapter, clip the hold downs on and plug in the fan.
That completes the installation of the adapter. Because of the added height of the adapter we're not able to use an after market HSF without modifications. Now the included ASUS HSF is made of all aluminum and is my only gripe. Understanding that ASUS marketed the adapter as an upgrade that is "Incredibly Quiet"; as we saw written on the box may explain for the lack of a better performing HSF. Perhaps a round copper insert in the middle of the HSF would have provided for a more robust HSF.
Of course at stock speeds and default voltage the included ASUS HSF does the job it was intended to do.

Motherboard Compatibility List
Installation Guide
The packaging used for the Booster is orange and proudly displays OCZ with the same print on the front and back. They chose to use egg crate foam to protect the contents. This provides excellent protection against those nasty bumps in the road during shipping.
Included is the Booster and ATX12V 20 pin Power Cable Adapter, along with Installation Guide and Motherboard Compatibility List. It's interesting to see OCZ state a VDIMM boost up to 3.9V on the package, when none of the boards on the compatibility list shows being tested to said voltage.
We can look into that after installation. Again my personal preference would have been sleeves on the power cables.
[Page=Installation OCZ Booster]
Installation OCZ Booster
http://www.techpowerup.com/reviews/ASUS/CT-479/images/install5_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install5.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/install3_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install3.jpg)
The Booster's installation is straight forward with inserting the Booster in the memory slot as you would a memory stick.
I chose to plug in the two 4 pin Molex prior to inserting the booster in the memory slot. Because I had the motherboard out for the review it was easy to insert.
The Installation Guide informs you that the Booster may not fit certain motherboards due to variations between motherboard socket placement and other electronic devices nearby. For instance the P4P800-E memory location is towards the end of the motherboard, the height of the Booster, as seen in the side view, may make installation in a small case difficult if you're to close to the drive bays.
Some considerations to keep in mind if you intend on using the Booster.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/install4_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install4.jpg) http://www.techpowerup.com/reviews/ASUS/CT-479/images/install1_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install1.jpg)
The Molex are labeled L (left) and R (right) with color coded dots to make it dummy proof. After you have inserted the Booster and plugged in the two 4 pin Molex you would then plug in the male side of the ATX12V 20 pin Power Cable Adapter into the motherboard. Take note if you have a 24 pin connector on your PSU, you'll need the split type 24 pin connector.
Another potental issue with the PSU is, that a -5V line to the power connector is required for operation of the LED. As luck would have it, the Thermaltake TWV I'm using does not have that line. Which for me really didn't matter since I can not see the LED once the Booster is installed. Something that would be a minor issue for some, since I'll read voltage from my multimeter anyway.
This brings us back to my comment earlier about the VDIMM of 3.9V displayed on the box. The Booster is warranted up to 3.9V and certain chipsets/motherboards may allow for higher. Let's say I can confirm 3.9V with this chipset/motherboard and then some. The Booster does have a small screw under the LEDs for adjusting the readout if calibration was knocked out during shipping.
http://www.techpowerup.com/reviews/ASUS/CT-479/images/install2_small.jpg (http://www.techpowerup.com/reviews/ASUS/CT-479/images/install2.jpg)
Last we need to plug in the female end of ATX12V 20 pin Power Cable Adapter to the PSU male ATX12V 20 pin connector.
Now do take the time to read the Installation Guide, especially the Warnings and Disclaimers.
You need to make sure the Voltage Adjustment knob is turned as far counter-clockwise as possible before you fire up your rig. I found the lower I set the voltage in the BIOS, the less sensitive the voltage adjustment knob was to adjust. Adjustments should be done while in the BIOS. Above 3.4V active cooling should be used.

Stock the PM 750 is no match for the P4 in this CPU test. However stoke up the OC on the PM 750 and it stretches past the P4. The opposite occurs in the Arthmetic Float bench with the oc'ed P4.

Everest Read and Write again shows a stock PM 750 is out of its league. Even OC'd the PM 750 doesn't match the P4, but the Booster does show off tighter timings. Everest Latency is a different story all together with the PM 750 Booster sporting a 48.8ns.

SuperPi tests CPU and memory, with the Booster PM 750 turning in some very respectable numbers. Even in the 32M bench, which I expected the P4 to post up better than the PM 750, but the Booster PM 750 turned in the best scores.

Another bench I thought the P4 would come ahead. Surprisingly both the OC'd PM 750 and the Booster PM 750 post up above the P4. Please note, that the Pentium M does not have HyperThreading.
3DMark 2001
http://www.techpowerup.com/reviews/ASUS/CT-479/images/3dmark2001.gif
The PM 750 shines in the 3DMark01 benchmark with the Booster PM 750 just shy of 32k. With the stock PM 750 sneaking out of last place.

<td>Compare this to the price of the native Socket 479 boards and this configuration is still cheaper, even if you had to purchase the ASUS motherboard. The adapter solution with the ASUS motherboards also delivers Dual Channel DDR400 Memory and AGP 8x, something the native boards with AGP do not. Without Hyperthreading this configuration lacks real power for some CPU hungry apps.<br />
But if you're a gamer like me, this upgrade adds new life to a chipset that is fading fast and allows it to compete against the higher end chips from Intel and AMD.<br />
Want to move up to PCI-E? ASUS has i915P motherboards (P4GD1 & P4GPL-X) with PCI-E that also work with the CT-479 adapter. Not to mention that at the time of this review the prices for Intel Mobile chips are at their lowest ranging from a PM730 for $199.00 to a PM770 for $430.00. Kudos to the ASUS engineers for their design of the CT-479 adapter, indeed one of a kind.</td></tr>

<td>The price for the OCZ DDR Booster is starting to come down with its novelty wearing off. As of the time of writing this review, I'm only using 2x512 MB sticks of memory so I'm not affected by the loss of a memory slot.<br />
Also at the time of this review OCZ announced the new PC4000 EB Platium 1024 Edition. Some will say "Blah" I'll do the vmod myself, but for me it was a nice change to just plug in and go. Let alone no need to worry about the motherboard's warranty.<br />
Too bad my Pentium M 750 doesn't boot at 200 MHz in the BIOS. This would have given me access to some more memory dividers which I could have taken advantage of with the DDR Booster. None the less I was able to take advantage of tighter timings and the CPU multi had been useless until I was able to tighten the timings. This is also the reason I didn't use the DDR Booster with the P4 3.2E. It would not have been able to scale the TCCD memory used in our review to make a difference in its overall scores.<br />
If you are considering the ASUS CT-479 Adapter I would certainly go for the added kick in the rear with the OCZ DDR Booster. Hats off to the OCZ engineers for stepping up to the plate and providing a device others would not.</td></tr>
