We did not receive the memory in a retail package, that's why we are showing you the A-DATA Vitesta DDR2-800 package here, the 1066+ package will be similar.

The memory modules come with the typical red Vitesta heatspreader which dissipates some heat of the memory chips. Even during overclocking the memory modules do not get very warm, so this cooling is absolutely sufficient.

After carefully removing the heatspreader we can see that eight BGA memory chips are used on each side of the PCB for a total of 16.

The sticker on the memory module shows only the rated frequency and the timings. It would have been nice if the voltage and capacity were indicated here as well.

The memory chips are made by Micron on a Brainpower PCB and do not have any further information like frequency printed on them.

Since we are testing this memory on the ASUS P5B we will use a Write to Precharge Delay setting of 13 as suggested by A-DATA.
Performance
As always, the first test is how the memory performs at the standard frequency of 400 MHz, with standard voltage of 1.8V. The second and third tests are at 400 MHz too, but with different timings of CL5 and CL3. Here you can easily see how much difference changing the timings makes.
Next we tried how fast we could get this memory to run at CL5 with voltages of 1.8V, 2.05V, 2.25V and 2.35V. 1136 MHz at 2.35V is quite impressive.
The next four tests show how well the memory performs at standard CL4 timings over the same wide range of voltages. Even at the standard voltage of 1.80V this memory can run 800 MHz DDR2 which is important if you plan on running on a cheaper motherboard that supports no memory voltage control.
What if you don't need extremely high MHz, but want good timings? We tested to see how far the timings could be tightened. The fastest setting we could reach was 3-2-2-4 which is the fastest setting that is available by the chipset. However, to get acceptable clocks out of the memory at CL3 you need to increase the voltage quite a bit.

Wow! Even though the memory is officially advertised as a CL5 product, it works really great at CL4. With only around 2.25V required to go beyond DDR2-1000 @ CL4 this memory looks like it will be a great product for overclockers. The CL4 setting also seems to be a sweet spot that balances frequency and performance, since the CL3 setting just does not have enough clock headroom.<br />
If you are set out to reach as fast clocks as possible, then use CL5 and see your memory easily break DDR2-1100. Not fast enough? Go for CL6 at well over DDR2-1200.<br />
The price tag of $464 for a 2 GB kit seems to be justified and is well within range of other comparable memory kits.
