RAM not running at right speed ... HELP!!!

[mikey8684]

Hi guys,

I just recently upgraded to the system on the left

<<<<<

The problem is that my ram is only running at 667 and I cant figure out how to get it to run at its normal 800.

Any help would be appreciated.

I have the latest bios for my mobo both the bios and windows registers that I have 4GB ram but they both also say its only running at 667 :(

The mobo supports upto 1066 and upto 8GB so im a bit stuck :S

PLEASE HELP :respect:

You need to set a memory divider to change the ratio between the FSB and the RAM. CPUz will tell you what the ratio is at the moment, then adjust accordingly.

CPUz is saying

400MHz
1:1

hopefully I can work it out

Go to MIT in bios and it looks from the manual you need to change the "system memory multiplier(SPD)" to allow for different speeds. I believe when you change this you then should see the actual ram speed right below it change to a different MHz.

Look to page 53 in the motherboard manual to see what I am referring to!

Edit: if CPU-z says 400MHz that is only a sindgle reading...the DDR value is double what CPU-z reads, so if in fact it says 400MHz, you are at DDR2 800 speed!

Ok yeah I have seen that in the bios and gone thru the manual.

The bios lists it as 667 800 when I set the SPD to 2.00 ... when set to auto it lists 667 1000 ???

Could it have anything to do with my CPU overclock ? 400x8 @3.2GHz .... would it do anything if i put it to 800x4 @3.2GHz ??? or would it implode lol

Look in CPU-z, as you stated, it looks to be right. I ran my E6400 at 1:1 with the ram, and at 3.2GHz or a 400FSB the ram is ready to rock at 400MHz or DDR800 (DDR=double/dual data rate). CPU-z shows half of the DDR value!

ahhhh ok that makes sense.

BUT

why does 3DMark Vantage only list my ram as being 667 ?

Could be a misread. I go with CPU-z for fact...dont wory so much how it gets read in ORB. I have had CPU and GPU misreads from time to time, so the ram isnt too strange in my eyes!

I think the two speeds are what you have now and what you will get with the change. If you set the ratio to 2.0, you should get 800.
