Hello,
I recently bought a new Mother Board (ASUS P5B) & Core 2 Duo 6600 @ 2.4GHZ:
ASUS P5B:
http://www.asus.com/products4.aspx?l1=3&l2=11&l3=307&model=1178&modelmenu=1
I installed the following Ram:
KINGSTON KHX6400D2/1G HYPERX 1GB PC6400 800MHZ
http://www.e-shop.gr/show_per.phtml?id=PER.554789
But, when the system boots up, at the American Megatrends Bios DOS screen, the memory is recognized as:
PC2-5300 667MHz and not PC2-6400 800MHZ!
I updated the Bios to 1007 from here:
http://support.asus.com/download/download.aspx?SLanguage=en-us&model=P5B
But the same problem persists!
I read in the manual:
http://support.asus.com/download/download.aspx?SLanguage=en-us&model=P5B
I can’t find any section on the BIOS menu where I could adjust the memory tiomings manually?!
But this specific Kingston RAM is mentioned as CL5, with timings:5-5-5-15, so this shouldn’t be happening!?
Also, in the manual, at the P5B Premium Series M/B Qualified Vendors List (QVL) DD2-800MHZ capability, Kingston 1GB DDR2-800MHZ is listed, but not my specific KINGSTON KHX6400D2/1G HYPERX 1GB PC6400 800MHZ model.
Is there any solution to this problem or should I change the brand of the RAM or even the M/B?
Please, any help will be highly appreciated!
Thanks in advance.

Due to chipset limitation, DDR2-800 with CL=4 will be downgraded to run at DDR2-667 by default setting. If you want to operate with lower latency, adjust the memory timing manually.
Some old-version DDR2-800/667 DIMMs, may not match Intel's On-Die-Termination (ODT) requirement and will automatically downgrade to run at DDR2-533. If this happens, contact your memory vendor to check the ODT value.
