ASUS P6X58D Premium and G Skill F3-12800CL9-2GBNQ

[yellowstone]

My system is ;


CPU i7 920
Mainboard asus p6x58D premium
RAM G Skill F3-12800CL9-2GBNQ 3 x 2G
VGA Asus Ati 5750

I overclocked I920 to 3.8G ( x20.0 and 189.9Mhz), but I could not make ram to 800Mhz - now 759.7Mhz.







Please let me know how to make my ram to run at 800Mhz.
If possible please explain it easy words.

Best regards,

That's normal, I wouldn't worry about it. If you look at cpu-z screenshots taken by other people with that motherboard you will see similar Bclk readings(you memory speed is directly related).

Command Rate is at 1, might be holding speed down a bit, can try 2

BCLK 200 x 10 does not work? You may need to raise QPI.

BCLK 160 x 10, 133 x 12, should all work fine. The BCLK and multiplier must be correct to reach DDR3-1600. Obivously with BCLK 190, your options are DDR3-1520, DDR3-1900, and so on..

Thank you

After upgrade 200 x 20, I can get cpu speed 4G, but I could not boot windows 7 with ram speed 1603Mhz.

What is QPI/DRAM Core Voltage?

Thank you

Thanks for your kind attention.

After bios upgrade to 1301, the problem was fixed.
