[mryo210]

My system is AthlonII x4 640,M4A785TD-V EVO and F3-12800CL9D-4GBRL
This system can work properly at stock frequency
but,my problem is I can't set FSB over than 210 at ram speed 800,667 and 533.PC will not boot.
But if I set ram speed at 400.I can set FSB at 255 and system is stable.If FSB over 255
,it will not boot also.
I setting ram timing as 9-9-9-24 follow spec.And try to increase ram over voltage,but it is
still not work.
Could you please tell me how can I do..

Do you have command rate at 2T or 2N, if it's at 1 maybe having problems......if that's not it could you post your BIOS Settings

[mryo210]

I think there is no command rate setting in this bios setting. please see my bios setting in these image.

Are you running the 0505 BIOS?

[mryo210]

yes, I use 0505 version but previous version was same problem.

It appears that ASUS has neglected to put the Command Rate in the BIOS, what you may want to try is loosen the timings and raise the tRFC..or..a better solution may be to reduce the speed and tighten the timings until ASUS can get the BIOS issue resolved...Anumber of others are having trouble w/ the lack of Command Rate issue also, see:

Set VDDNB Voltage to AUTO. Set HT Over Voltage to 1.30V. Set Memory Over Voltage to 1.60V. Keep us posted on the results and we will be able to further assist you.

Thank you

have a read, either you will have to wait for bios upgrade whenever they test this ram or buy new ram in the QVL.
