Hi, I have a new Asus M2N32-Sli Deluxe mobo and i'm trying to figure out how to best overclock it.

My question has to do with memory. In the newest 0501 bios the only memory settings are for the memory speed (Auto, 800, 667, 533, 400). If i overclock my cpu, will the memory speed stay at one of the 4 numbers, or will it scale up with the cpu overclock?

Also, i have corsair memory with EPP. When i select SLI memory there are several settings (Optimal, performance, high frequency).... Using high performance gives me lower latencies, but using high frequency seems to do nothing. What is high frequency?

Also, once you enable sli memory it gives you a setting just under it that says cpuoverclock and has percentages and cpumax. These don't seem to do anything. What are they.

Also, CPUZ doesn't seem to report my memory speed correctly. Is this normal?

Thanks.

It scales with the FSB so 400MHz is 1:1 and 800MHz is 2:1 Asus use clocks speeds rather then deviders as it easier for novices.

If my memory is ddr2 6400 (800mhz memory) would i select the 800mhz memory option in general? If i use that is my memory running at full speed? And if i select the 800mhz option and then overclock my cpu by increasing the FSB does the memory scale at the same 2:1 ratio ( a 10mhz increase in fsb would mean a 20mhz increase on the memory speed?)

Yes that is correct on all accounts.

Use the 533 or 667Mhz settings to find out the highest your CPU can handle then blend the two togeather.

I've played around a little:

I've done up to a 10% overclock: fsb 200--->220


I'm assuming that at 220 the memory is running at 880 DDR speed (4 x 220)?
CPUz doesn't show the correct memory speed for some reason, but if my math is correct 880 is the memory speed. Is there another program that would report the correct speed?


For the 533 or 667 speeds what is the memory ratio for those?

Thanks!

NOt sure some thing like 5:4 etc. It also depends on the multiplire used you need 10, 14,16,18 inorder to use the full 800+MHz clock.
