667 or 800 Mhz for my system....


Recommended Posts

My current specs are in my signature. I currently have the dominator 10000 ram but I don't overclock, so now its running at 800mhz (default, any increase in mhz causes puter to not post), and is unusually slow, with some instability problems.

Memtest shows the ram being fine.

I thought I saw somewhere on these boards that because of my cpu(Intel QX6850 1333mhz), I should get the fastest 667 ram when not overclocking.

When I use the Memory Configurator it says to use TWIN2X2048-6400C4DHX 800mhz ram.

So which is right? I just want the fastest, yet most stable ram available for my system.

Please make sure that you have the latest Bios version and then load setup/optimized defaults and set the Dim Voltage to 2.4 volts and then set SLI Ready Memory to CPU Max and set the CPC/CR to 2T, then test with http://www.memtest.org one module at a time! If you still get errors, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However, if you get errors with both modules that would suggest some other problem and I would test them one up and or in another system or MB to be sure. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test.
