I thought my computer was rocking DDR3 @ 1600 until I upgraded to a EVGA GeForce GTX 570. According to EVGA the card is much more sensitive to memory settings than my older card. Well, I guess I hard-set the timings, but the mobo had other settings which limited the RAM. The graphics card "worked" and always passed tests, but the framerate is terrible and I'd receive an occasional BSOD due to memory management. However, several memtests never returned any errors for the RAM (both together and individually). I found that the board/BIOS was limiting the RAM to 1333. I've can't seem to tweak the settings in BIOS to get it to run at 1600 without hitting something that prevents the computer from booting. I've attempted to get help from both the RAM and mobo manufacturer, but they're pointing fingers at each other (though ASRock support suggested upgraded the BIOS to take care of some known dual-channel issues, which did seem help, a little). I know what the RAM settings are supposed to be, but some of the terminology in the ASROCK BIOS is unfamiliar to me. I hope the ASROCK die-hards here can help.
So my question is, how can I perfectly set my motherboard to meet all the necessary specs? I'm not looking to OC, at this point, I'd be happy to just get what I paid for, ya know?
Bonus question... the RAM specifies 1.65V, but the mobo only offers something like 1.645 and 1.659. Shoot high, or low?
Thanks for your help!
