I have some ddr3 from ADATA, these, and they are rated at 1600mhz, with 9-9-9-24, but I cannot get it to run at that.
I have an MSI-e33 H55 mobo, and i don't know if that is the problem, I have my fsb @ 200, and my cpu multiplier 21, and that is rock stable, but when I try to overclock the ram and run intel burn test them my pc crashes. Also my temps seem fine, ~30c idle, and less than 60c after two hours of intel burn test.
Thanks, the rest of my system is as follows;
CPU-g6950 @ 4.2ghz with hyper 212+
PSU-Antec Neo Eco 520w
GPU-Integrated Intel Graphics
Note: This was my first build, so no previous experience overclocking.
@ RJR: I wish I could if it is an actual ram problem, not me, but I have had this build for a while, early Mayish, so I cannot take the ram back. I got a cooler about a month ago so I decided to try to overclock.
@ ekoostik: Like I said, I have the FSB at 200, and when I have the memory ratio to 4, it automatically sets it to 1600mhz, and I set the QPI ratio to 16, it sets that to 4800mhz, I have the voltage set at 1.65, that is all I changed.
Try bumping up your QPI/Vtt voltage. Is it currently at 1.1? Try setting it to 1.15V. It's typically recommended to keep it no less than 0.5V below your DRAM V (1.65 - 0.5 = 1.15V) if stability is an issue. Intel states the QPI / Vtt typical V is 1.1V, the max is 1.155V while the absolute max is 1.4V (though you should not need to get near this).
