Just bought new RAM, question

post #1 of 4
Thread Starter 
So I just bought some new RAM and the defaults for it in the BIOS were different than that the RAM advertised. That's fine; I changed what I knew to what it should be (was DDR3-1066MHZ, 7-7-7-20, 1.35V; is now the DDR3-1600MHz, 9-9-9-24, 1.5V it should be). However, I started up the Intel Extreme Tuning Utility after and it "suggested" that I change the Uncore voltage to 1.35V and change some other timings that I have no idea about.


The things it wants to change are colored Orange in the pictures below. Should I change those? (I don't know what Uncore voltage should be relative to the Memory Voltage)
tRRD is currently 5, tWR is 10, and tFAW is 30. I don't know what those are either.

Thanks for your help

Specs if they help:

MB: Asus Sabertooth x58
CPU: i7-950
RAM: 24gb Corsair VENGEANCE PC-12800
GPU: GTX 580
PSU: 1100 watts

I believe that the uncore voltage is the QPI/DRAM voltage which controls the IMC (Integrated Memory Controller). I would start at 1.3 uncore voltage and then test with p95 with 95% RAM used using custom blend. If it passes 12 hours, you're all good to use the PC or try to tighten the timings (WARNING: May cause the PC to become unstable). If it doesn't pass (BSOD 0x9c), up the uncore voltage by a notch and then test again. Report back here when you have problems.

Unfortunately, I can't run Prime95 for more than a minute because I use the Intel Stock cooler that came with the CPU. The CPU heats up to above 80 quickly and I have never dared to let it go higher than that before stopping the test.

Thanks for the answer though, just wanted to make sure the 1.35V wasn't an unreasonable amount.

I would make 1.35 as your max QPI voltage. Going anything over that is killing the IMC to me. It's really up to you when you want to stop, but I heard Intel increased the QPI safe voltage to 1.375.
