RAM causing system freeze (I think) but why?

post #1 of 19
Thread Starter 
My sig rig (specs below) is / was freezing every hour or two. The freeze often causes white noise from the speakers and the system doesn't unfreeze itself even after 45 minutes.

I clean installed two days ago but had two freezes within 30 minutes.

Using the MS diagnostic utility on the Win 7 disk, I ran 17 memory tests with zero errors. Everything at stock volts and speeds. The freezes are apparently random as it's not under heavy use, with a particular program or anything like that. In fact, I ran Prime, Furmark and GPU video encoding simultaneously; couldn't reproduce the freeze.

Having removed two sticks of RAM, the system's been fine. With different two sticks, the system's been fine.

Powersupply issue? I'd have thought the Furmark, CUDA and Prime would test the PSU?

Would bad RAM slots cause it?

My mobo handbook says to use slots 1 & 2 for two sticks. Can I use 3 & 4?

Am I likely to need to up the volts to the RAM for it to be stable at stock speeds? If so, what's a sensible voltage to use?

Thanks a lot

Edit: Windows error log only says Kernal Power Fault which, google tells me, is simply me having to do a hard reboot following the total freeze.

GO into your bios and select the memory test and restart your computer, see if it passes.

Will do, although I don't think there is one... hence the Windows Memory Diagnostic.

Should I do it with four sticks back in?

Run Memtest with each individual stick
post #6 of 19
Thread Starter 
My bIOS doesn't have a mem test utility.

Using the Windows 7 one though, it passes with individual sticks and all 4 sticks.

:Confused:

Is it possible that the RAM needs extra volts to run at stock?* My PC hasn't frozen for 4 days or so running with only 2x2Gb so it's pretty safe to say that it's something RAM related.

If so, what's a safe and small voltage to try?

Thanks for the replies.

He was talking about the program you can download called Memtest86+

You might need to raise the voltage to the IMC. Up the CPU-NB voltage a tad, say in the range of 1.2 to 1.25. Can add stability when running four sticks of ram. Others will say that you can go higher with that voltage as well.

Can you please tell us what is your current DRAM voltage and CPU-NB voltage?

Sorry for the slow reply.

Here are all of the voltage settings. Taken from the voltage monitoring in the BIOS, not any 3rd party app.

CPU - 1.346v (C&Q is enabled, don't know what the low frequency voltage is)
CPU / NB 1.111v
CPU VDDA - 2.487v
DRAM - 1.601v
HT - 1.204v
NB1.8v Voltage - 1.812v
SB - 1.204v
3.3v Voltage - 3.361v
5v Voltage - 4.495v
12v Voltage - 12.427v

I know / think that IMC is Internal Memory Chip* - is the voltage to this controlled by the CPU-NB voltage? How will this affect the temps? Only the NB, or the CPU too? I have passive cooling on the NB.

*is this the go-between for RAM and CPU?

Thanks a lot



Mike

What Memory speed? and is it DDR2 or DDR3? using 4 sticks can cause problems... DDR3 you can only run 1066 on 4 sticks, DDR2 you can only run 800 on 4 sticks.
