Adding 6GB RAM Led to Unstable Overclock

post #1 of 17
Thread Starter 
I knew what was going to happen and I walked right into it, but I couldn't resist the price drop and the possibility to make a RAM disk for the swapfile or failing that, to sport 12 GB RAM. My previously stable overclock became a tad unstable as soon as I doubled my RAM, even though I took the precaution to buy the EXACT SAME brand, model, latency which is:
2 Kits of 6GB (3x2GB) Corsair Dominator DDR3 CMP6GX3M3A1600C7 with 7-8-7-20

As a result, I think I broke the stability since before RAM upgrading I was able to withstand 24-hours of Prime95 and now I get a random blue screen once in a while where it tells me the CPU sent an irregular clock or something, and I can't even complete a simple 3D-Mark Vantage run (it locks right in the CPU test). As for the temps, I idle at 55° and under load I'm in the mid 70s.

I was wondering if anyone can help me out fine tuning a setting to get back a stable machine, these are the current settings (that used to be stable with 6GB RAM):

Try raising the QPI/Dram Voltage to 1.4v.

You know what they say,

Mo ram, mo problems.

NB temps?

Going from 6GB to 12GB (and filling all 6 slots) with a 920/930, you'll often run into such an issue. It gets a lot more touchy when your CPU overclock is already near its maximum as well.

You might benefit from a couple notches up on:
  • CPU voltage
  • QPI/DRAM voltage
  • IOH voltage
QPI/DRAM is the first thing I'd try, but a small increase in the others might help bring it home for you.

@MrTOOSHORT + Sn0man: I am gonna try to raise the QPI/DRAM Voltage and report back.

@Bryst: I knew it was going to happen, and I was expecting a raise in NB Temperature due to the extrawork, strangely enough though it didn't happen it still hovers on 59° with no significant increase.

I had to increase QPI/DRAM (VTT) voltage to 1.40v with 6 DIMMs. With 3 DIMMs, I only needed 1.28v for QPI/DRAM.

I did some testing, had some improvements but I am not there yet.
I had to increase QPI/DRAM (VTT) to 1.40v, anything less I pass one single run of 3DMark Vantage (it used to crash on the second CPU test before completing the first run) but not a second run. NB temps are 60° idle and reach up to 70° under load.

Later on I'll re-test with QPI/DRAM (VTT) 1.40v, I was wondering if there's any other setting I can tune besides QPI/DRAM (VTT) since I wouldn't dare raising it too much.

mmm not good news. I am getting blue screens on random basis, even though before I was getting them all the times, now they are less frequent but still...

From what I could gather from the BSOD before it rebooted was:
"The CPU did not receive a clock interval" something...

Any pointers?

Add another notch or two off QPI/Dram voltage.

Your safe up to 1.45v for 24/7
