Hey guys,

So I've been getting random BSODs for quite a while now. It used to be that they only happened maybe once a month, if not even less frequently, so I didn't really mind, but now they're happening quite often.
I believe that putting the CPU under load makes the problem more likely to occur, because when it happens, it's almost always when I'm playing Crysis Warhead. Other games don't really seem to exacerbate the problem like that; maybe because Crysis is so much more demanding.
The reason I just got for the last BSOD was IRQL_LESS_THAN_NOT_EQUAL_TO, if I remember correctly. I actually don't recall seeing this one in the past; usually the BSOD says something about a clock interrupt signal not being received on one or more processor cores.

My PC is otherwise stable. I've gone out of town before and left it on and it was still running when I came back. It seems there are some very rare BSODs that are completely random, but other than that, just when I'm playing Crysis. I don't really do anything else with my PC that's as processor-intensive as Crysis, however I've attempted to reproduce the BSODs by running consecutive CineBench benchmarks to keep the proc under load. This was not successful at reproducing the problem. There doesn't seem to be any particular thing I can do in Crysis to produce it, either, although the BSODs do always seem to come in response to some event, such as an explosion. Sometimes I can play for a good hour or more without any problem.

I never had this problem before I overclocked, and, as a first-time overclocker, I followed some instructions on a website to the letter in overclocking, EXCEPT for the QPI/DRAM voltage - when I followed the tutorial in raising that, I got BSODs left and right. Here's my hardware:
CPU: Core i7 920 - stock 2.67GHz OC to 4.0GHz
Mobo: Asus P6T Deluxe V2
Memory: Corsair XMS3 6GB (3x2GB) 1600MHz
GPU: HIS Radeon HD 4870 1GB
PSU: Corsair HX1000W

And the BIOS settings I changed:

SpeedStep and Turbo Mode: Off
BCLK: 200 MHz
CPU Voltage: 1.5V
DRAM Frequency: DDR3 1603 MHz
DRAM Voltage: 1.66V (BIOS won't let me set 1.65V or I would)

Thanks for any help or suggestions!

That is a very large overclock. What temperatures are you running?

The first thing you want to do is to try a smaller overclock. Try something a little less like 3.8 or 3.6 and then play your games and see if it continues.
