My 920 was at 4400 @1.55V yesterday idleing with temps at about 38C and it just cut off and rebooted itself then it hung just before windows could boot. So I decided to cut back to my reliable clock that I Primed at over 24hrs on which is 4.2 @1.5V. with temps idleing at about 36C. This morning I woke up and found that it rebooted again and hung just before Windows.

It's funny that if I was Primeing at 4.2 that it would probably never hang, but that it was idleing it just hangs. Could it be my voltage is too high ? Is this the cold bug ? I did move my rig to two feet of my AC to get more air, could this be condensation ? Does anybne know ?

I had the same problem with my 920 a while back where it would just reboot randomly.

I'm not exactly sure what caused it, but it is definitely a sign of instability.

Haven't had a single problem after I "tuned" my system.

Bump your Determination/ MCH voltage up.

My current "stable" setting is 295 FSB @ 1.45v.

With this setting I could prime for days, run games and everything else I do with my PC without a single hiccup.

I also figured out that a few of my "annoying" problems were video card related - so never rule out the video card.

Also weird display glitches could be monitor related as mine was.

For me, luckily I bought the goods from a local store so I could return the items during the trial and error process.

I am not clocking my video card, since I don't game, so I doubt that's it. My voltage will Prime, but once it's idleing and doing nothing it shuts down. I don't get it ?

What bios are you using? The latest I've seen is WD2P0704.

In the BIOS I find these settings work best:

JumperFree Config Menu : performance mode (standard) and MCH Voltage (1.60v)

CPU Configuration Menu : microcode updation (enabled) and all other (disabled)

Chipset Menu : hyper path 3 (disabled), link latency (normal), and PEG link mode (normal)

how long are you priming? at 4.4ghz i would say no less than 12-24hrs for stablity and another 12-24hrs for the memory to ensure stablity.

You also need to make sure your using two instances one for each core.

I am using bios 0606. I primed at 4.2 for over 24hrs dual instances too. I only primed 4.4 for 12hrs. It's the 4.2 setting I am concerned with. It was always stable at that speed, before recently.

have you memtested yet? i have seen in rare cases Prime stable systems that will crash. When memtested it reveiles that the memory was unstalbe.
