D'oh. Been running RAM with wrong settings for months.

I never knew what that 4/8 beats thing did. I haven't changed it. Left it on 8, I think.

Edit: This led me to a RTFM incident. Just looked it up in my motherboard's manual and it says set to 4 beats for "64 Bit Dq". I have no idea what that means. A quick google suggests it might have something to do with single channel memory but I didn't turn up anything conclusive.

I told a lie. Was using 4 not 8.

No problems for a month but I've started getting reboots and BSODs again. The only thing that I can think of that's changed is the ambient temperature. It was warm when I last had problems and it's warm again.

Heavy load doesn't seem to do much so what do you all reckon? RAM chips getting warm? North Bridge (it's passively cooled)?

Have just put everything stock and increased the speed of the case fans a notch. We'll see what happens next.

Temps in speedfan after increasing the case fan speed look fine. Temp 1 36º, Temp 2 (CPU) 37º, temp 3 30°, Hard Disk 32º. Maybe I'd decrease the speed later and see if there's much difference.

Edit: Those temps are all idle.
 
OK - I'm fairly certain I pinned down these crashing problems. It seems to be sorted now (assuming it's not just the colder weather).

In short nVIDIA drivers - probably originally the ones I installed for Assassin's Creed (which I think were beta). Installed some WHQL ones a few weeks ago and I've gone from at least one (usually several) BSODs a day to none at all.

I'm rather annoyed I went through so much grief while doing my MSc dissertation, all for the sake of a game (which I didn't have time to play much because I was busy - GRR).
 
Was you able to see what the error was on the BSOD's, as it might have lead you to that conclusion much sooner?

Yep. 0x00000124 variants. People seem to get them for lots of reasons though so it was hard to pin down.
 
Wasn't the nVIDIA drivers. The BSODs came back after a while. I changed to an HD4850 and that didn't sort things.

Current prime candidate for the problem cause is a fairly big bit of fluff that was wedged in the socket under one of my RAM sticks. Just blew it out with compressed air last night.

Don't want to count my chickens because I've thought the problem was solved on several occasions. We shall see.
