This might send odd but I have my GPU memory and core OCd and I generally find that if I turn the machine on and jump straight onto some gaming at the OC values I get a driver crash. If I wait a bit and run the game at stock then crank it up it all works fine. Does hardware work this way at all? If so how and why?
 
It runs the heaven stuff well and plays games for hours. It just crashes when I first start the machine up with it OCd.

My stability testing Involved running the heaven valley for a while an playing games.
 
I had this same thing with my 680 Lightnings. If I benched with my stable overclocks, it would bug out almost immediately but if I ran the bench with no overclocks first and then went big, it was fine.

Not sure if it was because I was under water and the vrms needed warming up or just the way it is on some cards and I never did get to the bottom of it.
 
AFAIK - most electronic components work better once they are warmed up - Hi-Fi amplifiers spring to mind as a good example. I leave my pre amp and CD player switched on 24x7. They definitely sound and perform better imho.

Don't see why this would not be the case with Pc components also.

Unless your using ultra high end watercooling or LN2/phase I can't really see this being the case.

More likely its not stable but the method your using is skating around the instability thats causing a more immediate crash.
 
Liquid nitrogen cooling mate, the preserve of high end benchmarkers with cherry picked components. 8 pack on ocuk here is such a user, primarily with cpu's and memory from my reading here. But id say he knows about gpu clocking too.
 
No probs mate. exotic cooling like ln2 or phase is only for hardcore users. For the rest of us normal guys it's high end air cooling or custom watercooling. The latter im tempted by, my 3770k is a hot runner. Though i might just delid it.

Ok, here comes another question. :D

What does 'delid' mean? I'll hazard a guess, and say it might have something to do with taking a thin layer off it for better temps?

(Sorry OP). :)
 
You have the chip itself soldered to the PCB then often it has a metal (or sometimes ceramic) cover glued over it (usually a heat spreader) that provides not only some protection for the chip but a bigger surface area for heat transfer away from the chip.

Delidding means either removing that entirely or cutting the top off to expose the chip theoretically so you can get a better interface with high end cooling equipment for more efficent heat transfer.
 
Delidding a 1155 cpu means taking off the ihs sheid, cleaning off the thermal paste that intel stuck between the die and the ihs. Then replace it with better aftermarket stuff. Coolaboratory liquid pro/ultra does best. Upto 20c temp drops, but warranty is gone. And that paste has to be applied extremely carefully. It's even pretty good just on the ihs, but it does stain the cpu and the heatsink base. Yes, worth it cause no other stuff can compare.

I would have always said the same Rroff but very weird with my Lightnings. Starting from cold would result in a bug once the cards were warmed up, no problems. It could have been those clocks were not stable but after running 3DMark on stock, I could run my 24/7 clocks all day long with no issues/bugging out.

Anyone else got a theory?
