It was running at 4,5GHz? Whoaa! I tought it was around 4,2GHz.
No wonder it crashed so often. I would have only clocked an extremely well ventilated gaming machine that high and that only because I shut my machine down for the nights, so it's not at continuos burn. But a server... A bit too extreme.
And over time the dust collected into the CPU and other fans really will have temperature rising to the levels where BSOD will happen. It has happened to me couple of times even with a more modest overclock.
Do you majkp de-dust it at regular intervals?
Well. I'm glad you guys found out. And it's very good that it was caused by an OC because you can control that whereas if it would have been program/script/software problem it might not have ever been figured out.
