Forgot to add, if you have a coffee filter, use that to clean it. Doesn't leave behind any fibers.
Yeah, I read that in the pdf you linked to. Cheers
85oC will kill your chip.
You shouldn't need to raise the voltage at all to hit 4.5GHz, which is where I would aim for with that chip. The extra 200MHz will make minimal difference.
I gather that the fact that it hit 85 briefly will not be a problem in the long run. I mean, if I let it sit at 85 for a few days then I'm sure it wouldn't be good, but if it hasn't killed it already, I'm hoping it means that the chip is fine
So, it turned out that I had put way too little paste. Even though I had spread it evenly on the cpu, it had only contacted the heatsink in a semicirle around the outside of the chip, completely missing the crucial part where the cores are. So I cleaned it up and followed the instructions linked to by claptonman (thanks again
). It's now running at 4.4GHz with 1.32v and the temperature of the cores is averaging about 55C under full load with prime95. The fan isn't even at full speed
I might increase it to 4.5GHz and not bother going higher, as suggested by bigfella. Thanks again guys. Really, really happy now
