Greasing up :p

[sassora]

Hey,

I received a second hand cpu from ebay this morning. I've put it on using the grease that was used with the old cpu.

I have upgraded to AMD Athlon 64 4000+ from AMD Athlon 64 3500+.

Firstly, is it important to replace the grease?
Secondly, after a while of using my pc, the computer froze on two separate occasions. Could using the old grease cause this? Maybe the chip overheated?

Thanks for your help

Using my old student card I got rid of the stuff on the cpu and left the stuff on the heat sink as it was.

Clear CMOS and them run a few hours of prime, on priority 9 while monitoring your temps, what cooler do you have?

On the fan it says asaka

Other than temperature could there be anything else wrong with the cpu that would cause the pc to freeze?

I must say that this is probably one of the most pointless upgrades i have ever heard of. All that hassle for an extra 200mhz and 512kb L2 cache. I also would never use old thermal grease. Better to apply some fresh stuff.

It was cheap and I enjoyed getting my hands dirty. It's the equivalent of enjoying some pasties even when you're not that hungry

I have now repasted it and the problem remains.

After the pc froze, I tried to restart it straight away and it didn't get past the BIOS. I'm thinking that the reason could be because it was still too hot.

If it is, then I don't see why. You tell me the upgrade is insignificant then surely the cooling system I had before should be alright.

Could there be any other reason for freezing?

All this talk of pasties is making me hungry!

Hey,

I cleared the CMOS and this seems to have done the trick! The temperatures have dropped by about 15C!

Thanks to Defcon5 for suggesting that.
