Maximum "safe" temp for OC'd Duron 650??

[spurdy]

The config...

ABIT KT7-RAID
Duron 650 @ 850 stable at 1.675v (VIA Hardware Monitor and BIOS report around 1.72v actual)
Current max temp under Prime95 Tourture Test : 37 degrees Centigrade (from VIA Hardware Monitor)

My question is this, what would y'all consider the maximum "safe" operating temp to be for overclocking a Duron? My gut sense is somewhere in the high 40s Centigrade from what I've read. I don't have a fancy HSF on the chip, but it is a solid one with a good fan and high fin density, aluminum, and I lapped the thing down to almost optical flatness. I'm using a generic thermal grease and the temps are currently reported as 37-38 degrees under load.

How much should I worry about the fact that the thermistor on the KT7 is underneath the CPU? It seems that because of that I should be guessing that the actual core is hotter than what is reported. If so, by how much would be reasonable?

I'd like to push this chip higher if possible (900+?), but I don't want to resort to exotic cooling, and I don't want to have to worry about frying the chip if the fan fails while I'm away (I'm not that much of a hardware fanatic, just want to stretch my bang for the buck).

Thanks much!

the chip will easy go up to 55oC so you don't need to worry mine is running @42oC
i have a duron 700@950

The readings can either be too low or too high, you can never "really" tell with Socket A mb's. As far as too high, i would try to keep the "reading temp" under 60, and you should be okay.

60 centigrade? Wow! I guess I've been pretty conservative in my estimates then. I thought for sure going up that high was risking permanent damage. In that case, I'll try bumping the voltage up a bit more and see if I can get a few more million cycles per second out of that $70 wonder...

Thanks Mikewarrior2!

well, remember that a) duron/t-bird cores are rated to 90C max core temp.

and b), if you have a newer bios, the readings should give you a fairly good &quot;approximation&quot; of cpu core peak temp. plus, t-birds at 1.2ghz + 1.8v are usually running into the high 50C range.
