PIII 600 Overheating Problems :(

[gizmo1_1]

Have any of you had any problems with the PIII 600 ? I've had to RMA 3 of the 9 I ordered this week. It seems they are generating heat of 240-260 F at boot. I tried everything I knew of to make them run cooler, bigger heatsink and fan, two fans, even under clocking the system to 66Mhz bus.
I Use ASUS P3BF motherboards in jumper mode.
I know it's not the board that I'm using because I tried known good PIII 600 Processors and the run cool. I don't know but I believe I just recieved a bad batch of Processors. Any of you had the similar problems?

Hi.
I've had a similar problem, when used a PIII 550, twice. The CPU needed an extra fan. When I checked it without it, the system went "crazy"...
Heat problem became a fact, nowadays!

Good luck...

I have had similar problems. When you check the heatsink after the machine has been running a while it is usually not very warm and the cpu temp monitor is showing temps over 100c. remove the heatsink and scrape off the heat transfer pad on the back of the heatsink and dab a bit of heatsink goo on it (silicon heatsink compound-same stuff used on socket 7). This provides much better thermal transfers than the pad.

Which version of PIII processors are having this problem? The oem version or the retail box version?

As far as I was aware there is no difference between oem and retail except for the price and the lack of extra packing.

apart from the OEM ones do not have the pathetic little heatsink & fan that the retail ones have http://www.windrivers.com/cgi-bin/forum/smile.gif and the price of the retail one is usually £ 15 -20 more expensive.

Some of the older chihps used slightly better cache chips in the Retail ones than the OEM, and also the Retail chips have a 3 year warranty rather than the 12 months on an OEM chip.

I had the same problem PIII600 and it was the same as the above recommended. Before I was hitting 240f and above with lock-ups and registry errors. After I scraped off the worthless so called heatsink "Pad" and put thermal grease on, it started working fine. No lock-ups whatsoever and running at 130f. With RAIN it cooled it down to 100f. This one really fooled me. I thought it was the memory, motherboard, windows. Almost seemed to simple when fixed!
