View Full Version : Ummmm... Your thoughts?

I got a couple of free PIII 666s yesterday. Since I'm banned from using the computer, I waited until no one was around to test them out. I soon learned that the board I was testing them on doesn't support an fsb of 133. Okay: Would it be safe to run them at this lower speed if I felt so inclined? And if I make a turbopll to boost the fsb to 133, will that be safe? Any other thoughts or suggestions? One more thing: I didn't use any thermal compound for the testing (mainly because I don't have much left and this is only testing). How much damage was done when my temps went too high to be displayed correctly? Just wondering.

It's always safe to run something slower than it's rated speed. It's ok not to use thermal paste during tests because the processor isn't really getting stressed too hard for a long period of time, plus thermal paste is to make sure you get the best efficiency out of the heat sink not an absolute.

P3/666s will run quite happily at 100MHz FSB, but you cant bring them up to their stock speed as the multiplier is locked.

That's a releif. But what about the matter of my temps going so high that they aren't displayed correctly? Maybe it's not a matter of them being too high?

I wasn't talking about changing the multiplier, I was talknig about changing the fsb via a turbopll. I'm pretty sure I can do that easily enough, but could someone do the math and find out what frequency the crystal will have to be? I think it's somewhere around 20mhz. I want to rig up a switch somewhere on the motherboard to switch from 100 to 133. That would be kinda cool. Thaks for listening to me ramble.
