P!!!-550 at 682Mhz Review
Posted: Sept 9, 1999 Dang, I'm tired. Let me tell you, benchmarking blows hot salty chunks. You can quote me on that. "But mom, Apex says benchmarking blows hot salty chunks..." Hmm, maybe you better not. This is the first part of a 2 part article on the effects of overclocking. Man, I sound like a PBS special. We're going to delve into this topic a little backwards from the way you'll see most overclocking articles written. This first part will deal with the speed gains due to overclocking. The second article will deal with how I got an Intel Pentium III 550 to 682mhz using reasonably conventional cooling. Let me start by saying that Pentium III 550's are reasonably good overclockers. Anyone who tells you otherwise is probably smoking too much of the good stuff. I've only had an opportunity to play with 3 of them, two retail and one preproduction unlocked one. The poorest quality one did 644mhz at 2.1 volts quite stably. The unlocked one did 650mhz at 2.1 volts. The good one, the one reviewed here, does 682mhz at 2.2 volts with the proper cooling. With active cooling, nah, I'll speculate on that on the next article. OK, on to the setup... The Test Rig
For the test rig, all the settings are optimized for speed, not stability. It's stable anyways. Here's a pict:
