Re: "As Yousef and Elmer have pointed out, most of Intel's Pentium II speed distribution is centered at the HIGH END of the spec - near 450 MHz." Face it Paul, the chip that Adrian bought was a remarked Xeon core that couldn't cut the mustard. If Inte's speed distribution was really at 450 MHz, why would they need a second variant/iteration of their .25u process to hit 450 (according to Yousef)? They clearly don't have this better process running at all their fabs. Kevin

Paul, RE:"A corollary is that it costs Intel very little extra money to make 450 MHz chips than it does 300 MHz chips." So what are Intels yields on 450s vs 300s? RE:"Next year when the 0.18 micron products are out, you will be able to overclock your 500 MHz Katmai to 700 MHz." Wow, all this coming from a guy who said "overclocking is a fools game"...I always knew you were a closet overclocker. Speaking of that, I'm receiving a lot of reports that CeleronAs made in Costa Rica don't overclock that well. Jim

Paul: The stock 0.35 micron PII-300 can never be overclocked to 450MHz. It uses BSRAM which cannot be run at 225MHz. The cartridge I have can run at 450MHz, and is multiplier-locked at 4.5x, The difference between the different speed grades of PIIs as well as Xeons lies within the L2 cache. The Deschutes core can easily achieve 450MHz, but the specially SRAM for the L2 cache is what makes it more expensive. This is also what is holding up the yield on the 450MHz Xeons. As for the hold Klamath core, it probably tops out below 400MHz. The beauty with the Mendocino as well as the K6-2 is, as long as the yield on the processor itself is high enough, you can clock it at a higher speed without increasing the cost. The bottom line: what I have is a 450MHz PII dressed up as a PII-300. it is not a failed Xeon or an overclocked 300MHz Klamath. Adrian
