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.
