Not too shabby I figure. :) Can't >wait for the AMD Hammer (x86-64)... Intel Pentium 4 (Northwood) 1800MHz overclocked to 2465MHz, 137fsb I see a couple of problems here. One the "Northwood" core AFAIK is 2.2Ghz before overclocking. You have it at 1.8Ghz? This appears to be the "Willamette" core on a 0.18 micron process. The other problem, is the bus 137Mhz, that is _slow_ and can't be using either DDR-SDRAM or RDRAM. If you use RDRAM at 400Mgh with a "Northwood" core at 2.2Ghz or faster then your results will be far higher for your Crafty Benchmark/P-4 test. Terry
