My system ABIT AN7 HyperX PC3500 Audigy MP3+ ATI 9800 Pro AMD T-Bred 2100+ XP My HS/F: http://www.coolermaster.com/index.p...HAC-V81+X-DREAM My Problem: I can't get my system to run at 200 FSB. Current config (stable): 12 x 180 @ 1.75 All other voltage default Memory Timings 6-2-2-2 Load CPU temp: 101° F What I have tried 11 x 200 @ 1.8 Vdimm: 2.7/2.8/2.9 VNB: 1.70/1.75 Memory Timing 6-3-3-2 stable looping memtest 10 times 10 x 200 @ 1.75/1.8 Vdimm: 2.7/2.8/2.9 Vnb: 1.70/1.75 Timing 5-3-3-2 stable looping memtest 10 times 6-3-3-2 stable looping memtest 10 times With the above settings window would only make it to the splash screen. I then set everything back to default. Just messed with the CPU and set it to 13 x 196 @ 1.75 was able to boot into windows but I didn't like the CPU temp of 141° F. My question if my memory and mobo can handle 200 mhz fsb. In theory I should have to mess with the Northbridge, and DIMM voltage. Just the CPU. So am I safe to say its the CPU that doesn't like the 200 FSB?
