Get a P4 motherboard that supportes DDR333 (PC2700). Then buy the Extreme PC2700 memory from www.corsair.com. It has a significant performance-enhancing feature: 2.0 cycle latency versus the more standard 2.5. This high-performance Corsair memory only costs a few bucks more than standard PC2700

Personally, I just ordered a brand spankin' new Compaq server (ugh... HP server now) with dual P4 Xeon 2.8 GHZ processors, 3GB of RAM. I can't wait to get my hot little hands on that and see just how well it crunches the #'s. It's memory is 200MHz DDR (FSB is 400MHz), advanced ECC (Compaq's

From: John R Pierce [mailto:[EMAIL PROTECTED]] the fastest P4 cpus have a rated FSB of 533 (which is 266*2). running the bus at 333(666) would be overclocking. No, it wouldn't. I don't think you understand how the memory architecture of a modern Intel chipset works. The memory clock speed

the fastest P4 cpus have a rated FSB of 533 (which is 266*2). running the bus at 333(666) would be overclocking. Ah, but most modern mobos can run the memory asynchronously to the processor bus. I think this goes back some way - certainly the Abit KT7A board (Athlon) could run the

From: John R Pierce [mailto:[EMAIL PROTECTED]] ok, true. I forgot VIA is allowing this. AFAIK, the i845pe doesn't support memory faster than the CPU FSB (it allows SLOWER memory, the older i845e only supported 100/200Mhz DDR w/a 133/266/533 CPU bus). Look again... the 845PE and 845GE
