I told you the story of my ASUS P4C box. I found that at the stock
FSB speed, the RAM would run at 5-2-2-2 timings. At even a single MHz
faster, it would fail randomly during boot until I increased RAM
latency. Since I believe* that for my workload (the only things I
ever wait for are gcc and the Python interpreter), memory latency
matters more than raw CPU speed, I'm happy with that setup. It has
been very stable -- at this moment, it's been up for 46 days.
In the TiVo Engineering Snail Racing Series, I've just barely edged
out the second fastest box, a P4C 3.06 GHz with more normal RAM
timings. The benchmark is g++ compilation and linking.
Hardware:
ASUS P4P800 motherboard (Intel i865 "Springdale" chipset)
Pentium 4 2.4GHz (hyperthreaded, 800 MHz FSB)
ordinary Intel CPU cooler
Kingston PC3500 HyperX RAM, 4 x 512 Mb
various other bits

Very good! Is that 228 MHz FSB w/ 15+1/3 multiplier? I'd love to see
an lmbench memory latency graph from your box at that speed.

*"I believe" means I haven't tested it. (-:
