amphoria, nice prime, congratulations!

Our first megabit prime from team search!

VBCurtis · 2006-10-01, 23:45

I built a Conroe system, and it produced a prime in its 2nd day:
3803443215*2^491104-1 is prime.
I double-checked on my P4 just in case.

For those curious, a stock E6300 Core2Duo LLRs at about P4-3400 speed, and sieves at roughly Sempron-3400 speed (with DDR400). These estimates were run simultaneously- one LLR thread, one NewPgen, assigned to different cores.

you should be able to achieve at least 2.1 or 2.33 GHz, by simple increase in FSB frequency

This would give you additional 16-30% performance for "free"

Cruelty-- if I don't get 3.0Ghz, I'll be disappointed. But that has to wait for a new board; current board only has FSB up to 300, so I'm at 2.1Ghz at present. CPU temp 46C with both cores 100% load, with a Zalman 9500 cooler (fan throttling for silence).
