Well your XP isnt properly tweaked then

I can do a clock for clock comparison with reverendmaynard's best time on hwbot. He has 8m25.xxx s @ 4505Mhz in Windows 7

I will use XPSP3 or 2k3 maybe both if I have time

In other news ill beat it by at least 3 seconds same clocks/ram etc

And im not just making numbers up. Use performance product (PP) calculation to estimate your pi efficiency (cpu clock * pi time in seconds). You can then extrapolate/interpolate times at different clock speeds. The lower the PP the better your efficiency.

Im at work so I can only use examples from hwbot profiles. For instance in Reverend's run, 505.680 seconds * 4505 cpu = 2278088.4 PP

Versus my run 421.3 seconds * 5009 cpu = 2154768.7 PP

If you want to see my pi time at 4505 simply substitute... x * 4505 = 2154768.7. X=478.306 seconds. So I should theoretically be able to beat that score by a half minute or so. Now if I match my ram clocks to his that gap would of course close a little, but XP is still faster.

beat it by 20+ seconds at the same settings, timings and what not and I'll call hax lol.

What run? Im just browsing his hwbot profile and his 5070mhz @ 7m13.xxx = 2216319 PP

EDIT: I found it, if your talking about his 3200mhz LCC submission? Lower clocks is easier to achieve lower PP.
