I think CPDN is among the more demanding projects, RAM wise (200 MB last time I checked which is some time ago, tho). With an i7 quad core (so 8 threads) plus Windows Vista, you would probably like to have more than 2GB RAM to have enough headroom. If you have to use the swap file to satisfy memory needs of the apps, the superior RAM bandwidth of Nehalem won't help that much really.
My i7-920's up an running and has completed 16WUs (8 each with 6.04 and 6.05 for windows. I'm already drooling at the boost my RAC is going to get, with an estimated 4600/day at stock, and 7000 at a hoped for 4gig once i get my water block.
The h2o upgrade probably won't happen until after thanksgiving, and I'm not planning to switch it to my primary system until then, so with any luck I should be able to accumulate a large slug of clean data for ready reconer testing. I noticed that the runtimes in the WUs done so far were extremely flat, and am wondering if I'm just in a valley or if the high memory bandwidth of the Nehalem architecture is smoothing out the runtimes. IIRC Bernd(Bruce?) said the variable part was memory intensive.

I think it was the new Rosetta application (1.40) which sometimes demands up to 800 MB. I didn't check those facts though, I read it in the bug/whine thread about that application.

Impressive speedup with 6.05. I been off the windows-wagon for long time so i got to ask, is the 6.05 speedup that big also for Core2? And AMD?
No overclock yet? I'm at 3.5 on both core and uncore now, at this overclock memory timings became a problem so it didnt look much faster. Dont trust Bios, these are very new boards and very immature bios'. On this EX58-UD5 Bios said 9-9-9-24 at 1750MHz but it was actually 10-11-11-thirtysomething. I think i got it down to 10-9-9-26 now so should see some improvement, i hope. Still loose though, more work is needed.
nope. I don't want to waste time messing around with the stock cooler and the only waterblocks available (Thermaltake and Koolance) were both 2nd tier in their s775 editions. Swiftech's alledgedly going to have a GTZ adaptor out this week. Once I get it, I'll do the OC test cycle.

... IF you can resist the urge :D
Stock cooler isnt much to write poems about but also not all terrible, if your 920 is similar to mine you should reach 3.5 at less than 1.25v core, 1.36-1.40v uncore, any crap aircooler can handle those voltages.

Valley.
For your frequency, the predicted cycle length is 191, so the twin peaks surrounding your data should be at 382 and 573.
Your reported results so far are from between 473 and 490, so really, really far from the steep parts, and very near the predicted (broad, flat) valley bottom near 477. Sadly this means Ready Reckoner won't be able to get a useful fit to your data.
Pity, it would be nice to see the cycle.
As with my new Q9550, this situation with regard to your initial workload means your RAC competitiveness will be overstated, initially.
