Congrats!

Just added an i7 920 to chase you down... Sniper

You folding -bigadv units Jason?

I did say "big" when asked - do I have to do anything else?

CPU folding seems so underwhelming. What are the big producers running? Mostly GPU?

Jason,
Core i7's in the 3+ Ghz range put up really good numbers with the -bigadv work units, but it requires a dedicated linux 64 installation. There is an experimental notfred vmware image, but again it pretty much takes a dedicated computer.

A 4Ghz Core i7 folding -bigadv work units averages about 30,000 ppd. I would guess a Core i7 running in the 3.5Ghz range would average about 25,000 ppd. These -bigadv work units take about 2 to 3 days to finish depending on the speed of the system. They were designed to be run by multi processor systems and need at least 8 cores. They weren't technically intended to be folded by the Core i7 cpu's, but the i7's hyperthreading gives it 8 logical processors and the high clock speed allow them to finish the work units within the bonus time frame.

For comparison, one i7 running at 4Ghz is just as fast as my dual quad core xeon 5520 system running both cpu's at 2.26Ghz with 16 logical processors. (8 actual and 8 hyperthreaded). It's probably several hundred $$$ cheaper too.

Wow! Something very wrong when I am getting @5000 points per day with my main desktop's HD5870 and two cores of a quad core Xeon folding while I am not working PLUS a dedicated i7 920 folding 24/7. It is in Windows 7, but nothing else is running on that system.

Bigadv set for all CPU folders.

I used the info and downloads from thegrub's post... Have it up and running, but saw a limit of 4 CPU cores on that VMWare install. Do I just run two instances? Or can I tell folding to use 8 cores anyway in one instance?
