Switched to Linux, PPD up 30k+! stabilized now @205k ppd with 6901!

Nice! I am going to install it on one my rigs today. Got to give it a shot! Had to reduce my output from what I had last summer to only 2 rigs. But I will bring 1 of my my Q6600's out and let it crunch! 🙂
 
So the Linux WUs are better than Win again?

Will VMWare and whatever it was we used a year ago work now?
 
Finally had an error in Windows, so bumped voltage a bit & back to Linux. TPF is 9:39 with 6901 for 205k ppd!

I couldn't go any higher than 4.4 GHz (failed mprime tests)

Very nice! :thumbsup:
 
my first p6901 WU finished fine and received bonus (my first bigadv WU!🙂)

My second WU is a p2684. I had to reduce my clock speed to 4.3 GHz and also restarted with smp 8 -bigadv to "force" to use all 8 "cores". It was running a few steps with only 7 cores. 😵

Anyway the step time is 33:51 and ppd is 30,846. Kind of disappointing since I had a regular SMP getting 33K ppd. As usual, with F@H, it all depends on the WUs I guess.

Yeah, the 2684 is a much slower WU than the other bigadv. I'm only getting about 111k with those.

Are you sure that was folding regular SMP's? The highest I think I've ever gotten on SMP's was around 15k ppd on Windows...or is that the difference with folding on Linux? (Currently on an OC'd 1090T)

Curious as to what kind of power your SB system is drawing?

Either way, congrats on the ppd! I think I've been convinced to load up linux and give it a whirl.

Yeah, that was a regular SMP WU. I have a 1090T which is not crunching F@H but it was getting from 15-21 ppd in linux during the Holiday race. That's a dual boot system so I tested both windows and linux and linux was about 15% better at that time. I'm not sure about the new linux client. Might be a bit better. The big difference is the SB chip. It's seems much better than the 1090T on F@H SMP although I should do a direct comparison with the same client.

So my last two questions (for now) are,
1) What is the energy consumption (if you have something to measure it with) of your SB system...I'm looking to get a baseline here (for anyone else that wants to jump in) of just the 2600k folding with no gpu folding.

2) Are there differences between a virtual linux install and the full meal deal on a separate partition/drive as far as ppd?
