Thanks for the update, Micro, was wondering what was up and am glad it's just machines, not backs.
I've been through that bit with the a_4 core, I presume, and I know this isn't your first episode either. If it's in fact the a_4 running one thread (one core) then it's electing to treat your machine as a single processor, that's what happened here. When you first went through this, we got you the 6.30 version which at that time got you a_3's instead of a_4's. Now very recently they've got new WU's which they're kind of forcing through and which require a_4. To run them however, you now need 6.34 which will then identify your machine properly and and d/l the LATEST a_4 which the new WU's require to run. Otherwise you sit there churning one core at 250 ppd. This at least is what happened here very recently on two and I think maybe three machines. The short answer for me was trash queue.dat, /work dir, core a_4, let it d/l a new w/u, do its thing, get itself the latest a_4 which then happily runs all 4 cores, and I don't know if you know this, it doesn't show until final points are rewarded, gives you a 10% bonus for all this folly.

I was right where you're at, ready to shut down the cpu side, but this worked. v7 btw fixes it too, but I like things slow and painful, lol.

Good going on the gpu fix.

guys,

Just wanted you to know I have turned off ALL SMP folding as I am getting a rash of wu's for 240 PPD taking entire days to run.

For the strain on my systems, 240 ppd is not worth it to me.

I did manage to get the GTX 460 to actually run two work units in a row last night. Wow!!!

I bumped the voltage to 1.025 I also have the computer attached to an APC ups so the current is consistent. This seems to be taking care of the "unstable GPU" and SHAKE errors I was getting. So, we'll see how that goes. I am monitoring it.

I figured 3 GPU's folding away was better than two.

That's where I am at.

the best,

micro...
