GPU to 72 status...

Honestly, I think taking part in any distributed project probably shortens the life of your PC at least a tiny bit (but maybe not).

But as long as everything is adequately cooled, it probably doesn't shorten it all that much. I would try it out and take a look at your temps. Anything over 80 is probably alarming (though I prefer all mine under 70).

So yes, I'll see you there at 500.

I'm aiming for year end....

yes, of course...that's what most of us do....

And, as long as the heat is managed, your computer's life won't change much...it will probably be replaced by upgrade before it dies....

CPU-Z and GPU-Z are your friends on Windows, sensors on Linux....

Hehe. My 2600k stock heatsink running at 3.5 GHz (3.4 stock) is running about 80C. That's why I've been asking so much about the Hyper 212+ :P

The only thing I've found that works was something like GKrellM, and that didn't pick up my 2600k when I installed it... (although my Linux has been down for a few months.)

Wow, you only have a slight overclock over stock and you're at 80C? Yeah perhaps an upgrade to your heatsink would be wise. Seems anything better than the stock heatsink would provide much better cooling. As a comparison, I have a 2500K at 4.5 GHz at 60C using an H80 at lowest fan speeds.

And I have my 2500k at 4.3 GHz at around 60C using a hyper 212.

The stock intel heat sinks are a joke. They finally removed them completely from the 3930 and 3960.

Okay. Well I will definitely consider adding my GPU to the effort. Will this also slow down the LL testing?

Not sure how your quad compares to mine (Intel Core2 Quad Q8200 @ 2.33GHz), but mine runs 'faster' with the GPU running. To explain a bit, the Core 2 Quad seems to share something between core 'pairs' that slows them down depending on the work being done. I started off using P95 with 4 LL's running, and all 4 had around 90ms per iteration. I found out if I switched core 2 and 4 to TF that the LL's now were at around 60ms per. So, using batch files and the start command to run mfaktc on cores 2 and 4 while setting P95 to 1 and 3 keeps the LL's around 60ms. My other GPU machines are i5's and I see a slight change with mfaktc running (2-4ms slower).

Mine is an i7 Q720 1.6 Ghz.

I'd reccommend doing like I did then, set P95 to use core 1 and 3 and set up mfaktc/o to run on core 2 and 4. Doing this you will see a significant speed up in your LL processing per core if you currently have all 4 cores doing LL. 2 core = 6 exp in the same time 4 core = 8 exp with this setup.

No worries. Thread hijacking is part of the thrill. It happens all the time.
