[QUOTE=TheMawn;371683]From Friday May 16 to Monday May 26, I will be on another continent so my CPU and more importantly both GPUs will be down for 10 days @ 600 GHz-Days per day.[/QUOTE]

OK, thanks for the heads up.

Geezzz... Jerry has a power supply failure resulting in significant loss of cycles. Then LaurV loses two of his four cards due to another PSU failure (he was able to bring one back online using a spare (but smaller) unit), then people dare to take vacations!!! :wink:

I had hoped to be able to start going to 74 again at the end of the month, but now it looks like that won't be possible for a while longer.

The good news is we're slowly pulling ahead again going to 73 in the Cat4 range, and reclaiming the 1,588 candidates released at 72 a while ago as they expire. It's amazing just how much "churn" occurs up there, but as of the last couple of weeks no candidates are being assigned by Primenet for either LL'ing or P-1'ing at less than 73.

As always, if anyone has any spare GPU cycles, LL TF'ing would be much appreciated!!! :smile:

I should be able to bring my 580 online as of May 2nd, which should add another ~430GHd/d

Coolness! Thanks. Good news! :smile:

Soon I'll be able to move my GPU space heater out of the bedrooms and down into the basement. Then they can run round the clock again.

I must say the proved to be EXCELLENT room heaters over the winter.

:smile: BTW, did you ever get them controlled via a USB temperature sensor?

I got a cheap one from Amazon, but it proved unreliable. The professional sensors were too much $$. So I just used varying pre-defined duty cycles based on expected daily and overnight temperatures.

It's not the heat the (now dead) 580 put out (97C!!) but the noise :no::no:

Now running dual 660's (overclocked) - getting 375 days/day and ...silence :smile:

Hmm, so you're getting less out of dual 660's than a 580 with less sound and more power consumption.

EDIT: Is Kepler really more power efficient W/GHz? Hmm...

That doesn't sound right to me. Are you running two instances of mfactx? Or maybe you mean 375/card?

On my gtx480 + gtx580 I get 820 GHD/day in the 69M range with 2 instances of mfactc..

Sounds [url=http://www.mersenne.ca/mfaktc.php]right to me[/url].
GTX 660 (not Ti) at stock speed (no boost) should be about 179GHd/d, so two of them about 358, so 375 sounds about right.

For reference:
GTX 480 (368) + GTX 580 (433) = 801GHd/d at stock clocks (no boost)

When we ran our 660Ti it was good for ~275 a day.

With a bit of P-1 testing on the CPU we could just barely squeak by 2,000 a week.
