Okay, switched off and back to three for me too. Be interesting to see if I can hold up at this rate.

So much for that idea. Noticed my internet slowing then heard my fans slowing down. Checked SETI and saw the to completion time rising instead of falling. Checked EVGA Precision and saw my temp and fan speed was down but it did not downclock. I went ahead and shut down the SETI Client and BM, switched back to two at a time and things are running smoothly again. This poor little GTS 450 1GB just can't handle three at a time.

One more little note, I did not shut down Firefox. I just made my changes to SETI and started it back up. Firefox is running better now too.

Oh! The penny has dropped. I've seen a VRAM utilisation blowout here & 3 tasks seems to be using way too much. Over 1.4GiG VRAM used

That was unintentional & likely you'll be able to go back to 3 once I figure out what has happened there (& fix it). No way should we be using that much per task, and indeed a 1 Gig card won't accomodate 3 strangely greedy instances.

While it ran, it ran good. I was only losing about a minute and a half over two at a time by running three. That's running shorties, I'm in the middle of the shorty storm right now. It would really be great if you find the problem and get us going again.

Oh I'll find it alright

There's some V7 issues to resolve as well, but I am a stickler for trying to shrink memory footprints, simply because I prefer computation over RAM. RAM's Slow

The chances of this weird build running on 256MiB cards is currently zero

Here's what happened when I tried to run 3 at a time

Try this one with 3 tasks, perryjay & ghost ( x39e attached, reduced footprint back to roughly normal, I hope)

thats got it

now able to run 3 tasks at a time with memory usage now @ 801MB which is the same as x39d was running 2 tasks

Sweet. Note to self: Lack of beer induces ID: 10t errors

arkayn · « **Reply #84 on:** 28 Jun 2011, 07:00:23 pm »

I just checked my 460 and it showed that I had used up to 740 MB and is at 710 MB right now with 2 at a time.

Changing over to x39e now.

[edit]Looks like it is down to 516 MB now[/edit]

perryjay · « **Reply #85 on:** 28 Jun 2011, 07:11:32 pm »

I'm here. Memory usuage-826MB, GPU Usage- 94-99%, temp ~ 69degrees. Fan sounds quieter but running at 70%. We'll see how it goes.

Okay, after just a few minutes little has changed. Temp has gone up to 72 degrees, and memory usage has gone down to 817MB. GPU usage has gone to 92 to 97%, staying right around 95% mostly. Here's hoping.

Slavac · « **Reply #86 on:** 29 Jun 2011, 01:36:57 am »

Checking in. Looks like I was a touch too late to snag the latest x39 build for testing.

Hoping this helps a bit, my 560ti's have been giving me fits.

Jason G · « **Reply #87 on:** 29 Jun 2011, 02:30:24 am »

Not too late. Have just been purposely burying test builds in this thread to limit distribution while still getting some wider testing. Will PM you link to newest (x39e) on Seti Main, to the post a few back. [Done, relayed that x39e should be more helpful in isolating any further problem at least, so fingers crossed it shows something obvious]

_heinz · « **Reply #88 on:** 29 Jun 2011, 03:27:58 am »

Hi Jason,
took x39e now for seti main on my GT540M (1GB), but get no work till now.
As soon as I have work, i will post again.

Jason G · « **Reply #89 on:** 29 Jun 2011, 03:31:18 am »

Cheers Heinz. If your error pops up as before then that'll be good for further diagnosis. If it doesn't well that'll be good too.
