Update.... I have no clue... no stablity with GPU under load at stock settings or otherwise. So, start from scratch.

Flash BIOS
Restore Defaults
Reseat hardware
Reinstall OS & Drivers
Test
Upon Fail... stick cattle prod in box, then activate.

much apologies for all the lost WU's.

:(

Slicker did post a method of testing without trashing work units earlier in this thread:

Alternatively just scan through the computer stats for identical GPUs.

You can see the config data, processing times and quickly calculate whether they are processing multiple work units at the same time.

If they're getter results than you, send a PM and ask how they do it. They're likely to share and save you from wasting time killing your computer and having to start over again from scratch.

Hi Martin, Appreciate your advice. I may get to that in time. Prior to Flashing the BIOS I found an error, SMBIOS 0X01 P1-DIMMB1 Single Bit ECC Memory Error. Could be the error originated from the multiple system crashes, could be I have a bad memory module. Happens. I'm creating a Memtest86 bootable USB drive to check it out.

Regarding the GPU. It simply won't run any GPU tasks (Collatz, GPUGrid, Amicable...) with any of the three AMD drivers written specific for this card. Not at default settings, not tweaked. Runs just several minutes, screen corrupts, goes black and there's no getting it back. I had no such issues for the first week. Ran stable 24/7 at default settings but throttled constantly. Downclocking eliminated the throttling and it was stable at ~ 1400Mhz at 20 degrees below its thermal ceiling. Ran great for several days. I had my best day ever at 6,610,612 credits!

Something changed... bad hardware, software, settings... don't know.

So, reseated the hardware, no issues found. Flashed the BIOS so it's factory configured with minor but necessary adjustments. I'll run a full test of the memory modules and we'll see where we go from there.

Thanks, I appreciate you reaching out.

Hi folks. Just wondering if anyone has a good config for a EVGA GTX 960 2gig.
I tried the settings posted here for a GTX 980 but amd not getting anywhere near the seconds per task that as what you posted.

I am doing 1 WU at a time in about 31 minutes and using this at the moment:

verbose=0
kernels_per_reduction=48
threads=9
lut_size=17
sleep=0
cache_sieve=1
reduce_cpu=0
sieve_size=30

On a windows 10 machine with quad cpu no HT and 24 gig ram.

try:

verbose=1
kernels_per_reduction=48
threads=8
lut_size=16
sieve_size=30
cache_sieve=1
sleep=1

Any recomandation for my laptop?
CPU
Intel(R) Core(TM) i3 7130U CPU @ 2.70GHz [Family 6 Model 142 Stepping 9]

GPU
INTEL Intel(R) HD Graphics Kabylake ULT GT2 (1900MB) OpenCL: 2.0

Runtine now is about 20k sec .

thank you Martin. I will try that for a day or 2 and see :)

try:

verbose=1
kernels_per_reduction=48
threads=8
lut_size=16
sieve_size=30
cache_sieve=1
sleep=1

after only a few WU's it's already down to ~1100 per task. Thanks a bunch :)

From what I have read and understand, using an Intel GPU that is integrated to an Intel CPU (like almost all Intel powered laptops) is a waste of time.
You would get more benefit from running an additional CPU task.
You also use SHARED ram and CPU front side bus which takes away from your CPU tasks.

The decision, as always, is up to you.

Here is an example of what I read: https://setiathome.berkeley.edu/forum_thread.php?id=80356

Good luck :)

I take it this is the CPU config file? "collatz_sieve_1.40_windows_x86_64" Are there any optimizations for this like for the "collatz_sieve_1.30_windows_x86_64__opencl_nvidia_gpu" config file?

Yes and they go in the Nvidia file if you are using an Nvidia gpu, check out message #71 for the actual codes.The file should be blank if you aren't using any codes.

The Nvidia 980 states "verbose=0"

Is this a typo, or does your 980 go faster if it isn't verbose?

I have no idea what that means and haven't tried using a one instead.

The 980 config you posted says "verbose=0".

Was it a mistake or is there a reason to set verbose to 0?

I'd guess mistake, so maybe it should be corrected to 1?

It is a copy from the old website before Collatz switched to the current one, so no it wasn't a typo or mistake on my part.
I run 2 GTX980's and they are doing just fine with the zero.

My point was I have no clue what "verbose" even means in this context so a 1 or a zero wasn't tested by me any more than the settings for my GTX1080Ti gpu's were tested by me. Jon posted the original post and then people said changing this or that setting to this or that was faster so I copied the new settings and pasted them here.

"verbose" means that the config data is output in the Stderr output with each task -- so you can see the settings you've used and adjust if necessary.

So it's odd that the 980 config is set to 0 rather than 1.

Didn't know that.

Back up and running. Vega Frontier failed, took my MB out with it. The good, RMA replacement GPU, thank you AMD, the bad, new MB. So far, so good. No thermal issues or issues otherwise.

my pny 1080 ti had a fan crap out several months ago.been using a 120 mm fan on top of the card over the failed fan,been working just fine.was running about 160-165 degrees,little warm,but with in limits of the card.so today my replacement card i ordered got here,evga 1080ti sc2 hybrid.had a couple of minor glitches when i fired it up,but got them squared away.this card is way faster,like 20 secs per wu faster.they were running at 4minutes 10 or so,dropped them down to 3 minutes 45,give or take a few secs.biggest change though,is the temps,went from 163 on the other card to 113 on this one.personaly,think i would wait on those 2080s till they make a water cooled version myself.well thats my excitement for the day.

Smokin' fast! Nice!
