Thank you guys for your answers, things are more clear now!

I have 2 gtx 970 for now and want to add 2 more gtx card for my coming x99-ud4gigabyte.

I don't want to invest a lot in both card so I was wondering if gtx660ti , 670 or 590 make good choice. 180$ for both card maximum.

I'm running mostly pss sieve, and few times genefer.

Hello,

We can see top GPU models for primedrid that gtx 560 is better than gtx 970, gtx 670 or gtx 660 and even better than the gtx 560ti...

Is it normal that old gpu's perform better?

Hi,

I would like to know if using the gpu on pci express 3 or 2.0 on 16X or 8X does make any difference on gpu time computing?

hi,

genefer works fine with sli setup but not pss, I would like to make a reminder about my previous problem and that is the pc freezes only when I cancel or pause the primegrid computing when using the pss sieve.

I agree with you that there are many factors that making the problem happen and which are deficult to diagnose.

Setting boinc to no new task didnt fix it but disabling sli seems to have fix the problem!

hi thanks for your answer,

the cards are not overclocked but there are 100% stable in all stress test,temps are all fine, max 65 degrees.

running pss stieve isn't a problem as i can run it for a whole continuous year without any issues. . My problem is just when a stop the pss stieve computing that my pc freezes.

other primegrid subprojects gpu are fine and are not making any freeze.

Hello,

I have figured out that when I log out and stop using my gpu which is computing the PSS Stieve subproject my screen freezes than an nvidia error driver message appears, sometime the screen goes black and I have to manually restart my pc.

When I cancel the PSS STIEVE and switch to Genefer 3.07 and opencl computing I have no issues. The computer is running fine and can stop the work whenever I want without any freeze.

All my sof and drivers are up to date, I'm using win8.1 64bit and sli gtx970.

Can anyone explain why this happening?

best regards
