Its posible work with one GTX 650 ti?

Thanks

Yeah, that should work.

See here:

Specifically:

GPUGrid is now CC3.0 or higher

...
Still work (GeForce 600 series):
...
Mid-Range ... GTX 650Ti
...

With two GTX 650Ti and two GTX660 Ti GPUs I have contributed to GPUGrid since February 2013. I regret that I can no longer contribute as all work fails on these cards. I don't have the expertise to resolve the problem and can no longer lift the PCs to take them to a friend for review/repair.

You're running 343 and 353 drivers. I think you just need to upgrade to a recent driver to get CUDA 8 support.

Your failed workunits have

# The simulation has become unstable. Terminating to avoid lock-up (1)

error messages, while your 4 year old cards reach 70-77°C.
You should:
- clean the cooling fins with high pressure compressed air
- reduce the clock speed (or the power target) on these cards by a GPU utility (like MSI afterburner)
- perhaps it's a good idea to upgrade the driver from NVidia homepage (exit from BOINC manager with stopping scientific applications first)
If these steps won't help, then perhaps your cards have reached the end of their lifetime.

You should be able to run GPUGRIG WUs.

Having started with a 530, a few years ago I upgraded to a 640. (Please note that I am NOT a gamer, not at all.) I can run WUs OK, but it takes 2.3 to 8.8 times as long (times the averages given in the Performance page) on the 640.
If short runs are available, I tend to run those. However, even when only long run WUs are being generated, my 'lil 640 is chunking along OK. (Note that I keep my PC running 24/7.)
I had of late been giving MUCH thought to upgrading again. However, I am not going to invest in an external power supply. So, I'm rather limited to 750s or 1050s by power constraints. For now, I am not interested in spending $150 or so for such an upgrade**, when the 640 is still running fine.

In fact, in early March (2017) I DID buy a 750Ti, over Ebay. (not used, not reconditioned... straight from a factory in China) BIG mistake. While the price was 'good' ($77), I was taken badly. After having installed it (and I had to buy a different power connector), I realized (TechPowerUp GPU-Z as well as Nvidia GeForce Experience) that I had been 'sold a bill of goods.' Although NVidia and GeForce where written all over the unit, and the logos everywhere, the GPU was, essentially, junk. It only had 192 cores, while the NVidia specs are for 640. Well, as my existing GT 640 had 384 cores, I put that thing back in.
It took some two dozen rounds of emails, threats about reporting these Ebay con-artists to NVidia, etc. etc, but luckily I was finally able to get my money back.

** PS, I work from home several days a week, and having dual monitors is important for my productivity. Neither of my monitors has a DHMI input, so I am also limited in my choice of GPU models in this regard as well.
