When I was running PPS-Sv and AP-27 on a GTX 1660, according to HWMonitor the GPU usage was around 90 % and temperature 77-80 °C.

Now I switched to GFN-19 and saw that the GPU temperature was only around 55 °C and usage around 3-5 % (both according to HWMonitor). I could doubt the usage-%, but the temperature is low as well.

BOINC estimates 120 mins total time for the WU. Is this normal behavior and ETA for that card?


If it is of concern, the CPU is a i7-4790K which is currently working on WOO.

Stopping/restarting a few times apparently unstuck something, temperature is back at near 80 °C ;)

Unfortunately it's not working. When I suspend the task and restart it works for a short while and then progress stops. Same for GFN-17 (mega).

Apparently there's some problem, according to stderr.txt:

According to this post it happens when the GPU overheats. It's usually at 78-79 °C, rarely up to 80 °C. I'm surprised that already causes problems, it's a new card. But I'll try and use MSI Afterburner.


Update: I use Afterburner to reduce clock and core by 2 MHz and limited temperature to 75 °C. It never went above 68 °C but still the task failed. I have no idea by how much frequencies should be reduced, is 2 MHz very little? I still these problems are strange, is something wrong with the card?

If it's a new GPU, I'd return it to the store for a replacement or refund. Otherwise, I'd RMA it under warranty.

Unless you have reason to suspect some other part of the computer is defective, it sounds like this GPU is not working correctly.

Ok, I'll do that. I bought it only 10 days ago.
