GPU mining only sitting on 19 C
Well that's not right at all... typo, or is that what it's actually saying?
Maybe we have some confusion there - I was referring to the CPU temp while running GPU mining. The actual GPU's are running much hotter - atm one runs at 85ish and the other at 67ish - I will be adding another fan to help the hotter card.
85'C is a little hot IMHO. What gets me though is that you said in your OP that it only shuts down once you've started the Litecoin mining. What program are you using? Try using the newest version of Cgminer if you already aren't. You might have something improperly configured.
It's true that it was shutting down when I used the litecoin miner, but after making my original post it ran successfully on litecoin for 45 minutes, and so I tried adding the primecoin miner and it crashed. I have since restarted litecoin and it has now been running 2 1/2 hours. But I figure if I start primecoin it will crash again. I plan to let it (litecoin) run overnight to see what happens.
I am using cgminer 3.3.1.
I am adding on a new fan for that hot card tomorrow so hope to see that problem rectified.
Here's my litecoin bat file:
cgminer.exe --scrypt -o stratum+tcp//ltc-stratum.kattare.com:3333 -u xxx -p xxx --intensity 13 -g 2 --thread-concurrency 8192 --lookup-gap 2 --gpu-powertune 20 --gpu-fan 65 --auto-gpu --no-submit-stale
