if your card sounds like a jet engine then you should probably run Qubit, it uses less electricity and isn't as taxing on the card as skein. I ran skein for awhile but converted to qubit once I got my kill-a-watt out.
Yea I was runnin Qubit over night, altho the P/O's are smaller & more frequent.. if The Dev Pool hits a Skein Block.. I score better than Qubit mining for an entire day. Helps warm the drafty room too.. heh
Im not sure why either, as I have payed pretty close attention, but even tho The Blocks Factory has a 'lower pool fee' The dev pool pays better on averages, by a significant ammount over time.
I have no idea what a -g2 option is.. I run config files in CGwatcher, not Batch files.
Heres my Skein Settings:
the -g 2 option is the same as gpu-threads in your config.
From what I remember your config looks pretty good. I would note that your engine clock is at 1150. Turn that down, at least in my experience, I wasn't ever able to maintain a stable clock that high. Ive mined at 1150 before but I couldn't keep it stable for more than a day without crashing.
Also, you probably want to add a "auto-gpu" : true, to that as well. This will help control your fans better. What are your temps with that config?
I am not sure you want "gpu-fan" : "0-0" either, that could be setting your fans at 100% im not sure. I set mine at 20-80 I think.
Try that out and let me know how it goes.
