Hey Christian,

Updated Google sheet with my results after flashing the vBIOS of my dual 680Ms (SLI) (letting me to mess with the GPU Clock), and pushing the GPU Clock to +135MHz and the Memory Clock to +350MHz.

Now pulling 280kH/s from just under 2V which is GRAVY! AND even though I'm not in interactive mode, it's having cray little slow-down effect on my laptop.


One thing that I noticed is that with the OC settings in place, auto-tune acted all kinds of batshit when I was trying to tune both cards at once. Took upwards of an hour and debug output was out of sync and held no reality to the actual speeds I could pull.

So I just tuned one card at a time, that worked out fine.


Time to get desktop on it meow. Let us know how you go with that GT640 an if I buy one I'll totefully hit you with some LTC 4 the ref.

I dont know enough about mining to compare this for me, but how do you think our nvidia mining is stacking up against amd mining now? Are we at like 60%, or higher?


Be perfect!! =!= all my bests
