Thank you very much yvg1900 for releasing this publicly. I am getting a 3x increase and that is fantastic. I've got a question though. As I run your miner, my hashes will start at a certain number and then climb continuously until my system becomes unstable and my graphics cards drop out and I need to restart the computer. My CPU temps start out low and climb and climb as well.

My setup is a 4820k, overclocked to 4.5G Ivy Bridge. I'm running 5 threads atm after starting with 7 then crashing, and then 6 followed by eventual crashing. It appears as if 5 threads is going to do this as well as my hashes climb. I started at about 9.6 and now it's well above 9.9. My temps started in the high EDIT:60's (Not 70's) (c) and are now beginning to pass 80c.

Any idea what would cause this?

Sorry if anyone's asked this before, but I didn't see it mentioned anywhere in the thread.

EDIT: I found out that it's just maxing out the cooling capabilities of my heatsink. Looks like I'll have to get rid of the overclock or go to water cooling to feel comfortable running this at more than 4 threads, I've got a fairly capable heatsink on there. 5 threads is right on the limit - my fan is maxed out and the cpu rests at about 82-83c. Anything more than that it just gets too hot and leads to instability. It is interesting to see that I gain ~10% more hashes by pushing the cpu into higher temperatures.
