the nosync refers to the command __syncthreads() which should be used when initializing the shared memory. However in some case (and some card) it isn't really needed and as it tends to slow down the kernel and removing it may increase the hashrate. however on some card it may cause some cpu validation issues.
i notice sir. already try it and it does give about 10 kH/s more than standard cuda65 version but yes it also give many cpu validation in my card.
i think i will stick with cuda 65 default version.
i sincerely thank you for your work and all the donator that make this happen
PS:
sorry i can't afford any donation, i'm doing this as a new hobby to run from the stress of my daily work for the past 8 weeks, i mine only about 4-5 hours and not every day, and only get about 0.001xxx BTC once a week on nicehash. purely to make me feel i can achieve something... even for that small amount.
