Hi all, I started mining a while ago with my 2 nvidia 670's and CUDAminer, and i used to be able to pull over 500000 ifc/day. I stopped mining for about a week and have now come back, and am only getting ~80k ifc/day. Is this just the difficulty increasing, or is there a problem with my miner? I'm getting ~300kh/s and am mining on ifc.scryptmining.com. Thanks for any help!
