Anyone else have their 750ti cards hashing at different speeds with each restart of the miner? sometimes it mines at 800kh per card, sometimes 200-2400, sometimes 2400 and occasionally 3050-3100kh/s per card. I've just been restarting the miner until it settles on the higher hashrate, but is there a simpler way? on a related note, when it comes up with the lower end hash speed the entire system laaaaags right down to a crawl until I manage to kill the process (win 8.1)


edit: im also getting errors occasionally. sometimes right after launch sometimes after mining for 15-20 minutes. It's not always the same but heres one I was able to catch before the miner closed itself.
