This is my first attempt at mining. I am attempting to run poclbm-mod on 2 GPUs hooked into a local bitcoind.exe instance. Is it normal for every getwork to become invalid/stale for such a small amount of Mhash? Output below.
As you can see, my efficiency is a whopping 0% with 268 of 275 getworks stale or invalid. 111 resulted in no answer. Is this expected or am I wasting my time?
Thanks!
