i'm also waitting for a optimized cpu minning tool, it seems that somebody has that version, now it's unfair for vs whice use the old tool~~
Why would you do that when mining with the existing miner is still very profitable? (And I would add does not risk wasting your time mining unspendable coins or other problems, as happened to people using another too-hastily-released mining tool.) Testing is good. Be patient.
I mined with 4x Core i7 3770 for four days straight and didn't find a block. doesn't seem profitable to me. was I just unlucky?
What was your hash rate? Here's the computation for my i7-4770, which gets roughly 25 hashes/sec (I'm not at it now):
blocks/day = (86400*hashes/sec) / diff
Diff *now* is really high, but yesterday it was around 16,000,000, so:
86400*25/16000000 = 0.135
Which means that it should find a block every 1/0.135 = 7.4 days. Your 3770s are probably similar, so with 4 of them, you should find a block every 2 days or so. You could have been unlucky or maybe I over-estimated the hash rate you were getting.
With diff at 35m, you'll get a block every 4 days. I'd probably move to a pool, because while you should be getting 4-5 MRO per day from your setup, it'll be very bursty.
