What's the highest hashing speed you've ever seen from one of your connected workers?
Anyone ever seen 500 MH/s?
I'm assuming at the moment the highest single worker would be a watercooled overvolted overclocked 5870?
Or am I totally wrong and everyone is using multiminer to converge all workers into a single external worker thread? Would this be more efficient?
If you mean a single card, my best is 441Mh/s as measured by 24-hour count of accepted hashes on BTCmine, from a Sapphire HD5870 clocked at 975MHz core, 325MHz memory, aircooled, standard voltage. The Sapphire cards are good in terms of performance for noise level - they have fairly quiet fans and I can tolerate one in the living room.
If you mean a single machine, my best is 1720Mh/s, measured by 24-hour accepted hashes, from 4 XFX HD5870s, all at 960MHz core, 320MHz memory, aircooled, standard voltage. This is my best in terms of performance for capital cost - XFX 5870s cost quite a lot less than Sapphire and give about 97.5% of the performance.
If you mean from a cluster... well, there are people out there who have _big_ clusters that make my 12 5870s look small and pathetic.
