Re: CGMINER GPU bitforce overclock monitor fanspeed GCN RPC linux/windows/osx 2.2.6
Hmm what do the 58xx report their name as? Cypress? It sounds like cgminer should default them to worksize 256 instead of 128. Would that be a fair assessment?
Yeah, it's Cypress.
The best worksize really depends on the user correctly setting the ram clock; on the default (1GHz), it's best 64 or 128 with 4 vectors.
V2-W128 is the "safe" bet, since it's almost constant through ram speeds.
V2-W256 is always better than V2-W128 for ram speeds <~425MHz, because even on dips (bad gpu/mem ratio) it's always faster.
