Title: poclbm and phoenix-1.3 no worksize better than -w64 and -w128 (5870,5970) Post by: marcus_of_augustus on April 30, 2011, 02:43:32 AM Okay, here's a tip for free for anybody using the Cypress chip (5870, 5970) ... it seems the new phoenix miner 1.3 goes a bit faster using worksize=64 now not worksize=128 ... and it is same on new poclbm also i think ...i.e., -w 64 is now better than -w 128 ... must be something to with the BFI_INT flag being enabled ... check it out (I waited until new difficulty is set to release this info but have been using this for a few days already).
... you can thank me later with tips ;) EDIT: after more testing as per discussion below NO worksize flag or setting (default) is better than -w64 and -w128 Title: Re: poclbm - w64 and phoenix-1.3 worksize=64 is better than 128 (5870,5970) Post by: TurdHurdur on April 30, 2011, 02:51:08 AM How does it do with no worksize setting?

Good question, it is better again ... 338~340 ... so going to edit title of thread. Can get rid of worksize flag ... less crap on CLI is good.
