Re: [JCE] Ultrafast CN-Heavy/Tube/HVX miner, low power, Vega56 1750+ h/s
I'm claiming to be the fastest on old GPU and I don't even provide a decent autoconfig for old cards, what a shame...
I'll update some autoconf for those cards like Cayman, Tahiti, Bonaire or Pitcairn.
Perf on HD6990:
https://github.com/jceminer/cn_gpu_miner/issues/26
This guy shared his config that goes to 270 h/s per GPU (HD6990 is a dual GPU) with no memory strip hack (which is lame, i will advise him to patch his BIOS).
It translates:
Thanks all for report and sharing your optimal config. Don't forget to tell what algo you're mining
so i can put those config in the Github doc.
Greeks above beta are deprecated, worksize is very like in XMRstak, multi_hash is like XMRstak intensity (but unlike SRB intensity) and alpha/beta are internal data packing parameters, no general rule, sometimes doing x2 or /2 on the defaults gives a little boost. Depends on the card and algo you mine. My autoconfig always defaults to 64 and 8.

Settings used : 32 worksize and 864 intensity.
I guess that's on one thread per GPU, the dual threading is for GCN cards.It translates:
Code:
{ "mode" : "GPU", "worksize" : 32, "alpha" : 64, "beta" : 8, "index" : ...., "multi_hash":864 }

Tuning is just a bit of a hobby of mine
I usualy get complains about the parameters being too numerous (there are four). Not to few.Greeks above beta are deprecated, worksize is very like in XMRstak, multi_hash is like XMRstak intensity (but unlike SRB intensity) and alpha/beta are internal data packing parameters, no general rule, sometimes doing x2 or /2 on the defaults gives a little boost.
