I explicitly benched my miner against Claymore 9.7, and i also explicitly said i couldn't beat it, by an order of magnitude. It can push my HD7850 1G to 450, i cannot go above 370
but yes, i'm still second, other miners are still worse. But i found jce a lot more stable than Claymore 11.3 and faster on cards with 2G+ memory.
On RX550 and RX560 jce should be the best if configured properly, which include waiting for 5-10 minutes after each start to let it warm up.
On RX460 2G use multi-hash 416, 432, 448 or 464, worksize 8, alpha 4 or 8, beta 64. On 4G, use same and multi_hash 464.
Otherwise try the 0.31e, the most stable so far, it takes ages to compile its opencl but may mine a bit faster than 0.32 in some cases.
It's true. Clay 9.7 knows the secret but no longer works on new algorithms. So now JCE it's the number one miner for old GPU (HD6870 on Clay - 290Hs, JCE - 260Hs (effectiv 240).
{ "mode" : "GPU", "worksize" : 8, "alpha" : 64, "beta" : 8, "gamma" : 4, "delta" : 4, "epsilon" : 4, "zeta":4, "index" : 0, "multi_hash":368 },
On RX 460 4G new SRB1.6.6 after 5-10m give 463Hs on each GPU. JCE stuck on 420-440 depending on the card (like old srb 1.30)
I also had that the cards gave out only half of the maximum speed. Noticed once
