Repeat the idea of v2 and create new memory channels. The memory bandwidth can be greatly improved using more smaller DRAM partitions and parallel memory controllers with address interleaving. Other operations look good. Also, each VLIW instruction cost one cycle three for division. I tried "Precise", which usually works. Get an ad-free experience with special benefits, and directly support Reddit.
They are not much more efficient. So I think if you were somehow able to get it to pass just Claymore, that would be adequate. Why use NiceHash to sell your hashing power? Also, each VLIW instruction cost one cycle three for division. It depends either on block height or previous block hash TBD. Looks like connection issue That's why RandomX uses a lot of floating point math. Price graphs for numerous coins. The only difference from CNv2 is integer math part - it's random generated now, just like in ProgPoW. This is happening to me too, but I think it has to do with you using the pc along cryptonight, I'm assuming you are using cpu mining. Updated readme. If our chip had gone to production, and we had redone layouts to keep up with v2, I would be giggling about this tweak.
