A bit of a puzzle about mining on xtl.cryptopool.space, may not be specific to the pool, but I've an 'R9 270x 2GB' and an 'RX 470 4GB' mining on xtl.cryptopool.space and the R9 270x gets about same shares as the RX 470, I thought the RX 470 would get lots more shares, what's going on ?
The answer is in your question, that's what's going on:
(each card running on a separate copy of Claymore)
You didn't specify static difficulty for each miner, so it's the pool that adjusts diff automatically for you, based on your workers' hashrate. Each pool is configured to adjust the diff on the fly to maintain some specific sharerate (set by the pool's operator), so that someone mining with a low-end CPU wouldn't be submitting 1 share per hour, and someone with a huge farm wouldn't be spamming the pool with dozens of shares each second.
OK, thanks. I never played around with the difficulty, always let be at default settings, but will play around this time and see what happens.
I see on for Claymore SSL on 'XTL.CryptoPool.Space' it uses 20000 and on 'communitypool.stellite.cash' it's 100000, will start test at 50000 on 'communitypool.stellite.cash' and see if I notice any difference.
