Re: Team Black Miner (Ethereum, Ethereum classic, Vertcoin, Zilliqa+dual 0.5% fee)

hi.
my 1st times trying tbm and it's going fine with a 6800xt. some issues tho:
- can't say if my stall ratio ok: 114/0/21 ?

TBMiner --algo ethash --hostname eu1.ethermine.org --port 5555 --wallet %ETH_WALLET% --worker-name TEST1amd --xintensity -1 --templimit 66 -b -d

Remove --xintensity -1 for this pool. Ethermine doesn't pay for stale shares, so you need a low value like the default --xintensity 24 or similar. --xintensity 78 was reported to run good on the 6800XT.

The hashrate will drop, but if you want to use --xintensity -1 switch to 2miners, f2pool, miningpoolhub, nanopool or similar.

I'm currently running between 800 and 1024 on my 6800's on 2Miners and getting decent results (66-68 MH/s). The funny thing is that my fastest and most stable card is my Sapphire 6800, the 6800XTs are close and run very nearly the same hashrate in the client but their share rate at the pool is lower, and by far my worst card is the 6900XT which won't run full memory speed without crashing (same memory as the 6800XTs) and constantly drops to low power if the memory is pushed too fast, or has these annoying 1 second power downs which don't crash the miner (as opposed to those glitches that do crash the miner and the driver).

But in general, it seems that I can push the intensities on these cards without getting _any_ stale shares at the pool, and maybe 20% 'estimated' by the miner.

Oh, and yeah, there are certain AMD cards that will not show statistics, but I'm not exactly sure why, since I have two ASUS TUF 6800XT cards that are identical, one shows stats and the other doesn't, (the other one that doesn't show stats, is unsurprisingly my 6900XT), while they all show stats in the HiveOS GUI.

I don´t think that you can push so high your intensity without getting stale shares. Can you show us your miner with stats? All over intensity 80 result in more staleshares - tested with 10 different AMD cards.
My Nvidia rigs runs fine with intensity 284.

I really only look at the pool stats for stale shares and I'll check through the miner logs to see if there were any stales or rejects that aren't represented in the pool data. I don't even look at the miner hashrate information anymore really, I'll calculate the average pool hashrate myself based on the number of valid shares submitted and the timeframe over which those shares are submitted (ensuring valid shares from the miner data = valid shares from the pool data). I've managed to push the miners hard enough to get stale shares at the pool, but once you go over a certain intensity, the miner becomes super unstable and generally getting stale shares is past the point of long term stability anyway.
