Hmm ... does the GPU need to do graphics in parallel? If you are on Windows can you check if the system reports memory being flagged as "shared"?
Like e.g. here:
https://i.ibb.co/XV9H99t/win-shared-mem.jpg

In case that "Shared GPU memory" is greater then 0 the card copies part of the memory to host system (because something is occupying memory) and that causes the miner to get slow.
Have no real solution for this atm... maybe should add a flag that can force the card to step down one more solver (falling to 3G solver in this case ) .... hmmn

What driver version? Some drivers take more vmem on 1st GPU with monitor connected.
Try 20.4.2 driver. Before installing delete current with DDU.

NO SETTING, NO WORKIE--

When Claymore gets around to it, he may update the miner again.  He promised no further fees.

Take some time to read a page or so, he has been quoted just a few posts back.  Oh, and TeamRedMiner works on ethOS, but you will need to update it on your own.  And, ethOS will not read the hashrate properly for statistics.   With "show miner" you will get accurate console output.  

Plus, TeamRedMiner has a 2.5% fee.  My Vegas get 2kH/s each, without jumping through hoops, and I gained 700+ H/s each.       --scryptr

Claymore doesn't support Heavy algo.

"cryptonight_type" : "heavy",

If you have paid a minimum amount of focus while going through this thread you would have noticed that we stated that the whitepaper was done by the old team and we are working on another one more detailed and more technical.
But you were in a rush to come up with your amazing conclusion, Sherlock.

P.S: "show me sustainable" "to change your opinion" lol, you think way too highly of yourself. give it a rest and We don't care about your opinion.
If you don't want to invest in this coin that's fine by us, we didn't ask you to in the first place.  

diff is based on last 1440 blocks time. it will be reduced later.

Hashrate on network is calculated with:
Diff / Target time (60)

Thanks!
I did not notice this field and probably posted without it. Apparently this is the reason. At the moment, the purse status on Cryptopia is "Maintenance". I think there will be an update, but in my updated wallet the balance is 0, after importing * .wallet. Apparently my XLC is not destined to go to the stock exchange.

A ticket with cryptos is open. I'm waiting for the help from the developers, can they check this transaction in the current network and give the answer "We checked, the transaction exists, the problem from the Cryptopia". but do not send me immediately to create a ticket. You are worse than the Russian police!
