Claymore,
do you have any ideas how to overcome Polaris hashrate drop for epoch >129 ?

Genoil said that DAG now took 100% of first memory bank (2gb) and go to second memory bank, so access two banks instead of one leads significant hashrate drop.

Do you make any research in this direction, or it is hopeless? What you think, any comments?

I have this probleme with 8g rx 480 hash drop every new dag epoche on ethereum and ethereum classic

Minergate miner say with her laste version we do not loss effective Hashrate see here;

https://minergate.com/blog/v-6-5-no-hashrate-drop-after-dag-epoch-switch/

From the description I understood that now they generate DAG on GPU too. So it is not related to this issue.

I see the speed drop. I checked possible workarounds, at least for Polaris, they failed. So probably this hashrate drop cannot be fixed, at least on miner software level.

Well it can and it is fixed, but maybe you cant fix it. I think its time for competitive miner to be released...

If claymore can't fix it, chances are nobody can. Its hardware related. People with 280x suffered this also and they just mine ZEC now or bought RX series.

Since claymore,genoil couldn't find a solution with the 280x, chances are there is nothing that can be done.

My 6 year old Radeon 6990, never suffered from this problem and that card was crazy old.

The 2 GB problem can be solved with a certain memory management scheme. Level of effort may not be worth it, but Claymore can PM me to discuss.
