hashrate decrease on all coin with algo Ethash

[lemao]

Hi guys,

since few weeks my hashrate decrease on algo Ethash with claymore version 11.9 and before. I don't understand what happens

I use GTx 1060 6GB.

On Equihash algo value are always good.

I tried different driver and the result is the same.

Someone has an idea ? because I don't understand.

Thank you.

Regards,

I have the same issue but it's with the older R9 290. Basically every new DAG and it slows down the speeds a little.

On the r9 290 stock clock at 947/1250 I used to get like 26.5Mhs And nów I get like 24.7mhs.

It's basically some bug which happened with the Tahitis and Pitcairns and later the Polarises and now it looks like it might affect some Nvidia owners as well as the DAG keeps growing.

Either that or are you talking about your profits decrease? The price of ETH fell with respect to BTC and USD and hence your decreased profits are to be expected.

In my case Whenever the hash is lowered checking its clocks define has solve it

seems, other way around when my rigs has an unexpected reboot clocks settings are changed or back to defaults

still using MSI AB btw

my rig has 4 GPU. Today after a restart : 2 works at 15Mh/s and 2 works at 20Mh/s.

Last week All GPUs work at 15Mh/s. Normally all GPUs work at 22Mh/s.

I don't understand why performance change like this with algo GPU.
