Hello doktor,
My hashrate still drops with vega 64, even with 100% fan config in afterburner (8500 to 6000h/s for 6 gpu) after few minutes.
Do you think it is better to use overdrive for this or it will change nothing?

Is it a driver problem? I have Amd Crimson 016.001.001.000 , should i change?

Last question: i can set my mem clock to 1100 max, after this, it reboot my computer, is there a way to go higher, or will it change nothing?

Thanks a lot for your help!

I don't have Vega cards but i found on many many places on the net that vegas hashrate drops, so its not a miner related problem.
Maybe someone here who has Vega cards can help you ?

Yes, its not miner related.
Vega driver will monitor the temp of the CORE to adjust the fan rpm. But the key temp that causes hash drop is the HBM temp. Thats why people used to set the min fan rpm to 3000. HBM temp must be bellow 70!
Nobody mine with Crimson driver. Blockchain is the most used one. And yes, expect many bugs.

What is the Vega hash and config with this miner?

Hello, thanks a lot for your answer.

My settings : intensity 60 (maximum before crash ) bad hash when louer.
Double threads True.
Max température : auto.

For the gpu : mem clock 1100 (above crash and computer reboot ).
Core clock 1400.
I cant settle the mV on afterburner even after activating it on the advanced settings.
Fan set to 100%.
I use msi afterburner.

Hashrate : 1400-1500 per gpu at the beginning (so 8.5k total ).
Drops to 900h/s per card after few minutes.
