Topic: How to fix large hash rate fluctuation? (Read 157 times)
Does this happen only on the ethereum, or on other algorithms too? Try for example a Monero, and you can try to use a pool where you can set fixed difficulty.
How are your risers connected from the psu?
What type of connectors do they have 6 pin , 4 pin etc.

GPU often throttle down after reaching the temperature threshold.
It could be a heating problem caused by the airflow depending on the cards position in the Rack/Case.
These cards might be in the middle part, yes?
Increasing the voltage more is not advisable for a stable overclocked card.
If it is failing to start, that's the cue that it needs a little more voltage.
Just proceed with a trial and error:
If you suspect that it's the riser, remove the risers and run the cards directly in your Mobo, then monitor the performance.
It might be the PSU's 8/6-pin connectors, swap the one that is connected to the normal cards to the cards with issues.
etc.

I have (
Powercolor RX 580 8g gold sample Gpu's. I have modded the bios and running windows 10 with the Aug23 beta blockchain driver and msi for overclocking. Using (2) 1000w powersupplies.
Most of the cards will mine at approx 30.2Mhs. However, certain cards will run 30.2, 30.3, 30.2, 30.1, 20.x and then back to the low 30's again.
I've adjusted the core clock down to about 1150 and the mclock to 2100. The hash rate goes down but the drastic drops are still there.
Most of the cards don't have this problem. I've tried upping the voltage to the cards that have this problem. Do you think it could be a riser issue on these 3 cards that are giving me grief?
Thanks for any advice.
