Hello. I come to you because I am having a problem with one of my cards.
Since a hiveos update, I have a card, for which it is impossible for me to overclock.
Fans drop to 0% on the panel and I have a third of the hashrate.
My research:
Change of riser => NOK
Change of power cord => NOK
Inversion with another card => NOK
Revision of OC => NOK
Flash of the SSD then new installation of Hiveos with latest drivers => NOK
Same problem with any miner.
The card works well under w10. No error in device management.
Don’t run at default settings. Find the highest stable mem clock and the lowest locked core clock that maintains full hashrate. No power limit needed. Each crash reduce mem clock and reboot until stable.
If I understand correctly, I have to remove the default OC, launch the card without power limit and, each time it crashes, the memory will be reduced automatically? As if the card had a hidden oc that would be too high? Sorry for the understanding, I speak very bad English
Because I have already done a similar manipulation. Everything was stock, no oc, and as soon as I increased the memory by 200, it crashed directly
No, don’t run with no oc at all, this isn’t good for the card, and wastes power/makes less etc etc. there no up side to running without ocs.
Find the highest memory clock for each card, as high as is stable. If it crashes, lower it. Once you’ve found this memory value, find the lowest locked core clock that maintains full hashrate. If you can lower the core clock and hashrate doesn’t fall, you’re not low enough.
After setting your memory and core clocks if you have any instability (crashing, driver errors, 0% fan, and are sure that it’s not a hardware issue with the fan itself) reduce the memory clock and reboot. Repeat this step until it’s stable.
Hello. I applied what you explained to me. Only, with the GPU concerned, I can’t do better than what you see on the screenshot. It’s strange because in the past I could mount the memory like other cards, around 2400/2500. I’ll go with it. Anyway, many thanks for your help.
As soon as posted, as soon as planted!
No matter how much I lower my memory, nothing changes.
I’m losing hope with this card. I don’t know what she has.
In this case, I misunderstood the explanations. When you said that after having oc the memory, it was necessary to find an oc core as low as possible.
Sorry
Yes the lowest locked core clock that maintains full hashrate. Negative values are offsets from the boost clock. There’s no need for power limits with locked core clocks either.
Ultimately, it’s not resolved. Whatever the pcie port used, the problem remains the same. My GPU doesn’t want to know anything.
It’s strange. No errors under w10 and impossible to use it on the rig. Fans drop to zero and hashrate decreased by 2/3.
I changed the riser, usb cable and riser.
I’ll run it on the rig and report the behavior to you.
