If I'm reading and following this right, Claymore asked you to perform 2 things, you managed to do only 1, and now you r going back to him saying that it didn't help. That's really outstanding.
On a side note I had similar problems and managed to fix this by tuning the core voltages for each GPU separately. Now everything is stable and for the last few days I checked only twice the miners. For all people with similar issues, just by following simple logic -> if the miner works stable lets say for 10 other people, do you think it's the miner to be blamed?
It is not like I am bored or something. I do not have physical access to my rig yet. I will probably have this weekend.
BTW that 1 thing I didn't perform (setting default ROM)... yeah I have the same ROM as the rest of the planet does for that GPUs, which used to work fine before Blockchain drivers.
I didn't get the chance to set original ROM but I did remove overclock. Not only it didn't help but it got worse! In fact, while I was trying different OC settings I noticed that the lower I was setting my clocks, the more unstable my rig became.
My rig usually freezes after a GPU hangs or after a share gets rejected. The clocks I am using and the ROM I am using have been stable for months now with previous drivers and miner version
One more thing I have noticed is that after a rig restart (following a freeze) the miner starts, the clocks and voltages are being set normally but I get~ 3.5% less performance than usual. Once I restart the miner it gets back at 100%. Does anyone else have the same issue?
Me. And I have to completly shutdown the computer (PSU switch) for that to stop happening.
Also, I've set the default rom, just for testing, without any OC. I still get invalid shares on ethereum and a warning to check my overclock. (eu1.ethermine.org)
This guy tried default ROM but he did not left any feedback on the "Freeze" issue, after stock ROM, only on invalid shares.
Also, I did remove overclock, so "tuning the core voltages for each GPU separately" has already been done and it did not help at all. In fact it made things worse.
Reading posts like this:
The next bug i want to report is that in my opinion the dual mode (EXP + DCR) is buggy on systems with more than 4 GPUs (Win7 64bit, RX560). I searched over four weeks now for another possible solution but cant find it. I tried to undervolt, i checked possible GPU memory errors (HWInfo64), i checked the psu and the riser cards, i checked the intensity and othe options. I also tested to let the cards alone, dont changed anything on the volt or clock times. I checked the amount of watt for each card and made sure, thats its the same as for solo mode. Nothing helps. The systems with only one card running fine in dual mode. The system with six cards crashes coincidentally if there are more then 4 cards. And it dont really matter if i undervolt the cards or let them alone. It crashes sometimes after 20 minutes, sometimes after 6 hours and most of the times during i sleep :-)
is what leads me to believe it is not a ROM/Overclock fault.
I myself have one single same GPU in my PC,with same clocks, with same voltages, with same ROM, with same drivers, with same Claymore Miner version that runs just fine.
Yet my rig with 8 gpus keeps freezing frequently.
I am not blaming the miner, I am blaming the drivers but since AMD won't do anything I am relying on Claymore
And it is not like I am telling "fix it for me". I am gathering other people's experiences for @Claymore to decide if there is a common issue or not.
As for my self, if I have physical access this weekend rest assure I will try everything to specify the issue
Edit:yes is the miner and the driver
fixed issues with voltage/clocks management for latest AMD blockchain drivers (not completely).
That is what I believe as well
