Old Env: AMD Driver Version is 17.3 (prior to Blockchain beta), WattMan is installed, Windows 10 Pro 1703. Mix 4x AMD RX580 and 4x nVidia GTX1070 GPUs, Claymore 9.8.
I have used this claymore command line argument to control AMD GPU setting for long time. I found it was great because you can automate the miner and GPU setting during reboot.
-cclock 1150 mclock 2100 cvddc 900 mvddc 900
But since I upgraded to Blockchain beta (to resolve hashrate decrease/DAG issue), I cannot use Claymore to control AMD GPU setting anymore. I have to manually set it every time in WattMan for each RX580 after reboot. Automation is gone. If I just use Claymore command argument to set it, the setting will reset to default randomly after mining some time. When setting resets to default, you have much longer hashrate but use a lot more power and temperature is much higher.
Current Env: AMD Driver Version is Blockchain beta, WattMan is installed, Windows 10 Pro 1703. Mix 4x AMD RX580 and 4x nVidia GTX1070 GPUs, Claymore 11.2
I have tried some versions of AMD Adrenalin drivers with Claymore 10.x and 11.x, but none of them can maintain setting consistently for long time (10+ hours) w/o reset.
I heard some people use AMD Adrenalin 18.3 drivers with Claymore 11.x achieved -cclock 1150 mclock 2100 cvddc 900 mvddc 900 consistently (4+ days w/o crash). Can you provide me your env settings?
What version of AMD driver you use?
Do you have AMD WattMan installed?
You Claymore version?
Do you mine with RX580?
Another reason I havent tried Claymore 11.5 or 11.6 is because someone said claymore will regenerate DAG very hour when they start DEVFEE mining. That would be a serious stability issue. Is that true?
Thanks
use the latest AMD drivers, see my earlier post (Radeon Software Adrenalin Edition 18.3.4 and Claymore 11.6 version), if you have trouble, boot to safe mode, remove the AMD drivers using DDU tool (
http://www.guru3d.com/files-details/display-driver-uninstaller-download.html) and install the fresh drivers again.
In past, I had the same issue where claymore earlier versions can't control fan, temp (won't show these values) and OC settings, removing drivers using the safe mode, fixed the issue for me.
I am using these settings now for one of my rig, OC values gonna be different for your card but these switches really help.
-ftime 10 -tt 70 -fanmin 45 -fanmax 65 -tstop 80 -tstart 50 -cclock 1135 -mclock 2200 -cvddc 850 -mvddc 850 -platform 1 -eres 3 -gser 2
i have wattman installed but never touched it
Thanks a lot for your info!
I was able to control fan speed, set tt, tstop, rstart, etc. with blockchain and claymore 11.2. I think the command argument acutally works when you start the miner. The issue is the setting cannot stick very long. It always reset to default after awhile, then all thing gone bad from there (slow hashrate more power draw and high temp).
FYI,
all my rigs are running very stable now. They can normally run 2~3 weeks w/o hang/reboot. And nVidia is fully automated via Afterburn. Only AMD RX580 need to manaully set after reboot in WattMan, which takes about 2 minutes per rig after reboot. Do you have afterburn installed on your rig? Since all my rigs are mix RX580 and GTX1070. I have afterburn installed on every rig even RX580 doesn't really need it. In fact, afterburn's voltage tweaking has a offset, it is always higher than WattMan. No matter what I do, the last thing MUST be set in WattMan to prevent afterburn voltage spike. This was not the case prior to blockchain beta. Claymore arguement override everything else. I think the problem through my observation is something else is overriding claymore settings in blockchain. Maybe 18.3 is the way to go.
