I'm having trouble getting SMOS to apply the power limits that I enter. My system includes 5 gpus, all Nvidia, 1x1080ti, 3x1060, 1x1050.
Yesterday I rebuilt the rig on an aluminum frame (taking it out of a tower box with gpus helter skelter). Now the hash rate is significantly reduced. I'm using the exact same components, mobo, gpus, psus, risers, etc.
I think the issue is in the power limit part, because when I watch the start up from a monitor, it seems to ignore the values I enter - somewhat. My overclock settings are:
Core: 93,200,200,200,200
Memory: 250,650,650,650,650
Power: 250,75,55,75,75
Here's what I see on the terminal on start:
===== OVERCLOCKING =====
Applying CoreOffset: 93 Memory Offset: 250 for GPU 0 with GPU Type: 3
Available power limit for GPU 0 is 60.00 W, 140.00 W
Applying PowerLimit: 140 watt for GPU 0
Applying CoreOffset: 200 Memory Offset: 650 for GPU 1 with GPU Type: 3
Applying PowerLimit: 75 watt for GPU 1
Applying CoreOffset: 200 Memory Offset: 650 for GPU 2 with GPU Type: 3
Applying PowerLimit: 55 watt for GPU 2
Applying CoreOffset: 200 Memory Offset: 650 for GPU 3 with GPU Type: 3
Applying PowerLimit: 140 watt for GPU 3
Applying CoreOffset: 200 Memory Offset: 650 for GPU 4 with GPU Type: 3
Applying PowerLimit: 75 watt for GPU 4
Any idea why it looks like my power limit settings are being ignored/changed?
Update: after fiddling with the SMOS settings for the rig, and MANY restarts, I got the hash rate 98% back, but I still see the power limit stuff as above. So the stated power limit isn't being used? The hash rate is what I want, but it seems really finicky to get it. All I did with the fiddling is changing settings this way and that. Now the settings are:
Core: 93,200
Memory: 250,650
Power: 250,100
Essentially the same, but results slightly different.
