Hi all,

I got my first rig up and running a couple of days ago, and have noticed that the different GPU's are reporting very different speeds in the console, here's a typical excerpt:

========== Sol/s: 1729.1 Sol/W: 2.57 Avg: 1754.6 I/s: 933.9 Sh: 7.26 0.99 50
GPU3 75C Sol/s: 327.6 Sol/W: 2.84 Avg: 326.5 I/s: 174.9 Sh: 1.33 0.99 55
GPU4 75C Sol/s: 295.6 Sol/W: 2.71 Avg: 296.4 I/s: 155.2 Sh: 1.17 1.00 44
GPU2 75C Sol/s: 150.3 Sol/W: 1.32 Avg: 151.4 I/s: 81.1 Sh: 0.66 0.98 43

The rig is still a work in progress as I'm waiting for parts, but it is currently running four Palit 1060 6GB cards and two Palit 1070 OC cards. It seems like two of the cards, GPU2 and GPU0, are seriously underperforming at 150-200 Sol/s, so I'd really appreciate all advice and pointers in the right direction for the best way to improve this.

My OC settings in SMOS are currently set to this, based on recommendations in the SMOS guidelines:

Core MHz: 150

Memory MHz: 600

Power Limit (watt): 115

Target Temperature ℃: 70
Minimum Fan speed %: 50

I'm not sure if I understand correctly how OC'ing works yet, but I've seen mention of making individual OC'ing settings, like "140, 150, 130..." etc. - am I supposed to do this to tweak each individual card to it's max efficiency?

I did one attempt at setting up such a comma-separated string and saved the settings, and the miner restarted, but I did get pretty much the same results in the console, so that's why I feel very much in doubt about the right direction ahead.

All advice would be very much appreciated - advance thanks! :-)
