Hey Guys,

Just thought I'd share my Rigs with you and I was hoping to get a question answered.

RIG1
3x AMD 7950 (2x Powercolour and 1x Sapphire)

I have a question on RIG2, my CGMiner settings are:

--scrypt -o stratum+tcp://FTC.XXXXX.COM:5565 -u XXXXXXXXX -p XXXXXXXXX --api-listen --api-allow W:127.0.0.1 -I 13 -w 256 --gpu-fan 30-95 --temp-target 75 --gpu-reorder --gpu-engine 1050 --gpu-memclock 1500 -g 2 --thread-concurrency 11600 --gpu-powertune -20

I use TeamViewer to manage the rigs and when I mine and have TeamViewer open and connected, my cards all run stable at 712-720KH/s outputting 2.88 MH/s avg.

now what happens is...if I close TeamViewer, and check my stats in the pool, my hashrate drops to anywhere from 500 - 650 per card, and then the second I love back into TeamViewer I see the low hashrate..and then they all climb back up to 712-720 KH/s.

has anyone experienced this behavior? I was wondering if I needed to make GPU dummy plugs, but I was told AMD drivers fixed that a while ago so we dont need to use VGA dummies anymore.

Any ideas ?
