I was one of those claiming to be getting a greater return from the MultiPool then hashing directly. I still believe this to be the case when I am using the x11 pool. I have 4 x HIS 7970 and running on the dedicated pool I was getting around 150-180 UTC per day with an average power consumption of around 1.1kW. Using the multipool with x11 I am getting around 220 - 270 UTC per day (using LTCRabbit kernel) and pulling ~730W. In this respect I'm loving the multipool and really appreciate the effort CryptoTrain has gone to, only thing left is a European stratum

7970 is almost like analog 280x (updated)? 150-180 UTC 4 cards at 0.04-0.06 complexity is very small. Maybe you did something wrong configured?
I 4 * 280x and 4* 270x get from 500 to 700 in the direct production UTC. 4 * 270x do little more than 50% of the 4 * 280x.
some 4 * 280x should give about 350-450 UTC for 24 hours, and you have 2 times smaller the reason.
About energy consumption can not say - nothing to measure consumption in real time.

CryptoTrain thank you for your work.
