Almost everyone on yiimp x17 uses ccminer 2.2.4. On zpool it's ccminer Alexis.  You can see this by looking at the bench tab. Seems odd the two use different clients.

I am trying 2.2.4 tonight. It runs the GPU cooler than ccminer Alexis and pulls less power. Hash rate reported by the client is lower.

I'll let it run 24 hr and if it really does run slower I'll go back to ccminer Alexis.
