Boost only mining eth for me. From something around 78MH to 87MH.
BTW not talking about memory OC, just reaching max original boost clocks.
Are you saying you are mining ETH@87MH? Windows?
Yes, with 4 gpus. 3x970+1x980 making 719W at the wall. All cores overclocked and memory of all gpus at 7000MHz.
I'm not tottally offtopic because I'm using the sp-mod version of the genoil's miner

The same rig makes 76MH in quark algo, consuming 840-850W.
