Re: The Habanero - 650GH/s - Batch 2 Shipping June 9th, $850 ($1.3/GH/s)
Well I spent a good bit of time breaking the rules and testing higher voltages / clockrates and cooling configurations. I am by no means suggesting that anyone attempt to replicate! I seem to get the best performance with the following settings...
Voltage: .995V
Clockrate: 975Mhz
Temps: 94-99
Hashrate: 750 GH/s +/-
Kill-a-watt: 1157
About 60 watts are from some ridiculously powerful fans that I swapped out with the stock fans on a CoolerMaster 240L. I started this machine around 5AM CST and it was running at 750 until this afternoon when it dropped a little. Perhaps that was due to increased ambient temps which were lower overnight, and are in the mid to upper 70s right now. I just took these screen shots a few minutes ago.
More tweaking to come, but pretty optimistic so far.
