Nice,
But whats the TDP of the chip and how will you place the heatsink inc. cooler so thight to eachother.?
Do the coolers share the same mounting hole in the middle ?

Why not, its just a test board and there's plenty of board space. For the retail boards you just don't dont drop PCI-E connectors through and leave them as empty connections. I personally would have preferred the chips to be centralised and squashed together more so we could have used standardised PC heatsinks cooling all 4 chips. 350W can be done with one higher end air heatsink or basic 120mm watercooling. I think its time we moved away from these strange aluminium blocks with obscene fans to make up for the low surface areas. |

Will these need extra coolers like the hex4m? if so how many and what socket?

Nice. Did you write cgminer driver from scratch or did you rewrite miner_gate_arm? |

from scratch If you don't mind answering: 1) Is it open source/can I see the code? 2) Do you do dynamic voltage/freq scaling based on wattage/temperature limitations? Then did you notice that the "BIST" in ASIC fails at lower frequencies then real jobs because of power drop at beginning of job - it might get you few more GH. 3) Is the driver inside cgminer completely or is it different process on the system? Thanks. |
