Re: [Work in progess] Burnins Avalon Chip to mining board service
20chips on BBXX = 9gh/s (450 mhz OC)
Till now i didnt find a setting that can do this. And it looks like the temperature the chips have are changing the needed mV to get the best Hashrate, so in theory each Temperature should run its own mV to get the maximum possible hashrate.
Where did you get that from? My 50 chips (20/20/10) run fine at 450 Mhz, 1.330 mV (it seems to overvolt slightly?) and cgminer "d" timing. Rejects and HW errors are reasonable. Temperature is around 47-49°C. Im stuck on the old firmware because of a broken USB connector or my hashrate would be closer to the theoretical 22.5 GH/s.
I have a feeling that these chips would much higher with better cooling but burnins (slightly crude) cooling implementation is hard to beat for price/performance.
Putting fancy copper/heatpipe heatsinks with expensive TIMs on them would probably not make sense from a financial standpoint.
