Hey guys,

So my R4 with missing chips (in kernel log) has returned by BM. It's now up and running and I can see that it's running 20161209 firmware which is a higher version than what's available on BM website Shocked

It also appears to run quieter (fan 2040 vs 2100 prior) and at a much lower error rate.

I hope this magic lasts.

So far I am happy with their services as they have opt to cover my round trip shipping.

I'm pretty sure the firmware is the same in the S9 and the R4, it uses a different controller, but the base code is the same with the exception of the fan control.

You can load any S9 firmware with a Xilinx folder to an R4 and it'll do everything the same until it detects only one fan, then it'll shutdown bmminer. You can also load any R4 firmware with a c5 folder to an S9. I haven't run them for long, they don't seem to like the others fan configuration, but it works.

Also my S9 board is fixed and hopefully on the way back soon. It's been almost a month since they received it as it had more issues than they were expecting. Hopefully it runs without issue. They responded quickly and helpfully each time I emailed, so a big plus for that.
