Topic: Need help troubleshooting bad S5 (Read 406 times)

do you bought it from bitmain ?
if so you can send the repair there if you found it a bad "good" and they fix it for you.

HI all,

I have 2x S5s.
One of them works fine, the other is set up identically, can connect to the netwrok, can see the mining pool (slush, but I have tried others), has lots of "GetWork", but everything is "Discarded".

Here's the kernel Log which I think is telling me the problem:
<<<>>>
[  658.255756] chain exist: 3, g_TOTAL_FPGA_FIFO 0x800,g_FPGA_RESERVE_FIFO_SPACE{4}
[  658.265061] g_FPGA_FIFO_SPACE 4, fifo_space{606}
[  658.269886] ret_nonce_num = 0, snd_to_fpga_work{387442}
[  658.275360] total ret nonce num = 0, diff1_nonce num = 0

And here is the same info from the Kernel log of the machine that is working fine:

Any ideas.....? It looks like the "nonce" is wrong....

Any and all comments much appreciated.
