Title: How to fix this R4 log?? [Fatal Error: DownOneChipFreqOneStep Chain[-1] has...] Post by: lazypolarbears on January 30, 2017, 02:14:13 AM Check chain[7] PIC fw version=0x02

This is an Antminer R4 8.7Th/s - Worked for a day then got this kernel log error (just copied pasted the end). I've tried everything: flashing the firmware, hard reset, etc... even tried moving the physical chains on the control board... Help would be nice - thanks in advance!!~ miner total rate=8889GH/s fixed rate=8700GH/s read PIC voltage=910 on chain[7] Chain:7 chipnum=63 Chain[J8] voltage added=0.4V OK: Chain[J8] is for this machine!

And no, so far it seems the only cure is sending the miner in for repair. Title: Re: How to fix this R4 log?? [Fatal Error: DownOneChipFreqOneStep Chain[-1] has...] Post by: lazypolarbears on January 30, 2017, 05:30:10 PM Thanks I appreciate it - tried looking for a thread on here first but somehow missed that. And thanks for the advice although wasn't exactly what I was hoping to hear.... 3 defective out of 18 R4's so far :<

And thanks for the advice although wasn't exactly what I was hoping to hear.... 3 defective out of 18 R4's so far :< Yeah that is about 16.67% I estimate a 10 to 15% rate for r4 and s9. So your rate seems normal. Title: Re: How to fix this R4 log??

The chips are heated highly, and the top right VRM chip started smoking in one.

the good board will run fine. 1 board attached been running for 2-3 weeks https://i.imgur.com/E1e4fWw.png Title: Re: How to fix this R4 log?? [Fatal Error: DownOneChipFreqOneStep Chain[-1] has...] Post by: lazypolarbears on February 11, 2017, 04:16:07 PM Well I have all 7 PCIe's plugged in as of current; they'll be shipped (whole units) back to BITMAIN in a week or so... I unplugged the one with the "Fatal Error" and that last post was making me so OCD that I just posted a new topic on S3/S5/S7/9/(mostly R4) fires ever occurring and in what situation....
4 defective or half-hashing out of 18 - this is ridiculous. Title: Re: How to fix this R4 log??

(7.5 and 8.7) they're still working. BITMAIN better not be slow about the repair/replacement... :/ |
