any idea why this is happening? Doesn't make sense....

Like blissz mentioned, there is some amount of normal fluctuation in difficulty that will cause low points and spikes in the hashrate chart. Your chart, however, looks more extreme to me. It looks like your miners might be constantly restarting. The first 3/4 of the chart is mostly normal, but the last part (where the hashrate is bouncing between 0 and a high number) looks like something is wrong.

I'd check the status page on your firmware to see how long they've been running. If the time is low, then they're probably rebooting.

Warranty return is almost pointless when it comes to bitmain it will take you six months to get it back

Wonderful....  Sad

Assuming I'd have to pay shipping back to china, it would take a while for the D3 to pay back the shipping costs even if they fixed the board immediately. I guess it would be worthwhile then to take it apart and see if there is any way I could fix it myself.

I've had to ship two orders in the past few months to Bitmain for repair, 1 L3+ hashboard and 2 D3 hashboards.  In my experience, they're very fast on returning them.  My only delay on the first repair was because they closed for a week for holiday.  My advice, use USPS, and ship the boards using the 3-4 day option Priority International Express or whatever its called.  For a normal size box for hashboards it cost me $60 or so.  It arrives, then it will take them a week to log it into their system so don't freak out when it doesn't get marked received right away.  Once they do mark it received, they'll have it shipped out within 3 days and they usually ship it UPS red so it gets back to you in 1-2 days. Door to door it takes about 3 weeks.. not terrible as far as warranty repair return times go.  The fact that they ship it back to you express is fantastic since it shaves at least a week off your downtime.

The trick is to ship it directly to Hong Kong, do NOT ship to California or they'll put the board on the slow boat and you wont' see a return shipment for weeks.  Shipping might cost you more up front, but you'll make up for that in the mining time you won't lose waiting on California to get the board returned and mail it back to you.  They don't actually do any L3 or D3 repairs on site there, so sending it to them is just adding a middleman.

Did you have to pre-purchase a shipping label in order to fill out the repair ticket? As someone else mentioned, it is a bit confusing as the form for the repair ticket requires a tracking number, but you're also supposed to have the ticket printed out and in the box with the mining equipment.

Also, how did you find out that they just forward anything shipped to their California facility to China? I'm wondering if the extra cost to ship to China is made up for by the faster return period.

This has probably been asked before, but are you perhaps considering a similar firmware for L3+?  Smiley
Are you ready do a gift the L3+ for BlissZ for this target?
(without L3+ at-hand impossible do a FW for it)

What fecell is trying to say is that BlissZ doesn't own an L3+, so it would be very difficult to develop modded firmware for it.

I switched back to Antminer-D3-20171210_0-blissz.tar on the D3 that has the dead/missing hashboard. It shows up now, but the hashrate and frequency don't really look right. The hashrate is way higher than it should be. It looks like the avg hashrate at the top of the status page reflects the true total speed, but there is some kind of bug/glitch for the first chain? I have another D3 that hasn't had any issues, but with the same Blissz firmware the first chain shows hashrate way higher than it should. Finally, I have a 3rd D3 that hasn't had any issues, and all chains show what look to be correct readings. I have included some screenshots.

D3 with questionable chain0 that doesn't show up with stock bitmain firmware:


D3 the doesn't have issues, but with blissz firmware shows incorrect chain0 hashrate:


Any ideas?

open repair with bitmain, for US customers you ship to their US facility in CA

Thanks! I'm glad having it repaired in the US is an option. That should save enough on shipping costs to make it worthwhile to get it fixed. About how long did it take to get back?

man ive got 2 units doing the same thing (one board on each unit gone and log shows 0 asics)

i had this issue a few weeks ago on another board and I sent it to the US facility and got it back repaired.. but now a different board is gone on each unit LOL

and the board I got sent back has missing o's ( 9 to be exact) so instead of like

oooooooo oooooooo
it shows
oooooooo oooo

great repair service  Roll Eyes Roll Eyes Roll Eyes

.. so now ill attempt to send the hash boards that are now disapearing and see what happens.. not sure if i should send back the one with missing chips AGAIN

 Shocked geeze...that sucks. Was it Bitmainwarranty.com that you sent it to? Also, did you go through Bitmain's ticket/support system and then they told you to ship it there, or you just paid to have the US facility fix it since shipping to and from China would take too long?

Has anyone had to do a warranty return/repair? I have a hashboard that doesn't show up anymore on the status page.

This is what happened: I was running Blissz and it was showing me inflated hashrates on chain0 and failing with xxxx's. I rebooted and changed frequencies/voltages but nothing seemed to help. I switched back to the stock firmware and after some trial and error I was able to get chain0 to run normally. It ran for a couple of days and then just disappeared from the status page. I saw in the kernel log that it shows chain0 as having an asic count of 0 instead of 60. Also, I tried switching out the cables connecting the chain with cables that are known to work, and changing the slot it is connected to. I saw Bitmain also recommends reflashing the stock firmware and letting it run for 20 minutes, so I tried that as well. None of that worked, so it would seem the board is dead.

I don't know if I need to post on their support forum first asking for help, or if I can go ahead and create a help ticket, disassemble the D3 (removing chain0) and package up the faulty hashboard. Anyone know what the standard procedure is?
