hi,

i have 7 S9 and 2 R4
all of them working fine except first one S9 Batch 9
after 2 weeks from getting it i lost one board and they repaired it under warranty
after 2 months it stopped hashing again ( same board )
they told me it out of warranty so i send it to paid repair
after i get it and install it the all machine stopped working!
after reset i found the 3 boards stopped!!
i told them and they told me to send the 3 boards to free repair and they will cover the shipment cost
after 2 months one of them stopped again!
i send it to repair but they told me it damaged and cannot be repair or replace because it out of warranty
i told them to give me new board but they told me to purchase anew one from bitmainwarranty

i send message to bitmainwarranty to purchase a new board
i get answer from Ashli told me it will cost 175$ + 25$ for shipping
i paid using BTC
and after that he told me that he told me wrong price and the correct price is 550$
i told him to recover my BTC and i don't need this board
he told me ( My apologies I will go ahead and just ship the order to you. )

after i get my new board and installed it by 8 horus it stopped hashing!
i send bitmainwarranty a message from 2 days and i don't get response until now

I have struggled with s-9 gear and with r4 gear.

at the moment  I have an r4 blade at bitmainwarranty.

they have had it since May 25th  1Z4AR6880343709452

this is a short time due to Holiday.

I am getting  comp mining credit from host.myrig

I mine alt coins with https://simplemining.net I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Got a hunch the $175 would have been a repair price.

I was wondering why when I sent in a s9b13 board for repair Ashi also provided quotes for 550 & 600MHz spare boards. Perhaps was from your input.

Ya if you have had that much bad luck with the same board in the same miner you should start trying to narrow down the cause of the problem and start looking at your power supplys as well as all the wires and plugs going to the board in ? that keeps dieing on you.   esp now that they have had to of been plugged in and unplugged a few times now just from dealing with the board issue so many times.   PCI-e female plugs are only rated for a maximum life of 30 cycles of plugging them in and unplugging them before failure even in the best conditions.  They really are not meant to be unplugged more then a few times in their life before they need to be repined. and really not even meant to be pushing as much amps as they do when used in something as power hungry as an s9



and if its not a power supply issue or plug and wireing issue I would start looking at things such as the fan or what sort of temps the air intake air is at where ever you are running the miner that keeps haveing a board die on you over and over.


Or you could just have really really bad luck.  Which can happen.

before i get the board i moved this machine to new apartment that have more good air flow because we are on summer now
and changed the PSU too from EVGA 1600G2 to APW3 which i get it from one month from bitmain ( i have only one APW3 )
when this board stopped hashing i tested it on another data cable and start the machine with it only but it still not working

Apparently bitmainwarranty is going to be merging with myrig or something like that based off of the myrig guy's posts. It's an interesting service they offer, I'd look into their physical hosting once they get miners back into their marketplace.

i don't get there answer yet  Undecided

Well I am earning on the   site  I am more then 0.01 earned  which is nice but no info on status of the r4 board
Just got the email from Bitmain Warranty saying my s9 b13 hash board is fixed. Total cost including shipping back to me was $250 minus a very nice repair service Beta Testers discount..

The board was repaired in 2 weeks, Love it! Now to see if they include a service report at least outlining what was done to repair it...

Phil, any word on your R4 board?
