It just looks like a replacement for the 14V Buck Converter that feeds the LDO on the Top 3 Stages. I guess it's intended as a replacement if you have a failure? They have removed the inductor but left the U101 in place, also looks like you can also adjust the voltage.

Rich

I saw voltage on it and was curious with that.   With being able to adjust think it will see any eficiency change?

Or mainly just a fix and that's it.

No it's just a rather complicated and expensive way of repairing your 12V to 14V step up converter, by completely replacing all of the circuitry. Not a lot of value in the adjustable voltage as it needs to be set a couple of volts over the supply voltage in order that the LDO Regulators will function.

So, i'm wondering, is the 16 pins pinout otherwise the same as the 18 pins. In short i'm wondering about running a 16pins blade into a 18pins controller safely. I'm pretty sure i read somewhere that it was done, can't find it now, so i'm wondering on how to do it safely.

Anyone knows?

Hi,

I'm looking for a working controller board of S5 miner (that is, only the controller board, not the whole miner). Is there anybody with broken S5 miner, but with fully working controller board? If yes, please contact me, I would buy one (only the controller board). Or is there any other option to get a controller board of S5 miner (btw: I don't want to mess with bitmaintech for this, it would take too long to get it from them I guess). Thanks!

I have a S5 with some history, the second blade was dead and the FAN2 from the controller reading does not work. I could put a new working blade in the controller, but would such history warrant against doing this?

Just wondering if the replacement board could get damaged because of the previous history, or if it work now, it'll be fine?

Looking for an electronics expert input.  I have 4 working S5's all with 18 pin connectors and 1 S5 that is a 16 pin variety.  I have taken the S5 that is 16 pin apart because 1 of the blades wasn't functioning and I had a couple of extra blades I wanted to test.  So essentially I have 3 16 pin S5 blades.  When I connect 2 of them to the controller board I get what is in the following picture regardless of which 2 are connected.  I assume it is a controller/BB problem but have no idea on how to test it since my other S5's are all the 18 pin variety.

Just to check one thing first, you say.  "I have taken the S5 that is 16 pin apart because 1 of the blades wasn't functioning"

So the blade that was working, if you plug that up on it's own is it still working?

Now moving onto the screenshot. Do you know the history of the other two 16 Pin blades? if you do and they were working then the obvious implication is that the controller board is faulty?

Now they all show up as they do on the screenshot.  The only difference between the 3 blades is that 1 of the 3 still has the red LED that lights up.  No obvious signs on any of the blades, I have about 30 blades that are fried (for the POD project) and most of them have an easily identified problem.

Only one of the 3 blades is known to work

Can you please tell where to find the datasheets on the S5. Thank you.

Thank you, but I have not The user guide and datasheet itself Asic. Stops working and you want to learn how to restore it. On the chip found - https://www.bitmaintech.com/files/download/BM1384_Datasheet_v2.1.pdf, but the device - no.

has anyone gotten cron to work? the file (/var/spool/cron/root) would revert back to the default after rebooting the miner

[DarKSm0ke]

Hello Guys,

I have some issues with my S5. I have sent board to Bitmain RMA and when they came back after putting them together and starting the miner, all asic are detected but it won't stop mining.
Even after multiple resets to default setting, lowering clock frequency etc..

Do you have an idea what can be the cause and how to make it mine again?

You had it in to bitmain rma, it came back and will not hash, right?
Check connections
Test power
What lights do you see?

Here is a guide for how to check the hash board, but tell us more about your particular situation.

Thanks for your advises.

We were able to make it work finally. It was an issue with the fan. There are 4 fan connectors on the controller board and apparently if you don't plug it in the correct one the software is not happy and won't start mining, even if fan is plugged in an running.

It just looks like a replacement for the 14V Buck Converter that feeds the LDO on the Top 3 Stages. I guess it's intended as a replacement if you have a failure? They have removed the inductor but left the U101 in place, also looks like you can also adjust the voltage.

Rich

I saw voltage on it and was curious with that.   With being able to adjust think it will see any eficiency change?

Or mainly just a fix and that's it.

No it's just a rather complicated and expensive way of repairing your 12V to 14V step up converter, by completely replacing all of the circuitry. Not a lot of value in the adjustable voltage as it needs to be set a couple of volts over the supply voltage in order that the LDO Regulators will function.

Rich

so is this some possiblity to fix burned boards by doing this?. seems that u101 chip is mostly the failure. and you cant purchase a loose chip .

Yes although their add does not say as much I see is being an "easy" way to repair your 14V upconverter that supplies the LDO's in the top 3 stages in the chain. How often U101 or other parts of that circuitry fail I do not know?

looks like the piece?.


i've been researching seem slike a common failure when short circuit the board,and u101 chip seems impossible to get.

If you want to just replace U101 then the part to look for is  RT8537 - Current mode Boost-type LED driver

However not sure how easy they are to find?

If you have defective S5 boards in EU, without any chance to get them exchanged by Bitmain, I'm interested to buy them if your price is fair.
And I'm also interested in 12 to 20 defective S3 boards, just in case someone have a few laying around.
