Topic: Failure!🎬 StrongU STU-U6 dash coin miner review. (Read 1756 times)

Seen there are still people having issues with the strongu bins..

I guess one of the most common failures ist the freq stopping at 170 and no hashing at all.

1.) Dismantle the whole creature and gently check if the tiny capacitors on the hashboard are still properly soldered onto the board. (470 yF/ 16V)
If not replace them with equal ones with wirelegs. It's a pain to preheat and solder the original ones with the shortlegs..

2.) Fire up the bin, wait 10 min. Get the Antminer D5 firmware and flash it. Yes right! the antminer Firmware. An Error Message will occour, but at least the old buggy shit will be wiped.

3.) Let it run for 10 min and get the strongu U2 firmware (SIA). Flash it and let it run for 10 min and then use the original firmware. Flash it.

Now it should find both boards again and start hashing. It will take a couple of minutes to reach the max.

Another problem are the fans. To run them more silent the Antminer fans are a good choice. (Nidec Ultra Flow, 1.63A) but make shure both are new. If one of the original fans start to die the miner will go crazy.. (resulting in the software to kill itself?)
On the control board there's a 3 pin connector next to the 4 pin fan connectors. The black wire of the fan plugs should be on the same side as with the 3 pin plug. In case the replacement fan wires are interchanged use a plier and pull off the plastic socket und turn it 180. (or solder the end of a dead fan in the correct order onto the new and most likley to short cabeled new fan)

Anyway.. don't forget to reset the stratums with your own credentials and keep hashing.

I see some ads on google and they advertise these miners has a hash rate of 660 GH/s are these fake numbers ?
If you check on the StrongU website i see there is only 1 model with 420GH/s

It only works in cold rooms. If temperature of the room ups to 25 celsius it burns,  sooner or later..

Same thing here... Miner just died and no more lights on it - just the lan leds are blinking .

Out of nowhere all stoped. Any solution for this?

Hello everybody! Can anyone sell me a working hash board on the Strong U6?

Please, some help... 

Thanks for your answer Bren77 but how can I conect with the miner to upgrade the firmware with no blue leds light and the ethernet lights lighting but fixed?

Hello guys

First of all, sorry for my bad English. Well I have a problem with my stu-6. Yesterday it was mining normally, I turned it off for a few minutes and when I turned it on again (without touching and changing anything) it stopped working.
Now none of the 4 blue leds light, only the two yellow lights of the ethernet cable (and neither of them blinks, just light). The fans do work but as I say none of the 4 blue lights and no hash at all.

Someone could help me please? Thank you

These were the biggest piece of junk miners I ever bought.  2 of them I noticed are completely dead now.  Won't even start to try hashing.

bad business practice from STRONGU with how this rolled out

did you find a solution yet?

so,guys...anyone having any problems with stu-6 units? i have inspected the miner and the dasboard-noting lose or burned. the miner resets after about 35 minutes,one board is mining with half the hasrate. its disastreus.

My machine is working on 1 board since yesterday. one board doesn produce more than 0.35gh with temperature somwhere around 35C and frequency is rising and lowering. 0 accepted and 0 reyected shares.
The other is fine. its yust confusing that the bad board is not totaly dead...


something else i found about this miner:

Re: Anyone mining with or have a StrongU STU-U6 dash miner?

Hi, just came across this meanwhile older post.
Donno if you've got your miner now, got mine in mid dec.

First: Stay away from StrongU. Long story short, they suck! Big time!!
Miner was used and full of dust, stratum and address showed that it was heavily used to mine the shit out of it. Bevor plugin i had to unscrew the fans and 'undent' the grilleys and confect a cable that would fit into the non EU standard socket.
Later on i had to unscrew the obviously avalon styled case again to fix the ridicolous airguide that for some reason got inserted into the space where another hashboard was supposed to be.

I assume the missing board would have been the missing 220 Gh/s to reach the proclaimed 660 Gh/s that was reduced to 440 after orders and payments.. (at least the resellers corrected the values, but not StrongU on their own homepage, such idiots)

Well, after couple of days i checked their site again, downloaded the recommended upgrade in hope to squeeze some more HR out of that garbage bin, but instead the HR dropped to less than what the old D3 were able to come up with.
By the way, it was no surprise to me that even after checked the 'keep settings' all the pool data got replaced with their own f2 pool data.
(XxJzaL4tiEf433RSceQKEXAE1ETgfG7zrm, XiSxkcz5u8onPs9a7nevLK219zDeHTkGZg -> both belong to wallet: 578806)

Lookup the addresses that were in the pools and their first occourence showed that this wasn't just routine checks, they mined like hell!!!
One of their own videos with some DCR miner revealed that they've used the same f2 stratum (for DCR of course), the respective address and the same password as on my machine. Scumbags!

Diggin a bit deeper brought me to the hidden menu (MinerMonitor). It can be found be either replacing the last word in the browser bar or by mouseright -> inspect element. And surprise, surprise, not a single chip without errors!
Unfortunatley no other entrys were visible, nor any logs..

Update: pretty scary shit, most of the files that ran after updating contained fragment of some DCR/HC miner. Beeing not a rocket scientist my assumption is that the few Gh that i could see is the blake part of the x11 algo that gets done, anyway.. the trashbin keeps restarting all the time now, loosing it's cgminer and i'm right about to use that piece of shit at new years eve to stuff it up with some hardcore firecrackers.

it seems one board is not working
can you post screen from miner status ?

hello i just bought a u6 stu but i only have 220gh while on the information sheet i can see 440 can you help me please i am new in mining

thanks for reminding me, didn't thought about that 
just took a photo, consumption is even slightly less then before, ambient temperatue is 15 degrees

Have you measured the power usage difference . I assume it uses lot more power then if generating more heat.
Manufacturer website still only firmware V1.7

it seems that this miner just dont like temp. over 50 degrees, in first test fans were moving at 100% to keep temperatures below 50,
I transferred miner to the original colder place where it was before and run tests again, here are the results:


original V1.7 firmware on nicehash

new V1.8 firmware

strong u6 v1.8 hashrate on nicehash

difference is more than 20 GHs and so far no problems, but there could be in the summer

Cool thank you very much.

I switched to nicehash, numbers are (unfortunatelly) same as before, no change at all 

I have added screenshots showing max and min avg hashrate in 17 hours
