That offer is pretty expensive I don't know if someone will take that offer just to fix or replace the heatsink.

Actually, you don't need to hire Bitmain or someone to reattach the heatsink back to its position you can do it with your self you just need to buy a thermal adhesive to put them back to the hashboard.

$300 shipped to the US is very expensive.
That is almost what it would cost to have a CNC place do it here.
Yes I know you would need to design it, and create the CAD drawings and so on. But still that is US cost not China cost.

How much extra hashpower are you actually getting out of the firmware upgrade and are you still using stock cooling?

You are wrong. This cards need 120w for ETH - you can´t use the software reading for this - AMD only show the TGP in every software - so you must add around 30-40w to every card.

Example - Teamredminer show 530w for one of my RX570 rigs - from the wall it is 880w.

Same for Nvidia, but here you must only add around 10 - 20w per card to the software readings.

Yes i know no one will hear this and no one will trust to my words, it is so annoying that so much people don´t trust to my words every time. But you lie to yourself if you think such software readings are the truth.

POW is based on hard iron real gear and the worlds electrical grid. It has Real infrasturcture.

and ETH is more likely to not go to POS than it is to go to POS because it is certain to fail if it goes POS.

I did use https://great-voyage-inc.myshopify.com/ for an S17 Pro power Supply repair (APW9) recently
They are legit. Getting a repair is kind of confusing. You create a repair request on their site and send in. Then email for confirmation. I also joined their telegram chat for more immediate questions.

I was however very disappointed in price. Half of it went dead, that is 2 of the 3 fans (as powered by one cord) stopped. Expected it to simply be an integrated fuse, but they of course did not say. They never advised of estimate to repair (I failed to ask ahead of time, too exited I finally found someone that would repair power supplies) and they only said done, total due $250 ($200 repair and $50 return shipping. It only cost me $14 to ship to them the via my UPS account.) However, as you can't find one for less than $350 now and days, I had to take it.

I may give them another chance for a hashboard repair as my regular company is 90 days out and they turned the power supply in about 3 weeks. Telegram chat suggests they are similarly fast on hashboards. But I will ask for price quote before repair

I just sent two S17+ hash boards to New Voyage USA, ordered through their website - 4 day turn around!  Boards being delivered tomorrow.

It's good that you have picked this one, as I said before I personally trust zeusbtc and can vouch for them, I have had many successful deals with their founder even long before I knew he was the owner of zeusbtc, a very genuine and trustworthy person, but if zeusbtc tell you they don't guarantee the folks listed on that list, then you should be careful, I know they don't randomly list everyone but I highly doubt that the due diligence is good enough.


I know that "Alpha Miner" which is owned by Mike and their website is www.alphaminer.io is legit, not sure if this "Alpha repair" is owned by the same company or not, I will hopefully have the answer by tomorrow and will let you know.

Edit: Mike replied, they are not related to the "Alpha repair" at all, using a similar name to a company that already exists makes me doubt them, I would be extra careful. 

Zeusbtc is a well-known site here on the forum where you can able to buy parts of any ASIC machine and partner with trusted repair companies.

They have a list of US-based repair shops look at this link https://www.zeusbtc.com/RepairCenter/USA/

Have you asked through the repair shops listed at www.zeusbtc.com ?

I have no idea how you got to 1.2gh on a rx580, maximum I got with a rx580 was 900 mh, well core was low at 1200mhz, did not try 1450mhz but even if got as high as 1450mhs that 1.2gh would also be impossible in my calculations. 900 to 1200 is 30% increase, that also would mean 30% increase in clocks or even more than that, meaning 1200mhz + 30% would be at least 1600mhz and a rx580 is impossible to get to that.

It's funny, your rx590 got as high as 622 mh and your rx580 got as high as 1.2 gh which is double of that of a rx590 hehe, what the hell happened there? hehe
