Topic: What is the going rate for BM1397AG Asic Chips for S17+ (Read 222 times)

I the other hand do recommend you use reclaimed ASICS. Given the age of the Antminer 17 series, it’s impending obsolescence and the retail price of these chips, there’s two driving factors with regard to repairing these Particular machines. First you want it back up ASAP and secondly you want it done as cheaply as possible. You don’t want your ROI to exceed retirement. Fix your broken chain and ignore everything else to get your unit back on the line, do you want coin in hand when the value goes up again. If is has a black surface that won’t take solder, use S9 thermalsetting adhesive. Low Cores, no Cores, if it’s passing the hash data, run it. There’s only one rule when reclaiming silicon, the diode resistance values must match closely the average expected values of the others around it(Excluding the first and last chip); it’s a batch/bin/silicon lottery thing. Don’t touch anything approaching or exceeding the average by 0.1V. Take notice of the top and bottom irregularities of the T series, there’s a pattern and it’s normal.

A Hashing ASIC is two things, a collection of math cores and a communications watchdog overhead circuit. Your board only goes down when communications are damaged. When the upstream channel is damaged you get a non-zero ASIC count. When the return communications path(or any power failures) is damaged you get 0 ASIC.

I don't recommend you buy a faulty or scrapped hash board to get the BM1397AG chip. Because most chips have been oxidized or damaged during use. Even if there are good chips, you need to clean and tin these chips before use, and some chips will still have unstable hash rate even after tin plating. After all these complicated and time-consuming operations, you're not necessarily going to get a good working chip. If the connection to the heat sink is poor, it will lead to poor heat dissipation and may even burn your entire hash board.

you can buy failure hash board s17+ or t17+ and scrap it.
but be careful that hash board Intact and most of heat sinks be on chip.
by this way you have more than 20 chip and other parts of hash board with lower price.

I think its a fair price compared on zeusbtc price that I found here https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=230

But take note of shipping fees.

Also I suggest try to buy on other sellers there some sellers on alibaba offers $12 each chips or in aliexpress like this one below.

Getting Quoted around $25 per chip with MOQ of 10 from alibaba.

Is this a reasonable price?

Any other recommended outlets?
