@Ada
No. they can not be mixes. Different version with different specification.
Can 1397AD and 1397AG be mixed and used interchangeably?
@Ada
The pic program is failed. Re-program the PIC with the Pickit.
Update the official website firmware results in the hashrate as shown in this image. What is the problem?
@Ada
Replace the IO port and then test again.
The hashboard can pass the single-board test but chip 34 RI voltage only 1.3V.
@Ada
Check the temprature sensor IC U88, replace it. Then there are domain voltage 8.5V and all chips hashrate [114],Nounce[912].
All the chips have been tested, but temperature 0 and all chips' hashrate reported as [00].

@Ada
It is possible that either chip 56 or chip 57 is faulty, or there could be an issue with the 0.8V voltage supply.
S9 single-board test showed Nonce [0] from chip 56, why this happened?
@Ada
No need to replace the chip. The hashboad is OK. Run it in the whole device. The hashrate will not be too low,
See the below single-board test result. There are 8.4V,8.5V domain voltage, replacing chip 1 did not work.
@Ada
See from the kernel log, the chains report 0 asic. Follow the 0 aisc repair process.
No hashrate, replaced several PSU, but did not solve it.

@Ada
To understand the initial problem, it is possible that the repalced chip are not compatible with the original chips. It is important to ensure that the bin numbers are consistent with the original hashboard when replacing with 9K chips. When retrieving chips from scrapped hashboards, make sure to select them accurately.
In the case of the S9K miner, why is there a decrease in computational power for hashboards 41-50 after the 40th hashboard?
@Ada
See above picture,there is only one fan. The fans are abnormal,
If the chips are confirmed to be in good condition but there is no computational power, how can we determine if the machine itself is functioning properly?
@Ada
The best way is by using the series-parallel 2-part method. If the chips are connected in parallel, it would be difficult to pinpoint the specific faulty chip. In that case, you would need to disconnect and measure each chip individually. However, if the chips are connected in series, you can remove the chip in the middle to determine whether the issue is before or after the removed chip.
How can we accurately identify which chip is faulty when the LDO resistance is abnormal and not functioning properly?
