Does this firmware work on the s9SE version?

i thinks yes ...

i have tested S9SE firmware on S9K with no problem ...

so you don't take a risk if you test it ...

if don't work, just make my "tutorial" and flash your original S9SE firmware ;)

Any chance of reuploading the files, they were removed by the upload service!

Hi, i have re uploded files, please leave comment ;)

Why my GH Target reads 30 TH ? https://iili.io/d2fd41.png

very strange... please give me "full" miner stat image. If your miner have problem before, my mod not solve this...

You have installed on S9K ? my mod is only compatible with S9K and maybe S9SE , any other miners...

I think it's normal, I have seen a few gears that have some weird target hashrate but as long as the actual hashrate is within normal range then all good, but that doesn't seem to be the case here with 12.5TH assuming his gear is S9k it has to be over 13th for all batches/versions unless he has a few bad chips here and there.

elfarto69 how long has this miner been online for? also, what was the average hashrate on the stock firmware?

Miners are supposed to be 13.5 TH/s, and that's more or less what they yield. How is GH Target calculated ?
Here is a screenshot of the stats page:

Why can't you post a complete image of the miner status page? you can hide the pool/worker/wallet details, some information at the top of the page is important.

This miner have a problem ... 0.3HW is BIG !!!

so, don't send full stat, don't help ... is easy ? lol

The problem is that the API call that reads the frequency uses  the bitmain-freq value from the config file, in these S9K asics the value is irrelevant if present yet the API returns this value.
Since the UI uses the API call to calculate the hashrate it gets the math wrong. removing it from the config file resolves the issue.

So i have tried installing your firmware using SD card. Red and green light LEDs stay on. 20mins later they are still on. No difference. Doing upgrade route from web page gives me Cannot Find Signature!!!


Any suggestions?

All I want to do is underclock this PoS.

Do you have any extra SD cards? Maybe your SD card is damaged or an SD card that always corrupted when transferring files.

Try to use a known working SD card and make sure to use this firmware (https://easyupload.io/wnryfq) as the guide above and make sure you push the card to the slot properly. If it doesn't work repeat the procedure remove>turn off>insert card>then turn on the miner check the lights if flashing.

Since the lights flash constantly i think the sdcard is fine, but maybe the way he puts the files on the sdcard is wrong, the files need to be in the Sdcard directory itself, not in a folder whatsoever, I see a lot of people make this mistake, if files are correctly placed then using another Sdcard is the next best move.


Not sure if this modified firmware will allow you to underclock it, wait for thierry4wd to confirm.

Yeah, in addition, the file above needs to unzip/extract and maybe he just directly put the whole zip file into sd card without extracting the image from SD mptesfirmware T17-S17-S9K-S9SE.zip.

That's why he said "The LEDs stay On" but not flashing it means the files he put are not recognized.

@Keezasa

Make sure to extract the file from the zip file and copy all files from the folder you extracted including the image and paste it to the root of the SD card.

I noticed the fan control option only affects FAN1 and not both of them. FAN2 runs at full speed.

	FAN1	FAN2
Speed (r/min)	3840	5280

Hi, no this works fine on both fans, in reality on almost all minors the 2 fans are different, in fact for the same% one fan will run faster than the other, just try to reverse the connectors of the fan and you will see;) or, for example, apply 30%, and you will also see;)

Thanks for testing my tiny mod :)

Sorry i am bit late to the party, i couldn't find Your version of S9SE or S9K on your site https://www.djayos.com only S9.S9I.S9J.T9. Have you removed it?

no sorry, i just don't release on the website... if you want file, just join my discord, i give you with pleasure.

Just FYI This S9k Firmware does work on S9SE.
LPM function does not work, But Fan control works. Which is AWESOME! 8) ;D
