I have a mining pool for sha256 algo,
we mine BTC, BCH, BSV, DGB, LCC, FCH, ...
basically we support all sha256 coins

what i'm trying to achieve is that :
in some pools , i can see that you can choose the coin to mine from pool's website (no need to change miners configuration)
for example you login to website and choose to  mine BTC... and  then afterward you choose to mine BCH or .... (no need to change miners configuration)

i'm looking for a way to implement it based on miners username(workername), how can i switch users'  hash-rate between my different pools

I tried to use a forwarder , the problem is that in stratum protocol, at first miner send "mining.subscribe"
later miner send "mining.authorise" , with it's username


if i can trick the miner to send "mining.subscribe" again 1 more time after "mining.authorise" then now i can decide to which pool should i forward the miner.


I'll appreciate if some one can help me with an idea

It's working on S17 and  S17Pro
The settings are visible. no need to unlock.

I don't have the firmware to send you , but i have lots of miners with this firmware.

This trick is not working on normal firmwares of S17
you have to be on "Fixed-freq" firmware

Thanks to the legendary CK.

I managed to modify the code and add FCH to ckpool source code.

There is a sha256 currency called FCH FreeCash
Which pool software is able to mine this currency (and also support asic boost) ?

EDIT: i just found that video:

Antminer S9 - 6 Boards per Controler Modification

https://www.youtube.com/watch?v=D9Pfqcdx6BM



long time ago , Some where on the youtube i watched a video , but i cannot remember if it was S7 or S9 or what ..
but he added/soldered lots of resistors for each extra socket , also on the back of the board
as far as i can remember , that board was kind of like your board , but he soldered the resistors on somewhere like (on your picture) R138 to R140 , and R142 to R144 and ....

sorry for noob question

i have some Antminer s17 / s17 pro miners
with unlocked ssh , so i can ssh into them

is there anyway i can use them in fixed-freq mode ? (for over/under clock and ...)

for example :
is it possible to build s9 bmminer source code , for S17 ?
or should i think about reverse-engineering the bmminer or cgminer binary ?
or should i forget about it ?

in the kernel.log it says:


so it's auto/scan freq firmware
i tried to change cgminer.conf and tried these but still the miner is running in auto freq mode

please correct me if i'm wrong ,
maybe by increasing the difficulty to a higher value by using (if pool support it , for example) "D=512000"
Then the miners will send out less data (less frequently)

For s17Pro , it can goes up to 95'c

After 95'c probably it will hang or crash or restart or it's hash rate will goes down to zero
And for sure the life time of the miner will reduce.

Just don't let it go over 95'c

If it goes over 98'c , it will fry
I had one new s17pro which passed over 105'c (i don't know why) and it's dead now , burnt.

Hello sir, thanks for this great block explorer
one of the best "user interfaces"

i have a mining pool , and  i mine  some DGB & LCC coins per day
how can i tag my pool wallet address , so that instead of my wallet address , your website shows my pool's name ? (like many other pools )
