is it possible to run S17 or S17 Pro in fixed-freq mode ?

[bobzombie]

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:

Code:

driver-btm-api.c:758:init_freq_mode: This is scan-user version

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

Code:

"bitmain-fixed-freq" : true,
"fixed-freq" : true,
"bitmain-fixed-freq" : "true",
"fixed-freq" : "true",
"bitmain-freq" : "600",
"bitmain-voltage" : "1850"

... or should i forget about it ?

This is probably the best thing to do, you are playing with a gear which you probably paid 2k-3k to get, besides you don't seem to fully know what you are doing, so the risk vs reward here does not seem so convincing, there is no data or information related to these new gears, probably nobody has messed with them yet and so shouldn't you.

Check this post below and maybe it might help you to remove the auto freq.

According to the post above you need to edit the /etc/config/asic-freq this is not for s17 miner but check that part and maybe you can find the solution by editing something under asic-freq.

Don't forget to have a backup for safety purposes.

That bugs me too. 2 boards run at a frequency of 422 and 1 with 522. The latter is clearly 18 degrees hotter and the fans are accordingly much louder.

Sometimes the miner freq drop or decrease if the hashboards are too hot the miner will automatically switch to the lower frequency.

Do you have any kernel logs to share? Post it here let's see if we can find the issue there and take a screenshot of miner status.

Try to test the miner with lower power mode you can find it under miner's configuration and monitor the miner's frequency if it will become stable. Also, try to clean the miner and test it again.
