Using an Avalon PSU to Overclock a Whatsminer MS30 with 2 PSU

[SwankyTiger]

Does anyone know if it is possible to overclock a whatsminer ms30 with an avalon PSU? I've seen people do it with stock PSUs but I haven't gotten mine to work with an old Avalon PSU. I'm not sure if this is due to the fact that the Avalon PSU might be programmable - not sure if that PSU is or isn't. Anyone here have any experience with this? I was curious if it would even be possible with the s19 power supplies, or if those need to be reprogrammed in some way to function as a normal power supply. I'm lacking the proper documentation to know - if anyone has any experience with the topic or could point me in the right direction I would appreciate it.

Starting with the A1041 Avalons have used variable output PSU's that is controlled by the miner software. Bitmain and Whatsminer's do the same. The reason is efficiency as losing the final Vcore regulators that used to be part of the hash boards and directly controlling the PSU to set the voltage fed to chips gives about a 10% increase in power efficiency.

That of course means that your miner control board must be able to talk to the PSU to set whatever voltage the miner needs.
You need to find what kind of communication is used, (simple voltage sensing or digital coms) and then provide the correct signals to the PSU.

Thank you for the reply. What does the testing procedure look like? Any guide or resource that exists online?

I think the PSU from Canaan is programmable because Canaan have some PSU firmware under their download page so I think you can't just make the Avalon PSU work on the Whatsminer unit due to incompatibility issue.

I tried to search and it seems there's no guide on how to make Avalon PSU work in Whatsminer units.
Why not, do the same as other people do using the stock PSU?

I have some extras laying around and wanted to use them as scrap. Where I live PSUs are expensive, but scrapped Canaan ones are not. If I go to the scrapyard, is there any guide to know which PSUs in general will work?

Is there any documentation in general of non-stock whatsminer PSUs being used to overclock the miners?

Sorry, but I couldn't find any documentation to overclock the miner based on what I searched on Google you need to flash the unit with custom firmware meaning you are going to use other firmware than the stock firmware.
And it seems I can't find any free overclock firmware for this unit. Some of the sites mentioned in the guide that I found on Google is not a well-known company I can't just recommend them but I found one site that sells this overclocked firmware for m30 and I think you can ask them if how does this firmware work or ask them what PSU are compatible to your unit once you flash the unit with their overclocked firmware.
