Chips say they reach 30 C on the miner's IP website. Seems like a possible error in the firmware to me, considering the voltage does not show up correctly when using 2 PSUs.
Is there another way to connect the PSU apart from commoning the ground?

The surface temp for the machine never got hotter than 50-55C as the firmware would stop it from doing so. I can run at 93TH forever without the power supply. When I connect the supply, it runs for about 10-20 minutes at a comfortable 100 TH before stopping, and then it only goes up to 50 TH after that.
I have a whatsminer MS30. I scrapped a Core Scientific DL SeKU-2R5S12 power supply with an input of 100-240VAC 50/60Hz 15A max and an output of 13.2Vdc/184A @230Vac 13.2 Vdc/116A@120Vac. I made a new board out of aluminum with the leftmost connection between the board and the power supply cut off (the one that looks like an L) and connected that one to my power supply, as detailed here:
https://bixbit.io/en/documentation/connecting-an-additional-power-supply-unit/2-the-connection-procedure-of-the-additional-power-supply-unit .
On startup, I am able to get it to about 100 TH until it seems to overheat and I get error code 5050. The new PSU is connected to only one hashboard.

So you commoned the ground from both psu's.
how long do you run at 100th vs say 90th or 85th.
It could simply be too much energy and unable to cool.
also how hot do chips get.
if you run for 10 or 20 minutes you just may be over heating

Um, model number?
MicroBT (Whatsminer) have many different ones...
And - I hope to God you have not just connected the PSU's in parallel with each other or have 2 feeding 1 hash board... Use 1 PSU to 1 hash board otherwise they will constantly fight each other leading to the Majik Smoke escaping...

Anyone here know the procedure on what frequency and voltage to set whatsminers at using bixbit when overclocking with 2 PSUs? I'm having errors connecting a PSU currently and I am pretty sure it has to do with how the machine's settings are configured.
