The hackerfarm server was marking half of its RAM as failed. Fixed it by *removing* a chip. Still dunno what it did.pic.twitter.com/M4ykmgM61u

Protection diodes maybe. Just guessing however.
Doesn't make a lot of sense. Pinout was +3v3, GND, unk1, unk2, Vref, +1.5V. unk[12] were at 3.3V during normal operation

After some reading I wondered if it was a I2C DAC finetuning the voltage. But still doesn't make complete sense :-(

No make no sense at all. The cap between the bottom left pins invalidates them as data lines. Must be some analog thingy.

Currently my best guess would be something to ensure proper power sequencing.

Could be, or a monitor of some kind. But it's weird they'd need special sequencing for Vref... And it works without.
