I have an X8STI-F motherboard running bios 2.0a (supplied by supermicro as the latest on their site is 2.0), the -12V reports -36,278.730V in BIOS and +1.9V in IPMI.

Any ideas? DC techs replaced two SATA drives with 4 SSD drives using SATA power splitter cables. Not sure if the problem existed before, any chance it's an SSD related issue? Or maybe the SATA power splitters getting pinched could cause this? I see on a SATA power wiring diagram that -12V rail isn't involved though.

Thanks for any help!

Bios voltage measurement is always shotty. Yours simply does not work, thats probably the max number the chip could output.

I don't think so tbh. I have quite a few of these motherboards, and only noticed the issue with this server and only noticed it today after SSD installation (it could of been there before though).

It appears to have been a bad PSU. Thanks guys.
