Just chat with oskar couple minutes ago,
here you guys gotta be aware of.

1. whenever you wanna change hardware, you must completely shut down your psu, certainly the standby switch too.
wait for the two orange leds completely off 10 seconds BEFORE you add/remove hardware ; or you might damage your hardware or motherboard.

2.after you flash bios if you are thinking use 5v rail for vdimm extension, you need to set vcore for non-auto setting and save bios then come back into bios, then you can see 4v option. It's probably the 1.25 and 2.01 bios got this circuit protection.


Looks like easy concept, but it's really easy to forget.
any problem we can discuss here.!
Hope it helps.
