X399 Woes

[keeph8n]

Been running into a lot of issues with X399 and LN2 on the MSI Creation. After about -50C or so I get random system freezes and the like. I have used the “slow mode” jumper and yes it does slow the system down, but doesn’t get rid of not being able to drop the chip down. 

 

Am I just better suited going with a X399M or Zenith Extreme  Alpha? Both seem to have good LN2 support, or am I really doing something wrong here.

Probably is a BIOS version thing and setup of volts. Which CPu are you using?

Tried both my 2950X and 2970WX. CB at -60C with any of the available public Bios’

I'd suggest to try going back to a bios version from around the launch, as sometimes things related to ln2 benching breaks later on and is usually not retested. Also the TR4 socket is problematic on ln2 and pins easily lose contact resulting in memory issues or worse. Slow mode does not help with cold issues. Do you get stuck at any specific post code when trying to boot at below -50?

The MEG just boot loops. The Zenith worked fine yesterday with its LN2 mode

Unfortunately I tried every single available public bios for the Creation and every single one had the same issues. Doesn’t get stuck on a particular post code and just loops. 

 

Simply enabling LN2 mode on the ZEA and ZERO issues for multiple hours
