I updated to 1805 last night but only booted to Windows, haven't used my computer for anything yet.  I'll edit this post once I do.

However, so far it has done better than 1804 did, it booted right into Windows the first time, which is a plus.

When I compare the two settings files for 1804 and 1805, I noticed that these settings were removed with 1805:

- Selection Rules [Deterministic based on Worst Margins]
DIMM Fit Store [None]
Run DIMM Fit Pro [Disabled]
- Selection Rules [Deterministic based on Worst Margins]
Fail to next [Disabled]
DIMM Fit Pro Loops [1]

These options are no longer available? 

CPU SOC Voltage 
CPU VDDIO / MC Voltage 

[RyanBlakeIT]

They are not available to set according to the settings files.

There goes my IF oc. Without SOC voltage option wouldn't it cause problems for expo? 

[RyanBlakeIT]

My guess is it is set behind the scenes like it was with previous BIOS versions. You should be fine. No issues with EXPO being enabled for me.

Those are DIMM Fit / DIMM Fit Pro parameters, they will not show in menu / settings txt until you are using DRAM OC, see my posts on OCN.

Happy to see frequent bios updates for the X870E.

It would be nice if there were a fan RPM limit at boot, but there is currently no way to do this. A boot limit for each fan in Q-Fan would be ideal so that fan noise can be minimized until the full fan curve is loaded.

Bios is stable for me with a 9950X3D (undervolted), RTX 5070, and 2x 48gb 6000mhz DDR5 (CMK96GX5M2B6000Z30).

BIOS 1805 got me weird issues. Pbo runs extremely hot and co -15 gives me Instant aida64 failure.

Tried some CMOS and reflash but its realy weird right now.

Im confused and dont know what to so.
