Tomahawk b450 (non max version) cold boot issue

[SGardiner68]

Hi All

 

I am having an issue with my Tomahawk b450 MOBO.  

 

When starting from a cold boot the machine will simply not boot.  CPU error.  It may take dozens of power cycles before the maching will boot.

 

Once booted the operation is flawless.  I have run just about every stress test imaginable with no issues.

 

Getting the machine to boost is the issue.  So I typically let it run 24/7, which is not an issue in the winter.  In the summer my office gets kind of hot if it runs all of the time.

 

I am using bios  7CO2V19 (E7C02AMS.19) from July of 2019.

 

I have tried every new bios released since, which solve the cold boot issue.  However, none of these are stable with my setup.  Frequent BSOD's or random reboots occur. 

 

Any input would be appreciated.

 

Hardware:

MSI Tomahawk b450 (non max)

Ryzen 5 3500

G.Skill Memory 2 x 8 GB 3200

Gigabyte 1660 ti

Corsair RM550x PS

WD Black SN750 nVme
