3. Once the system boots up  it only works for a few hours then hangs
   1. The longest this system ran is 4 hours with no load

Update to Situation: 

Ran Memtest86 for 4 Pass, before I was only doing 1 pass. This was done using Mestest86 boot USB and not from within Windows. Observation

1. Pass 1: No Error
2. Pass 2: No Errors, but at 36% mark for Pass 2 system froze 

Total time the system stayed up was close to 1 hour and 30 minutes

akshaykalia_chd, the long boot time is probably memory training not some fabric problem. Look in your Event Viewer and post a few Critical errors, Details Tab. Are there any errors for your boot device? Do a Clear CMOS and make sure all AMD drivers were downloaded here. What happens when it hangs? Mouse work, KB work, how are they attached? I would suggest you install W11 on a partition on your SATA drive and see if all is well. John.

EDIT: Try a single stick of memory.

I have eliminated windows to be an Issue already. Here is why it is not Windows issue.

1.  I worked for Microsoft for about 4 years out of my 20 years of my IT experience.  Further, I have done enough debugging within windows to be 100% sure it not windows.  
2. Memtest86 Boot from USB hangs at 1 hour 30 min into a test every time. I have tested with various RAM frequencies until now I have not found the one that can pass this mark. 1 hour 30 min happens to be Pass-2. 

Boot off a Single stick is something I need to test. Will post the result soon. 

Since Memtest86 Boot from USB hangs at 1 hour 30 min it can not be Windows, or System disk or a Driver etc. It is some Firmware config issue or my mem sticks have busted VRMs which only break after some continues use.

Look like I have same issue as 

https://community.amd.com/t5/pc-processors/ryzen-9-7950x-4-sticks-of-ram-issues-128gb/m-p/702029 but on 9950x with x870e chipset

Update: 

1. 1 on the memory sticks could not pass memtest86 
2. Look like stick has a VRM issue as it failed in Pass-3 right about 1 hour 30 min mark

System is working stable with 2 sticks of Ram. 

Have sent the RAM kit for replacement.
