PC not utilizing all ram

[CksToxiczombie]

MSI MPG x570 plus mother board

64 GB DDR 4 Ram installed (only utilizing 31.9)

Ryzen 5 2600 CPU

GTX 770 Graphics card

2 TB Hard Drive

Windows 11 PRO OS

 

 

 

Computer is not using all the ram, I have updated to the most recent Bios version.

The Ram however is two different versions. One set is version 5.32 the other is 4.33 would this make a difference?

Is it detecting all of the RAM? or just not utilizing it all?

Yes, that means that the first kit is Hynix CJR and the second kit is Samsung D die. Not sure how compatible they are with each other, Samsung D die isn't really that common of a memory chip to find outside of OEM sticks, but it could theoretically cause issues. 

 

Are both kits being detected in the BIOS? When mixing memory like this, a lot of the time you have to try a lot of different combinations of sticks in different slots and see what works. Lets call the v4.33 kit D and the 5.32 kit C. Try them in slots CCDD, CDDC, CDCD, etc.

Both were reading in bios but now it will only post with the 4.33 kit

Weird. Hynix CJR is usually pretty compatible with Ryzen systems, that kit should be just fine. I've seen memory kits just randomly die, but it's pretty rare. 

 

Both reading in the BIOS but only detecting half isn't super uncommon, usually it requires a memory reseat, leaving the CMOS battery out for a few minutes, and testing stuff in different memory slots.

I have reseated the ram I followed the mother board recommendations and they all four have booted again. I actually disconnected the hard drive and Graphics card. Now I'm gonna try and hook them back up and see if it posts.

Okay, good luck out there. RAM is a bit tricky to get through because even if a tiny dust short two of the RAM slot pins will render your whole system un-bootable. Imagine people's surprise that all it takes for me is to blow out the RAM slots with an hand pump and viola, the system is good as new.
