So I solved the problem, I have no freezes unless I run the computer for about 24 hours or so.

What I did was lower my DRAM voltage to 1.1v at 2133 MHz, and also increase the VDDP to 1.15. Both of these can be changed in 'OC tweaker' in the BIOS.

The DRAM voltage does seem low, but it has basically solved my problem as freezes are no longer a major issue. If 1.1v is unstable or you want a higher speed, you can probably try increasing the VDDP along with the DRAM voltage.

Since the problem was fixed by messing around with RAM voltages, the problem probably lies somewhere with the RAM and/or the PSU.

well yes, chips perform worse (and thus need more voltage) when they're hot.
once the computer has been running for a while and heated up, the stock voltage may suddenly not be enough.
increasing the voltage a bit can help keep it stable even with the increased temperature.

of course i'm just speculating, it could also be the memory controller, you could try raising SoC to 1.1v.
but i had a similar problem with a RAM overclock becoming unstable with increased ambient temps.

I've taken out each stick of RAM and have had the computer freeze with just one stick plugged in. And why would the RAM work fine for two hours and then suddenly freeze the computer regardless of what programs I'm using? 

Doesn't the 1-2 hour countdown to freeze indicate it has to be some type of temperature related issue? The computer freezes much faster if I immediately reboot after a freeze.

i wouldn't go over 1.35v vcore, 1.1v SoC, or 1.4v DRAM voltage.

it sounds like a ram issue IMO, i had similar issues while i was figuring out my overclock. ryzen sometimes has problems with ram even at stock settings.

if you're running stock, DRAM voltage should be 1.20v by default, try bumping it to 1.30v ~ 1.35v.
don't touch anything else, shouldn't need it if you're not overclocking.

it's possible you may need to adjust ram timings, i don't know if that kit has an XMP profile, but XMP settings usually are not well optimized for ryzen. i would expect it to be fine at stock though, so save that as a last resort.

it's also possible you just got bad ram. if you have any other ram laying around that you can swap it out for just to help narrow down the problem, that might be a good idea.

Plugged my own computer?™s PSU into the freezing computer and it froze again.

Uggghhhh... temps look good... not sure what to do. CPU or MOBO issues???

I?™ve seen some of you suggesting adjustments to voltage... how do I do that safely?

A new MSI B350M Gaming Pro has been ordered. Not a huge selection of M-ATX boards at my local dealer.


Attaboy! Clap

I usually use my 12ga shotgun for skeet shooting bad electronics/stuff I hate. LOL No kidding. Someone behind me throws it in the air and I shoot it. Feeling is priceless!

Hope you have more luck with the MSI as they are not particularly known for great products. Please do come back and do tell us how it went with the new mobo.

OMG. That's bad, mkay!

TBH, these new PCIe retention mechanisms prove to be troublesome for many.

Now it's a chance to grab a Taichi! Thumbs Up

Oh well. In the process of trying to remove my GPU to access the CMOS battery I tore of the PCI Express port. Damn you securing mechanism ! Thats a first for me Cry 

On to the online supplier to order a new motherboard.

I also started swing hard freezes on my B350M Win10 build the last couple of weeks. What I have done so far:

Clocked down Ryzen 1200 to default
Update BIOS to 3.3 from 3.1
Update AMD chipset drivers and power plan
Set memory voldtage to 1.35
Set VDDP to 1.1

Next set of action is CMOS clear.
