Built a pc for the parents last week using cobbled together spare pc parts.

Ryzen 3700x (Was in my pc for the last few years)
MSI B450M-A PRO MAX (bought new)
Corsair Vengeance LPX 16GB 3600 C18 (bought new)
Kolink Modular Power 500W 80 Plus Bronze Modular Power Supply (new)
970 Evo 500Gb ssd

I set the ram to the DOCP profile and things seemed OK. However that day after setting the pc up the computer spontaneously rebooted.

Bad sign. I decided to stress test the pc by downloading Cinebench 24 and it was OK for the 10 min multi core test and has been fine for the last two weeks.

However this evening it has spontaneously rebooted again. :(

My hunch is the ram. I have set it to its default speed of 2667 rather than the docp profile of 3600.

Suppose we hope for the best.

:eek: kolink psu's dont have a very good rap tbh, are you using a dedicated gpu in the build and if so what gpu are you running?
I would strongly advise looking over your psu first, you would mostly likley need a 650-750w psu depending on what gpu you have. look at something else than kolink too.

Only running a Nvidia 710.

This pc is just used as an office pc. No gaming.

For now I have turned off the docp profile on the ram hopefully that's the issue.

If it isn't then it will be the PSU.

Ok, so in the event view I see some of the following errors:

Event 18 WHEA-Logger

Reported by Processor Core
Machine Check Exception
Cache Hierachy Error

---

And another similar tothe one above but
Bus/interconnect Error

A quick google of the error and I find this.

Whats a coincidence is the ram they are talking about in these posts is a Corsair C18 kit (mine isnt rgb though)

Are you still getting these with XMP/DOCP disabled?

It is a pretty common error (or it was when Zen 2 was released) and it means the CPU is unstable.

Turning off C-States or increasing the minimum CPU voltage (through a positive curve) fixed it for some people, but many of these CPUs had to go back.

I know that LPX had issues with Ryzen, but afaik that was mainly the older LPX kits, not the newer "Ryzen optimised" ones. It can be tested relatively cheaply with some crappy used 4/8GB 2133/2400 stick

The cpu was in my gaming rig for a few years then moved to one of my workstations for another year or two and now given to my parents. Nothing wrong with the cpu.

My bet is it is the ram.

Every Corsair ram kit I have owned on Ryzen since 2017 I have always had issues with. But this stuff is meant to be optimized for Ryzen...

Corsair Vengeance LPX 16GB (1 x 16GB) DDR4 3600 (PC4-28800) C18 Optimized for AMD Ryzen - Black

I have since turned off the docp profile and hopefully that's the end of it.

However the pc is not turned on often and only has sporadic use so don't know yet if that made any difference.

I am still within the return window however I dont have the packaging any more.

So it seems turning off the docp profile on the ram seems to have sorted it.

Shame as I paid for higher speed ram than I am getting. But it's a pc used by the parents as a workstation so not a big problem.

So far my experience with crucial ram has been very negative.

I bought crucial when I bought my 1700 back in 2017 and that was a nightmare and now with the 3700x more crucial ram is not working properly.

The ram says "optimized for Ryzen" as well.

It's not the imc on the CPU as I ran this with 3600Mhz in another configuration.
