Random Cold Boot Issue on Ryzen

[zipp]

Hi guys, I have recently built a new system and I'm having an issue which I am having a hard time getting to the bottom of, so I am hoping someone here can help me with some advice.

 

I have the following system:

 

Asrock x370 Taichi

Ryzen 1700

G.skill Flare x 3200 memory

Crucial MX300 SSD 1tb

MSI 1070 Armor

Thermalright Le Grand Macho RT cooler

EVGA G2 650w PSU

 

 

The problem is that sometimes (very rarely) I receive an error code "0C" on my motherboard.  When this occurs, it is always on a cold boot.  The most recent time this happened was today and I turned off the system with the power button, started it up again and it booted with no problem.  It hasn't occurred before today for a couple of weeks.

 

I have been overclocking and I currently have the system running at 3.7 ghz @1.275v.  Since first getting the error (3.8 ghz @ 1.3v, RAM with xmp 3200), I have been slowly increasing the voltage and cpu speed up and leaving the RAM on default (auto).  According to the debug code, it looks like a RAM issue.  I've ran memtest 86 and that was all OK, Prime95 is OK as well.  I am on the latest bios version.

 

Do you think I should RMA the RAM? I haven't built many systems, so I've never had to do that before.

 

Or do you think I should run more tests so I can get some hard evidence that it is the RAM that is causing the issue?

Not great with troubleshooting things like this but I would say its safe to assume it has something to do with the RAM. Have you tried adjusting the RAM speeds both up and down to see if there's any correlation?

I get this every now and then on a cold boot I loop and reset to default and have to dial my clocks in again

i think it's a ryzen issue on the latest bioses 

i have a hero 6 on the beta bios

 

so I assume it will get sorted in future bioses 

 

mine to passed men test and prime and aida64 but sometimes on a cold boot it fails then I dial in oc from bios and it boots straight away

I am pretty convinced it's the new agesa code doing something the ram doesn't like on a cold boot

maybe give the IMC more voltage?
