Question PC shuts down completely during Prime95 ram test

[kenj1ng]

I just upgraded my cpu from r3 3200g to r5 5600 on a A320m motherboard. I have 2x 8gb ddr4 3200mhz memory (Kingston fury)

On default bios setting (3200)
Dual channel the pc starts but no input
Single stick i'm able to get into windows and ram test runs fine(ran it for 3 mins then stop it, idk it could run for longer or not, but it doesn't shut down)

With manual Underclock, the PC runs fine
But when i try Prime 95 "memory controller & ram" torture test
I set to 2800 dual channel, it runs 20sec then shutdown
2666 runs for 30sec
2400 runs for a minute
2133 runs for 3 minute

Here's the full spec :
mobo : Asrock a320m-hdv r4.0
CPU : Ryzen 5 5600
RAM : 2x 8gb Kingston Hyperx fury 3200mhz
GPU : Rx 560xt /rx 470d ( it only used 75w)
PSU : MSI a650bn
1 sata ssd (128gb) & 1 nvme ssd (500gb)
1 harddisk

I ran other torture/stress tests like the cpu and gpu it doesn't cause shutdowns

You will need elaborate on this.

mobo : Asrock a320m-hdv r4.0
BIOS version for your motherboard?

I have 2x 8gb ddr4 3200mhz memory (Kingston fury)
Did you purchase them at the same time or did you get them a few months apart?

PSU : MSI a650bn
How old is the PSU in your build?

Would recommend a bios update to the latest version to improve memory compatibility. It may help solve this instability issue.

The gpu is a Aisurix RX 560XT, there's not much info but it basically a bios updated rx470d

The Bios ver was 7.20 with AGESA 1.2.0.7

I got the ram for like a 1&1/2 year ago before i got the cpu and gpu. The whole pc was a 3200g prebuilt.
Back then with the old cheap korean PSU i can run the pc with 2999mhz speed. It never shutdown when gaming i never ran a stress test that time

I just bought the MSI PSU today, because i have this issue for about a week ago right after the cpu upgrade. It happens when i try to play cs2
It runs fine for 30min then it shutdown midgame.
After that i try to Underclock the ram & disable CPU boost clock. It didn't shutdown when gaming & the pc was stable

Then I try to compile shaders on a Unreal Engine project that i have, It shuts down again . I then lower my ram again just to finish the compiling. Then i run some ram test. It still shutdown itself

Hey there,

TBH, I wouldn't be running Prime or any torture test with an A320 mobo. They have weak VRM's are not meant to be pushed like that. Why are you using Prime?

For the game crashes. Something is not stable. Take off the undervolt and or any other OC's you have going and run at stock.

As suggested, make sure you have a new bios, as older ones won't support your CPU. You must also clear CMOS after the bios update.

According to Asrock website my ryzen 5000 was already supported since 7.1, I updated the bios to 7.2 ever since i have this issue.
Im thinking i should update to L8.01 with the AGESA 1.2.0.8 since the latest ver 10 is on beta that might cause more issues.

But right now with my ram underclocked to 2133mhz and CPU boost clock (PBO) turned OFF, The PC runs fine gaming and all.

Can you suggest other way to test my system stability other than using Prime?

I understand now the main issue is my motherboard's VRM
because with my old 3200g it only go for 3.8Ghz , but 5600 go for 4.4Ghz so i have to turn PBO Off.

also if reset my bios to auto settings it will set my ram to 3200mhz 1.2v cl22. and it will just not boot to windows. The PC just starts but no input (just black screen) like it's a ram problem, so i have to take 1 stick out and manually underclock the ram to anything under 2993mhz just to boot to windows, then shut it down & put the ram back.
