PC Processors

[igeligel]

Hey y'all,

Soooo, after setting up a PC for my mom, everything was running fine for the first hours. Problems occurred after some time and I need help somehow because I am out of answers. I hope someone here can help:

The build:

• PSU: 400 Watt be quiet! Pure Power 11 Non-Modular 80+ Gold
• Mainboard: ASRock B450 Steel Legend AMD B450 So.AM4 Dual Channel DDR4 ATX Retail
• CPU: AMD Ryzen 5 3400G 4x 3.70GHz So.AM4 BOX 
• 16GB G.Skill Aegis DDR4-3200 DIMM CL16 Dual Kit
• Some Samsung SSD

So random Blue Screens appeared when using the machine. I posted here on Microsoft forums to get some help. Tips did not help though. So figured it might be no software problem but a hardware one (sadface).

The RAM was slotted in on A2/B2 slots on the motherboard which seems to be fine for the Pinnacle CPU series: [Source]. I run the RAM at default MHz and timings so nothing should have changed. Even did a reset of the BIOS settings.

So what I did recently is to test the memory with memtest86. First one RAM module on slot A2. This worked without errors, so I figured I let my mom work on the PC. 6 hours of work done on a day without any complaints/BSOD. Never happened before. Great thing.

The other day I tried memtest86 for one RAM module on B2. No errors. I did run the tests with the default configuration and via bootable stick.

Now the weird part: I ran memtest86 now again with both RAM sticks inserted on A2/B2 and it errored. Can show the logs tomorrow but does anyone has an idea? I have the feeling the CPU is the culprit (memory management of the unit) and needs to be resent, unfortunately. But wanted to ask first if there could be any fixes regarding BIOS settings that might help. Hopefully, someone could help. Cheers

Is XMP enabled in your BIOS?

I had the same kind of stability problems with my PC (3400G and 2x8GB 3600 MHz RAM) until I enabled XMP and ran the RAM at 3200 MHz.

Tried that, unfortunately, did not help.

It is possible that RAM you have installed for the Pinnacle Processsor is not 100% compatible with the 3500g APU.

That is why it ran fine with just one RAM stick but when you installed both it started crashing.

I see that ASRock doesn't have a RAM QVL List for Picasso so I guess the Raven Ridge QVL Iist is the closest one since that is for APUs.

I went to G-Skill RAM CONFIGURATOR for your Motherboard and I don't see any DDR4 3200 Mhz RAM modules listed for your Motherboard: https://www.asrock.com/mb/amd/b450%20steel%20legend/index.asp#MemoryRR

I suggest you open a ASRock Support ticket to see if the RAM you have is compatible with your Motherboard and Ryzen APU.

EDIT: If you ran MEMTEST86 separately on each RAM Stick in different DIMM Slots and it came back without error  but you ran both together and came back with error could indicate a faulty Motherboard or CPU.

Either way I would open a ASRock Support ticket and see what they suggest.
