Hello,

I have the B450M-HDV. The problem I noticed is that if I installed two sticks of RAM, then after playing games for 15-60 minutes, the exact minutes varies but is guaranteed it will happen, the PC completely freezes and monitor displays no signal. If I pushed the reset button and started the game again, it will immediately freezes within 1-2 minutes. I can only play for longer periods again if I let the PC turned off for a couple hours or more, but it's still gonna be 15-60 minutes at most.

But if I only installed one stick of RAM, no matter which stick and which slot, I can play for however long I can without any trouble, just tested playing for 5 hours no rest.

I have tried to MemTest86 both sticks, one at a time, on each slots (so total 4 times of testing), and at 4 passes, they resulted no error at all.

What could possibly be the problem? Ryzen 3400G no graphic card, RAM VGEN 2x8GB 3333Mhz XMP default CL16 (it still freezes even if I don't enable XMP and running at 2400Mhz). Could it be BIOS problem and I need to downgrade? Running 3.70 out of the box and already installed chipset driver from AMD.

Are you using slots A2 and B2 when using both sticks?
You can also try and see if using slots A1 and A2 (this will be single channel)
results in the same freezing.

Unfortunately my motherboard only has 2 RAM slots.

are you able to try a different matching pair of RAM? .. have you tried manually setting timings and make sure voltage is at least 1.35v? (Set to XMP, reboot and check memory timings .. then set memory to auto and select whatever the timings XMP where and voltage to 1.35v. If still problems, dial back the settings and/or up the voltage to 1.37v or so and see if that helps) You could have mismatched memory so they conflict with each other .. or because the memory controller is on the CPU, you could have a dud 3400g chip .. or .. bad mother board ... or maybe it's a power supply issue. Hard to say without replacing individual components and testing of which can be really hard to do because not everyone just happens to have a bunch of ram, other CPU's or power supplies just laying around ..

if BIOS 3.70 .. you must have the B450M-HDV R4.0?

What are you running for a PSU?

Hmm I'm trying to troubleshoot without getting another individual components. I will do that eventually, if I still can't find the problem with software diagnostic or my own tinkering, but due to where I lived it would take weeks to get replacement parts by mail, so for now, I'm just thinking I would do this first.

Except PSU, I already ruled that out since I already changed the PSU to another one (brand is Simbad, a no name brand, borrowed from a friend, it works fine in his PC, and my PSU as well) and the problem persists, now I'm using my own again (Corsair CX-650).

Indeed it's the R4.0 version, apologize for forgetting mentioned it.

RAM, motherboard, and CPU, can't get my hands on them for now, AM4 and DDR4 isn't the common parts here, small village and all.

Will try the manual voltage settings. I've never tried them since my RAM are 2 sticks in a kit, can't imagine they would be mismatched, but I have tried with XMP enabled, also disabled and running at default 2400Mhz, still freezing.

Hello brother, welcome to ram MANUAL tuning to match it properly to your CPU.

Were you ever able to resolve this£ I have the exact same issue.

I have... It's the motherboard problem, if I rolled back to earlier BIOS before V3.7, then it's fine, but there's a very noticeable performance degradation (minus 10~20% fps).
