I'm facing some frustrating issues after upgrading my setup, and I could use some guidance. I recently swapped my processor from a Ryzen 3 1200 to a Ryzen 5 5600, using the ASRock B450M-HDV R4 motherboard, which is a budget option without VRM heatsinks. Since the upgrade, my PC has been experiencing hard shutdowns under load, accompanied by "Critical Error: Kernel-Power 41 (63)" in Event Viewer, indicating unexpected power loss.
My current build includes:
- GPU: Sapphire Nitro + RX 6700 XT
- RAM: 2 x 8GB at 2666MHz
- Cooler: Stock AMD Wraith Stealth
- PSU: 650W MSI MAG Gold
- BIOS version: P10.10
I've tried a few troubleshooting methods:
1. OC'ing my RAM to 2933MHz made things worse, causing shutdowns even during memory tests.
2. Increasing all fan speeds helped a bit, but the system still shuts down during gaming.
3. I attempted a PBO Curve adjustment but saw no improvement.
4. The only stable setup I found was to disable "Core Performance Boost" and keep the RAM at stock settings.
I suspect the VRMs might be overheating since there are no heatsinks on them, and pushing RAM voltage could be stressing them.
I have a few questions:
1. Does the "Kernel-Power 41" error point towards VRM thermal issues?
2. Would adding generic aluminum heatsinks to the MOSFETs help if I keep the 5600 at stock settings?
3. Should I consider just running the CPU at 3.5GHz until I can get a better motherboard?

It sounds like you're really pushing that budget motherboard to its limits! The ASRock B450M-HDV R4 isn't ideal for the Ryzen 5 5600, especially without good VRM cooling. That Kernel-Power 41 error definitely points towards an issue with power delivery, possibly overheating VRMs. I’d recommend getting some VRM heatsinks. Even basic ones can help dissipate heat and might stabilize your system.
Honestly, if you’re running it at 3.5GHz and it’s stable, that’s not a bad deal for now while you save up for a more robust motherboard. Just keep an eye on temperatures and performance until you can upgrade!
Yeah, I agree. It can make a difference. And if it still shuts down after that, it might be time for a better motherboard to handle that 5600 properly.
