Question about XMP support on AsRock A320m HDV 3.0
I've recently switched from a Ryzen 5 2400G to a brand new Ryzen 5 5600X, and I'm using an AsRock A320m HDV 3.0. I had to update the BIOS on the motherboard, and everything worked out smoothly. I usually rely on XMP settings, but with the previous CPU and BIOS, the RAM performed without problems. It maintained a stable speed of 3200Mhz at 1.35v for about a year.
After upgrading with XMP enabled, the system started crashing unexpectedly—powering off completely, even without any BSOD or errors. This happens during more intensive tasks like gaming or running Memtest86. The PC powers down after just a few seconds when memory is heavily used, and even at base speed, the RAM is functioning normally. All tests passed without issues, indicating the RAM isn't faulty.
I also ran stress tests on both the CPU and GPU, keeping them under full load. Temperatures were manageable despite using the stock AMD cooler. The PSU appears to be in good condition, as it handled the load without problems.
At this stage, I’m considering two possibilities: either the motherboard can't support it, or the memory controller on the CPU is the issue. The fact that the PC shuts down suggests the RAM might not be receiving enough voltage, even though I've pushed it to 1.45 for stability.
I've experimented with various RAM speeds and configurations, but it seems I can't exceed the base clock speed. There doesn’t seem to be any other BIOS update running on the system.
Components used:
- AMD Ryzen 5600X
- Palit NVidia GTX 1070 Dual
- 2x8 GB Corsair Vengeance LPX 3000MHz DDR4
- AsRock A320m HDV 3.0
- Corsair 650m 650W PSU 80+ Bronze
- Seagate BarraCuda 1 TB
- Internal HDD – 3.5 Inch SATA
- 500Gb SSD NVME M.2
Corsair represents the power supply brand, and 650W indicates the claimed power output. The specific model of the device remains unclear. Regarding your motherboard, please share the current BIOS version you're using.
Things to consider:
AMD boards list different QVLs for memory depending on the CPU. Your old RAM worked well with your previous CPU, but that doesn’t guarantee full compatibility with newer models.
The A320 is among the most affordable Ryzen motherboards, making it challenging to run the 5600X smoothly. I’d anticipate some issues may arise.
The issue could stem from the new CPU itself, especially if power consumption exceeds what the motherboard can handle. If you remove one RAM stick to lower power usage and see improvement, it might point to a motherboard concern rather than the CPU.
It's a CX 650m, roughly two years old, with the Bios version 7.10. They belong to the same set, but running it at 3000 causes crashes too—mostly any active XMP profile does. The CPU has passed stress tests with high load using Furmark and Cinebench, so it appears fine under those conditions. Ryzen might be a bit sensitive with memory settings, though I thought it would work considering it's a newer model. I don't believe the MOBO is broken, but it seems too fragile to handle the new 5600X; maybe trying an OC with Ryzen Master could help bypass the Bios and fix the problem.
Using a single stick of RAM in the correct slot should allow the system to function properly.
