I aimed to replace my 16GB DDR4 with a larger 32GB DDR4 setup—specifically two 16GB Corsair Vengeance DDR4 3600MHz units. After installing them in slots A2 and B2, the system booted but the motherboard emitted a three-beep sequence and the DRAM debug LED began flashing. I experimented by rearranging the RAM positions, using just one stick, and even tried reinserting an older Crucial 8GB 2400MHz module, but nothing worked. I attempted a CMOS reset by short-circuiting JBAT and removing the battery, and inspected the CPU pins for damage. Despite these efforts, the PC still wouldn’t start and only beeped three times before shutting down. I also observed the CPU’s EZ Debug LED briefly lit up for about 0.1 seconds before switching to DRAM. Any advice would be greatly appreciated (PC: i9 9900k, MSI B365M Pro-VDH, RTX3060, 16GB Crucial Kit 2400MHz RAM).

Welcome to the forums! You did disconnect the power from the PSU as well, right? That means that the CPU is passing the POST and it's hanging on RAM. I assume when it shuts down it doesn't start booting again within 30 seconds, that would be the memory training process. This seems like it's a mobo problem, but I'm trying to eliminate other possibilities.

I took it off the power supply unit.

The motherboard (MSI B365M Pro-VDH) can handle DDR4 memory up to 2933 MHz, but overclocking via XMP might push it beyond this limit. Without XMP enabled, your Corsair Vengeance 3600MHz could exceed the board's capabilities. Make sure your BIOS is current for better compatibility with faster RAM. Some users have needed to lower the BIOS settings to fit higher-speed memory.
