System starts up but fails to display output.
Motherboard model: ASUS B850m Max Gaming Wifi (BIOS v2.22.1284)
CPU: Ryzen 7 9800X3D
RAM: Trident Z5 Neo RGB 2x64
GPU: Radeon RX 7900XTX Sapphire Nitro+
Power Supply: Corsair SF1000 SFX Full Modular 1000W
Storage: Samsung 9100 Pro 4TB 14800 mb/s
CPU Cooler: Arctic Liquid Freezer III Pro 240
OS: Not installed; currently booting into a working build with Trident Z5 Neo RGB 2x16, and the 2x64 RAM functioned in an earlier configuration.
Troubleshooting attempts: Referenced forum advice about post issues and memory restore settings, but no success. Blink codes appear on power button—uncertain meaning.
Check compatibility with a 1x64 stick. If not, explore alternative channels. Occasionally it only works with one stick.
You also had to wait a considerable amount of time with memory training on the 2x64GB system. A 128GB RAM setup is quite substantial for consumer boards. The 7800x3D and 2x16GB configuration on the PC I assembled for my sister required only about 5 to 10 minutes for a full memory training session the first time around.
We haven't tested any alternative channels. We used only A2 for single sticks and both A2 and B2 for both. We changed the position of the sticks in the slots and also tried swapping them individually. Let the device operate for at least an hour without any outcome.
In short: You've tested both options. The 2x64 functions on a known working machine but not on the Problem PC, while the 2x16 works there. The 2x64 fails on the Problem PC in any channel and when run alone. That matches what you're observing.
