I bought a motherboard from eBay, marked as "for parts/not working, no display".

Motherboard: Asus TUF B650-Plus WiFi

CPU: AMD Ryzen 5 7600X 6-Core AM5 (w/ integrated graphics)

Memory: Kingston FURY Beast RGB 8GBx1 6000MT/s DDR5 CL30 | KF560C30BBEA-8

TEST 1: Installed CPU w/ cooler, and 1x8GB Kingston RAM

Result: No display, DRAM Light on

TEST 2: moved single RAM around to each dimm slot, and waited \~5 minutes for memory training

RESULT: No display, DRAM Light on

Further Troubleshooting:

\- Checked socket pins, everything looks perfect

\- Used thermal camera to check for obvious shorts: apart from the CPU, the inductor chokes marked "R10" were the warmest components, reaching the high 70's Celsius. However, I believe this is expected due to memory training

\- used a multimeter on the VRMs, and they all looked good

\- Updated BIOS to latest version as of May 2nd, 2026

\- No obvious signs of damage to the MoBo or it's components

\- I cleared CMOS

\- I also tried 2x 16GB sticks of Corsair vengeance RGB 5200MT/s in multiple locations, still no luck

Additional note: The CPU power takes an 8+4 ATX cable. I've just been using only the 8 pin cable, because when I add the additional +4 pin connector, the board shows no signs of activity. Wondering if I should revisit using 8+4...

I bought a motherboard from eBay, marked as "for parts/not working, no display".

Initial Test: Installed CPU w/ cooler, and 1x8GB Kingston RAM

Result: No display, DRAM Light on

Next Test: moved single RAM around to each dimm slot, and waited ~5 minutes for memory training

Result: No display, DRAM Light on

Further Troubleshooting:

- Checked socket pins, everything looks perfect

- Used thermal camera to check for obvious shorts: apart from the CPU, the inductor chokes marked "R10" were the warmest components, reaching the high 70's Celsius. However, I believe this is expected due to memory training

- No obvious signs of damage to the MoBo or it's components

Still no display, and still the DRAM Light is on.

Any ideas?
