I upgraded to the Ryzen 7000 series for the first time. Before assembling the full system, I tested it on an open bench. The motherboard CPU and RAM came from Ryans, while the rest used parts from my previous build. When it started up, there was no display output. The yellow debug light appeared, stayed active briefly, then turned off. After a short delay, it reappeared again while the fan spun and the RAM light stayed on, but the PC didn’t boot. I changed RAM sticks, slots, used a single stick, removed the CMOS battery and reinserted after ten minutes, shorted the JBAT1 pins for ten seconds, tried connecting a GPU, and even without any storage devices. Still no display and the yellow light kept flickering. Specs included a Ryzen 7600X, M.2 B650M motherboard, Corsair Vengeance 16GB x2 at 6000MHz, Antec HCG Extreme 1000W SSD, and a Transcend SATA SSD.
You waited several minutes before attempting to diagnose the boot issue. The AM5 boards often need time for memory initialization, sometimes taking multiple minutes. If after five minutes it still doesn’t boot and the RAM passes debug checks, consider it a problem. Otherwise, try updating the BIOS and retry (using bios flashback). The 7600x was supposed to be supported right from the start in 2022, so a BIOS update could help. Still, it’s not ideal. If you’ve updated the BIOS but nothing changes, a debug LED is lit—likely indicating RAM issues. The manual says the second LED from the top should show RAM problems. This suggests your RAM might be incompatible or faulty. Even though you seem to have the correct slot (DIMMA2), it’s possible the RAM itself needs a BIOS update for better compatibility. There’s also a chance the CPU socket pins related to RAM were damaged. Inspect carefully. If you purchased these, returning the RAM for a replacement after a BIOS update is advisable, ensuring it’s listed in memory support.
the cpu and the motherboard were working well together. i acquired it from a friend, but the bottom right sata slot failed during shipping. (the 2x sata slot is a bit sticking out from the rest of the board. the pcb and all other parts are fine. i assumed it wouldn't impact the mobo, but maybe not.) my ram is xmp certified. although i checked, xmp rams shouldn't exceed their rated speeds. i'm torn between the mobo's problem or the ram.
If the port encountered issues while shipping, it's possible another component was affected too. The best approach is to test both the RAM and the motherboard by swapping one part at a time. RAM seems like the simpler option, but updating the BIOS could also resolve compatibility problems that were fixed later.
