Use code 78 for DRAM amber or yellow illumination
Hello, I am trying to finish my build but keep running into some issues with the system stuck on ACPI Initialization (code 78). Spec Details - Motherboard - Asus Pro WS WRX80E CPU - AMD Threadripper Pro 5955WX GPU - A2000, RTX 2070, RTX 3070 RAM - 1. 32GB kit - Sk Hynix 16 GB 2Rx8 PC4-3200AA -RE2-12 2. 128GB kit - Crucial 16 GB DDR4-3200 UDIMM 1.2 V CL 22 BIOS - Version 1201 2023/06/07 PSU - Asus ROG Thor 1200 Watts OS - no OS (haven’t decided) Details on the issue - Then CPU was harnessed from a Lenovo P620 in working condition with the Sk Hynix kit. The motherboard in the current system has been replaced since the initial purchase had an error code ‘C0’ which has no reference in the manual nor Asus support had a clue. Got a replacement and now run into POST code ‘78’ (ACPI Initialization) with the DRAM amber/yellow led ‘ON’. Troubleshooting steps thus far - 1. Reseated the RAM 2. Reseated the CPU 3. Re wired the cables 4. Tried different RAM configurations in different slots (yes the same pairs of sticks) 5. Re flashed the BIOS with no errors (no way to tell as the instructions for flashback mention of the BLUE led on the IO blinks and then goes out indicating success) 6. Reset BIOS (CMOS clear) 7. Tried all the GPU’s I had (not in pairs obviously) 8. Going to swap the CPU and Sk Hynix RAM back to the Lenovo P620 to check if I haven’t damaged anything in the swap process Anybody has any idea on how to get this resolved?
Please review the board again. It might be another issue, possibly an MSI Z77 I bought faulty and stuck at code 63. Cleaning didn’t help, suggesting a chipset problem. If it doesn’t respond to overclocking attempts like 78 or 55, it likely isn’t working properly. Any code you don’t expect from a failed overclock could mean the motherboard is defective.
Thanks for the response. I’ll process this return again. To confirm, I haven’t overclocked or underclocked anything—just swapped to a new board.
