i'm troubleshooting this gaming desktop for someone and I don't understand why the cpu voltages aren't showing up when it is powered on. i've changed the cpu, the motherboard and the psu. The LEDs are always on DRAM. I've swapped the four pieces of ram around and still nothing. Wouldn't the cpu voltages show up even without ram?

this coil is the only one in the row with a voltage reading. the rest have no voltage

Probably some of the VRM's is faulty, before VCORE is going ON, VCCSA and VCCIO must be provided. Look for VRM's having ENABLE active, but producing no power. Another reason can be faulty power sequence logic or faulty Bios image or even partially faulty SIO or PCH. Look for a power sequence diagram, and diagnoze where the power sequence is interrupted. The power sequence can be from a similar mobo same vendor, they are usually very similarLast edited by DynaxSC; 04-10-2024, 08:20 PM.Comment

Hi, I’m looking for a clean, working BIOS .bin dump (16MB) for the ASRock B450M Steel Legend motherboard.
I’ve already tried flashing the official ASRock ROM file via CH341A, but it won’t post — I believe the capsule format is incompatible.
Any BIOS version that supports Ryzen 5 2600 is fine (e.g., P2.30–P3.60).
If anyone has a working board and can dump the BIOS using CH341A or flashrom, I would really appreciate your help.
Thank you! -
Hello, could you help me with the boardview of an ASrock X670E Steel Legend? I have a project to assemble a PC from scrap parts. My last purchase was this motherboard and I want to try to repair it as much as possible. Any help is acceptable and welcome. Always grateful for the help Greetings -
Hi Guys,
I am new in electronics repairing. Do anyone have Asrock b550m steel legend schematic and boardview if can with front and back layer file?. Thank you in advance guys!...03-21-2025, 05:44 PM -
I've got an ASRock B450 Steel Legend that I'm trying to diagnose for no reaction to the power button.
The SIO receives the PWRBTN# signal and sends PSOUT#, but the CPU doesn't return SLP_S3# so nothing further happens. I have been looking around the board trying to figure out why and I happened to touch the STEP-DOWN CONVERTER NB685GQ-Z (UP10 in photo) which was VERY hot (like burn your finger). This seems to provide VDDP_S5, and indirectly, VDDCR_SOC_S5, which the CPU needs in order to handle the startup signals.
The VCC voltage powering the converter does not look right.... -
Kindly share boardview of ASRock X570 Steel Legend!!12-30-2024, 10:16 AM
