My Ryzen 5 7600X is being severely power-limited on an MSI Pro B650-S WiFi motherboard. It should pull around 140W under load but maxes out at 95W in Prime95 and 74W in Cinebench.
Quick stats (HWiNFO64):
- Prime95: 95W, 68°C, PPT at 66%, EDC stuck at 45%
- Cinebench: 74W, 62°C, PPT at 51%. Scores: 11420 Multi-core, 1425 Single-core
- Temps are way too low (<69 C), not thermal throttling
- Performance scores are below expected
Already tried:
- Manual PBO limits (140W/95A/140A)
- Latest BIOS (official)
- Reset BIOS settings to default, enabled PBO and EXPO
The problem: EDC limit stuck at 45% suggests VRM/power delivery can't handle the 7600X's current draw, even though MSI lists this CPU as compatible. Clock is speed is always maxed to 4.45GHz
Has anyone successfully run a 7600X at full power on this board? Any suggestions?
