Motherboard [27/10/2024]ASRock DeskMini A/X300 BIOS /"P1.90.SL01"(S3 support) & "P1.91"(Curve Optimizer) for X300 /"P3.70E" for A300 - AGESA ComboV2 PI "1.2.0.Cc"

[Dr. Nick]

In the P1.90 bios, is there any cpu core voltage offset option (negative) in order to lower the temp a bit?

Besides Curve Optimizer I don't think so. You can lower the PPT manually though, which won't cost much performance, especially if you add 200 MHz via Boost Overdrive.
