Hi,

I'm using ASRock Z490 Extreme4 and i3-10100F CPU. I want to use base frequency boost but when i change it form auto to 125W, CPU still don't go higer than 55W.

I don't have the 4-pin ATX12V2 cable connected because my power supply is a bit old. Is this cable needed to use BFB?

I pluged in atx12x2 (bought molex to 4pin cable) but but still hitting only 55W. I changed base frequency boost in bios from auto to 125W. What am I doing wrong?
