PC Processors

I'm using a Ryzen 7600X on a Gigabyte b650m s2h motherboard. It's been about a month and my CPU is consistently getting low results on Cinebench. Games stutter often times (My GPU is RX 7800 XT). I also monitor the temperatures on HWInfo and the CPU hardly ever reaches 60 degrees during benchmark, which should go as high as 95 afaik. It runs on 75 watts and my motherboard doesn't allow any overclocking/PBO so I cannot change the PPT. There is one thing I suspect, the power supply connection. I wonder if I open the case and look if the power supply is connected with 4 pins or 8 pins, would that change anything? If not, is there anything I can do to increase my CPU performance? I'm especially confused with the temperatures. I recently bought a decent cooler to go with the CPU (Thermalright Phantom Spirit 120 SE) but I don't think it would be able to cool it down to 60 degrees. It was running barely hotter before while I was using it with a placeholder crap fan anyway. Here is a Cinebench result with HWMonitor.

The B650 chipset allows for PBO control.

Here's the link to your Gigabyte B650 motherboard BIOS manual. The AMD Overclocking menu can be found under Advanced Mode, Settings tab. (page 13)

I'm afraid this one, Gigabyte B650M s2h, doesn't allow PBO. I changed PPT several times but the motherboard doesn't honor the changes I make. When I run Ryzen Master it warns me that overclocking is disabled for this motherboard. The settings are there in the UEFI, I enter AMD OC in BIOS and accept the warning message, yet whatever I change doesn't apply.

Is this a prebuilt PC, there are makers that lock out OC functions to protect their warranty.

Yes, it is a pre-built PC, but I've seen similar complaints on the Internet several times that this motherboard is OC locked, so I'm not sure. Anyway I was able to fix it by downgrading the BIOS version. Version F30 seems to be working fine (though it still doesn't allow OC or PBO) CPU runs at 120 watts, hits around 85 degrees and Cinebench score is up to more than 14800.
