Bought i9 13900F and im stuck at 2,0ghz.

I have an MSI mag tomahawk b760 ddr5. And it says that CPU oc is unsupported. Am i stuck at 2,0 ghz forever. And is it slow?

 

MSI bios

Hmmm. CPU OC isn't supported on B-boards, RAM OC is though. It looks like it has the VRMs to run a 13900, and they have heatsinks so the VRMs shouldn't be overheating, so that won't be what's throttling the chip. What are you using to check clocks with? HWiNFO64 is the best monitoring tool, CPU-Z if you want to check just the current clocks, most other tools are occasionally inaccurate (especially Task Manager and HWMonitor, which I see lots of people use). What are you running that has it stuck at 2.0GHz, or does it just sit there no matter what load it's under or when it's at idle?

I just used the MSI bios to check the clocks. Would you say that 2,0 ghz is good on the chip? 

 

At 2,0 when idle. But in bios it says that the chip is 2,0 ghz

Hope the writing isnt to awful. Using a work pad

Oh that sounds normal, I'd actually expect it to run lower at idle, probably is when in the OS. That's expected behavior for a CPU with all the power saving settings still enabled (and there's no reason to disable them unless you need to). If you hit it with Cinebench or some other heavy load, you should see it spike up to the proper boost clock. The number Intel gives is for single-core max turbo, by default Cinebench is an all-core workload so you should see a clock ~300Mhz lower than what Intel says the max turbo is. For an inconsistent load like gaming, you'll often see clockspeeds bounce around.

Some motherboards disable Intel Turbo Boost when you are in the BIOS. The base frequency of a 13900F is 2.0 GHz so your CPU is running at the correct speed.

When you are in Windows and the CPU is loaded, it should be running a lot faster than 2.0 GHz.

 

Increase the turbo power limits in the BIOS so you can maintain maximum performance.
