12900f

Hi all, I have a new PC with a 12900F i9 CPU. I think its bottlenecking the system at the moment as I cant get it to go anywhere near its turbo boost frequency of 5.1Ghz, it lingers around 2.4-3.4Ghz. This chip is new and is watercooled by a 360mm MSI AIO. Any help getting the CPU to run...
