Question CPU Doesn't seem to be performing after installing in new build


Sep 29, 2012
Just replaced my motherboard and RAM and noticed that my performance and FPS in most games have dropped since the replacement. I have ran cinebench and TimeSpy and noticed that my CPU is getting a pretty low score (5200) and I wondered what the issue might be?

Unsure what the score was in my old PC, but games were running much smoother. CPU isn't OC'ed. I've set motherboard settings to default, temps aren't going higher than around 60c so I don't think it's a thermal issue. Task manager was saying CPU was only running at 2.8ghz during cinebench, but I thought it would be running higher as it was under load. Currently can't enable XMP with my new RAM as I'm getting an error. This motherboard only has 2 DIMM slots, so the configuration can't be wrong.

Not sure what else I can try. Would appreciate any ideas, thank you!

CPU - i5 12600k
RAM - Corsair Vengeance 32GB DDR5 RAM CL36 6400mhz (currently running at 4800)
Motherboard - MSI MPG Z790i EDGE Wifi motherboard

It looks like Intel Turbo Boost is disabled so your CPU is only running at the base frequency.

Try running ThrottleStop 9.6

Post screenshots of the main window, the TPL and FIVR windows. Delete any MSI control software that is running on your computer. Some MSI software is bugged. It can lower the turbo power limits which can disable turbo boost.

ThrottleStop should show the source of this problem.

Windows 10 or Windows 11? Did you do a clean install? What was your previous motherboard? Windows 10 does not properly support Intel 12th and 13th Gen CPUs.

Update CPU-Z

I've set motherboard settings to default
as far as i know that would be timed PL1-PL2 system which means itll only burst for a short while. Also besides the Throttlestop screenshot, mind telling us your cooling system? This means your cooler, case, and case fans layout.
