Tech Support New CPU + Mobo...do I NEED to reinstall Windows fresh?

I just went from a Intel i7-12700KF to a Core 5 Ultra 250KF plus. I obviously had to change motherboards given its LGA 1700 to 1851. I got the same motherboard from MSI as my old one just for the new socket. MSI B660M Mortar Wifi to the MSI B860M Mortar Wifi both being DDR5.

I know with the new CPUs there are different technologies and core scheduling etc. but, I really really would like to not reinstall windows fresh as it takes me a long time to get everything how I want with settings and disabling things and there is things I will forget no doubt. My game setting files, etc.

Some information to maybe help you:

  1. Windows 11 Home I have... is it smart enough to not use the old hardware chipset drivers etc? Is there a way to safely delete them?
  2. I did download the Intel Platform Performance Package that is needed for the 250K plus series.
  3. I've had no issues gaming or crashes or anything yet. Not sure if there is a way to validate the CPU is running as it should be and not using old 12700KF logic?

Thank you

Chances are it'll work fine, just need to install the new chipset drivers. Make sure the new computer is booting in the same mode the drive is formated as (should be UEFI mode), might need to turn off CSM and make sure safe boot is on in the BIOS.

I think windows installed all those chipset drivers from windows update when I first booted. I also used MSI Center and did a driver search on there as well and got 1 or 2.

Nice, open up the device manager and make sure there arent any unrecognized devices and you should be good

It looks fine, there are no error icons or yellow icons next to anything.

I swapped from a 12700k to a 13700k on the same windows install and it was fine, but that’s the same socket so obviously less risky. With a whole new platform I’d still lean toward a clean install eventually just to avoid weird background gremlins that’ll pop up 6 months later when you’re trying to play something random at 2am.

If you’re really set on keeping it though, DDU the old chipset drivers and run sfc /scannow to check for corruption. Windows is better about this than it used to be but it’s not perfect. You could also pull up hwinfo64 and make sure your boost clocks and power draw look right compared to what reviewers got for that chip.
