Temporary swapping a CPU to a lower-end one.

Recommended Posts

Posted · Original PosterOP

My problem is simple: I need to temporary swap a CPU, and then put it back after I finish doing what I wanted to do. Can anyone provide steps for swapping CPUs, like: clearing CMOS, cleaning thermal paste and etc.?

Really all you have to do is pull the CPU cooler, clean the thermal paste off the CPU and the heatink (easier to clean the CPU while its still in the mobo, so just do it then), pull CPU out, put new CPU in, add thermal paste, remount CPU cooler, boot PC. When it boots, the mobo will likely throw a "New CPU detected, F12 to enter BIOS". Just enter BIOS, then you can exit the BIOS (you shouldn't need to adjust any settings), and it'll work!

 

Then do all that again to put the original back in.

 

Just to make sure, you are planning to put a CPU that works in, right? What CPU do you have now and what do you plan to swap in?

Yeah, i have a mobo that has an outdated bios, (dont ask me how it got outdated) therefore it doesnt have microcode for my 9900K. I have Celeron G4900 which my motherboard supports, and im gonna swap my 9900k to boot into my pc and then update my bios so i can run my 9900k again.

Here is a link to my motherboards cpu list: https://www.asus.com/Motherboards/ROG-MAXIMUS-XI-HERO/HelpDesk_CPU/ Right now my motherboard's BIOS version is 602, and 9900k started working on it only since the 1005 came out lol

Was it working before..? I guess I am just confused what happened here.

 

But.. yes, doing what you said would work. Just, how did you get there? lol. Did you have the G4900 in, swap to the 9900k, and not update the BIOS first?

Yes, exactly that. G4900 was my temporary CPU.
