Intel i7 10800H downgrade i7 9750H/8750H

Good day Experts.

Recently i got msi laptop which had a Drmos melted on cpu vcore. i replaced that and the short is gone. laptop starts when pwrbtn is pressed but no display. Capslock not responding(no capslock led ever) so i assume cpu is just bad..

cpu is getting hot as normal. keyboard backlite works. all voltages are present and in normal range. cpu, gpu fans are spinning..


I want to replace it but i dont have i7 10800H, i have a donor i7 9750H and 8750H.. the question is any of the 2 i7 8th and 9th gen can work here if replaced with the bad i7 10800H..?? as per specs all 3 cpu has the same tdp, bga socket. only difference is cores and speed..

Thanks

Note the marking on each cpu,look for them in cpuworld website and find out the microcode for each of them. Then check your bios for microcode support.If the microcode is supported in your bios,it is likely to work.

You can look for microcode guidance here
