Gigabyte GA-H270N-WIFI BIOS - stuck at CPU fan on and off

@petersbc1402c Awesome! Enjoy your your new CPU! Thanks for reporting back that it was successful.

Hi all,
A final update on this thread. The system is working fine.
When I flash the backup BIOS IC, the system fail to boot. I had to reflash the main BIOS IC and the system boot again. Not sure why but I am going to let the issue rest.
Attached is the picture of the programming clips that I had tried. The blue and yellow types do not work. I use this fine tip clips because the backup BIOS IC is not accessible with the SOIC8 clip. Don’t waste your money on them(blue & yellow). The black clip works and do not press vertically down onto the motherboard in order to get better contact. Just open it wide and let the clip grab from the side. Pressing it down will cause the contacts to slide up and spoil the clip.

Just an update on this BIOS mod. I tried to upgrade to a 1TB M.2 NVME SSD by installing Windows 11 directly, but it won’t let me. The Windows 11 installer says the PC didn’t meet Windows 11 requirement even though PC Heathcheck says all Windows 11 criteria are met. I have to install Windows 10 and upgrade to Windows 11.

Do you know what was stopping the installation? I suspect either a TPM or Secure Boot issue.

I ran PCHealthcheck and all markers were green on Windows 10. I then booted into USB and ran Win 11 installation and the installer stopped due to not meeting Win 11 requirement. I am very sure about TPM 2.0 was turned on. Possible that Win 11 installer checks mobo chipset?

@petersbc1402c It doesn’t check the chipset AFAIK, but definitely the processor. It must be 8th Gen Intel or newer (except for some specific 7th Gen Surface models).

I have a 9350K running on a Z70 board with Windows 11 and TPM enabled (ME 11.7.0.1261).
