For the porpouse of installing and testing Windows 11 I decided to sell my old 7770K and get a new 9900k (since they are both socket 1151) in order to extend the life cycle of all the rest of the hardware that so far worked good.
After removing the old and installing the new I have been getting a Red C in the panel, according to the manual it is cpu related, I have the latest published bios and should work, but it doesnt. Please help as soon as possible.
I made arrangements to send my old one to the buyer and I dont want to stay "offline" long
Thanks in advance and sorry if I left something out
