Consider upgrading your CPU to an I9-9900K model.
Consider upgrading your CPU to an I9-9900K model.
I understand your concerns about the motherboard compatibility. The board you have is compatible with I9-9900 non-K models. You might consider getting a K version later if needed for upgrades. Regarding I9-10900 and newer, it’s likely not supported by this board.
It could fail because of BIOS restrictions or the 9900K might not improve performance over a 9900K since it has a higher TDP and the motherboard can't supply enough power. The connectors are also incompatible.
Don't go that route. I wouldn't rely on that i9 in that setup.
