Well maybe this is happening because of the disassembly H it is the only reason I can think apart from as you say a mobo / CPU problem.
But the fact that it is giving this error doesn't affect the boot is good.
In the BIOS the CPU is listed I suppose an obvious statement but if it is then the CPU message should only be displayed once. All the power leads nice and snug?
Personally I think the CPU is fine and it is the mobo that may be having problems. Now that might show up when you run the RAM tests any problems there would certainly point the finger away from the CPU.
Don't suppose you have an old machine you could try the RAM in?
Look I am sorry this is dragging out a bit and it has to be something hardware based. Your BIOS is it the UEFI or not?
