I would like to identify if my processors are compatible and if my CPU is compatible with my motherboard. The specification of my motherboard is PT800CE-A. When I boot my computer, it is displaying Pentium 4 and I think that would be related to the single core hyper threading at 3.0 GHz.
If you can successfully boot your computer, then it means that the processors that you have on the computer are compatible with your motherboard even if they are Pentium 4. In case they were incompatible, then the computer will not even load. What you should be concerned about is the speed that your computer is going to operate at. Since the processor is not from the same manufacturer as the motherboard, the speed at which the computer operates may be tremendously slow, and therefore you will need to check that out. In case it happens to be that way, then you will need to get a processor that is from the same manufacturer as the motherboard.
Here’s a fact: if your processor is not compatible with your motherboard, the computer will not run. This is because if the processor is not compatible with the motherboard and you boot your computer, most of the time, the CPU will automatically shut down because of overheating even if there is a CPU cooling fan installed. This is one sign that the processor is not compatible with the motherboard.
If you plan on upgrading your processor, you need to verify the supported socket number or socket model of the motherboard. You can find it printed or engraved in the processor socket or CPU socket, the part on the motherboard where the processor is installed.
Examples of processor sockets or socket models are Socket 478 (mPGA478B) for Intel Pentium 4 processor, Socket AM2+ for AMD Athlon 64 processor, LGA 775 for Intel Core 2 Quad processor, and more.
