We need to know which motherboard you have. There is a model labeled on the board. It is usually somewhere around the memory modules and CPU.
The socket is 478 which does help. But there was 3 different base clock which may have created 2 limitation within the socket.
- 400Mhz motherboards does not support 533 or 800 CPUs
- 533MHz motherboards does not support 800 CPUs
- 800MHz motherboards will support all frequencies.
And even then there could be OEM limitations. If the motherboard BIOS needs to be updated. Hopefully an updated BIOS can still be found on the Internet. That is if one was ever released by the motherboard maker.
I tried looking at the text on the CPU but it was not readable. That would have given a little detail as to the compatibility of the socket.
