Hello all. I have an old 386DX-33 system with all original equipment in it but I wanted to upgrade to 40 MHz so I bought an AM386DX/DXL-40 chip and swapped it. The swap went fine, computer turned on no problem but at the POST screen it identified the cpu is a 80386 with no suffixes (just like before) so I could not tell from the screen that anything had changed. I put a diagnostic util on a floppy and ran it and it reported back that the cpu was running at 16 MHz. Then I went into the BIOS, found that it was set up to boot in slow speed mode so I changed that and checked the speed again... 33 MHz. Why isn't it running at 40 MHz? Did I do something wrong or is there I step I have yet to do? My mobo is this one:
