You won't be able to make a 1Ghz CPU work on that system board. Its too old of a board. The LH3000 supported a 1Ghz CPU.<BR /><BR />Ciao,<BR />Greg Wed, 07 Aug 2002 15:02:16 GMT Greg Carlson 2002-08-07T15:02:16Z https://community.hpe.com/t5/netservers/hp-netserver-lh3-processor/m-p/2781515#M3114 I've been delegated the task to upgrade our HP netserver processor. We have the 1GHz PentiumIII's and just to test I put one in a card slot and had the other terminated. The POST message is showing that the processor is a Pentium Pro 700Mhz. It also comes up with a Missing Microcode error message. I have the most recent Bios and I was wondering if there was an unwritten setting on the speed switched that would enable the processor to operate at full speed. Or is there any way to get a Bios update from PhoenixBios that is compatible with the motherboard? I appreciate any clues to what can be done here.
