OEM BIOS support is often limited to ONLY the CPU(s) sold with your PC i.e. as an option and ALL of the other CPU(s) will not have the CPUID to properly run the CPU.

You will have to contact HP and request a specific list of supported CPU(s).

I did see the following - https://h10057.www1.hp.com/ecomcat/hpcatalog/specs/provisioner/05/DG061A.htm
Intel Celeron with 400-MHz, 128KB L2 cache ranging from 2.0 to 2.4-GHz
Intel Pentium 4 with 533-MHz, 512KB L2 cache ranging from 2.4 to 3.06-GHz
Intel Pentium 4 with 800-MHz, 512KB L2 cache with HyperThread ranging from 2.4C to 3-GHz

You listed:
Intel® Pentium® 4 Processor supporting HT Technology 3.20 GHz, 1M Cache, 800 MHz FSB

The listed limit was up to 3.0GHz and not your...

If this is not enough let me explain it a bit more. I know this is pretty old motherboard and CPU, but...

Right now I'm using Intel Pentium 4 2.66GHz/512k/533 and I got this new CPU 3.20GHz from a friend. Tried to replace them and got error message 1801 Microcode update needed because processor stepping was incorrect for this new CPU. So I found my CPU stepping in BIOS and it was E0 and BIOS version was v1.11. I've flashed my BIOS and now it's version v2.44 and it supports CPU stepping for F26, F27 and F29 and I was sure that my problem will be solved, but...After I updated my BIOS it shows that my old CPU works at F29 CPU stepping and the new one needs F41, now I'm trying to find a latest BIOS version for my motherboard and that's why I asked for CPU support. Am I wasting my time or not? I have overheating problem with new CPU and CPUID shows only 1 core and 1 thread and this CPU have 1 core, 2 threads because it's 2HT.

Here's my BIOS info if it helps:

I hope so there is someone who understands this mess and who is willing to help a NOOB (me)!!!

-Thanks-
