I don't know a lot about intel motherboards. I need a cpu that will fit that is at least 2.6ghz. What do you recommend? It has to be an intel. I built a computer for a guy and his sign machine and it is not compatible with an amd chip. Help is needed fast.

Brief, practical guidance tied to this thread and the replies from , and .

The socket and chipset era involved (LGA‑775 / 915P) generally accept Prescott‑family Pentium 4 CPUs, but final compatibility is governed by the motherboard CPU support list and the BIOS microcode the board ships with. Flashing the board to the latest official BIOS before swapping processors reduces the chance of boot failures; also confirm the board's voltage regulation and cooler mounting are adequate, since Prescott CPUs run hotter than older cores.

On the Windows XP OEM question: a clean install is the most reliable outcome, which is why recommended reinstalling. There are less disruptive options—an XP "repair" (in‑place) install or a hardware‑independent restore/image (Sysprep or third‑party tools) can often preserve installed applications and settings while forcing Windows to redetect new chipset drivers. OEM licenses commonly trigger reactivation after a motherboard change; telephone activation usually resolves this, but having the product key and original media on hand is important.

Hyperthreading: it helps multi‑threaded and highly concurrent workloads and light multitasking; it rarely speeds strictly single‑threaded applications and has been known to expose bugs in old drivers or timing‑sensitive software. For a sign‑control application, test both HT on and off—if the control software or drivers behave oddly, disable HT.

Quick checklist (for archival readers encountering this later):

  • Image the system drive before any hardware swap.
  • Confirm CPU support on the motherboard CPU list and update BIOS first.
  • Verify heatsink/retention and adequate case airflow.
  • After swap, check BIOS settings (memory timings, disk mode) and install chipset drivers.
  • Be prepared to reactivate Windows (OEM restrictions) and keep driver installers and images archived for future reference.

This complements earlier replies while focusing on practical steps and risks to avoid when changing motherboard/CPU on an older LGA‑775 system.

Ok, now answer me this. I have to change the motherboard and the cpu because of incompatability with a piece of equipment it will be running. Will I have to uninstall the os and then reinstall. The only thing I will be changing is the mobod and cpu. I have an oem xp pro.

yes you will have to reinstall the os, and yes that cpu/mobo combo should work fairly good for you aswell. good luck on your build.

I have the oem xp pro. Will I have to contact microsoft for an activation key or should it work without it.

that depends, did you install it on a machine yet? if you did then your answer is you will probably have to contact them.

I went to Intel's own site for info on my AN430TX board, dating to the late 1990s! They still had VERY useful info on that motherboard that I needed, highly recommend doing a search there as well!

Do you recommend hypterthreading or not. I disabled it on my other machine but just want to know your thoughts.
