CPU upgrade (hyperthreading issue)
Currently I have a P4 2.26GHz CPU, I'm about to upgrade to a P4 3.06 GHz
(with hyperthreading). Will I have to reinstall Windows XP in order to enable hyperthreading? I've heard a million different stories about this, but I'd like a definitive answer. |

CPU upgrade (hyperthreading issue)
You need a motherboard that supports hyperthreading, a CPU
that supports hyperthreading, an operating system (Windows XP-Home or Pro) and software applications that support hyperthreading. Intel has all the details on their web site. www.intel.com search for hyperthreading on homepage and these are the first of thousands of hits Searched for hyperthreading Results 1 - 10 of about 3,970 Search took 0.14 seconds.

CPU upgrade (hyperthreading issue)
Here is the simple answer:
If you are just replacing the P4 2.25GHz CPU with the 3.06GHz, then you might not have to re-install. However, you may not get HT working. If you have to replace the motherboard, when changing to the 3.06GHz, then YES, you will have to re-install. Also, if you have an OEM version of XP, then you will need to buy another copy of XP for the re-install. OEM versions are forever tied to the first motherboard/PC that the software gets installed onto. As per the End-User License Agreement (EULA), OEM versions can not be transferred.

CPU upgrade (hyperthreading issue)
Well, I just did this (moved from 2.06GHz to 3.2GHz 800fsb 1MB C2 cache),
but I had to change motherboards too (875 to 865 as the 875 did not support the 1MB cache). I did NOT have to reinstall the OS, but it was NOT an OEM install (it was installed from MSDN Universal). I DID have to reactivate though. My IBM laptop also went through a motherboard/CPU change with the same hard drive image and I just had to reregister. In this case it WAS an OEM install version (at least I think so). -- ____________________________________ William (Bill) Vaughn Author, Mentor, Consultant Microsoft MVP www.betav.com Please reply only to the newsgroup so that others can benefit.

CPU upgrade (hyperthreading issue)
Bill, I'm sure that you had to perform a repair install to set XP to the new
CPU / Mobo combination. This would also prompt for the re-activation process after installation was finished. Generally IBM and other laptops with their OEM versions of XP will not require activation [just part of the way their versions are configured]. It is impossible to use the installation CD on anything other than the same family of computer! In all cases REGISTRATION is not mandatory; only ACTIVATION is required when installing XP and other Microsoft products. Registration is where one provides their personal information across to Microsoft for the purposes of receiving support or written communications regarding the product. Activation is a part of the Microsoft copyright protection and anti piracy features. Once registered, as a user of course it isn't necessary to reregister every time one reinstalls Windows. Activation is to be expected each time Windows is installed [initial instance, a repair install or when a PC is rebuilt and Windows is loaded onto a clean hard drive etc..].

Laptops motherboard are unique and are mostly replaced by the manufacturer.
Then, the manufacturer may have the permission to "transfer" the OEM XP. "BAR" wrote in message ...
