P4 2.6 ghz running at half speed

Wait until OP returns.
HT is not the issue at this point.
Computer is:  Gateway ESSEX2 desktop computer

Well that's interesting...
Maybe it's the Hyper Threading that's doing it? Try turning off Hyper Threading inside the BIOS settings? It could be that the motherboard doesn't support Hyper Threading technology... If we had a Name and Make of the motherboard we may be able to tell if it has the support for hyper threading....

Computer Commando, Help me with this?

Is the info you want?

BIOS UPGRADE, THAT MIGHT SUPPORT THE HYPER THREADING.

Possibly end of problems? (I hope)

I have downloaded the upgrade, will work on the problem tomorrow as it is getting late here.  I will be replying on progress again tomorrow.
I really appreciate everyone for there help and my thanks to them.

You are very welcome.

Glad to be of service

I see 2 Northwood Socket 478's at 2.60GHz
RK80532PC064512; BX80532PC2600D, 400MHz, 26;  This P4 would give you 2.6GHz
RK80532PG064512; BX80532PG2600D, 800MHz, 13  This is probably your P4; part number is on the top of the cpu

Your Bus Speed is 100, Celeron's multiplier is 26, P4 multiplier is 13.

It's a lot more involved than you were thinking (LOL).  There's nothing you can do unless the motherboard has the ability to be reconfigured, which most all branded computers cannot.  Retail motherboards are much more configurable.

I am convinced that you are right, I installed a Celeron
2.66 ghz with bus speed 133.3 and multiplier is 20 with
core 1 and thread 1, computer would not boot up with that
processor, I also followed Merlyn's suggestions,
same thing no change.

Dang?... Well have you tried completely removing the CPU and checking that the TGA (Top Grid Array) Hasn't been swapped over... (indents on the CPU chip would indicate) Otherwise... I am stumped... I will do more research and see if i can help you...

  I've had the CPU in and out but don't understand what "TGA being swapped over" means!

Your cpu is a Socket 478 model, so you can just ignore that.

Please ignore my last post >.<(cold is getting to my head )

The specifications of this:
http://support.gateway.com/s/MOTHERBD/INTEL/2519056/2519056sp28.shtml
indicate that this CPU will work.
RK80532PC064512; BX80532PC2600D, 400MHz, 26;  This P4 would give you 2.6GHz
However, don't expect a significant increase in performance over the Celeron you are currently using.  Better to sell the Gateway than try to upgrade it.

Thank you Computer_Commando for post #27
The P4 is an extra CPU with more cache and higher bus speed than the celeron that I had laying idle and decided to install it in the Gateway PC that I dug out of the throw away bin where I live and don't intend to invest in upgrade for it.  PC runs good with the celeron also runs ok with P4 at half speed.  I would still like to solve the problem with the P4.

...I would still like to solve the problem with the P4...

OK.  A science experiment!  I don't believe it's a solvable problem.  The motherboard that is supplied to Gateway has a very limited number of hardware variations.  If you can determine make & model of motherboard, you may be able to find someone who has "hacked the BIOS" successfully.  There is a chance that the mobo is supplied to several manufacturers that each have their own BIOS.  I have a computer in a similar situation but am not willing to flash the BIOS as an experiment.
