CPU upgrade Will it work on this MOBO

[navyfalcon]

Motherboard Specifications, P4SD-LA (Stingray)
original processor
• Processor type Intel® Pentium® 4 processor 530
Clock Speed 3.0GHz
CPU Socket Type Socket 478/N, Socket N
Multi-Core Technology Single-Core
TDP 84 W
Chipset 'North Bridge' 865G
Chipset 'South Bridge' ICH5
• Intel Pentium 4 runs at 3.0 GHz internally and 800 MHz externally

Processor upgrade: upgrade
Intel Pentium 4 CPU Processor 3.4 GHz 800 MHz Socket 478/N SL793/SL7KV (550/551)
Key Features
Clock Speed 3.4GHz
CPU Socket Type Socket 478/N, Socket N
Multi-Core Technology Single-Core
TDP 89 W
• Supports DDR 266/333/400 SDRAM
• Memory capacities 128-, 256-, 512-, or 1-GB non-ECC
• Maximum memory 4 GB
• Chipset Intel 848P (Breeds Hill)

I know the system is old (more ancient), but I want to do the upgrade. Faster upgrades are 115w TDP. The original processor is 84W TDP and I think arctic silver thermal paste will make up some of the difference and lapping the CPU cooler (not the CPU) will make up some more of the difference.
Any information and suggestions would be appreciated.
Thank You

It only support up to 3.2 GHz P4 Northwood.
It will not work.

What is the limiting factor ??

It is listed as a Northwood
I am not questioning your answer, I just do not understand.

What is the limiting factor ??

It is motherboard / chipset limitation.
https://en.wikipedia.org/wiki/Pentium_4
Northwood 2.4 GHz, 2.6 GHz and 2.8 GHz variants were released on May 21, 2003. A 3.2 GHz variant was launched on June 23, 2003 and the final 3.4 GHz version arrived on February 2, 2004.

Northwood can go up to 3.4 GHz
Prescott can go up to 3.80 GHz

The limitation here is the motherboard as it only support Northwood CPU up to 3.2 GHz.
This is a limitation made by the motherboard manufacturer.
