If the board supported say, low end Core 2 chips and you wanted to use a mid range core 2 chip then it may be possible but not adding support for a completely different generation of CPU's!
The only way forward looks like a new motherboard im afraid

Are you sure it is not possible?
Well, first, this forum seems to be the one that is dedicated to to bios modding, dont caring about if the board have full support or not, as this sub-forum is also dedicated to put CPU support in the motherboard.
If I just give-up this motherboard will be leaved in dust, and without use. I would like at least to try to push up this board to the limit.
So, in the case of my motherboard, for example, I know that this motherboard can run CPUs until models Pentium 4F [Pentium 4 662: 3,6 GHz, Pentium 4 672: 3,8 GHz], these are known as Prescott-2M, following this come Pentium 4 "Cedar Mill" that are all based on Prescott-2M... but "Cedar Mill" are newer...
Quote:Pentium 4F
Prescott-2M built on 0.09 µm (90 nm) process technology
2.8–3.8 GHz (model numbers 6x0)
Introduced February 20, 2005
Same features as Prescott with the addition of:-
2 MB cache
Intel 64bit
Enhanced Intel SpeedStep Technology (EIST)
Cedar Mill built on 0.065 µm (65 nm) process technology
3.0–3.6 (model numbers 6x1)
Introduced January 16, 2006
die shrink of Prescott-2M
Same features as Prescott-2M
As you can see, Cedar Mill cores could be considered a high-end if you compare with old Prescott-2M cores, because it is built in 65nm instead of 90nm, it have less problems with heat, and more...
Here, also another case...
Quote:Pentium D
Dual-core microprocessor
No Hyper-Threading
800(4x200) MHz front side bus
LGA 775 (Socket T)
Smithfield – 90 nm process technology (2.66–3.2 GHz)
Introduced May 26, 2005
2.66–3.2 GHz (model numbers 805–840)
Number of Transistors 230 million
1 MB x 2 (non-shared, 2 MB total) L2 cache
Cache coherency between cores requires communication over the FSB
Performance increase of 60% over similarly clocked Prescott
2.66 GHz (533 MHz FSB) Pentium D 805 introduced December 2005
Contains 2x Prescott dies in one package
Presler – 65 nm process technology (2.8–3.6 GHz)
Introduced January 16, 2006
2.8–3.6 GHz (model numbers 915–960)
Number of Transistors 376 million
2 MB x 2 (non-shared, 4 MB total) L2 cache
Contains 2x Cedar Mill [Prescott-2M] dies in one package
In this case, I could take the Pentium D Presler, that is dual-core, and is based on Cedar Mill, it seems to be compatible... and would be more easy to find to buy than the older P4 Prescott-2M.
Quote:Pentium Extreme Edition
Dual-core microprocessor
Enabled Hyper-Threading
800(4x200) MHz front side bus
Smithfield – 90 nm process technology (3.2 GHz)
Variants
Pentium 840 EE – 3.20 GHz (2 x 1 MB L2)
Presler – 65 nm process technology (3.46, 3.73)
2 MB x 2 (non-shared, 4 MB total) L2 cache
Variants
Pentium 955 EE – 3.46 GHz, 1066 MHz front side bus
Pentium 965 EE – 3.73 GHz, 1066 MHz front side bus
Here, another case of compatible models... not considering the ones with 1066 MHz FSB, that could gave problems because Asus P5GD2 have the limit of 800Mhz, IMO.
There is also some Core 2 Duo and Quad that have a 800Mhz FSB, but I am not sure about the compatibility.
About the power requirements, well, I think it is not a problem, right? Because newer CPUs are all prepared to use lower voltages, and lower watts, so I would only need to lower the voltage in the BIOS, and/or mod the BIOS to unlock voltage capabilities, and get a good air cooling. :-)
It also would be cool if I do benchmarks of different CPUs in the same motherboard... and see how much one Cedar Mill core is better than Prescott, or, how much a Pentium D is better than P4, or a Core 2 Duo is better than Pentium D and P4. It is because, comparing CPU architectures in different motherboards with different memory bandwidths, or different memories, it is a dirt comparative to me, it will not give a good and solid data about different CPU performances.
Thank you and Best Regards.
