First though: why on earth pair a V5-5500 with a Prescott?

They're hardly from the same period, and if you don't care about that, why not go for a Northwood, which:
- is at least as fast as Prescott
- runs cooler
- has far wider choice of motherboards when it comes to AGP

But if you really want to team the two up, you need a Prescott-supporting So478 board with universal AGP, so 4x (2.0). It's the chipset that determines the AGP version, so you'll want something from Intel i845 or i850 series, SiS 645 or 650, Via P4X266, ALi Aladdin-P4 or ATi RS2xx - and then find a board with one of those, 3.3V AGP and Prescott support. That's going to be a challenge, as these are 2000-2002 era chipsets and Prescott wasn't launched until 2004... a quick check of Asus and MSI support sites shows that their flagship models with the latest of these chipsets don't do Prescott (BIOS limitation and probably TDP too).

Asrock is the only manufacturer with multiple boards that will do stuff like this, take a look here:
https://www.asrock.com/mb/SiS/GE%20PRO-M2/index.asp#CPU
https://www.asrock.com/mb/VIA/M266A%20R3.0/index.asp#CPU
(note: 2.4GHz Prescott is supported, 3.06GHz not, almost certainly due to TDP)
(also note: Asrock's Intel 845x chipset boards do AGP 4x, but only at 1.5V, so no V5 possible)

Too problematic. Easier to get Athlon XP 3000+ with KT333.
Alternatively you can just buy AGP-to-PCI adapter and use any Pentium 4 board you like.

Yes. Some motherboards with the SiS 651 chipset support Socket 478 Prescott P4 CPUs and AGP 2X. (You don't want just AGP 4X or AGP 1.5V support. Only acquire a motherboard if its manufacturer states that it supports AGP 2X, Universal AGP or AGP 3.3V and its AGP slot has no key.)

And when you've acquired this motherboard, first test it with a cheap AGP 2X card with no 1.5V notch (such as a RIVA TNT or a Rage XL) before you put an expensive Voodoo 5 AGP in it.

thx for your detailed answer.

reason = because I've gotten these 2 procs for free and would love to build a powerful V5 machine... 😉

it's that simple.

but finding the right mobo isn't...

Well, since it's about having gotten the CPUs for free, you have to factor everything in...

For example, if you could get "the right mobo" for this setup for $200, or as an alternative you can get a different mobo for, say, $100 and a compatible CPU for another $10, which would make your build easier / more stable - what would be the better choice? 😉

Indeed, you can get Northwood CPUs for (near) free as well, and AthlonXPs too. Both would be a far easier, more natural choice for the V5, cheaper too as you can take pretty much any universal motherboard, and it's unlikely the Prescott would be faster.

and it's unlikely the Prescott would be faster.

It's more or less on par or slightly slower, when it comes to old software and games that Voodoo 5 can handle.

I really want find the Northwood p4 1.4A. TDP is only 38 W.

I don't know about Prescott, but the later revision of the abit sa7 supports the Hyper threading and the voodoo5500 and 533mhz fsb CPUs

What about a Socket 478 Northwood Pentium 4-M? Is there a way for them to work in any desktop motherboard?

Asus CT-479 adapter.

Downclock Pentium 4 2800/800 to 400Mhz bus and drop voltage below 1.45v (1.1-1.2v if your motherboard can allow it). TDP below 30w should be possible.

IIRC the mobiles are locked to the lowest multiplier and there is no way to change it = slow and useless... as AGP 3.3V boards are not very good at overclocking.

As far as I know only works on few selected Asus i865 / 875 and later boards. Also it is meant to run Pentium M on desktop board, not Pentium 4-M.
