i recently got a Socket478 main board and i've put a Pentium 4 1.7Ghz on it, with 512mb of DDR266.

Now, the AGP slot seem to be AGP 4X/2X, and it doesn't have any key inside.

I want to know if my upcoming V5500 AGP would work just fine in it? or i could damage it?

The board in question is a DFI PM12-TL, product number "PM1201-3", Rev.A.

ok so i'll check for an Athlon XP board, i may know someone who could give one to me.

Would it be worth upgrading this Slot-1 up to 1Ghz instead of 800Mhz?

FSB is 100Mhz, not 133Mhz...but i heard FSB100 are better at overclocking than 133Mhz ones.

SiS 645DX is a P4 chipset that support agp2x/3.3V without any problems. I had a while ago Asus P4S533 and it worked with a V3 3000 card and it worked very good, I played online Warcraft 3 on it.

I'm 99.9% sure that VIA also made such chipsets.

That doesn't mean that I recommend the use of those chipsets, in my opinion a system equipped with a 3dfx card should have a motherboard that was available at that time, maybe a little newer, but not by much.

For example V2 cards should be used in a BX440 motherboard, V5 cards used with I810/815 motherboards, etc.

I really don't understand peoples that use V2 cards (or even earlier cards) on the latest motherboards (sometime even in Windows 7/8...

What's the point? To see how good the latest game (patched to work on V2) works ob a V2. It will run like crap and it will also look like crap.

This is not true.
There are several board for Pentium4 in the 533MHz quad-pumped FSB range that are compatible. The best chipset on which you can bet is the SiS645 (SiS645DX is better). Although it offcially supports AGP 3.3V out of the box, the actual compatibility is at the discretion of the manufacturer (not all the board were designed to give 3.3V on the AGP slot).

Cannot find much on the DFI PM12-TL aside from the manual here: ftp://download.svoa.co.th/Drivers/SVOA_PC/Computer/DFI/PM12-TC/Manual/PM12-TL.PD... which about expansions slots states the following:

Quote:


This does not mean the board is necessarily incompatible but does not even mean it is compatible. More likely the board does AGP 2x @1.5V instead of 3.3V if you ask me.

This DFI has the ViA VT8751 northbridge: http://www.via.com.tw/en/products/chipsets/p4-series/p4m266/

Again, nothing states clearly if the NB provide the needed voltage or not. In the whitepapers I found this quote:

Quote:


But if it does even mean that the NB supports 3.3V on the AGP bus, this not necessarily suggests that the board is compatible; it depends if DFI chose to implement this feature in the board design.

The best advise I can do is to try first a known 3.3V VGA, a Voodoo3 for example, and see if it works or not.

Nope.
The truth is that nobody knows exactly what could happen if you try to use a Voodoo5 on a 1.5V AGP platform, since different users reported different experiences (but definitely, none of them was a working solution).

Personally I remember that if you use a Voodoo5 into 1.5V AGP slot you will get only the first VSA to work, like a Voodoo4. But this it's just my experience, others may have experienced other results or could be ended with dead cards. So caution is preferred.

I agree,  a KT333 is definitely better, since Voodoo5, speaking of performance, likes more high FSB (166MHz on AMD Vs 133Mhz on intel - 200MHz bus intel platform are all AGP 3.0 so they are out of question).

i tried the DFI board here, it have 2x 256mb DDR PC2700 in it, but due to the board, they run at PC2100 maximum.

I also tried an older AGP card in it, which is keyed for AGP 1x/2x only, so 3.3v operation (ATI Rage 128 GL, L-shaped card with a tiny heatsink on the GPU) and it seem to work. I can select "2x" in the AGP option as well in the BIOS, but it's selected automatically i think.

Because right now instead of trying to upgrade my P3 boards to 1.1Ghz up to 1.4Ghz, i could use this P4 board which seem to be compatible with AGP 2x cards as well.

So do you think this Pentium 4 1.7Ghz board (DFI PM12-TL) would be the best for my Voodoo5 5500 AGP?

i do have a board with an Athlon XP 2500+ on it. Problem: it's too new: Asus A7N8X, AGP 8x with AGP Pro feature keyed for AGP 8x/4x only...maybe the 4500 would work on it since it have both keys (last card released), but not the 5500.

Funny thing though: the board only take 20pins ATX, no 4-pins ATX12V, yet it have many extra features

Someone is supposed to get me another Athlon XP board, maybe it'll have the KT333 chipset on it.
