GeForce 4: AGP 1.5V or AGP3.3V ?

It runs in AGP 4x mode and has universal AGP connector. I think I bought it somewhere end 2002, if not beginning 2003, if that helps. It's a gainward.

I'm not really any good at anything electrical, but this article on "How to Volt-mod your GeForce 4" seems to imply that voltage varies from card to card within the GF4 range. So we're likely going to need to know if you have an MX or Ti and the model number.

Otherwise, it does seem to state that a Gainward Ti4200 has a 1.65v startup voltage and despite some mention of numbers around 3, seems to stick to the 1.<something> voltages for discussion otherwise.

Most probably it's 1.xV. The last 3.3V AGP card I've seen is my 3dfx Voodoo 3 with a whopping amount of 16MBs of VRAM. 8-)

I think he refers to the voltage of the AGP bus.

http://www.falconfly.de/identify-3dfx.htm said:

All Banshee, Voodoo3 and Voodoo5 AGP Cards are 2xAGP 3.3V only!
Do not use in modern 4x/8x AGP 1.5V only Motherboards!
Failure to comply can cause damage to both the Card and the Motherboard!
Consult your Motherboard manual for 2xAGP 3.3V support before use!

Only the retail 3dfx built Voodoo4 4500 AGP is 4xAGP 1.5V capable.
(the Powercolor Evilking Voodoo4 and the rare 3dfx Voodoo4 4500 "L" Shaped variants are confirmed to be 2xAGP 3.3V only)

The paragraphs above talk about 3dfx Voodoo cards, but it seems like that AGP buses up to 2x probably use 3.3V while 4x and up use 1.5V voltage.

Corelian is right.
AGP 4x == 1.5v

Derezo, Corelian: okay, thanks, that's what I wanted to know.

Cookies for you. And it's a Ti 4200 btw.

I still don't understand the question. I know and understand the answer but I don't know what you were asking. EDIT: Aaaah, I geddit now. You didn't know if you could stick the old gfx card into a new motherboard. :-[

maybe I should have been more explicit, something like:
Does the GeForce 4 use 1.5 Volt AGP bus or 3.3 Volt AGP bus..

anyway, glad you understand it now ;D
