AGP4X 1.5V

[NightTrain]

I've been reading up the last coupla days and cannot get a firm answer on exactly how to determine whether or not a video card is AGP4X ie 1.5v. I have a Geforce256 that I want to put in an 845 chipset motherboard without killing both of them. I've tested the A2 pin and it appears to be grounded...my multimeter displays the same continuity with A2 as it does with the mounting bracket which I assume is ground. The card has the 1.5v slot and when I boot it in a BX board, the video card bios screen says AGP4X but in Win98SE, it says AGP2X.

Any information that would help is greatly appreciated.

All AGP 4x cards are 1.5 Volts, such as a GF 256, TNT2, etc... so, install it without problems.

Do you have any idea what the oldest 1.5v card is? TNT2? TNT?

from what i recall the video card is definately 4x (As it says in boot up), but the BX chipset only supported up to 2x, so that is why Win98SE is stating that.


Now with that said, i have a question of my own....

Is there any concern in installing a 4x and or a 2x card in a 8x slot, especially due to voltage? i.e. 3.3V (?)/1.5V/0.8V I hear misleading info about it and im to lazy to search....

Video cards are backward compatible, meaning they'll run on older AGP slots. However, AGP slots are not forward compatible, meaning they will not run with newer AGP cards.

All GeForce series cards and all Radeon series cards support at least AGP4X, 1.5V.

An easy way to check if a card supports AGP 4X/1.5V is to look at the card's connectors. AGP 4X and above cards have two notches on the bottom; AGP 1X and 2X cards have a single notch (like the Voodoo 3).

Hmm....I didn't realise the Geforce256 cards were AGP 4x?
