I'm bulding a computer for my grand mother with some of my old hardware..the mobo is an old :p ASUS A7N8X-DX. When I read the user manuel there's a WARNING about installing only 1.5 V AGP card and no 3.3V ones.

The problem is I plan to install an old VIPER V770 and I can't seem to find the voltage of that card anywhere on the net...

Any help? I don't wanna blow the mobo or the card...

RAGE is of the same generation of carde so if the voltage is not correct for the tnt2 I doubt it will be for a rage.

Ok here is the problem with some of the TNT2 based cards, Even though they are keyed so they fit in a 4x slot they are 3.3v only. I think it was because they hit the market before 4x AGP chipset based boards were available and some card makers actually used PCBs that were only compliant with the older spec which meant they didn't do 1.5v? I had a TNT2 that was 4x 3.3v only, iirc it is the same model you have. I know it was 3.3v only because I tested it in my SN45G which had a protection feature against it and sure enough the red LED came on indicating it wasn't compatible and the system of course wouldn't boot with it.

Here is a link that warns about the problem Text
Another part of evolution of VGA card is its so-called "Gold Finger". 4x is the spec which is most usual used now. In picture one, there are three sets of Gold Finger, all supporting AGP 1.5V only. In Picture three, there are two sets of Golden Finger, all supporting AGP 3.3V only. However, in picture two, there are three sets of Golden Finger, supporting not only AGP 2x but also 4x. It is because of its character of not easy being identified as 1.5V or 3.3V VGA card, so this kind of VGA card is usually regarded as the murderer of motherboard.
So if that board doesn't feature protection against it, no way would I put it in there. You could either buy a used G2 or Radeon for it, or trade/sell the board for a very cheap model with IGP.

Okay if I understand your link correctly my card seems to be Universal AGP, but to be on the safe side, if I put it in and the card IS not compatible, will it blow the mobo? I dont really care for the card, but the mobo...yes.

Edit: Just saw DAPUNISHER post...so I guest the answer is yes..it will blow the mobo...danm....

I couldn't find anything skimming the .pdf manual just now that would indicate it features any protection against 3.3v cards so you could ask about it in the official thread for that board by searching for it.

If it is 3.3v only and the board doesn't have any protection then it can fry the AGP slot or maybe even the whole board. It is possible if you put it in and have voice reporter enabled it will tell you the system failed the VGA test. I wouldn't risk it though, not worth potentially nuking a good board like that over a $5 vid card.
