Help with Asus Radeon 9600XT

[fruitless]

Hi.

I have an old motherboard, the ASUS A7V266-E.
Just recently purchased an ASUS Radeon 9600 XT from newegg for it.
Installed it and noticed that my computer used to frequently lock up. Installed the ASUS smart doctor utility and it mentioned that the VDDQ for the AGP card was not enough!

Turns out my card needs a VDDQ of 3.3 V but my motherboard manual mentions that the AGP slot is keyed in to work with 1.5V cards only. So was browsing the net for motherboards and saw the ASUS A7N8X deluxe at newegg. The manual for that one also mentions that it is keyed in to work with 1.5 V cards only.

I do not understand if the slot is keyed in to work at 1.5 V, how did a 3.3 V AGP card fit in it? Also what do you suggest I do? Return the card and ask for a 9600XT 1.5 V card? I do not know if these exist? OR am I doing something wrong here?

If most motherboards I check out have a 1.5 V AGP slot how did a 3.3V card fit in it? More importantly if the 9600XT is a 3.3 V card what motherboard does it work with? The strange part is that both of these are ASUS products.
Sorry pretty confused here and not sure what to to. As of now I reinstalled my Geforce 3 Ti 200 and it seems to be working fine so far.

Any help would be appreciated.

Thanks.

The A7N8X-DLX will work with a 9600 XT.

Hi.

Was wondering if my PS (350W) Antec is enough for my specs.
Currently I have removed the Radeon 9600 XT and have installed the Geforce 3 Ti 200 and all seems to be fine.
No lockups at all.

Also,
The CPU temperature threshold is 86 C/186 Farenheit.
The Motherboard temperature threshold is 60 C/140 Farenheit.

Current temperature readings are
The CPU temperature reads: 53 C/ 123 Farenheit.
The Motherboard temperature reads: 31 C/ 87 Farenheit.
I guess as these are within threshold and so should be fine.
I do not have anything overclocked.

The only strange thing seems to be the ASUS monitoring utility reporting that my cards (9600XT) AGPVDDQ is 1.5V, and should be 3.3V for correct operation.
I was running it at 4x with fastwrites disabled. My current motherboard supports AGP 4x.
Is my motherboard too old to support this card?

Thanks.
