AGP 8X card in 2X slot

[Koharski]

I'm trying to breathe some life into my lame PC. I'm upgrading to three hundres something megs of ram, and to a 1.5 or 1.4 ghz celeron. I want to put in a geforce 5200 (for the pixel shader) in my AGP 2X slot. Is this possible? I know that AGP 2X is like 5V, I don't want to blow anything up.

AGP 8x is backwards compatible with 4x, but not with a 2x slot. The voltage is differant, so it would most likely damage the card.

 

[Koharski]

hmm.. is 4x backward compatible with 2x?

 

[AllGamer]

it's not so much as the 8x/4x or whatever

it's the VOLTAGE level

8x and 4x runs at lower volts than 2x and 1x AGP cards.

basically if you put a 4x/8x AGP 2.0 card into one of those AGP 1.0 slots (1x/2x) you'll mostlikely end up damaging the AGP 2.0 card

it happend to me once

if you are lucky the card will be fine, but you wont be able to use more than 640x480 else you get reboot all the time

ah, okay. thanks. Whats the best card you can get in an AGP 1.0 slot?

WHat about that? Can I get a GF5200 with a universal slot like that?

Probably a Voodoo 3 or something like that.

But I think you can get a Geforce 6200 (or even something better maybe) in PCI--a PCI videocard would be a better bet probably. Although a 3dfx card would have the retro-cool quality to it

I don't think an AGP 8X card will even fit in a 2X slot, there is a notch difference to keep someone from doing that and frying something

 

[Koharski]

yeah, it seems they had some earlyish (pre GF6XXX) APG cards that were universal.

BEsided, I ONLY want this to run XGL on linux, because it's sleek and cool.

Also because I'm running a linux demoing station at a local computer faire.

Depends on the motherboard, the AGP 1.0 slots on older motherboards have only 2 notches, and agp 2.0/3.0 cards won't even physically fit into these slots as they have connectors with 3 notches.

Basically as long as your motherboard has an AGP 2.0 slot, any FX series card should work with it, but only run up to the maximum 4x speed.

If you've got a 1.0 slot though, your choices will be limited to 3.3v cards with 2 notches.

There are some nVidia FX 5200 series that works in AGP 2x (1.0) slots

but they are very hard to find

i just got one from ASUS
http://www.asus.com/products4.aspx?l1=2&l2=7&l3=9&model=273&modelmenu=1

it indeed works, and is cheap

make sure is that Exact MODEL, the other models of the same series are not AGP 2x compatible

Okay, what about this? My old Pentium 3 ASUS TUSL-2 motherboard has a 2X/4X AGP slot. Right now I have an ATI 9200 in it that works fine. My question is, can an 8X card fit this 2x/4x slot in that it is backwards compatible?

In other words, I understand that 8X will have issues with a 2X slot. But what about in my caes where it is a hybrid 2X/4X?

 

[AllGamer]

ATI 9200 is 2x compatible, all ATI 9500 and below are compatible, 9600 and above is a maybe, anything 9800 above is FOR SURE not compatible with 2x

My Voodoo 3 was 2x designed. It's a pretty sweet card too. If it wasn't 7 years old, I'd go and brag on all the tech sites about it.

 

[RallyMaster]

I think you might have to end up going with a PCI solution (PCI, not PCI-e).

 

[Koharski]

so what I'm understanding is that it's not the AGP 2x, its the fact that it's AGP 1.0 and I have to find a card with a front notch that will run at 3.3V? Is it safe to assume that if it has a front notch it will work?

 

[AllGamer]

nope.

it's the voltage thing, as i mentioned earlier.

so make sure the card can run on 3.3v

It depends really.. I think most if not all the posts in this thread are incorrect. While if you have an AGP 4X/8X card, you can't stick it into an AGP 2X slot because they're keyed differently. BUT there are AGP 4X/8X cards that support AGP 2X believe it or not. I know because I have a 9800PRO 128 and it supports AGP 2X, installed perfectly and benched fine.

Here is a perfect example of a strictly AGP 2X card AGP 2X

Here is a perfect example of a card that works on AGP 2X and 4X, AGP 4X is backwards compatible with AGP 8X.
AGP 2X,4X compatible (8X as well)

And finally, here is a perfect example of a card that works strictly on AGP 4X and 8X.
AGP 4X/8X

So long as you get a card that can work with AGP 2X/4X, you should be good. I believe FX5200s should support AGP 2X as well as 4X/8X. A Radeon 9800pro for a Celeron 1.4 is overkill, I know because I ran benchmarks and it was clearly bottle necked by the processor. So it depends how much you want to spend on a video card, so you may want to get a Radeon 9500pro, that way you can enable things like AA/AF with out penalty. A 9800pro would allow you to scale to higher resolutions+Eye Candy ETC, only problem is will your CPU be able to keep up..

I installed a 9700Pro onto a P3B-F board and it worked great.

I once installed a 8X in a 4X slot. Needless to say but it ran at 4X. I ran a 4X in a 2X, so an 8X could run in a 2X slot, but what a duh!
