AGP8 work in AGP2 SLOT

GATEWAY
September 2, 2007 at 10:04:47
Specs: XP PRO, PIII/256

I have been given a PIII/700MHz Gateway that I'm going to set up for my 6yr old. It has a 15" flat panel mon with DVI and its got a problem. I can borrow a 8X agp card with DVI from a friend to make sure it's the card, will it work in the 2X slot?

Possibly. Different voltages are involved and using the wrong one could fry the motherboards/card.

See here and compare the AGP slot with the card. Modern cards are usually backwards compatible with older AGP slots but the reverse is not true and there are exceptions. Even if the card fits, it may still not work becasue of the voltages.

To be on the safe side I would look around for an old 2X AGP card. They can usually be picked up for peanuts but getting one with DVI might be a problem.

I wouldn't take the chance. Generally, an AGP card is only backwards compatible one generation...that means 8X should work on 4X, but not 2X. 8X AGP runs at either 0.80v or 1.50v. AGP 2X is usually 3.3v which means it will fry an 8X card.

Are you getting the initial POST beep. If not, it's probably not the video card or monitor at all.

Check if the card fits in the slot or not. If it fits in the AGP 2X slot, it will work. Some AGP 8X cards do fit and work in 2X slots. The Radeon 9800Pro and GeForce 5700 Ultra are two 8X cards that I've used in 2X slots.

If it doesn't fit, it's designed only for 4x/8x slots and will obviously not work.

Thanks for the replys. The system boots and runs just fine, the video is garbage. I've put an old ATI agp card in with a regular CRT and have no problems, really want to use the flat panel because of very limited desk space. Just trying to figure out if it's the monitor or the card.

If you used a simple adapter, such as one to convert a DVI port on the monitor end to connect to a a 15 pin VGA cable, that won't work unless the card is designed to be able to use such an adapter and has the circuits built in to do that. And the wiring within those simple adapters may vary, so a generic one or one that works with one brand's video card that has built in VGA/DVI capability won't necssarily work on another brand's card. Commonly the adapter is used on a DVI port on the card to convert it to VGA use, not the other way around, and not on the monitor end of the cable.
The card works fine with a regular CRT so there's probably nothing wrong with it or it's drivers.

However, if the video does have VGA/DVI capability, and you have a DVI port on it to connect the DVI monitor to, if you have settings in Windows set to something the CRT can display but the DVI monitor can't, the display will be garbage, or you will get no display, on the DVI monitor.

As far using a 8X card in the 2X AGP slot goes (actually it's 1X/2X) it would help a lot if you told us which card you were thinking of trying.
In general most recent 8X cards cannot be used in 2X slots, but there are some models with older chipsets on them that are 2X/4X/8X or 2X/4X capable that are still available new if not from major manufacturers from clone manufacturers, or that are available used.
The fastest AGP speed is usually emphasized in ads or specs for a card. The card and chipset may be capable of 2X, but you might have to dig around on the manufacturer's web site to find that, or if it is a clone maker's web site the info may not be there but you can find that info on the maker of the chipset's web site.

I have came up with a DVI to VGA adapter and have confirmed that it is the card. It is a 16Mb TNT2, which has to be one of the first cards with DVI, the system was built in 2000.
The only thing I have found so far is this;
http://www.newegg.com/Product/Produ...
According to the one review I cannot use it for primary video but I see nothing from the specs or website to confirm this. If that's right I'm looking for suggestions
Thanks EVERYONE for your help. Chuck

Does the TNT2 have a DVI port? If it does, check your Display settings in Windows - you may have some setting set to something a CRT monitor can do that the DVI monitor can't do.
If it doesn't have a DVI portn there is no such thing as a card with a single VGA port that can be adapted to a DVI port - it's always the other way around.

I wouldn't go by what one guy says regarding whether a DVI monitor can only be secondary. There's a small possibility that's true, but some people don't know they can switch which monitor is primary or secondary in Display - Settings in Windows. If you really want to find out for sure, look up similar ATI brand name cards on the ATI web site that have the same chipset - ATI specs manuals are often more thourough.

You're not limited to just relatively old ATI chipsets for cards that can use 2X slots - I know for a fact the 9200 and 9550 cards also support 2X, but when you look at info on many clone card websites that isn't clear. Most if not all 9600 cards are 4X/8X only; I believe all 9800 and higher cards can only support 4X/8X or 8X only.

Apollo also has other cards with newer ATI chipsets that definately support 2X. You get the benefits of the newer chipsets, but at 2X speed.
http://www.apollovga.com/products_v...

e.g. 9250 64mb (but VGA port only)
http://www.apollovga.com/ATI%20Rade...

9550 64mb (but VGA port only)
http://www.apollovga.com/ATI%20Rade...

This 9200SE probably supports it too, but that isn't specified - you could find out whether it does by looking up cards that have that chipset on the ATI site.
Both DVI and VGA ports:
http://www.apollovga.com/apollo9200...

Some lone card mawers ave better info than others. Sapphire has terrible info. PowerColor might be better.
E.g. here's an ECS card that you might still be able to find as old stock:

http://www.ecs.com.tw/ECSWebSite/Pr...

(ECS models with a DVI port have a D at the end).

I now nothing about NVidia chipset cards.

The card has only the one DVI output and it is the card that came with the system. I checked all settings, ect, video is garbage. Was the same after I installed XP. I'm not wanting to spend alot for the card, might even see if there'something on Ebay.

"I've put an old ATI agp card in with a regular CRT and have no problems.."

"It is a 16Mb TNT2, which has to be one of the first cards with DVI, the system was built in 2000."

So I can conclude the TNT card doesn't work with a DVI to VGA adapter and a CRT either? If so, you could try cleaning the contacts on the card with isopropyl (rubbing) or methyl alcohol (a major component of gas line antifreeze), and possibly rubbing it's contacts with a non-abrasive pencil eraser (pink, or a white or tan art eraser), and making sure it is well seated in it's slot, but it's probably toast.

I got an ECS 9200 "REX" about 6 months ago locally for $55.
I'm not sure which model that is. VIVO (Video in, Video out) instead of TV out. DVI and VGA ports. It has a plastic shield over the video fan with a T Rex graphic on it.

Check smaller local places that build computers that have a lot of computer pieces - many of them have web sites. Some may have 7000 series or 9200 series cards or the 9550. When you factor in shipping you usually have to pay in addition when you buy online, local places like that may be cheaper - they are for me where I am in most cases.

I have found a 9100 but cannot come up with anything to let me know if it will work. I haven't been able to find any info on the ATI website. Has this card got the same chipset as the 9200?

You didn't look very hard.
All you have to do is search for 9100 on the ATI part of the AMD/ATI web site and you get lots of "hits".
The 9100 chipset has "1X/2X/4X/8X interface"

"Has this card got the same chipset as the 9200?"
No.
The Radeon 9000 and 9100 chipsets are mobile chipsets that were used primarily in laptops and in video embedded in (built into) mboards.
The only clone video card card maker that used the 9000 and 9100 chipset listed on the ATI web site is Sapphire.

Drivers here:
http://www.sapphiretech.com/us/supp...
Only one card listed for 9100.
XP drivers - are no longer being updated - latest version is a 2006 one (unless you can read German).
Apparently there is no other information about the Sapphire card with the 9100 chipset on their web site.


or here:
http://ati.amd.com/support/driver.html
Professional (Win 2000), or Linux, or Windows ME\98 - Integrated/mboard.
Drivers are no longer being updated - latest version is a 2004 one - the Professional (Win 2000) drivers will probably work fine in XP.
I did some checking on the ATI site.
- 9250 drivers are available for XP, but are no longer being updated either - latest version is a 2006 one.
- 9550 drivers and up are still being updated - latest version this month.

"OK, but will it work?"

I can only say probably.
The chipset is 1X/2X/4X/8X capable, but it's up to the clone card maker whether they hook up the circuits for 2X to the contacts on the card edge. For a card of this age (they first came out in 2003) usually they do, even if the specs on the clone card's web site don't specificially say the card is 2X capable.

You may be able to identify which clone card maker made the card. Sometimes the manufacturer is printed on the card somewhere, or there is a manufacturer specific model number or model name printed on the card or on a label on the card. E.g. The Sapphire card name is Atlantis, the Gigabyte card name is Maya something (Gigabyte usually has good information).
See the first link in my last post.
Other such as ECS may have made a 9100 card too.
In any case, there is almost aways a part number on a label on the card that can be looked up on the ATI website and the first part of that can tell you which manufacturer made the card.
E.g. an ATI made Rage 128 card I have starts with 1025, the number is beside P/N on a white label; a Sapphire 9600XT card I have starts with 1024, the number is beside PN on a white label; a PowerColor 7000 card I have starts with 109 and it's stamped in black ink on the card itself.

Obviously there isn't enough info on the Sapphire site if it was made by them, but if was made by Gigabyte or PowerColor or another clone card maker, they may still have the info you are looking for on their web sites, but that may be in the Legacy/Discontinued card information.

If you can't find the info for the card, it will probably work for 2X.
If you don't want to take that chance, if you haven't bought the card yet, find another card that you can find the 2X capable info for.

I think this an actual ATI card. There is no other manufacturer name on it. The label says Radeon 9100 128M ddr v/d/vo. P/N 1024-F149-2D-SA. The fan has an ati label on it.
Only gave $10 for it so I guess I'll see if fits the slot and see what happens. This is the only thing I could find locally and if it doesn't work or go up in smoke I can return it.
