Intel Pentium D 940 Prescott 3.2 gHZ oc 3.36
Asus P5N-T Deluxe 780i
Crucial Ballistix 2x2GB (4GB) DDR2/800
nVidia 9800 GTX 500 mb
WD sATA 1TB 32mb cache
iHAS 422 sATA 22xDVD w/lightscribe
Windows Vista 64 home

In my BIOS and Post, it shows my true GPU as the nVidia 9800 GTX, but in windows device manager it shows it as a 9800 GX2. I also checked Bellarc Advisor, Sandra Lite and nVidia website scanner has it listed as a 9800 GX2. I'm guessing the scanners are not really scanning the hardware but really scanning the programs.

For now, it seems like it is not a big problem because the driver updates for the 9 series are the same. But, I'm wondering, since it is reading like a GX2, is it performing as a GX2 or truely the 9800 GTX? Has anyone else had this problem? Is it Vista or did I doing something wrong building my computer?

Any imput will help and be appreciated.

You sure you don't actually have a GX2?

I have a evga 780i and it works fine for me...does the Asus version sux that much?

and lol it would be funny if you actually have a GX2 :D 
Someone accidentally put a GX2 card in the 9800 GTX box, or the GX2 chip in the 9800GTX GPU

well a gx2 is two chips so either your lucky or your board screwed up. Try putting it in an intel or amd chipset board, see if it still says gx2.

I doubt it is anything other than a Vista 64 bit error. It shows 9800 GTX in Post and it is Vista that changes it. I have a work order into Microsoft. I don't expect much from them other than trying to charge me the service charge and blaming my hardware, but we''ll see.

Maybe POST reads it as 2x 9800GTX? Maybe you did really get lucky...

9800GTX is the single best GPU in the nVidia 9 series. Not including the 9800GTX + which is the same GPU just factory overclocked. That's why it is $100 more expensive than the GX2. The GX2 is only better when coupled with another GX2. I have both Microsoft and nVidia tech support working on this issue, however I do believe it is the Vista 64 or the BIOS. I do want to troubleshoot it to the max before I do any BIOS flashing. That'll be my last resort. Although I have 4 computers, I don't have another board or computer capable of the needed 500W with PCI-E. I could try it in a friends computer but he probably won't want to give it back.

But really, you're sure that you don't actually have a GX2?

Go into DxDiag.

Also, how many PCI slots does your card take up, and how many power connectors did it need?

Also dude, if this isn't causing any problems, then why are you making a fuss over it?
April 13, 2009 3:53:19 AM

Yes, I am sure it is a 9800 GTX as it states in my BIOS/POST. It takes up just one of my three PCI-E slots. It uses 2 power connectors. I'm not making a fuss. I just want my computer to perform like I paid for it to, so I simply asked a question hoping someone has had the same problem and corrected it. If Vista lists it as a GX2, maybe it is performing as such, which is less than a GTX should perform. But I have never had a decent card like this, so I have no clue how it should perform. They are the same drivers for all of the 9 series cards. I sent a GPU-Z reading to nVidia with serial numbers etc. and they say it is a 9800 GTX. If in the end, they say it is performing as such, I'll disregard what it says on the device manager and go with it. I will do the DxDiag. though. Thanks

I'm pretty sure the 9800 GX2 is significantly faster than the 9800GTX. The 9800GX2 performs very similarly to the GTX 280, which is much faster than the 9800GTX+.

A gx2 is a lot faster than a gtx, but he has a gtx.

Exactly. If he has a GTX, and even though it performs like a GTX Windows is saying it's a GX2, either it's performing like a GTX (In which case you ARE getting what you paid for) or it's performing like a GX2 (Obviously it's not)

So either way, no problem here. :)

I'm not going to get into a pissing contest on what GPU is the fastest. It is irrellivent to my original question and is not helpful to a solution.

Ok lets say you have a car that looks like a ferrari on the outside but has a ford engine. Is it performing like a ferrari or a ford?

Is that really so hard to figure out by yourself? Jeez.

What I'm trying to say is your question is irrelevant. If it performs like a GX2, you've gotten a better deal than you expected, if it performs like a 9800GTX you have exactly what you expected. Pretty much, it doesn't matter which card it is because you payed for the weaker of the two, so either be happy it might be a GX2. There is no actual problem, just a few things likely reporting wrong.
April 14, 2009 6:09:09 AM

If it performs like a GX2, then I should have gotten 2 GX2's since that would equal the price I paid for the GTX. I understand what you're saying. My BIOS is reading correctly but when it goes into windows screen it states another. Maybe because all of the 9 series are using the same drivers. No problem at this point, but, in the future when maybe one specific update for my card only comes available. I can't update because my computer is reading another card. Nor can I benchmark it accurately.

And, the GX2 is not as powerful as the GTX. It has a larger memory but was designed to run in Duel SLI mode and thus the $100 cheaper card. As per the nVidia site, the 9800 GTX is the single most powerful GPU in the 9 series. All irrellevant anyway.

The 9800 gtx is the most powerful single 9 series gpu, but the 9800gx2 is TWO 8800gts on a single board, and one 8800gts = one 9800gtx.

It's quite a bit more powerful and more expensive than a 9800gtx, unless you paid far too much for the gtx. Anything more than $125 or so is too much for a 9800gtx these days.
April 14, 2009 9:33:24 PM

I feel bad for you if you paid $100 more for a 9800GTX than a 9800GX2.

I don't think you're understanding, though. The 9800GX2 has TWO gpu's on it, it always runs in SLI mode. You don't need to buy two, it's always more powerful than the 9800GTX (assuming SLI is supported in-game).

But it's irrelevant, it's fine. You don't need to worry, the whole "problem" isn't a problem.

^ A GX2 is two OCed 8800GT's, or an underclocked 8800GTS. Two 9800GTXs performs better than a GX2 by a good margin.
April 14, 2009 11:17:35 PM

I never claimed to be a genious, and my question was never what card is more powerful or faster. I have a 9800 GTX. That was never in question, and it is also verified by nVidia tech support. Whether a GX2 or GTX is more powerful has nothing to do with the question, or solution. Even if my GPU is running faster than it should, there is no way to really benchmark it. GTX has a max power of 140 W and the GX2 is 197 W. GTX 675 mHZ and GX2 600 mHZ. So, if it is running dependant on Vista, it will be running at 57 watts above max of my card specifications, and 75 mHZ below. That is a problem in my book, and if you had this problem, I'm guessing you would also be trying to solve it and not just write it off as if nothing was wrong. I thought this was a tech forum, so maybe I did make a mistake.

Could it be something like the wrong BIOS on the card? Just seems weird that GPU-Z could be tricked like that. I can't remember exactly back when I had SLI (which a GX2 is) but isn't there an option to enable/disable SLI? Do you have that on yours? Very, very weird.
April 15, 2009 4:18:03 AM

I do believe it is possible that the BIOS is wrong. I've heard mixed reviews about this ASUS board. I'm going to flash the new 1402 BIOS soon. What is confusing is that in the BIOS and POST it is reading correctly. Just in windows it changes to the GX2. I'm ready to try anything, even though I think it is maybe Vista 64 bit.

I've used GPU-Z, Belarc Advisor, sandra and a number of other software and they say the same thing. Problem is, they are not actually scanning the hardware but scanning what is in the device manager.

I'll flash the BIOS in a couple days, as soon as I get the time to get all of the downloads together on my flash drive.

I did send my GPU-Z readings to nVidia tech support and by the serial number they verified it to be truely a 9800 GTX. They also mentioned the BIOS, but I wanted to leave that as a last resort because I can't afford another mb if I fry it

Thanks a bunch for the imput and I will try it.

Just out of curiosity, what brand/model of 9800GTX do you have?

Also, I was referring to the Video Card BIOS, not the Motherboard BIOS. Something may have been set wrong in there, making it think that it is a GX2. Does GPU-Z confirm that it is running at the lower frequency of a GX2? (What is it, 600 vs 700 or something). In other words, what frequency is reported in GPU-Z/NVidia Control Panel.

As to flashing the MB BIOS, that is usually a safe procedure if you are careful. Your board may also have a nice feature like dual BIOS or a removable BIOS chip to make your life easier if something does go wrong. (Though, a Motherboard BIOS flash may not be necessary, but it probably wouldn't hurt).

And finally, did NVidia say anything else? I find it hard to believe that they are completely free from blame in this case, since Vista 64 doesn't just go around changing graphics card names. Many people around here use it (myself included) with no issues like these.
April 15, 2009 11:37:49 PM

It is an Actual nVidia mfg.
Bios Version 62.92.00.01
GPU-Z states that it is running at 600 MHz, which is what a GX2 Runs and should be running at 675 MHz.
I do agree with you. I'm thinking nVidia put in the single GX2 chip instead of the GTX chip is a possibility. My computer is running fine and my graphics are great. But then again, I have no idea how it should run since my last GPU was a Geforce 5200. Quite a bit of change in there. I have no problem with the performance. My worries are, if it is running at the 197Watts that a GX2 runs, will it burn up my card since the GTX is rated at 140 max Watts? I'm hoping there is actually nothing wrong other than the wrong name in the device manager. I have no idea how to correct the GPU bios other than sending it to nVidia. As for the mb bios, I will flash it soon as I figure out how to make a ms-dos boot disk in vista 64. I am confident that I can flash the bios with no problems. I just want to be safe, since I am compulsive...if it can be screwed up, I can figure out a way to screw it up...lol.

It is possible that my old mb BIOS is before the GTX was introduced and just doesn't recognize it yet, so when I flash it with the new 1402 it should be fine. What confuses me is that it is reading correctly in the BIOS/POST screen as a GTX, just when it gets to windows it changes.

I appreciate the imput and I will look into everything you mentioned and more, including sending it back to nVidia if need be.

What I plan to do later is uninstall the GPU (hardware) from the machine and use the onboard graphics while I delete the device drivers. Then I will try to download the drivers manually and not let Vista automatically detect and see how it works.

masterplots, I apologise for being so short with you before. Just blame it on womens stuff :D 

could you download 3dmark06 and post your score? With that we'd be able to get a decent idea of whether or not your card is underperforming by a lot.

Also, feel free to pull the gpu out and reinstall windows. A fresh install of windows can work wonders.
April 16, 2009 2:02:13 AM

No apologies necessary, jennyh. I probably deserved it anyway to get my head out of my butt. I was thinking of a GT and saying GX2 when saying the GTX was faster anyway. I did do my homework before I purchased and knew the specs, just got the name caught up in brain lock. The Ferrari thing was good though...lol. Problem is, those cars aren't depending on Vista telling them what to do.

Originally, I thought it was because the same drivers were used for all of the 9 series until I started doing Benchmarks.

I will try out 3d benchmark. Now I do believe it is underperforming even though it is a tremendous improvement over my last GPU. I can get it to perform at the rated 675MHz if I overclock, but I'd rather hit that naturally.

Thanks for the idea and I'll surely do that. Soon as my WoW patches are finished downloading.:-)

Just to clear one thing up - don't worry about the power consumption. Here's why, the GX2 is just two 9800GTX chips underclocked. So, if they put two in, you got a free upgrade (unfortunately not the case, it appears). If they put one in and coded it like a GX2, you just ended up with an underclocked 9800GTX. Obviously, this isn't acceptable as that isn't what you paid for.

Updating the MB Bios can't hurt (assuming it works). Seriously though, I've done it tons of times without any problems.

I second the reinstall Windows choice (if this wasn't already a new install) as a last resort. I know it is a pain, but it seems that the weirder the issue, the more likely it is to be fixed by a reinstall.

I also didn't realize the GPU was listed in post. I guess I need to pay more attention (I know the CPU is).
October 7, 2009 6:35:06 PM

I am also having this exact same problem, except I cant update my graphics card with any of the new drivers, and when I try it wont let me run any resolutions beyond 800x600. So for me this is a huge problem. I also feel like my card is not running as good as it should be.

Can you clarify your problem. It doesn't sound like you have the same issue at all.
October 7, 2009 9:34:53 PM

I have a 9800gtx card, At boot up my bios states the same, but in windows and in device manager it sais it is a gx2. I looked at its frequencies and its running at 600mhz. What a gx2 runs at. I tried overclocking it too 675mhz what a 9800gtx should be running at, and ran into a load of problems. So I did system restore and everything is running good again.

I also put the graphics card in a different Mb and had the same exact problem. This was on a windows xp and my main computer is vista. The only drivers that work with the graphics card on both computers are the ones the came with the disc. If I try too install any updated drivers off the nvidia website the graphics card wont support any resolutions above 800x600. So the drivers are not working with the card at all.
