Vista Not recognising my second GPU??

Hey everyone!

I recently purchased a Alienware m9700i(i know its fairly old)and was planning to use it for mobile gaming. I purchased it from ebay so it is second hand. The laptop came and i booted it up. It had Windows Vista. I looked on it and it said all the specs and said that SLI was on which was awsome. However! I didnt want to stay with windows vista so for that reason i install windows 7 64bit and wanted to work from there. I installed all the drivers for Intel chipset, graphics drivers etc etc
Then, when i went into control panel i realised that there was no enable sli option anywhere!
So i decided to check device manager, and it seems that only 1 graphics card has been recognised. So i thought i should go back to windows vista, so i installed windows vista and went back to how it was before, and funnily enough now windows vista isnt recognising my second gpu. There is no recognition at all that SLI is even there.
Can any light be shined on the situation here? I really want to boost up my frames in crysis.

P.S: It seems that when i play crysis on High my gpu hits around 93 degrees and starts to lag. Is this because its meant to be in SLI or what? I thought that i might buy a cooling pad for that anyway.

Thanks for reading!

Well, not that I ever had a SLI-enabled gaming laptop, but on my desktop rig, SLI is enabled through nVidia control panel. You might want to try that.

You need to load the current Nvidia drivers to enable the feature. Go nvidia.com and you'll be good to go.

I have got all the latest drivers and updated with everything :/  And there is no sli option in the nvidia control panel(it doesnt even seem to realise there is a second gpu there at all?

Are you sure the second GPU is installed AND enabled in the BIOS? Are any unknown or problem devices indicated in your Device Manager? Does Device Manager see both GPUs?
May 9, 2011 4:16:13 PM

Doesnt look like there are any errors in the device manager, just 1 gpu. However what do you mean by checking in the bios?
May 9, 2011 4:30:51 PM

It says that drivers for 64bit OS, but ill have a look and see if i can find a 32bit version :D

OK. Your original post indicated that you were using 64-bit Windows. Also, go into your BIOS and see if you can determine whether or not 2 GPUs are actually installed (or not).

Oh yeh i forgot to say that i went back to vista 32 bit :/  Btw when you say bios do you mean when i boot up. Because i checked in there and it says nothing about my gpus?

Understood on both. Yes, when you first boot up (usually press the F2 or DEL key to access). Somewhere there should be an area that tells you the basic system configuration or an area that has peripheral details.

Still, are you 100% sure the system has 2 GPUs? If not, SLI can't be enabled. Also, if your GPU is hitting 93C, that is getting pretty hot (water boils at 100C). Since this is a used system, the fans may be dirty and not cooling efficiently. Try a blast of compressed air into the intake and exhaust ports to clean the pipes (so to speak).

Thanks for all the Help man :)  But yeh im positivily sure that my config had 2 gpus when i got it. It definatly said SLI enabled. But now installing over it has lost the ability of enabling it again. I would be suprised if one of my cards died while installing windows 7 and windows vista because ive only had it for a couple of days now. And with the overheating thing, yeh i need to clean out the inside :)

Ahhh damn the Nvida driver didnt work! And the alienware one you sent was for the GO 7900. :(

The specs for the M9700 list either a 256MB or 512MB 7900 GS mobile GPU. What does yours have?
May 9, 2011 5:23:51 PM

Mines a M9700i which is a 8700m gt.

I just saw in your OP the little "i" after M9700. To clarify, you have an Intel processing and not the AMD version, right? If so, that is an M9750, I believe. Like this one, right?

If so, the same drivers should apply (as provided by Nvidia). The Alienware link is:

Yep, i have an intel core 2 duo. Im downloading the first one that is on the list right now. Lets pray :p

Ahhhh, still not worked! Damn, my hopes are getting low here now :( ( I dont know whats up with it, because the other day it was all fine but as soon as i installed windows 7 bam 1 of my gpus dissapeared! Now back to vista and still no luck :/ / What else can i try??

Going back to Vista and installing the SLI enabled drivers should have done the trick if both GPUs are operational. I think you need to dig through the BIOS to verify the second GPUs presence. Also, another way to check would be to load a Live Version of Ubuntu (or any modern Linux distro) to see what it detects.
May 9, 2011 7:24:10 PM

Ok, i just opened the laptop up and had a quick look in. From the picture you showed me it doesnt look like i even have an sli cable??
But what confuses me here is that when i first got it it said in the welcome manager
8700m gt SLI?
So now im really confused? But from the looks of it, that black cable in the picture isnt there(which looks like the SLI cable).
Any ideas?

Are there actually 2 GPUs and no SLI cable? If so, you may just need to order one.

But then why did his first Vista installation recognized SLI?

If you got it second-hand, why don't you just contact the person you got it from and ask whether there was SLI or not?

Thats exactly what i said, i was really confused why it was working in the first place... And great idea about contacting the person didnt think of that :p

Thanks man!! But it said $ and i live in the UK so do you think they accept paypal?

It is possible, the site does list PayPal for a payment option. I would contact them if I were you to see what you options may be.

Also, all I did to find that link was I googled on the term "M9750 SLI cable".
May 10, 2011 5:18:51 PM

Ok, things are getting really complicated and frustrating now! Seems like my second video card doesnt even have an SLI slot????? I can see one on my primary video card but i cant seem to find one on the secondary. Ill upload some pictures in a sec.
May 10, 2011 5:33:31 PM



Theres the whole of the back of the laptop
a c 218 U Graphics card
May 10, 2011 8:03:23 PM

There is only one GPU in that system. The second slot has a heatsink, but no GPU. That is the problem, my friend. Sorry to be the bearer of bad news. SLI capable, but not enabled due to a lack of a second GPU.
May 12, 2011 5:40:17 PM

Lolol haha sorry im still a noob to laptops. Thanks for the reply and thanks for all the help man! How can you tell there isnt a gpu there? :p 
May 12, 2011 5:42:09 PM

And also do you know where i could by that second gpu?

There should be a card under the second heatsink that looks just like the first one.....

Best bets are eBay and Craigslist. Google Shopping may also be an option, like this link:

http://www.google.com/search?q=m9750+video+card&tbs=sho...

There are several on-line sources of used computer parts. Since you are in the UK, your options will be different, but I am sure you can find a sources with a little research.

Make sure you get the same type as the one you have now, or 2 matching compatible GPUs. You can't mix GPU models.

Good luck, my friend! HOOAH!!!
May 12, 2011 8:10:58 PM

HOOAH!!!
And also would i buy the exact same gpu as the primary gpu or would i have to buy an sli version or something because the second gpu doesnt look the same shape as the primary.

Yes, you get the exact same GPU. Have fun!
