Thanks every one who did reply to help me out. Big thanks to StamatisX for the link to creat bootable usb. Now I successfully install Gtx 560m into my M15x!

Being on A09 now. Thanks everyone. Attempting to get it work with gtx 560m.

By the way, any guide for gtx 560m with M15x? or just need to plug it in?

Thanks everyone. I am confused about the version, too. The problem is with the card work on M17x, when I ask Dell, they said it will be a little bit bigger than the one in m15x of Dell. Anyway, I already ordered one gtx 460m from Dell. May I return it and go with 560m? What do you guys think? Thanks again!

Hello guys, just have one question about GTX 460m. I saw a gtx 460m on eBay. I ask the seller that whether will it work on my M15xR2 or not. I bought my M15x since 11 months ago from Dell with 1 year basic warranty and it is still under warranty until December 20, so I think it is M15xR2, is it my bad or am I right? He said that the card works fine in M17R3 and he think it will work OK on my m15xr2. What do you think about this, just let me know any advice of you because that seller doesn't accept the return. Thanks!

Sorry, almost forgot to answer... the first link is a 470m, and for a quite decent price imo. The second link isn't a 470m, at least not the card which is shown in the picture...

The 470m works fine if you follow my guide and flash the modified VBIOS, but it might have some issues with overclocking. But it runs pretty cool, performance is decent.

6970m performs better, but also runs warmer. You might need to slightly modify the heatpipe to get the heatsink fit as tight as possible.

I'd love to exchange the card for you, but I'm afraid it won't be worth the way around half the world for $100

Whether 470m or 6970m, it's really not that hard as long as you work carefully and follow all the steps in the guide I attached to the first post. You could also ask a local computer store to do the work for you, but I doubt they will do a better job than you can.

Is there anyone local who can help me to install the 6970 at home please? Willing to pay, I am living in Worcester, MA. Please please please!

Can you check these links for me please nvidia 470m gtx 3.0 TYPE B 1.5GB GDDR5 Video card | eBay and Nvidia gtx 470m MXM 3.0 B | eBay . They are both GTX 470m but different color. Why? Which one is compatible with alienware m15x? Thanks !

Hey, yeah, the 470m will work with the M15x, but you'll need to use the modded VBIOS which you can find in the first post of this thread.

Anyway, the AMD 6970m or 6990m will work even better in the M15x and is cheaper and more powerful, you might want to consider those cards as well.

About the 460m... make sure you're on the latest BIOS version (A09), the 460m requires at least BIOS revision A07 to function properly in the M15x. Also check the fan cables, the system won't POST when they're unplugged.

Yes sir my BIOS version is A08 and fan cables is plugged in but I don't why it shut down. I know the 6970 is better but your guide seems hard for me. I can change the graphic card but I don't understand about the x-plate and I am not good at changing temps or bla bla bla. So I am afraid . The GTX 470m seem much easier to do but look like there are no big difference between 470m and 460m. By the way, can you check this link please nvidia 470m gtx 3.0 TYPE B 1.5GB GDDR5 Video card | eBay . Is it ok to buy? I like the 6970 and 470m so bad but I am chicken at managing stuff of graphic card. I am willing to pay $100 or more for guy who helps me to do it at home

I have a question that I am using Alienware m15x core i7 740qm and just 4 GB DDR3 of Ram. Can my laptop upgrade to gtx 470m? By the way, I did purchase a gtx 460m from eBay, when I put the card in and turn on my laptop(the card completely fit my laptop and be seated correctly), it just shut down in 2-3 seconds, any one knows why? When I put back my gt 240m, it works normally. Thanks a lot for any comment and advice. I am chicken

I already try to update the BIOS but I really have problem with bios update. I don't know how to create a bootable disk. Any help? Thanks.

I forgot, my laptop is Alienware m15x CPU core i7 740QM, gt 240m and 4GB DDR3 of RAM

I got a GTX 460m MXM 3.0 type B on eBay. I successfully install the card into my laptop. It completely fit my laptop. I put everything back and turn on the laptop, it shut down in 3 seconds, I can't even see the screen with alienhead. When I put the GT 240m back, it works normally. I am thinking about the old driver, so I delete the old driver for gt 240m and then install the card again, still the same issue? Any one has suggestion for me? This is the link eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices that I got the card from eBay. Really need help! Thanks!
