URGENT: Is it possible to upgrade a 6770m to 6990m?

I just literally bought a dv7t Quad Edition from HP a month ago and now i hear the 6990m came out. I can play most games on fairly high settings, but with BF3, MW3, and other games coming out, i was wondering if it was possible to replace a 6770m with a 6990m or if it's even possible to change those kinds of graphics cards out. Thank you in advance.

 

No. The GPU is soldered on to the mobo. If you want to have an upgradable GPU, you have to get a laptops that supports MXM, but most of them don't support switchable graphics so they have worse battery life.

 

And even if you did have MXM, you still couldn't use the 6990M because it draws a lot of power so the power supply couldn't handle it and it generates a lot of heat (3-4 times more than the 6770M) so the machine would overheat. If you want to use something like the 6990M, you have to buy a laptop with the proper cooling and power requirements. As you would expect, these tend to be thicker and heavier than dv7t.

 

First off, you have to determine if your notebook has an MXM slot, followed with ascertaining whether the slot in question is the same like the one 6990M uses.
Third, buy the 6990M and test it out.

Since the dv7t Quad Edition is a 17.3" laptop, size and overheating isn't the issue (heck you can get it in a 15" one as well).

It's a tricky one... I was under the impression that HP soldered their gpu's on the motherboard (or was it a different manufacturer)?
As i said, you must determine if you have an MXM slot (which is compatible) and then check the 6990M specs and try buying it or borrowing it to see whether or not it would work.

 

The dv7t is definitely not MXM.

 

As many people have said, no it is not possible.

But it shouldn't be an issue. Did your laptop somehow get slower or less-awesome, just because you found out that another GPU is out?

 

not to mention that IF the dv7t used a mxm slot it would be 2.1 not 3 type b, so no dice changing to whatever higher end gpu

 

That's how it goes. It's how Apple thrives

 

How are the dv7t and apple related?

 

But the 6770M is considered a 'Tier 1' gpu.
At least as far as Notebookcheck goes.
So it has to be determined if the laptop has the MXM slot and one that would accept the 6990M.
I'm not sure on which MXM slot the 6770M goes though.

 

as I said its a mxm 2.1 slot for the 6770m

and a mxm 3 type b slot for the 6990m

there is also the problem that the heatsink for the 6770m wouldnt handle a close to 100W tdp card and it would need to be modded heavily, aside that we enter the size problem, since the mxm3 is quite larger than the 2.1

 

I don't really get how come you want a 6990m but didn't want a 6970m. Like The power difference between the 6970 and 6770 is quite large. The 6990m is not available in non enthusiast class systems. You would need Alienware/Sager to get it. There is no way its going in a 6770m "good mainstream laptop". The heat generation, power draw everything is built so that it can only work in a enthusiast class system.

If you really want to be upgrading GPUs and stuff get a desktop. Its much more economical and is about as hard as putting Legos together and installing some drivers.

 

The graphics card is not MXM. It also isn't not MXM in general, but on this laptop its not mxm.

Point being, graphics cards models do NOT indicate the MXM type. The manufacturer decides how interface with the core long after the model name and specifications are released.

A 6990m could be on mPCI-E, normal PCI-E, mini PCI, mxm 2.1 or soldered to the motherboard if the manufacturer desired. It just so happens that the only 6990m in existence are Dell and Clevo mxm 3.0.

The 6770m was released soldered to many HP and other motherboards, and also in MXM 3.0 form.

No, the 6770m has never been made for MXM 2.1, neither has ANY 5000 or 6000 series card.

Here mr MM, you were correct:

No, that is absolutely not the right logic. Just because its 17" doesn't mean it has more copper or a bigger fan than a netbook honestly.
Some laptops use the same motherboard and cooling system in 15 and 17" chassis.

Not to mention many laptops that DO support different MXM cards have totally different heatsinks for different cards.

Its really not too tricky. For the dv7t, not happening. You can see a GPU soldered on here:

FYI for the Elitebook 8740w, 8760w it should work just fine.

 

what mxm is the 6770m?
