swap GPU: 7700go --> 8600GT

ok. i heard a billion times...that you can't swap the GPU in laptops. i know that.

but why not? I have a G1 and I really wish to just swap the gpu for the 8600GT (JUST the gpu, NOT the santa rosa, hdmi, esata, and 200mhz faster cpu..all that crap)

so...it's pretty much the same chassis. same design. same # fans. same model for crying out loud. and it's still PCIe. so why wouldnt getting a 8600GT part and replacing it w/ the 7700go card work?

 

The graphics cards are usually integrated directly onto the motherboard.

Laptops do not usually have a PCIe slot...and even if they do choices are VERY slim for them.

 

You'll have to replace the motherboard since the 7700 was never mentioned to be modular. However, if you change the motherboard, you'll need to change the chassis, and everything else.

Easier to just buy the G1s.

 

Its built into the motherboard... It would be like trying to upgrade your northbridge on a desktop computer. Unless you want to try to solder the new GPU, ram, etc.... onto the old board, and hope to god they both have the same layout(which they will not.) good luck, but otherwise, you are going to need to replace the whole thing.

 

Unfortunately there are many reasons why it won't work (the main points already highlighted above). Why not just enjoy the go 7700 until the rest of the system shows its age and buy what's new then? The go 7700 is still a very respectable GPU in terms of gaming and will be for some time.

 

Asus G1-AK024C with 7700. This is dedicated card and does have MXM thermal registry added for it. You can open the back you will most likely see the card under a heatsink. It is a MXM type module.
Now the problem will be finding which one it is and then finding a 8600GT using the same type then you are good for upgrade.

For more info on MXM http://www.mxm-upgrade.com

 

take a picture of your gpu, then ask a g1s owner to take a picture of theirs.

It is a removable gpu, unlike what a few people have said.

If they are the same they COULD be compatible. Next find a source for the part.

Because the g1s has a new motherboard its possible the gpus are not compatible.

I dont know if anyone has posted a picture of the g1 gpu here or not. But you can. See if its just standard mxm. Or if reverse mxm like on the a8js.


take off the big peice on the underside it should be visible

 

If the G1s uses the same reverse MXM GPU as the A8Js, would it be possible to swap the 8600M GT into the A8Js?
Creating something like the A8Ultimate

 

that would be nice.

But its not necessary. I always assumed the g1p and the a8js had the same gpu exactly because of things i read on this board.

They have the same vendor number and ram in the gpu....

they might not though. Im hoping the a8js and the new a8j are compatible and i will try to upgrade to 8600 gt or gs even.

I dont think anyone owns the a8sc yet to even tell us.

 

They are the same GPU. I was talking about the G1 s with the 8600M GT. And don't 'upgrade' to the GS. It has lower performance than the Go7700, except it has DX10.

For some reason, I don't think the update to the A8Js will be A8J<any_char_here>. Its most likely to be A8Sv if it stays in the A8 line; otherwise F8S seems likely.

 

Another factor is voltage requirement; maybe the 8600gt draws more power than the 7700go requiring additional motherboard/power capabilities.

I would very much like to move up to the 8600gt though if it were possible!

 

Ok but what I mean is they had the exact same circuit board and formfactor

that the gpu was the same part.

A while ago you could order the a8jm gpu in the asus estore. Asus would stock the gpu part for repairs.

If you can figure out whether it fits, I think the only way to figure out if it would work would be to try it. Get one somehow from a dealer or asus.


I definitely wanted to do this when I bought my computer. I got it when merom was new, well that cpu is going to be compatible with software for like 10 years its a really big step.

But dx 10 was going to be a big step too. I hoped it was possible to upgrade although I acknowledge its very remote.

Asus could easily use the same form factor to save money. The gpu in the a8js is on a mxm 2 board its just flipped around. Asus probably has 10 billion of them

 

I think Stamar meant no one has gotten a a8sc so he can't check if the card looks the same.

I think update will be called A8Sm or the weird A8Ss

 

Sure.... a8sm is most logical.

f8s also.

 

WEll

when we can get an owner of a g1s or an a8s whatever to take the large panel off on the bottom and take a picture well know.


I do think there is a picture of the g1p gpu somewhere in this forum but its been a long time since Ive thought about it and i dont remember what i thought.

Theres lots of pictures of the a8 series gpu. youve got to remember the g1 is also the a6 its actually older than the a8 although its the same year. all the same gpus are in it, I always assumed it used the same parts.

They are not compatible with the ones in the v or w series those are totally different. And the newest built ons use standard mxm

 

Doesn't A8Ss sound nazi-ish? The second update will probablt not (what A8Js was to the A8Jm) be called that, if the model is not dicontinued.

 

a8 is one year old.

It will have models into 3 years.

I mean its like w3c w3v w3j

I cant even remember the change but the first two are the pm chips with different buss speed , then the w3j napa chipset then eol.

 

So A8 will be Napa, Santa rosa, Montevina? Ok, then it's likelier an updated 15,4" card will show up (8650M GT? 8600M GTS?).

 

Noone mentioned heat constraints... Even if the format is exactly the same and the card is discrete, and the power supply is correct, the generated heat could be higher and the cooling system won't support the new card in that case.

 

We all were thinking it, but nobody wanted to say it out loud

 

For heat: Underclock and slather a lot of AS5 on it
For power: undervolt if necessary

The thing is though, I don't think it will have either of those problems, because there are 14" laptops coming with this card installed (A8Js update, Compal IFT00, Zepto 6224 I think), so the heat shouldn't be that much of a problem regardless; and I doubt that power will be an issue either. I could be wrong though, and all of this depends on the G1S using the same modular GPU interface. I think I will ask Ken (GentechPC) if he could check for us.

 

I already posted a request in the G1s vs F3Sv thread.

Another question is, does the G1p use the same card? While it most likely does, if it's different, like the placement of the GPU itself is a centimeter to the side, they won't cool properly.

 

No, as long as the interface is the same and the A8 heatsink attaches to the G1 GPU in the same way the G1 heatsink does, it should work fine. The placement of the GPU in the actual laptop shouldn't really matter.
And the nice thing with the A8Js heatsink is that its pretty heavy duty, seeing as it needs to deal with the Go7700 already. I think that a slight underclock plus some AS5 should make that work fine.

And I saw your request. You beat me to it, but I added one too

 

Has there been any development here, any new information on the table telling us if we can upgrade the gpu?

 

Not really, we're still waiting on pics. Ken at GenTech PC doesn't think we can actually do this successfully, but we should be able to I think, as long as the cards have the same interface.

 

Nope, sorry. What's really needed is that an A8 or F8 is actually released with a 8600M GT. Only then will se if it possible (most likely not).

 

You have no idea how a thermal interface material operates, do you?

 

none of that matters. what matters is that the bios is its own preventative measure that prevents you from upgrading any gpu. Aside from the bios no its not possible plain and simple.
