Another Acer5920g Upgrade MXM question

Hello

Recently I found new hobby - upgrading my acer 5920g.
Currently I’m running t9300 C2D, and ATI 4670hd.

There is also x9100 on its way from china.

Lately popped into my head new idea, probably stupid but still I am looking forward to discuss it further.
It is about installing new gpu. I know that 4670 is probably the best mxm II but there are still on the market cards mxm III with the same connector as I have in my 5920g.
for example:
ATI Mobility Radeon HD 4850M (M98) GDDR3 1Gb MXM 1.3 Type III
or
ATI 3870 Mobility Master Laptop Videocard Crossfire Alienware M17 R1 MXM 3870M | eBay

So my question is: If any of You have idea if some of this cards will work in acer ?
I know there is problem with physically fit the card into this model but I’m certain that I can manage to modify heatsink, radiator end fan to solve that issue. But i really has no idea if there is any chance that those card I mentioned above will work.

Anyone can provide some information, or expertise if my idea is possible to achieve ?


P.S. Sorry for my lack of language skills, but still - I hope somebody will be able to understand me

 

No way. OK, no easy way, definitely not very portable, and A LOT OF WORK. You have to think for a way to attach the CPU side of the heat-sink, since the two GPU side screws have to go. That's one, two, you have to dig deep into the fan's place. Three, you have to relocate the fan and radiator, and four you have to go big since those are 75W cards.

 

I am very aware of that difficulties, but anyway the most important aspect for me right now is that
- if our lappy will be capable to power up this kind of cards if I get proper power supply
- if those card has any chance to work - most of them are master or slave cards from alienwares, if that makes any sense to try run single master or slave card in acer 5920g if hypothetically
card fits after altering cooling system ?

If I get some confirmation here that it could be possible I’m planning to finish my work somewhere at the end of this year, but this whole altering thing need to be done for exact card because of coils placement.

 

It has direct line to the power supply which is good for around that much - 75W. So yeah, in theory it should work. You want to try the Master, or if you have BIOS programmer, get Slave and flash the Master BIOS. I'm not very sure but I think that many moons ago someone did tried, with 4850 sitting at angle and said that it was booting fine. I still think that it's a massive waste of money AND time, but it's up to you. I mean, it's hard to cool overclocked X9100 (E0 which runs quite cooler than C0 (same as X9000)) and HD4670, I can't even imagine what and where would be the cooling of the HD4850 alone. Good luck!

 

Thank You very much triturbo for your input. btw You are the one who inspired me to mess with my lappy

The time right now is not the issue for me, I'll be glad to waste some months to do my new hobby The money... Well its different story because the freaking mobility radeons 4850 is now for 500$ or so.
I think the 3870 will be my choice for now - is it lower TDP than 4850 isn't it?

So if I can lay my hands on such card and can run it sitting at angle i think i will persuit this idea.

Btw there is some portion of free place at the left of hdd bay i think to adapt it for some additional coolling.

P.S. What's your x9100 ? SLGE7 or QHBQ ?

 

HD3870? Really? Get a Toshiba HD4650, overclock it and you'll be there without the extra work.

QHBQ, SLGE7 is gone the way of Dodos.

 

Maybe I just missed something, but I'm looking at:
ATI Mobility Radeon HD 4670 - Notebookcheck.pl
vs
ATI Mobility Radeon HD 3870 - Notebookcheck.pl
and
Mobility Radeon HD 4670 vs 3870

According to notebookcheck and results in 3d mark06 It looks like 3870 should have 20% more juice.
However if gpuboss has it right the floating Point Performance is better in 4670 that i already have.
Thank You for pointing out it to me - the 3870 would be just mod for entertainment and not to gain real performance increase i guess.
Seems i need to find 4850 what can be a lot harder right now.
So now the new question rises for me, what card should i pursahe ?
Should i search for ati 4850 or go for nvidia 9800m gtx maybe nvidia seems pretty much powerfull, but does not support directx 10.1 and shader model 4.1 and what are the odds that it will workn in acer ?

Hmmm... Recently i found sellers that claim only to have SLGE7. All QHBQ auctions seems to be terminated.
Is there is any significant difference between those two ?
I just hope the cpu that is on its way to me is really SLGE7 E0 stepping and seller did not put something with C0, despite all of our correspondence.

 

That's what I said - overclock it and you'll be there.

HD4850 - second best MXM 2.1, the best is 4870, but it is MXM-HE (with the additional power tab) and is pretty picky on the systems. MSI's HD4850 is MXM-III (same connector as ours) and is runs on pretty much everything, given you have the room for it. As for 9800m - that's really old tech.

If your seller is osstore, then he'll try to rip you off. What you'll get will be most likely SLB48 C0, and if you open a case, then you'll probably get "SLGE7" - means you'll get the CPU with this markings on it, but in Windows every program would see it as E0 ES - which means QHBQ with custom labels (that's the story of a forum member which dealed with him). Of course there's third option "SLGE7" C0, now that's a heartless ripoff As for the difference, a handful of forum members claim that even though the final ES sample and the OEM part are pretty much the same, the OEM tends to require a wee bit less voltage for the same speed.
