YES! That Model Imac does have the video cards mounted in a modified PCIe - you can upgrade with other OEM Video cards, for that model of iMac, The early 2008 24" It shipped with the 2600 Pro, and can be upgraded to the 8800 GS

The Apple Part # for the 8800 GS is 661-4664

isn't that only on the new 21.5" and 27" models?

by Chris Green

No, almost all the aluminum iMac's have replaceable video cards, with exception to the low end ones from last year.

by matthewfrey

matthewfrey is absolutely right.

by Ben Eisenman

Can other cards in the NVIDIA 8 series be used? I would like to go to the 8800 GTS if possible.

by Evan Sharp

There may be CPU and cache issues if you do. That card was set for this model - generally, for Mac's, if it fits it works however EFI upgrades and extension (aka driver) hacks may be required. You may not be able to change your OS, or an OS update may wipe out your changes to software.

Yes you can upgrade, your card, for best results stick to the options offered for your model

Update

the correct discription for the 24" Imac Nvidia 8800 GS is MXM HE, I do believe that you can now get a Nvidia 9800 GTX & a Nvidia GT280, both of these are the MXM HE type, I am guessing that as long as there bios is big enough to take the 8800 GS EFI firmware, then that could be an upgrade route, the card would report a slower clock speed (due to the 8800 EFI firmware) , but am pretty sure it will run ok , I no loger possess this version of the Imac , but would be very tempted to give it a try, you would already need to have windows on there so you were able to update the card, I am pretty sure trying to install this with a faulty card woud be a recepie for disaster.

You could always increase the bios size with a 1 meg bios chip, but again am pretty sure the original will be big enough to hold both the Bios and the EFI.

Kenny, you may be very lucky with an alternative MXM Type II card, ie the one you mention, but it will be very limited in its capabilities, the machine or rather what it can handle will be very limited, that is if it works at all.

As mentioned earlier, there is now an Nvidia 9800 and Gt280, I would go with the Nvidia9800 with the Efi from your 8800, I think this would be the safest route.

If you do decide to try what you have mentioned and it works out ok, i would love to hear about it, I have my fingers crossed for you.

I extend matthewfrey's answer. You can even update the Graphics Card of a mid 2007 24 iMac with a Ati Radeon 2600 (not pro) 661-4426 to the Nvidia 8800 gs of the 2008 iMac. That's exactly what I did recently ;)

They have physically different slots, how did you accomplish the swap. I work on Apple, ( My own store ) I have seen both and the card edge is different.

The graphics device is a standard mxm ii/iii board that can be removed and is NOT soldered on to the mainboard. theoretically it is exchangable. Some people argue that other gfx boards wont work because Apple needs to modify the bios/efi then. I dont think so, because a plenty of gfx devices that are not sold by apple run on osx by using enbler software.

Hi, the Nvidea 8800 is only in the 24" imac, the Nvidia 8800 is also nothing like the cards from the other models, if you wish to upgrade your 24" imac (the one with the Nvidia 8800) you have no choice but to replace it with the exact same video card another nvidia 8800. Several reason, if you are interested i will spell them out in my next post.

Can I also just add, if you dont understand what you are taliking about might I suggest that you do not offer advice as it is most off putting, the earlier White Imac had onboard video built onto the motherboard , that is all of them except the 24" 2.1ghs core duo this was fitted with an MXM card either the Nvidia 7300 or 7600.

The aluminium 20" and 24" core duo also have MXM cards but once again not all of them, the odd one was onboard graphics, I have managed to swap cards amongst most of these , except the nvidia 8800 , as the nvidia 8800 was a unique style of MXM, ( all the others were MXM II), I am at this moment in time trying to mod a newer version Nvidia GT130, I am trying to change this card to something beefier like the GT230 or GT250 with more onboard ram, if anyone can help with the EFi for one of these I would be very greatful even if they could point me in the right direction to create my own, I can do the rest once I have it.

the correct discription for the 24" Imac Nvidia 8800 GS is MXM HE, I do believe that you can now get a Nvidia 9800 GTX & a Nvidia GT280, both of these are the MXM HE type, I am guessing that as long as there bios is big enough to take the 8800 GS EFI firmware, then that could be an upgrade route, the card would report a slower clock speed (due to the 8800 EFI firmware) , but am pretty sure it will run ok , I no loger possess this version of the Imac , but would be very tempted to give it a try, you would already need to have windows on there so you were able to update the card, I am pretty sure trying to install this with a faulty card woud be a recepie for disaster.

You could always increase the bios size with a 1 meg bios chip, but again am pretty sure the original will be big enough to hold both the Bios and the EFI.

The 2600 Pro is an MXM II , no way will any other MXM card version work in the slot built for the Nvidia 8800Gs, don't take my word for it, there are plenty of other site's that discuss the compatibility of MXM card versions(you might notice that both logic boards have very different part number).

To be double sure I can confirm that I have tried to make it work without any success.

If you have the 24" Imac with an Nvidia 8800, then there is only the route I have mentioned, if you are lucky enough to have another card in there then you are more likely to have MXM II, you will be able to fit any number of cards in there, but then we are back to the EFI problem

Hi Benedict, make sure the card you are buying is for the apple. As long as your card is made and supplied for an apple machine then alll you will need to do is fit it, make sure you use adiquate thermal compound.

If on the other had the card is for a PC(windows based laptop) then you will need to update the bios on the card with the apple firmware(EFI), if you are not sure about this, email me and I will give you a quote for this work.

Steve,

From you post, I understand that we cannot put ATI Radeon HD 2600 Pro (#661-4663) into an iMac 24" (Early 2008) that originally came with NVIDIA GeForce 8800 GS (#661-4664) as the MXM-HE socket is different from the MXM-II. However, I have read a thread posted in macrumors that a person successfully downgraded his iMac 24" GPU by installed ATI 2600 HD to avoid replacement of his repeatedly failed NVIDIA 8800GS card. His downgrade was done back in May, 2011 and he confirmed that it is still working fine after 6 months.

My iMac 24" that came with 8800GS is also failing as well after almost 3 years of perfect condition. I would like to know if I can install the ATI card before order the part so your confirmation will be very helpful for me. Thank you very much.

by Kenny

he must of been a clever guy as he would need to rebuild the board, as cards are very different, they will not go into each others slots

by Steve

i read a lot of forum said MXM 3 ATI Radeon HD 2600 Pro (661-4663) it is fit on slot MXM HE Geforce 8800GS (661-4664), the different between MXM 3 & MXM HE its just the last power connector on the edge of Geforce 8800GS and there isn't on ATI Radeon HD 2600 Pro.

I do not believe so. That card fails very often and is much more valuable to sell. I personally have 4 white iMacs needing that card. I have attempted that but unfortunately that card was no good.

In theory it should work but would be a lesser card so you may run into issues.

by Cam S

Sorry, NO. The 2006/early 2007 white 24" iMacs used MXM 1 slots, the late 2007/2008 models use MXM 2 slots. The 8800GS in the 2008 24" uses a different MXM 2 that is only compatible with the 24" board that originally came with the 8800GS. I correctly fix all the removable iMac video cards with a USA made IR Rework station. I have fixed all models. The 7300 and 7600 are the only cards that work without modification for your model.

by batsonelectroni

I am aandwcomputerrepair on ebay.( was batson electronics ) Contact me for repair quotes. I warranty the work for 1 year if you send me the whole machine and 6 months for just the card. I replace the thermal paste, thermal pads , and reflow the solder removing the corrosion in the cracked lead-free solder using special cleaner and special no clean solder flux. I also replace the thermal paste and add SMC fan control to lower temps. I use Arctic silver 5 and high $$$ 3x better than stock thermal pads for the Vram and Mosfets around the GPU. If the reflow doesn't work I use leaded solder ball to reball. If all fails you are charged nothing. ( except you pay for shipping to me ) Chris

I have a 20" iMac Aluminium MA877 with HD2600 PRO. Just today I update it with new ATI MXM II HD4650 1Gb from Acer (http://cgi.ebay.com/ATI-HD-4650-MXM-II-V...) card. Physically it fits very well, the PCB design is pretty much the same. But unfortunately after power on the Mac I've got the black screen.

Googling I found that may be I need the EFI update for this card.

Could someone help me to make it work?

If there is an Nvidia 8800 in your machine , then that is the only card that will go into it, I have had all of these imacs, they have different fittings for different cards, any upgraded card will require a flash with the relevent EFi, it may be a wise idea to check the size of the bios on the card first as the EFI requires 1meg most cards are fitted with a 512 chip, this is also possible to exchange, but none of this is easy.

Not true. You can put the other cards in(I have done this and confirm it DOES work flawlessly) but the heat sync is different. If you get the other video card you'll need the proper heat sync for it or mod your current one.

by Cam Stewart

one other snag Cam Stewart, the slots for the card, are different, what did he do redesign the board also, not to mention the heat sink problem, please dont forget, you got to put the screen and bezel back on top of the board, in order to get a picture., after redesigning the board for a 2nd card,. He would of been better just designing his own system, I am sure it would of been cheaper

Ok, so I hear conflicting stories about whether you can or cannot upgrade an early 2008 24" iMac's GPU.

Assuming you can, is the 8800 the limit? Mine has recently worn out. I hear the 8800 is now known for wearing out quickly and getting heat damage. Either I get Apple to repair it or do it myself (as my AppleCare has run out) but I don't want another NVidia GeForce 8800 in there due to its known faults.

You CAN put in the ATI card but the ATI heat sync and pipes will be needed. I have done this to 3 iMacs (24") with success on each. One I had to modify the heat sync by using a hot air rework station to remove the solder from the heatsync piping and move it over. A lot of work but it fixed the iMac!

by Cam Stewart

it will not phisically fit, the 8800 is MXM He , it is not possible to fit any other card in other than an MXM HE, not an MXM 1 or an MXM 2 nor the MXM 3, its a bit like putting DDR ram in a DDR 2 board, NOT possible, good luck

by Steve

Sorry if wrong too, but i think both of U not talk about same card, Steve MXM 3 ATI RADEON HD 2600 PRO 661-4663 ( becareful not ATI RADEON HD 2600 661-4426 for imac 20" A1224!!!), did fit with MXM HE slot they have the same size, U can see on a lot of forum they have try already.

thanks for the answer - i have never done anything like this before and i have one question - if i buy a Nvidia 8800 GS card online do i need to do anything to it to make it work with the mac or should it work fine as is? I've seen some comments about 'flashing' the card but i dont understand what that is or if i would need to do this!

Thank you so much.

Has anyone considered the possibility of using Nvidia drivers from one of the OSX86 projects to make some of these cards work without flashing the BIOS with EFI? The list of compatible cards is here: http://www.tonymacx86.com/wiki/index.php...

In my mind the process would be to first install the necessary kexts (kernel extensions) for the Nvidia support, and then perform surgery on your iMac to install the new card (an MXM HE card, of course).

I have an iMac 24" Early 2008 with an Nvidia 8800gs and I am considering trying this to allow me to install a card with more RAM so that I can run GPU-enabled Adobe apps such as Premiere which require at least 768mb RAM.

I like thinking outside of the box, so please don't get me wrong. The necessity to flash the BIOS on the video card is for hardware compatibility, to provide an interpreter. - If my native language is English and yours is German, we don't communicate well using our native languages - unless one or the other of us understands the other language. With that in mind, Netkas is perhaps the best provider of interpreters for unsupported video cards on Apple computers. Here is a link: http://forum.netkas.org/index.php?PHPSES...

by ABCellars

Hi Noah, I can see 2 main problems, most of the cards on your list are not available in the MXM HE format ( this is not to big a problem as the MXM type will work) second is the heat sink, you may need to build or modify your heatsink to accommodate some of these other card types, in principal many of the other cards will work fine, weather they will run without further problem is another matter. I think the cheaper and only sure way is to go for an MXM He that is designed to accommodate the extra power required to run advanced games or programs. The only sure solution is to trade up and buy another machine.

I have replaced the failed car with the similar years 21" or 24" iMacs as well as a 2006 iMac video card. So there is several that can work. If you go to your local computer recycler/reseller (The Hackery for example in Vancouver Canada) they usually have a card or two you can at least try if not buy. Or they know exact cards that work. :-)
