Bearcat Posted September 18, 2006 Share Posted September 18, 2006 Awesome, your sir are a brave soul. Is it possible to determine what Intel chipset is being used? Northbridge and Southbridge? Link to comment Share on other sites More sharing options...
Caslon Posted September 18, 2006 Author Share Posted September 18, 2006 Good thing I removed the logic board, I found a screw loose in the system. Could have shorted it out. It took 15 min. to dimantle and put back together for me to do the posting. I did not look at the chipsets. I will look at the high res photos to see but I think there are heatsinks on them.

Thanks anyways. It looks like the plates with the heat pipes are covering them. Link to comment Share on other sites More sharing options...
bofors Posted September 18, 2006 Share Posted September 18, 2006 I will look at the high res photos to see but I think there are heatsinks on them. It looks like a pair of heat pipes are running off some kind of daughter board, could that be the MXM PCI Express connector? Caslon, would you be interested in helping the MacEFIx86 project extract the Nvidia firmware? BTW which graphic options did you get, the 7300 GT or 7600 GT?

Caslon Posted September 19, 2006 Author Share Posted September 19, 2006 That is the MXM PCI-E card slot. The other set id over the processor. It is a 7300. I would be happy to help. Link to comment Share on other sites More sharing options...
Swad Posted September 19, 2006 Share Posted September 19, 2006 Wow, thanks Caslon. I bet my 20" looks similar, but I'm too chicken to find out... Link to comment Share on other sites More sharing options...
Caslon Posted September 19, 2006 Author Share Posted September 19, 2006 The 20 inch iMac core duo is much more comlicated to dimantle. Link to comment Share on other sites More sharing options...

Caslon Posted September 19, 2006 Author Share Posted September 19, 2006 The LCD has no markings other than a white barcode sticker. Link to comment Share on other sites More sharing options...
equilibriumuk Posted September 19, 2006 Share Posted September 19, 2006 wow brave man, I'm thinking of buying a new imac, altho I'm not sure if it would be better to build a hackintosh. Wonder if it will be possible to use the 7600gt drivers from the 24" imac for a 7600gt in a hackintosh probably not tho Link to comment Share on other sites More sharing options...
Caslon Posted September 20, 2006 Author Share Posted September 20, 2006 Just tried an ATI X700 PC MXM card in my iMac 24. It worked in XP dual boot mode But crashed as soon as mac tried to boot. Have not recieved my 7900 card yet, I'll let you know if it works. Most likely it needs firmware for mac to see it. Link to comment Share on other sites More sharing options...
equilibriumuk Posted September 20, 2006 Share Posted September 20, 2006 Was reading about people using standard pc graphics cards on the mac pro. 'PC' video card ROMs are only 64K, whereas 'Mac' cards are 128k. The reason for this is so that Apple can have full-color and full-resolution boot sequences and boot menu (what you see when you hold down option). Therefore, whatever ends up happening, all PC video cards on a mac (if they run at all) will have a black screen until the OS loads the driver. This hand-off between the video card's ROM driver and the OS driver occurs just before the login screen. (2) Not sure if it's the same for the PC MXM cards or not tho.

guiyoforward Posted September 20, 2006 Share Posted September 20, 2006 do you think the optical drive is easy to replace? I awnt to get one of the cheapo imacs, but I want to have a built in dvd burner... Link to comment Share on other sites More sharing options...
Caslon Posted September 20, 2006 Author Share Posted September 20, 2006 It is easy. Just be careful removing the metal tape arounrd the lcd panel, remove the screws that hold it down and lift the lcd panel and there it is. Link to comment Share on other sites More sharing options...
Mackie Posted September 21, 2006 Share Posted September 21, 2006 Does anyone know what kind of hard disk is in these things? I'm thinking of getting one, but I'd rather not replace the hard disk (added expense, though I could install it without problems). However, if it is a Western Digital model, I *have* to. {censored}tiest brand of hard disk ever. Three of my friends who have iMacs had their WD drive fail on them. BTW...did you guys see that the old 32-bit 20" iMac is selling for around $1100? Great deal. What would be better - a 2 GHz MacBook Pro ($2000), or a 2 GHz 20" iMac CD and a PowerBook G4 (around $2000 together)? I'm thinking the latter.

Caslon Posted September 21, 2006 Author Share Posted September 21, 2006 Mine came with a Seagate 250. I replaced it with a Maxtor 500. The few people I have talked with thet got 500s installed from Apple, said they were Maxtor 500s. SATA II 16 meg cache drives with 7200 rpm only due to heat issues. Also you can upgrade the old Intel core duo with the cor 2 duo processor. So if you get a cheap deal it's worth it. The new 20s are the machine with a newer processor. Sam socket and everything else.

Caslon Posted September 22, 2006 Author Share Posted September 22, 2006 !!!!!!!!!!!!!!!!!!!!!!!!!!!UPDATE!!!!!!!!!!!!!!!!!!!!!!!!!!!UPDATE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Tried the 7900 MXM video card. Don't work. Needs Mac firmware to boot. Any ideas let me know. I guess I will have to stick with the 7600 for now.

I'm thinking the latter. well, the macbook pro is basically a portable imac cd. id say definitely go for the latter unless you travel a lot and do graphic intensive work/game.

Mackie Posted September 22, 2006 Share Posted September 22, 2006 I mainly do graphics work, and it would be good to have two computers. For instance, if I accidently drop my laptop (never happened before, but always a possibility :/ ), and I have the iMac/PB setup, I am $600 in the red and have an iMac to work on. If I drop the MBP, I'm $2000 out and have no other system to use. There are lots of other advantages as well. Link to comment Share on other sites More sharing options...
Caslon Posted September 24, 2006 Author Share Posted September 24, 2006 Apple iMacs are great. There is a misconception though, that they are just laptops with biger screens. They are more like desktops than laptops. For instance they can have much higher heat tolerences so better chips can be used. I have a Macbook pro and several iMacs including the 24 inch Imac. My iMacs are much faster. The design toerences are more like a desktop than a laptop so they will always be less bottlenecks. Link to comment Share on other sites More sharing options...
Caslon Posted September 25, 2006 Author Share Posted September 25, 2006 More on the mod side. I exchanged processors in my 24" core 2 duo with my 20" core duo and both iMacs worked great. So the older Core Duo iMacs can take the 2.33 Core 2 Duo processors. Cool for the people who want to upgrade. Link to comment Share on other sites More sharing options...
