With the new iMacs finally with us, I wanted to get myself one of them and, while I am at it, maybe replacing my current PC as whole. I tried to find a good comparison online, but somehow Google didn't return anything useful. So...
Can anyone tell me how the new iMac's GPUs against my "old" GeForce 8800 GTS?
has anybody has any problems in Photoshop CS5 with OpenGL still turned on? I remember reading that turning this off can actually yield better performance, but is that even relevant with the 5770 and 5870?
View 2 Replies View RelatedI'm planning to buy a Mac Pro soon (within a week or so), and I'm wondering about the GPU setup. My question: Is there a processing advantage to getting multiple GT120's? I'm running two 30" ACD's so I know I don't need the extra card to support two monitors. But I'm wondering if Aperture, Photoshop, Lightroom, and other GPU intenstive apps would be able to take advantage of having two GPU's? Fyi - I'm planning on the 8x2.66GHz, 12GB ram, 1TB internal (I use drobo's for storage)...so just wondering what would be optimal for my photographic processing (and some videos with the 5Dmk2 camera).
View 2 Replies View RelatedI'm somewhat new to the forums, and found a really good deal for a brand new macbook air (rev.1). I'd like to know if it is possible to replace the logic board in my macbook air with a newer, nvidia-gfx based logic board. As in, will it fit, does the same power supply run it, same peripherals (airport, keyboard, etc) work/interface with it, etc?
View 5 Replies View RelatedAs the title implies, I've got 3 year old G5 iMac sitting as a paperweight at my desk. At least half that time ago the logic board died and I was quoted a repair bill of around $900. I couldn't go with it, but I couldn't decide what to do with it either. I now have to get rid of it and since I know that this model had lots of issues with logic boards I'm hoping some of you will have some good advice.
I got a mac mini out of warranty (core 2 duo 1.83 ghz) that just died on me. I went to the apple store and they sent it in for a diagnostic. They confirmed that the logic board is dead and will be around $350 to replaced. I'm still weighing my options and was wondering if anyone can direct me to a site that sells replacement logic boards to see if I'm better off doing the repairs myself?

Am having a problem with the screen getting "messed up" is the best way that I can describe it. Happens with all different apps running but nearly always shows up when trying to edit a photo in iPhoto. When I make an adjustment there (like sharpening) the photo will turn all red and the system will lock up. This does not always happen, but just most of the time. In other apps, it can result in just messing up that page or the entire screen. I can replace the Graphics card myself if that is what the problem is but is there any way to test it before laying out the $250?
View 5 Replies View RelatedMy 17 inch iMac G5 1.8ghz seems to have died. For a while it's been refusing to power up and then powering up randomly but now it wont power up at all. I've looked on the logic board and reset the SMU etc but I can only get the first LED to light up. I think this means the logic board has died. Is it worth replacing the logic board and can it be done easily myself? Or should I just bite the bullet and pay out for a new alu intel iMac? I'm in the UK btw, any ideas on logic board prices?
View 1 Replies View RelatedMy G5 iMac is getting a new harddrive, meanwhile I had to fire up my older front, slotload IMac (G3), it has 10.3.9 installed and 250GB external harddrive. Unfortunately, this little iMac only has 30GB on board memory. After the 10.3.9 install/upgrade I only had 4GB of available memory. I have looked through just about every file/folder to delete duplicate/unnecessary files but cannot find what has used up the memory. I have a LaCie 250GB external drive, partitioned in three sections at 78GB each; can I install OS X on one of the partitions and work from that for my Photoshop, Illustrator and other graphics software projects?
A few minutes ago a message came up saying that my memory is close getting full and should clear some files to make room. This iMac (slotload) is only rated for 512MB RAM max at 133-333 speed, two 256MB boards (max). Is there a way to get around this and add more RAM, a way to boost it to768MB RAM or even 1GB RAM and still have the system work and utilize the extra memory? Do I need the adapter to run a mirror monitor on the slotload (a 17" flat panel, mac compatible, ViewSonic brand. I have the software to set up the mirror)?
Have an early 20" iMac G5 and the Hard drive started to squeal and then crashed. Tested dive in another iMac and it is definitely bad. Installed new hard drive and the system fails to find it. Formatted it on the other iMac and reinstalled but it still is not seen by the system. Everything was running very well until the drive failure. Took it to an Apple approved store, paid the $60 to be told that the Mother Board was bad. It is hard for me to believe that a disk failure could cause a Mother board failure. 2- 20" iMacs, a 24" iMac, and a new 27" iMac (not yet out of the box.)
View 1 Replies View RelatedI can't seem to figure out how to remove the logic board from a G5 w/iSight that I've been given to have a look at. What happens is that the unit powers on, the LCD display slightly brightens (getting power) but stays dark, and that's it. No beeps, boops or other responses beyond that. If you remove the RAM chips, the LED power lights gets mad and blinks at you, but that's about it. On the board itself I get the two diagnostic LEDs lit. The third never even flickers.
View 3 Replies View RelatedMy iMac died a few days ago. I shut it down the previous night, and then in the morning when I went to turn it on, nothing happened. The screen display doesn't turn on, nothing. I opened it up and did the LED tests, and found that the first one would turn on, but none of the others would. The apple site says to take it to a store and have it fixed.
Now, I bought my mac on December 19th, 2004 ( what a day that was). At the time, I didn't think I'd need to buy applecare or anything. So about how much do you guys think it would cost to replace the logic board? And also, how long would it take to have it replaced?
i need some advice on what to do next, my Intel 24" iMac has failed, diagnosed as a faulty logic board by the Apple Genius. I purchased the iMac in Dec 07, and I deliberately did not purchase the extended warranty as this is a desktop unit, that in 20 months of ownership has never been moved, dropped or transported anywhere.
I have no option than to either pay for the repair - �380 or sell on eBay for spares...!
I informed Apple about the Sale of Goods Act, and they have put the owness on me to prove it was faulty from date of purchase...! They have informed me that I need to visit an Apple authorised service centre where they will run a test and produce a report, which will determine if the fault was there in the first 6 months of ownership.
I've recently been having problems with my iMac G5 iSight after downloading iTunes 9. After a series of freeze-ups, i noticed a visual anomaly appear on my screen. Little hash-marks all over the display were present, and playing DVDs or iTunes visualizer would result in a checkerboard pattern. After doing some research, I found out this was a logic board problem, and it was not uncommon for iMac G5s. However, I kept using my computer for a few more months when it then started freezing two minutes after boot up. I figured it was time to open up the computer and take a look. But after spending the 3.5 hours opening the machine, removing all of the cables and screws, I couldn't find any visible damage on the board. No swollen capacitors like everyone was complaining about. The only strange thing I saw was some discoloration on a few circuits near the USB and Firewire outlets.
I've decided to replace the logic board myself for around $370, and I was wondering about a few things.
1. Would the new logic board come with a processor, or would I need to pry it off of my old one, and re-attach it?
2. Would I need to go through a lot of re-programing and software issues if I replaced my logic board, or would it just start running right off the bat after replacing it?
3. Is this operation worth it? Because I have come to like my iMac after 5 years of use, and I would like to know if fixing it would give me a decent amount of usage before I would simply need to replace it
I have an imac G5 20" that is approximately two years old. About 2-3 weeks ago it started acting a bit flakey....it would lock up on std apps (firefox), it would always lock up after being revived from sleeping etc. I ran the hardware test and everything checked out. Then a few days ago it wouldn't boot. I get the chime, I hear the drive spinning, then the fans kick into high gear and I get a screen with a folder in the middle with a "question mark icon" and a "finder icon" displaying alternatively inside the folder. So I booted up the hardware test dvd and the test failed 27 seconds in with the following error code:
2GMC/2/15: built-in
Logic Board Error Detected
Are there any other steps I should be taking before taking in for service?
My iMac chimes when I press the start button but the screen doesn't come on. It's making a whirring noise so it's doing something. There's a DVD in it but it won't come out when i press the eject button on my keyboard. The iMac also doesn't show up on the network of my MacBook which it usually does. I was having a few problems earlier this week with the screen doing strange things - occasionally turning off, then coming back on. It was suggested that it might be a dying logic board but I tried a Apple Hardware Test this morning but it said no problems found. I have some files backed up but desperately need to get some recent documents off it [I know, I should have backed it up more often ]. Is there any way to get access to the files on the hard disc?
View 19 Replies View RelatedI've got a 20" 2.1GHz iMac G5 iSight on my bench that doesn't power up.
I've tracked down the issue to a grenaded IC on the logic board.
The IC is an 8 pin SOIC chip, to the right of the power connector, just above the ALS connector. It is labeled UE300.
If you know what this guy is, can send me a good picture of one, or can provide me with the numbers from the IC, I can get this mac back to life.
so i've got a system with a fried c2d board. i can pick up a cd board for $150 plus shipping which is good for me. to find a comparable replacement, i'm looking at ~350 and i'm just not feelin that price as im on a budget.
i'm not concerned about the speed decrease as im just trying to get this thing rebuilt.
i understand that there are different heatsink assemblys..vertical vs horizontal. however, i do not know how to tell the difference and i am also unsure whether or not my c2d heatsink will work on this board i receive.
the logicboard possess a t7300 c2d and model # is 820-2279-a, it appears.
i cant find anything on that model, except for on ebay.
and i totally cant find the serial number on this macbook. under the battery on the tray has no serial number listed, and i've read through this documentation [URL]
My son's 17" imac PPC G5 was not booting up. After a trying a couple of things I got it to boot using Disk Warrior and reparing the file directory. At that time I also ran DW's hardware test which said the drive was fine. My son hard restarted it shortly after I fixed it and it wouldn't start up again. Just a gray screen, no apple logo. When I tried to use DW again it told me there were problems with the hard drive and it couldn't fix the problem. I tried to fix the hard drive in target disk mode using Disk Utiltiy and Drive Genius. No luck. So I pulled a working drive out of my Mac Pro and reformatted it and swapped the internal drive of the iMac with it. There were no DIP switches to set. Started up the imac with a Leopard retail disk thinking I would just install a fresh system onto the replaced internal drive of the iMac. Disk Utility on the leopard disk didn't see the hard drive. Now I'm beginning to think it's a logic board problem but I can't find the original disks to do a Hardware test with. Is there some other way to test a logic board? Or some other idea that I'm not thinking of that could be wrong with the machine?

Does the logic board serial number match the computer serial number?
My reason for asking is that 4 months ago my sisters G5 17" logic board supposedly got replaced with a new or refurbished logic board but it seems by the workmanship of the board something fishy is going on.
is a screen shot of my activity monitor. There are 3 differenct dashboard apps taking up tons of my cpu %... I dont know how this happend or what i should do to fix it. This just started happening recently...last time this happened i just ended the processes. But now, it seems to be a repeating issue.

View 24 Replies View RelatedI have a macbook pro 17" 2.4GHz (non unibody). I accidentally applied 220 VAC to DC adaptor terminals and burned the logic board (and also the fuse on the left I/O board).
There were no visible damage on the logic board so I assumed only power input stages could have burned and started to investigate. I removed the battery charger IC, some burned mosfets; and I connected the adaptor plus input to the output of the battery charger block. So the DC/DC converters are now powered from the adapter, as in normal operation. Only difference is that there is no battery or charger stuff.
Now, when I press the power button nothing happens. If I connect the adaptor while pressing the power button, hold it for a while, release it, and press it again, it powers up. (Is this MCEverything from hdd to dvd to fans powers up but not the LCD. Fans start and remain running at full speed. Harddisk powers up but there are no noticable reads. That is, no os boot attempted. The mbp draws around 1.5 A to 1.75 A at 18.5 VDC(not sure if it indicates anything).
I'll do whatever I can to fix my board. I have MSc in electronics, skilled technician friends, and access to lots of tools, parts, and measurement devices.
Is there a keyboard shortcut to eject dvd. I have Mac Mini
View 4 Replies View RelatedI just got a Dual 1 Ghz MDD. It's a big step up from my 500 Mhz Sawtooth!
The problem is that it (supposedly) needs a new logic board. I've been watching logic boards on ebay, but I'm not finding anything with matching part numbers. My logic board has the following numbers:
630-4373 EEHNNW
448F2
KD2370366NFGA
630-4269
I guess the important numbers are the 630-* numbers. Perhaps one it the
'as designed' rev part number, and one is the 'as manufactured' rev part number?
I have the dual 1 Ghz processors; would they work on a 1.25 Ghz logic board? Most of the boards I see on ebay are 820-1476-A, or 820-1308-A.
What's the difference between the 820- boards and the 630- boards?
I don't have a complete service file for the MDD; can anyone email a copy?
I have an older mirrorred face G4 dual 1G.
It recently started acting weird (freezing) and then stopped working altogether.
When I go to start I get 4 beeps followed by 5 flashes of the power light. After that revving fans.
My research has told me that there is an issue with the logic board.
I have checked the 3.6v battery and it is fine. I also have done the following:
reset PRAM (just once mind you)
Pulled all RAM and reseated in different ports and configurations.
Pulled and reset the video card.
Pulled everything else off of all USB ports and FW ports.
I have sice taken the logic board out to have a look.
All looks fine, but I really don't know if there is any way to test a board to see if it's bad, other than putting a new one in.
Also, the red light on the logic board is on. From what I understand that is a sign of over-heating.
Anyway... I was planning on getting my hard drive replaced because it was making that weird noise I talked about and I still am... but. Something else happened to. My friends dog chewed my power cord (just a few bite marks) and it was enough to make the green like really dim so we unplugged it. Instead of trying to fix the cord... we just got a new one but the computer wont turn on!
The light does not turn red green or orange on the plug but the battery light blinks when I unplug the chord (the battery is dead.. all drained i mean).
Me and my mom took the computer to a store that does warranty repairs on both Macintoshes and Windows computers and they said they would replace whatever for free. Like the harddrive maybe the battery if that is what is wrong and the logic board. But well... we kind of never told them my friends dog ate my first power cord >>
I wanted to. but my mom and my friend said they wont replace it for free if we told. I sure hope there is no way they can find out of the 1000 for a new logic board is true. We dont even have that kind of money right now!
But do you think the couple seconds of not enough power from the chewed cord might have shorted out my psu or something?
Im just curious. I know my friend has a friend that took his laptop in for a similar problem... yesterday or the day before.
