Intel Mac :: Core Duo 216GHz Memory Upgrade?
Mar 11, 2012
I have 20" iMac core duo 216GMZ w/ 1GB and want to upgrade memory, how much can I install? Have 2 512MB DIMM. Does the new RAM have to be same memory capacity for both DIMM? I wanted to upgrade from 10.6.8 to Lion and don't have enough memory which prompted the inquiriy. The Lion installer said I need to have min 4GB. How much memory in excess of 4GB is advisable for Lion to be a smooth running OS.

I would like to upgrade the memory on my mac pro to 8gb (4 x 2gb) plus the original 2gb (2 x 1gb) that comes standard for a total of 10gb. I have looked on [URL] and the prices range from $198.99 to $799.99 for 8gb (4 x 2gb) kits. The Omni Technologies Optival is mighty tempting at $198.99 and I see that OWC has 8gb for $269. What do you recommend? Is Optival any good? The reason I an adding 8gb is for multi-tasking video/audio etc.

I recently purchased a Mac Pro and it's awesome. BUT I wanted to know is it possible to swap out the processors for maybe 2 quad cores or even 2 3.0 GHz processors and if so, how would you do it? Is this possible? (pictures of the motherboard are attached)

is it even possible to upgrade an old dual core powermac g5 to a quad core or even an 8 core.
I have a dual core one and i really need to upgrade to a quad or even 8 but it is so expensive to buy a whole brand new one and i was wondering if there was a way to just get a new processor and more ram or what not.

I have a mid 07 iMac that I just upgraded the memory in and now it wont reboot. I had two 1 gig and switched to two 2 gigs. I can replace one of the 2 gigs with one of the original 1 gigs and it will start and shows in "about this mac" that I have 3 gigs??? Then take the 1 gig back out replace with the other new 2 gig and wont reboot again.

If you have the guts and a few thousand dollars, why wait for Apple to release it?

My one week old iMac 2.7GHz Quad-Core Intel Core i5. first started problems by not goping to sleep even when I forced it.
I shut it down using the shut off button and unplugging it from power for more than 5 munites.
I turned it back on, it does the usual startup chime and then gray screen. I have restarted twice from the shot off button and still getting the same result.

I'm just going to order a new Mac Pro and noticed that it was slightly cheaper to order the base dual processor model and buy the 2.93GHz hex cores myself. A couple of questions arise:
Will my AppleCare still be valid or will I have to keep the 2.4GHz Xeons if I need to return it to Apple for any reason?
Is there market for the 2.4GHz processors?
Can I upgrade to the 3.33GHz processors or will this not work?

I scanned the posts and didn't see this question, but honestly I didn't read all 20K + messages.I bought in late 2005 a dual 2.3 G5, about 6 months before the Mac/Windows combination came out. Does anyone know if I can upgrade or is it too costly to do so compared to buying a new machine.

The ivy bridge processors are coming out soon (or may already be out). I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?

I noticed on the Apple refurb site that Mac Pros from 2010 have either 4 or 8 memory slots. Is there an easy way to tell how many memory slots a computer will have? From what I have seen it looks like the quad core machines will have 4 slots while the eight core machines have eight slots. How many memory slots are in the hex core machines?

I bought a refurbished Mac Pro (8 core) from the apple store and added 4 Gb (2x2Gb) to the 2 Gb tht came installed. I am having a peculiar problem in seeing all four of the memory modules. The only setup that shows all 6 Gb of the memory is to have the modules in the following format: a) 2Gb modules on Riser A, positions 1 and 3 plus 1 Gb mods on Riser B positions 1 and 3; b) 2 Gb and 1 Gb mods on Riser A positions 1 and 3, respectively, and the same on Riser B.
When I put them in the logically (and aesthetically better) intuitive configuration of paired mods in positions 1 and 2 of each Riser, I can only see the modules that are in position 1 of each riser. Is this something expected in the new MacPros? Is there a disadvantage of keeping this configuration? I note that a memory installation video on line stated that the way memory is installed in the early 2008 Mac Pros has changed. Does this issue result from that change?

my 2.66 ghz Quad Core Mac Pro has 6 gig's of memory. I always have several application's open at the same time. I've got Aperture 2 which is using 632 mb of memory but sometimes it goes over 1gb. Iphoto is using 300 mb, I've got firefox open, the New York Times Reader, Rhapsody's online player, Apple's email client, Itunes, etc. Do you guys think that 6gig's of memory is enough? Is more memory recommended? Would that 2 gig's of memory make a difference?

I plan on buying third party ram for the new Mac Pro. I want to have a minimum of 12GB of ram, possibly up to 24GB. How would you configure it, and is the sweet spot 12, 18, or 24, and not 16?

Anyone try to put more than 4gb of memory on a dual core MacBook? Do you have to have the same amount of memory in each slot? I've only got 2gb and am running Lion, which slows everything down.I got a 2gb and 4 gb from OWC but the folks at the Genius Bar tell me that the MacBook ishould have no more than 4gb and that the memory slots need to be equal.
