RAM upgrade for intel
Hi chaps I am pondering an upgrade of my mid 2010 27 i5. It has the standard 4gb (2X2) ddr3 1333 sodimm. I need to be certain of whether I am restricted by dual channelling. Do I need to buy in pairs? Or can I leave my 2X2gb and add a single 4gb stick?

Re: iMac noise
I know that early core duo intel macs and iMac G5 macs look the same on the outside but had different stuff in the inside, but is there a way to take the fan and heatsink from a core duo iMac to an iMac G5 to remove all of that noise? -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

I imagine that it CAN be done, the question is would it be practical? And that answer would be no. The heatsinks are certainly different, and likely the fan too. Removing all that noise would result in an overheated G5, unless you built your own liquid cooling system somehow. But that too is going to be impractical. The G5s used in Apple desktops is a relitively inefficient CPU, it uses a lot of electricity and creates a lot of heat. To deal with the heat you need a lot of air flow, which is where the high noise level comes from. The G5 Power Macs used many fans running at low rpm to keep the noise down, but in the iMac there isn't room to do that so the fan(s) have to run at higher rpm. Also the Power Mac as a less restrictive air flow path than the iMac, which helps cooling and creates less noise.

Re: RAM upgrade for intel
Just put two and two together. The GF's mac pro has 6gb. 2 1 gb and 2 2gb, she said she had to put it in, in pairs.

Because the real issue is, do I really want to. If it does work, I can forget about dual channelling, and so, really, what's the point. At best, the existing 2x2 may work in asymmetrical dual channel mode. To further your question, the determining factor is chipset and not processor. At least, that is my understanding.

And the reason Apple never put a G5 in a notebook or Mac Mini is because the chassis is too constrained for adequate cooling, that and battery life in a notebook would be abysmal. Given how many fans there are in a G5 Power Mac I would expect that the G5 iMac would have more than one fan too.

Re: iMac noise
The PowerPC 970-970fx CPU is inefficient COMPARED to today's processors, but this processor even today provides effective computing power. Don't forget, this processor has different instruction sets and architecture code than the intel processors, so different things may result in different reactions. Maybe it's just the G5 working overtime to beat today's intel processors. The iMac G5 will always be the fastest, to me. The PowerPC 970-970fx processors, although despite their heat, are still by far my most favorite processors of all time. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Re: Mac OS X Lion 10.7 is no longer a rumor!
I have a question The iMac G5 is perfectly useful... but no new version of Mac OS X supports it anymore. It is a powerful, 64-bit computer that will last until 128-bit computers start peeking through the markets I wonder if it would be a good idea to dual-boot it with Ubuntu systems because Ubuntu still supports PowerPC with their newer system releases.

It is a powerful, 64-bit computer that will last until 128-bit computers start peeking through the markets I'm not going to defend the way Apple has gone from extremely long product support to extremely short over the past few years, but your logic isn't quite right. The 1984 Macintosh was technically a 32 bit computer, and while I would love to have one for my collection, it is in no way useful for 90% of the things you could do with the newest 32 bit computers (except, of course, word processing, where the lack of internet and multimedia capabilities give it a huge advantage). The G5 series is still a very useful line of machines, but they are getting older, and just because they are 64 bit doesn't mean they will never be obsolete. Secondly, according to what I understand about 8/16/32/64/128 bit computing technologies, there won't be 128 bit home computers for a very very long time, since they don't offer much improvement over 64 bit for most purposes. Also, you can clearly see the trend in the history of home computing: 8 bit was common in the late 1970s before it was replaced by 16 bit PC compatibles in the early 1980s, then 32 bit became common in the late 1980s and early 1990s, and it wasn't until the past few years that 64 bit became really common. based on that, 128 bit home computers probably won't show up for another 20 or 30 years. Of course, lately companies have been jumping at any chance to purposely obsolete a device or technology, so I could be wrong.
