Well it can and has been done now that 2Gb+ RAM modules are available. One of the French mac sites reported it not that long afer the release of the G5 if memory serves. As for price I guess that depends on where you go to buy the modules. Do a google search for the article.

I've yet to read about 8GB of RAM having more than a nominal positive effect on performance over 4GB, so for now there really is no point in exceeding 8GB at all, and not even 4GB in 90%+ applications.

Still, some day when the G5 is long in the tooth you'll be happy you have all those slots...

i think the limit is 8 gig per processor, so 16gigs of ram would be the limit you could put in there, but it is pointless and a waste at this point if you ask me though

I do remember reading an article about a group of researchers that regularly maxes out their Macs to 8GB. I can't remember anything else, but I recall they were doing some serious number crunching. And yes, it does make a difference.

So, if you had 16gb or even 8gb of ram, couldnt you just load your entire hdd minus music and stuff onto the ram. That would make your system go really fast.

ONE DAY, Ram will either exceed HDD in space or HDD will be replaced with data on crystal technology which is faster than ram and can hold more data with no errors. :eek: ;) :)

I read something on the G5 having memory controllers that could support 16 GB of RAM, and because the Xserves share the memory controllers with their desktop counterparts, they both can support 16GB of RAM.

Cool, eh?

That is assuming the slot can support to 2gigs of ram which I do not beleive so no it can not.
Looking through the original developer doc for the G5 it does state future compatibility with forth coming 2GB modules so it looks like it does.

Bio-neural Gel packs built into an ODN would work more efficient

Huh...

It's all one chunk of memory shared by two CPUs, not memory that is attached to a CPU. Each processor has to request memory from the Memory Controller's single chuck of memory.

And we don't know what the limit of that is, yet.

Since Apple doesn't publish the specs of that, and I don't have an account at IBM to download specs on their PPC memory controller.

Or are you talking about the AMD chips which actually hang memory off the CPU.

well combatcolin, buy your 16Gig and tell us all about you had no significant speedincrease when surpassing the 4GB ;-)

I think 16Gig might a difference for a server in a large workgroup where everybody boots trough the network and use programs from the server, or use it simultaniously to let the server do folder actions as they did in the firm I used to work, because when we all did put a lot of images in that folder at the same time, we could take a coffebreak together, come back and see wich files wre processed allready & have another coffee with the people who were still waiting ;-)

but I think it will not make a big difference unless you have a lot of applications running at the same time and working with big files...?

The only thing I can see 16gb being usefull for is creating a 8gb ram disk and copying all of OS X over to it, along with whatever applications you use frequently. That'd probably be pretty quick, but I still don't see the need? :confused:
