I thought it was already dual channel ram in the g5's, I might be wrong though, but I don't think so. I'm sure that you need to install memory modules in pairs, so that makes a dual channel system..

Klaus

Yup, it's already dual channel.

We go with the flow.

At one point people "complained" that a lot of news came from MacBidouille. Meanwhile, Appleinsider was out-of-action for a couple of years.

I'm sure in a year or so, someone will post "does MacRumors get all its news from xyz.com?"

arn

Thank you arn for explaining, that makes sense.
 
Also, anyone else notice the new MB is green plastic, rather than the cool blue colour they are now? Not sure why they would move to a green board - kind of bland and PCish. Though I guess it is probably less expensive. 😕
 
I dont see why the space in front of the processors would be empty in top picture with the plastic cover on, if something was supposed to go in there, that just seem crazy.

The square of new bare metal space seems a bit of a strange colour too. Looking through the old G5 manual I'm thinking these are fake.
 
I do not think that this is a dual, triple, or quadruple processor machine. The reason: RAM slots. There are 8 on the current dual machines, but only four on the current single processor G5. This says to me that the new line-up will not be duals. I am still at a loss as to what that gaping empty space in the front of the machine houses. No dual optical drives is a bummer, but not a deal breaker for most. Also, no extra room for hard drives (where they traditionally go in the current G5) is a bummer. I guess none of this really matters to me, as I just bought a Powerbook, and have no money left.

There is a metal slot underneath the ram slots. This looks like the place to slide in the fans. When you remove the fans in the current G5, you can see similar slots for the fans to connect to.

This is a service manual. They are trying to show a procedure, so parts may be removed. This is not an apple comparison photo. There could be all kinds of parts removed to illustrate whatever the manual is trying to show.

OR it could be that this revision keeps the old case (with the same slots for fans, etc.) but eliminates the fan in accordance with the changes in the motherboard. Interprete it however you will.
 
<Dances with joy>

A Dual 3ghz G5 machine would be friggin awesomwe!! 😀 I'm curious about the RAM slots...maybe they are hidden 😛

There are now 2GB DDR ram sticks available, maybe apple things we don't need more than 8GB RAM..

BTW someone said that intel can't have more than 4.x GB ram in their mobos, which is untrue. Intel's mobos use some weird RAM emulation thing where they have 42bit addressing (someone do the math).. anyways I'm pretty sure that means intel's mobos (even on 32bit processors) can go higher than 8GB (which is apple's artificial max).

It's 48 bit addressing and it uses segmentation, not emulation. Intel processors since the 486 can address up to 64TB of RAM. It's done using 32bit addressing space with 16bit memory i/o space to map areas (segments)

OS X also uses 48bit addressing at the moment, not 64.

I wonder if Apple is hiding liquid cooling under that larger shield?


I highly doubt that we will see liquid cooling anytime soon in an off the shelf average joe computer. Water cooling is very much an enthusiast product. There are too many risks involved, if pump dies, a hose breaks, fittings come loose, not topped off with the right kind of water or even at all etc. your processors and anything else water cooled are trashed. It would be nice but at this point I don't think it will ever be practical unless there are some major advances in the technology. Sure there are systems like I.C.E. that shuttle uses but that’s simply a transfer pipe to move heat to where the fan is about 2” away not a true water cooling system. There is wishful thinking though.

I am fairly certain the machine is dual channel already but the reason it has to be installed in pairs is the dual processors. Dual channel setsups don't require you install in pairs, it only has to match if you want to take advantage of the dual channel performance.You have to match the quantity of ram for each memory bank for the processors. So you cant have 4 gb in the 4 slots for the first processor and 512 mb for the other processor. The 1.6 does not have to be installed in pairs it can be installed in single sticks.
 
Could this just be some clever photoshopping of the system that was built by the guy who fitted a PC into the G5 case?

Well, what are the chances that this could be a dual core, dual processor system? Now that would be wicked!

pretty much impossible. Moving to a dual core setup would be huge, and I'm not sure apple could get IBM to keep that quiet. Dual core is a major revision to the chip design, probably would even get a new processor designation altogether. Quads are, in my opinion, much more likely than dual core chips at this point,a nd I don't think quads are likely.

Sorry to burst anyones bubble, but the service manuals have not been updated - I checked them about 20 minutes ago, and they are the same as always. Attached is a screenshot of the current service manuals page, and the current service manual I downloaded 20 mins ago.

I would be nice if this was the new G5, but it's not true 🙂


I second that this is fake i just downloaded a g5 service manual from apple and it is identical to the one i had a week ago

😕

There does seem to be a lack of original content. 😉
It's a site that reviews rumors from other sites, including AppleInsider, ThinkSecret, MacBiddoulle, etc. and sometimes gets its own rumors.

What is the smallest size DDR2 DIMM you can buy?
 
My 2 cents

It is real, or it is fake (not a photoshop job). Some one stripped there G5, put there PC mobo inside, and got a "A" in metal shop to make the that donkey size heat sink.

The only thing that might be photoshopped on it is the G5 logo itself onto the heat sink.

Or like I said, it is a real pic, some apple loser let the cat out of the bag, and apple has got a secret liquid cooling system going inside that tank with the new 975.....i only wish though.

Looks like a new SINGLE CPU heat shield, to me. (AI speculates that it's a new dual shield, but it only says "G5" once--and I think Apple likes to show off that there are two in there.)

If that means the lineup's not going all-dual, I approve: the lowest PowerMac can then be cheaper than possible with duals.

As I said over at AppleInsider, I think you have hit the nail on the head. The heatsink enclosure most likely hides the empty space left by a single processor. Think about it. Remember the specs proclaimed by that French rumor site a couple weeks ago? They mentioned the entry level model would have a single processor and a single media bay while the other models would have two of each. Apple could use the existing case design (which they already put a lot of work into) for the single [Powermac 7,3] and use a revised case design [PowerMac 8,1] for the duals. What do you think
 
hehehe... take the linked image out of your post, you're wasting my bandwidth! 😡 🙄 😉

Okay, I STILL am getting a broken image link on that image.

Ironic: You're hosting the picture on your RCN webspace. And I'm at work right now (RCN technical support).

I wonder at the 8 ram slot, 8 gig cap that seems to exist when they could go so much higher... Is there are market for a sixteen ram slot machine?

I just noticed that. Maybe the fans are larger in this version and fill up the rest of the empty space as well. Which is quieter? A large, slow moving fan or a small, fast moving one?
 
That's my point, that screenshot was from the current service manual, to prove that they haven't been updated with a new model. Also, I'm not the general public, the service manuals are not available to the general public as you state.

I think we are talking Updated vs Updated and Published here. You're still at least a couple rungs down the ladder.
