Power Mac G5

[leonzeqiri]

Hi everyone, first sorry for my bad english ,

I found a guy who is selling two Power Mac G5, i couldn't try them but i just saw the pictures.

He said one is Quad-Core other one is Dual-Core
I didn't recognized them from picture taken inside Power Mac.

Inside first PowerMac it's written only G5,
at another PowerMac it's written G5 two times.

One is like this

Another one its like this

Can any one help me which one is the Quad Core.

Respect, Leon.

The quad core is probably the bottom photo. But word of warning...the quad-core Powermac G5's had a liquid-cooling system...and they can be troublesome.

I would also like to mention that there many different models of Powermac G5's. And the cpu's came in four different configurations (depending on the exact model):

- single-processor
- dual-processor
- dual-core
- quad-core

If memory serves me correctly...the 1st (top) photo is of a "dual-processor" G5. And the 2nd photo (bottom)...is what the "dual-core" or "quad-core" Powermac G5's looked like.

MANY people/seller's get the "dual-processor" and "dual-core" models mixed up. So the seller you're working with may actually be selling a "dual-core" PM G5 (or have the wrong photo). Or the seller is actually selling a "dual-processor" PM G5...and NOT a "dual-core". Believe me there IS a difference.

Also...if you see a photo like this:

...it was just an April Fool's joke!

HTH,

Thanks Nick,

So when it's written G5 two times it means that is with 2 processors, and he said this one with 2 processors its 2.5GHZ(is this possible)?

Yes that is possible...there were both a:

- dual-processor 2.5ghz PM G5
- quad-core 2.5ghz PM G5

And just in case...there was NO "dual-core" 2.5ghz PM G5.

So the top photo is probably of the dual-processor 2.5ghz PM G5.

HTH,

p.s. FYI...the dual-processor 2.5ghz PM G5 has a liquid cooling system that can be problematic...and is usually best to avoid. Most other PM G5 models just had a "conventional" air-cooling system via fans.

The reason why the liquid cooling systems are problematic is (besides the obvious "electricity + liquid" doesn't mix rule)...is that the power supply for PM G5's is located in the bottom of the PM G5 case. So any leaky liquid has a good chance of "frying" the power supply.

Ah so the Dual Processor 2.5GHZ is Dual Core not quad yes?

Thanks

 

[pigoo3]

Ah so the Dual Processor 2.5GHZ is Dual Core not quad yes?

No...on both points!

If the top photo above is of the computer with two processors...then the photo is of a "dual-processor 2.5ghz PM G5"...NOT a photo of a "dual-core 2.5ghz PM G5".

As I posted previously...there was no "dual-core" 2.5ghz PM G5.

And the 2nd/bottom photo should be the photo of the "quad-core" 2.5ghz PM G5.

Or put another way:

- their was a dual-processor 2.5ghz PM G5
- their was a quad-core 2.5ghz PM G5
- there WAS NOT a dual-core 2.5ghz PM G5

For simplicity Dual Cores came in 2GHz and 2.3GHz formats and are both air cooled by fans.

The 2.5GHz Quad Core is liquid cooled.

To confuse you even further, there are 2GHz, 2.3GHz, 2.5GHz and 2.7GHz Dual processor machines. These are all earlier than the Duals/Quad, known as a late 2005 model. Make sure if you purchase you get the 2.3GHz Dual Core.

I personally owned a Quad Core 2.5GHz PowerMac G5 up until about a week and a half ago. Neither photo looks correct for the quad core, as it's missing the liquid cooling tubes that would be seen on top of the processor seen here:

Not sure what exactly is going on here, ask the seller to supply you with the full specs and it'll be much easier to pinpoint exactly which models these are.

Hey guys, the guy send me the Serial No. and i checked at A.S.N.I. Decode your Mac's serial number.

and that Power Mac G5 is:

June 2004 model,
2processors -2.5GHZ Dual Core (not Quad)
2GB RAM 400MHz
ATi Radeon 9600 XT 128mb

i think im not buying it cuz it seems slow for these days...

Thank you guys for helping

Respect, Leon.

P.S. I found that it was build in Cork, Ireland, in November. lol

I don't know how many times this needs to be said...but there was no 2.5ghz "dual-core" Powermac G5!!! There was only a "dual-processor" 2.5ghz Powermac G5. There was a 2.0ghz and a 2.3ghz "dual-core" models...but no 2.5ghz dual-core Powermac G5.

This is important...and not just some sort of "techno-speak"...since there are differences between the Powermac "dual-processor" models and the Powermac G5 "dual-core" models.

But at this point & for this discussion it's not really important to discuss further...since the differences may not really be important for your uses/tasks.

Good luck with your purchase,

It is not a Dual Core as Nick says as they were not released until October 2005. It is a Dual processor with PCI-X slots.

It came with the Panther OS X.3 system discs and can run up to Leopard OS X.5.8. See the graphics card ATI Radeon 9600? That is the give away as it is a 4X AGP. Dual Core machines use PCI-E graphics cards.

Nope. the pipes you are commenting on in that pic are part of the QuadroFX4500 cooling system.
the processor cooling pipework is all concealed behind the G5 logo embossed cover

Wow, I never knew that! I always thought that was part of the processor cooling, you learn something new every day I guess, heh. ;D
