No it means in a multi-threaded application that you can have two process both running at 800mhz at the same time. Usually if your lucky you will get about ~60% or better performance depending on the application as opposed to running a single core.

 

But would it be able to run Leopard? Thanks

EDIT: It probably would, right? If it can do two things at once, one of the processors is doing one thing while the other does something else.

 

But would it be able to run Leopard?

Officially - No. Leopard requires a 867MHz processor or greater. One of the main criticisms of Leopard is that it will not run on a Dual 800, even though it is faster than many of the supported models. And I think that the iMac G4 800 was a fairly popular machine, and Apple decided to ditch it for whatever reason. Not a popular move, especially when they dropped 60 models from their support.

However, people have used a variety of hacks to get it to run, both on dual processor machines, and even as low as a G4 500. I suggest Googling to see about caveats etc...

 

Leopard is only meant to run on Apples 867 Mhz or greater.

Some people have installed it on your model through "Target disk mode" and reported success. They warn that you have to have a lot of RAM to do so successfully.

 

If I did manage to get it on, would it run fast with 869 MB of RAM?

 

It would probably run adequately, but I would bump it up to at least 1GB.

 

I just installed Leopard on a 400 mhz sawthoot G4 tower with a 800mhz OWC G4 upgrade. The computer has 1 gig of ram and a brand new 7200 rpm Wester Digital HD. The system was installed before putting the HD in the tower via a firewire enclosure and a iBook G4 with a Leopard retail install disk. Performance ia acceptable but would be probably better with 2 gigs of ram and a fast video card.

 

QuickSliver was a very nice machine.

I suggest you to take a look of this website,

they would provide you some good solutions to upgrade you computer

Well currently I'm not interested in upgrading it because it costs a lot of money and I don't have it yet. I ordered it off of eBay and should get it next week.

Thanks for suggesting though. If it really gets old I will look into upgrading it. I just need a machine that isn't going to be way outdated soon.

If anyone else has used leopard on a less-than-minimum requirements machine please tell me the performance you have.

 

Not to rain on your parade (you sound very excited, good for you!), but what's the Leopard attraction?

There are other cats that will run very nicely on your new system.

 

I meant for the future because I will eventually need to run it. I have Tiger, which I will install on it when I receive it.
