So what are the other "sideffects" created by having Winxp on a MacPro? (apart from the not beeing able to install pci cards, or the cap thing which will be explained)

Windows XP on a mac will only detect the first 2GB of RAM.

I have 3, it only detects 2.

Nobody knows why.

if you want to run windows permanently, i reckon get a pc. If you want to run Mac OS X, and maybe Windows occasionally, get a Mac. Simple as that.


there is a "headless imac" it's called a mac mini...haha

off the topic, but the mini doesn't have any PCI slots, a dedicated GPU, or a >2GHz CPU. It also uses notebook HDDs, which means the drives cost a lot more for a lot less capacity.

whomever is doing the installation and whomever is buying these machines, without mac os on it (if they did it on purpose), should be publicly spanked to humility.

such blasphemy :)

Windows XP can only address 2GB of RAM. It's a known fact, not a Mac limitation.

On topic, I believe the Mac Pro is a better hardware value than Dell. I was pricing out Dell Xeon's for the heck of it and didn't even see an option for Dual Xeon's. IMO, the major reason to buy a Mac is for OS X. Otherwise, go buy a Dell.

Windows 2000 Memory Support. With Windows 2000 Professional and Server, the maximum amount of memory that can be supported is 4 GB (identical to Windows NT 4.0, as described later in this section). However, Windows 2000 Advanced Server supports 8 GB of physical RAM and Windows 2000 Datacenter Server supports 32 GB of physical RAM using the PAE feature of the IA-32 processor family, beginning with Intel Pentium Pro and later.

Windows XP Professional and Windows Server 2003 Memory Support. The maximum amount of memory that can be supported on Windows XP Professional and Windows Server 2003 is also 4 GB. However, Windows Server 2003, Enterprise Edition supports 32 GB of physical RAM and Windows Server 2003, Datacenter Edition supports 64 GB of physical RAM

I stand corrected. I could have sworn that I read somewhere that XP/2000 could only address 2GB. My Mac has 4GB and XP Pro only sees 2GB of it.

That's just a limitation on a Mac running Windows. Real PCs don't have this problem.
At the moment if you want to use Windows with more that 2GB of RAM then you need to use x64. I don't know what it is exactly about it that is different but it removes this limitation.

The Pro has PCI Express Slots. Many (in fact, almost all bar displays and certain controllers now coming onto the market) add-on PC hardware uses PCI or PCI-X, which the Pro does not provide. From the above post I can surmise that EricTheRed71 probably doesn't have access to a 690 as it's not possible for anyone with reasonable knowledge to make such an elementary mistake.

SAS storage is a high-performance storage subsystem (Serial SCSI) that is ideal for true high-performance workstations with high transactional loads which can cover intensive computational use as well as the more normal server-style database uses. This does use a PCI Express controller on the Dells.

And with the number of machines you are supposed to be getting through and being such a long-time Dell user, surely you can get better than sticker price and more in my league?

I don't pretend to be an IT bod but I do think I know a reasonable amount about computers....
I thought that PCI-E was the replacement for PCI-X? It's certainly newer technology... Fair enough if that's not the case. And you're right, I don't have a Dell 690. They were going to be the next workstations we bought but we went for the Mac Pro instead. I was just stating that we had always gone for the top end Dell that was available at the time.

Aaaaand, I never said that we went through a huge number of Dells. We have had only 12 in the last 6 years (still a decent amount) but even then have managed to get a decent deal on every one of them. The Mac still beats Dell on price (for the first time ever!).
Of course if you are talking about huge corporate orders that you are dealing with (which you imply) then surely you could negotiate a better deal with Apple too?

I'd like to know what kind of use you are talking about if you see the need for SAS. If HD video editing & 3d modelling can do without it what actually does need it? We are still talking about workstations here, not servers right?

I still think you are being too down on the Mac. For 99% of heavy users it will be fine. Ours sit here 24/7, slogging their guts out and seem well up to the job.

I won't mention your "superior" attitude.

That's utter nonsense. Just search on how to enable the rest of the RAM in XP.

I know the 4gb limit is all ram like that one person said. So if you have a x1900 or multiple graphics cards it really cuts down the amount. Also this includes page files if i am not mistaken. So check the size of the page file in XP, then add that up plus your video cards, and of coarse how much ram it recognizes, this should add up to 4 gb. But I am not certain as I have never done it myself. Some people just use server 2003 to get around some of these problems but I don't know if anyone has got server 2003 running on the mac pro. I don't think it would be a problem. But who knows.

Thanks. I also won't mention the "stupidity" of comparing a 3-year-old workstation against a new one.

Who did that then? The only workstation I have that is 3 years old is an old Boxxtech AMD sat in the corner looking sad....

Erm...

Why no response to the issue of PCI-E replacing PCI/PCI-X?
Why no mention of the fact that the Dell 690 has 6 (yes, six) PCI-E slots & basically includes PCI-X to support legacy hardware?
Why no explaination of why a workstation (not a server) needs SAS?

Seeing as these are 2 of the main reasons you listed as why a Mac Pro makes a crappy x64 workstation I am genuinely interested in your answers.

How about being a bit less prickly eh mate?

Kinda true, XP "should" be able to see up to 4GB of RAM, but sometimes can only see 2GB or 3GB, the quote is only for XP Pro, NOT for XP Home Edition. And yes the x64 version of Windows should be able to see all the RAM on a Mac Pro.
