XP and 64-bit technology

Tim.T

I'm running XP Home SP1 (I aint bothering with SP2, 75mb of junk! Besides
SP1 works fine). I'm thinking of upgrading to a dual-core AMD 64-bit PC,
with at least 4Gb of DDR RAM. Will XP Home SP1 work on that? Or does it
require an 64-bit-compatible edition such as "XP 64-bit"? I've been reading
about the whole thing but it's confusing. I'd rather stick with Home Edition
if poss. I've checked out both my Zone Alarm Pro 5 and Norton AV 2004 and
they seem to be 64-bit-ok.

Wrong

Besides

Yes. But you won't be able to see quite all of that 4GB of RAM.
According to this doc:
http://download.microsoft.com/download/e/b/a/eba1050f-a31d-436b-9281-92cdfeae4b45/mem-mgmt.doc

<QUOTE>
The physical address space is used to address more than just RAM. It
is also used to address all of the memory and some of the registers
presented by devices. Consequently, if a machine is configured with
the maximum amount of physical memory, some of that memory will be
unusable because some of the physical address space is mapped for
other uses.

So if you want to see all 4GB - or if you plan to use more than 4GB -
you'll need the 64-bit version of the OS.

Home will not have a problem with a dual-core machine. Of course,
32-bit Home won't be able to take advantage of any 64-bit capabilities
of your new machine.

It's your decision of course, but that's a foolish point of view.

Besides SP1 works fine). I'm thinking of upgrading to a dual-core AMD
64-bit PC, with at least 4Gb of DDR RAM.


Note that 4GB is the largest amount of RAM you can run on Windows XP.
There's no "at least" here.

Why do you want so much RAM? The vast majority of users will see no benefit
by going above 1GB, and often even 512MB Only if you run very memory-hungry
applications will so much RAM be of any benefit to you.

Will XP Home SP1 work on
that?


Yes. You won't see any of the benefits of the 64-bit processor, but it will
work fine.

Or does it require an 64-bit-compatible edition such as "XP
64-bit"?


No. If you were to get a 64-bit version of Windows, you would likely have
problems getting appropriate drivers for all your hardware, and you might
not see any benefit anyway, since there are so few 64-bit applications
available.

Neither ZoneAlarm Pro 5 nor Norton AV 2004 will run under Vista.

If you cannot grasp the importance of SP2, why would you even bother with a
more advanced OS?

Well you are Microsoft, aren't you, being an MVP or whatever that means? I
kinda expected that response ;). The only reason I feel that way about SP2
is because of the anedotal evidence of it causing more problems than it
solves. Sure it might work fine for the average desktop user, but for people
like me who use specialised software packages, it can be a different matter.
I have to consider possible conflicts and so on.

I do a lot of rendering using complex 3D modelling applications and render
engines. They can require a lot of processor power and memory, both virtual
and physical; the more the better, in this case. Thus my considering a
dual-core pc, and so much ram.

Who said anything about Vista? Judging by the other replies to my post I may
consider sticking to XP Home.

Again, who said anything about a "more advanced OS"? I'm confused. My
objection to SP2 is based on many anecdotal stories of people having
problems with SP2, that is all. Of course, the replies to my post have made
me reconsider my decision to not download SP2. There are just things I have
to consider.

No. I'm not.

It's an honorary title, given to volunteers like me who have a record of
being helpful in places like these newsgroups. Read here:


Regardless of that, my opinions are my own. Sometimes I agree with
Microsoft's point of view, sometimes I don't.

problems than it solves.


The problem is that you hear about the problems far more than the successes.
When someone has a problem with something, he is likely to come to a place
like this newsgroup, looking for a solution. All those many with no problems
at all don't typically come here to tell us how well it worked. As someone
once said, hang around a transmission shop for a while, and you'll come to
the conclusion that all cars have transmission problems.

I don't claim there is never a problem with it, but in my experience with
it, it has been remarkably problem-free. The few times I've seen problems
with it, it's always been because the person installed it on a
spyware-ridden machine. When you prepare for it properly, there is almost
never a problem.


Sure it might work fine for the average
desktop user, but for people like me who use specialised software
packages, it can be a different matter. I have to consider possible
conflicts and so on.


I have three points in answer to that:

1. There is clearly some risk in installing any software update. The larger
the update (and a Service Pack is a large update), the greater the risk. But
there is also risk in *not* installing the update. Updates fix things that
are wrong and protect you against possible problems, and if you don't
install it, you run unfixed and vulnerable to these problems. The question
is whether the risk is greater by installing it or by not installing it. The
answer is clear to me--it's greater if you don't install it.

2. SP2 is a required base for installing many later updates. If you don't
have it, you are unable to install some later fixes, and you get more and
more vulnerable to problems as time goes on.

3. Your statement above, "Sure it might work fine for the average desktop
user" is a *very* different one from the statement to which I responded, "I
aint bothering with SP2, 75mb of junk!"


I do a lot of rendering using complex 3D modelling applications and
render engines. They can require a lot of processor power and memory,
both virtual and physical; the more the better, in this case. Thus my

OK, fine. Then you seem to be someone who will likely benefit from a lot of
RAM. I just wanted to make sure that you weren't someone who was misled by
the common misconception that the more RAM you have, the better. That's true
only up to a point, and where that point is depends on what apps you run.
