OK, dumb question...well not really so dumb!

[MUff1N]

There seems to be controversy over exactly how much memory XP PRO 32 bit systems will support!
Some say 3.2, other say 3.5.
But when looking on the MS support site, they say that XP PRO (not home) WILL Support 4Gbs of installed memory!

"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."

I also have heard something about adding in a line to the boot.ini switch to make it see it?

So what say ye! ???

The reason I'm asking is I'm going to be installing 2 more gigs of the same memory I have installed. At $27 you can't go wrong!

AFAIK, 32 bit windows will not. You need 64-bit. But I've been wrong many times before...

Another opinion??? Please!
Even if it only addresses 3.5Gbs It will still be 1 & a half gigs more than what I have now which my games will be able to use!

Muff1n,
Off topic:
Can you use a Flight stick? I'v got A Logitech force feedback WingMan that just sits in a box. It's a great stick. If you can use it, just pay shipping.

[cloasters]

AFAIK, 32-bit XP will address 3 Gb of Ram.

[bonesaw]

yea it will be like adding another gig and a 1/2

Thanks but no thanks...
I like using my KB & mouse.
It's what I've always used on my PC.
I'd sell it at a yardsale or something if you don't use it.
Thanks anyways!

[MUff1N]

So I see the controversy still continues.
1 says 3 another says 3.5...
I guess I'm going to have to just install it & see for myself.
But I did read somewhere about someone making XP PRO 32 bit see 4Gbs of memory. Nothing above that though.

Anyone else like to chime in?
Better yet, is anyone here running XP PRO 32 bit with 4gigs of installed memory? What does your system say is installed?

Please keep stuff like this in the classifieds only.
Thanks!

Ok, sorry figured because ............well doesn't matter what i figured.
Won't happen agian.

There is a 4 gig limitation with 32 bit OS's, but this will include any video memory so what it sees for system memory will vary from rig to rig..

Reconfiguring the boot.ini for PAE will open up some. With the 975 chipset you can run 3 gigs as well. 2 X 1024 and 2 X 512 together.

This is what I've read as well & I'd expect with the amount of testing & system's you've built you'd know ccp!

According to my graphics card there is 554mbs of texture memory usage with it so 554 -320 = 234mbs of shared memory.
So I would imagine this memory amount will be deducted from the total 4Gbs on the installed memory for a grand total of 3,862mbs.

OR, 320+554 = 874 - 4096mbs = 3322mbs of showing installed memory.

OR, 4096-320= 3776mbs of showing installed memory.

Or am I reading this all wrong? See what I mean! LOL

Would be nice if I knew everything already, but I don't...
Thanks for helping me to understand this clearer.

See mine and Gizmo's posts here.

Kingston 4GB DDR2-1066 HyperX Memory

32bit OS can see 4gb of RAM. I use the term RAM loosely as it includes VGA RAM and cache etc etc.

Thats why some people say 3gb, some say 3.7gb, some say 3.5gb. It depends on other components of your system.
4x1024mb or 2x2gb is a smarter buy than say 2x1gb and 2x512mb to give you 3gb. Because mixing and matching sticks screw with memory latency and clock speed and in SOME situations can even decrease performance.

2x2gb or 4x1024 of matching sticks will give you better speed. 2x2gb is the best option though if you chipset support, IE: X38, 965 and 975. 2x2gb also keeps dual channel and what not.

Also, as mentioned you can enable /PAE switch through boot.ini and make it see the 4gb. It gives you the option to upgrade to a 64bit copy Vista which is easy.

EDIT: Just read your most recent post:

AFAIK this is correct.

[MUff1N]

OK, so my first deduction & calculations were correct...GOOD!
That gives me more RAM!
I do plan on installing another matching set of exactly the same memory as I already have installed. Unless they are radically different in latency I should get good performance out of the 4x1Gbs sticks.
But if I do run into problems on my system with that setup, I'll go to the 2x2Gb setup which is better even for heat reasons! More air in between the memory sticks!
Thanks Rondog for clarifying this for me!
Now I totally & clearly understand!

No worries at all mate. Be sure to run Everest or something similar to test memory before and after upgrade. I'm interested to see how going from 2gb to 4gb goes on an overclocked setup such as yours.

[Samuknow]

As am I...

[ccperf721p]

I've only used one 975 based board and it wasn't that great of a clocker, but from the 965 on filling all slots didn't have much effect on overclocking. If all 4 sticks were capable of DDR1000 it got there, but getting DDR1200 was a little too much with 4G of memory.

Under XP32 I never really noticed any difference between 2 and 4 gigs while gaming.

[Samuknow]

Even with higher resolutions or more candy turned on?

A bit off topic...but I'm among friends...":O}

Why is it that Super PI gives me 13.250 ( As I recall) and no matter what I do never changes unless it wants to go to 13.550 or something close and THEN won't change back?

(Sorry if the number aren't exact, I'm in Fedora..."

I'm not sure I understand. Are you saying no matter what you do, SuperPI gives the same time?
