SP2 RAM Question

[MK]

Does anyone know if SP2 enables support for more than 3GB of RAM? I can't
find an answer for that on their website - and the only other 'solution' I
have found is that '/3GB' switch which crashed my system hard.

 

[Star Fleet Admiral Q]

Read the site again - the /3GB switch is for "Virtual Memory" not "Physical
Memory" - also unless you run "high end" video or CAD software, you "won't"
find any software on "Desktop" machines that was written to use more than
"2GB" of memory - so using the "3GB" switch on a Win2k Pro or WinXP Pro
Desktop will actually take 1GB or memory from the OS and give it to your
applications that "can't" see it anyway - you end up wasting 1GB as your OS
could really make use of that "1GB" you stole from it and are wasting.
Again, this is all "Virtual Memory" and not "Physical Memory".

Thanks 'Q', but the advice to use the switch in the first
place came to me from an MCSE - which was the ONLY reason
I tried that in the first place. Besides, the issue isn't
how much RAM any given application may or may not use -
it's getting the OS to recognize that it is in fact
installed and available in the event that it's needed.

According to this art,
/3GB is a switch but there is anothe parm /userav=xxxxMB
Win NT and 2000 (some older / other versions don't work)

So the answer is yes but the default parm is 2048, change
it to 3030.

Loooks like phyical memory recongition is not a Win Xp
thing,

If the computer takes the number of slots and chip size,
then we can have up to 4GB
or more than 4 GB.

I recall memory not being recoginised and it was the bios
or the cls settings or the differnces between the chips.

MK,

Windows XP (Home,Pro,Tablet and Media Center) (32-bit Editions) all support
a maximum of 4GB of physical RAM.
This is irrespective of the application of any service packs.

As you have received a number of answers already relating to the /3GB
switch, I will not add any more.

What exactly are you having a problem with ?

SP2 can't help XP get beyond the 4GB limit in x86 architecture.
