DDR_DDR2 Memory Limit in XP Pro?

[Peter Johnston]

Hi There:

Planning on building a new system. Will use Intel only for MB & processor.
Micron or Kingston memory only.

The MB I'm looking at (D925) will take 4 sticks of memory, up to a max of
4GB RAM. Is there a limit to which XPPro will utilise this memory? I've
heard 2GB. If so, presumably the "extra" 2GB is a waste.

Please advise.

THX

Hi,

WinXP's 32-bit version (the current version owned by most users, even if
they have 64-bit hardware) supports up to 4GB of installed ram. The coming
64-bit release will quadruple that.

4 gigs is the limit,but I've read somwhere that when 4 gigs is installed xp
will split this up 2 gigs for some funtion I can't remember right now and the
other 2 gigs for something else.This can be overcome by a registry edit,do
some research on this.

I figured RAM is addressable so if ur PC has 32bit
words, address can have a value of at most 2**33 -1=8
GB.
But if 1 bit is for sign (+/-), then its 8 GB / 2 = 4
GB as u said. But no sign needed for address
registers!!! What's missing bit used for?

Just my 2¢ worth. Larry
Any advise is my attempt to contribute more than I have received but I can only assure you that it works on my PC. GOOD LUCK.

No, 2GB is wrong. XP's limit is 4GB.

However, even though XP can use the full 4GB, installing that
much RAM may still be a waste for you. You get good performance
if the amount of RAM you have keeps you from using the page file,
and that depends on what apps you run. Most people running a
typical range of business applications find that somewhere around
256-384MB works well, others need 512MB. Some people,
particularly those doing things like editing large photographic
images, can see a performance boost by adding even
more--sometimes much more. But very few people will make
effective use of as much as 4GB.

Agreed, with one more RAM preference. I have experienced that using graphic intensive applications .mov I needed 1GB and with that installed XP SP2 is using 326MB with just OL running on my system.

XP can use it, question is, will it do YOU any good.

RAM, Virtual Memory, Pagefile and all that stuff
