It says that windows xp home 32 bit will not recognize anything over 3 gigs of ram.

What will happen if I put in 4 gigs?
will it run and just not show the other gig or will it make my system unstable?

thanx for any replies

what other hardware will you be running?

and no, your system won't be unstable, just unable to use all of the memory

You can install 4 Gb, but it will only recognize 3.8Gb... So use it, if ya g0t it.

the amount it will recognize will vary (always less than 4GB phyiscal memory), there have been some discussions on this recently.

I run two XP 32bit systems with 4GB RAM, one recognizes 3.7 the other one 3.9

It will be fine.  I run 32-bit XP and have 4GB of RAM.  With my system configuration I see ~3.17GB of the 4GB total.

I already have 2 gigs installed and I manually set the timing when I put them in.

when I install the other 2 gigs should I manually set the timing or just stick them in and not worry about the timing?

thanx again for all the replies

You'll probably want to set the RAM timings back to auto, so they get the initial settings from the SPD, then re-adjust the timing with all four sticks installed.  The timings and voltage necessary to operate 4 sticks may be different than just two.

Hmm mine can only see 2.75 odd.
This makes me wonder about my vista 64 and 4 GB Ram troubles...

the amount of ram you can use depends on the rest of the hardware you have

In another thread recently some one mentioned it depending on the type of ram (or it might have been the speed? I only know so much about computers...) I belive he said that with more modern ram 32 bit systems only see as low as 2.7 while other types were as high as 3.8?

Lemme go see if I can find that thread.

Edit: yeah from other thread:

Actually 2.7 gigs or depends on the bandwidth of the memory. For example PC 3200 can get up tp 3.8 and PC 6400 can get up tp 2.7. So it depends on what you have.

Not this hot potato again.

OKAY, I'm only going to say this once.

32bit XP DOES support 4GB of physical RAM - whether it's PC3200, PC6400 or whatever.

However, in all systems, some memory addresses are 'mapped' to IO (meaning they're used to communicate with any peripherals, video card, sound card, and do on).

So, because the 32-bit address space is exactly 4GB, if you install 4GB of physical ram, the IO mapped addresses will hide some of the physical addresses.

How many addresses are hidden in this way varies from system to system, so there is no single maximum amount of ram that will be available to windows.

In fact, if one were to build a system that didn't use memory-mapped IO, windows would see all 4GB - but that's only in theory - all modern PCs use memory-mapped IO.


Now to answer the OP, yes you'll see some improvement going from 2GB to 4GB physical RAM, but not as much as you get from going from 1GB to 2GB, unless you do a lot of graphics/video/audio editing, or other tasks that require large amounts of RAM.

OMG!

This is exactly what I knew would happen. Which is why I said this:

If you don't have a clue what you're talking about, please don't offer advice to people in a tech forum. It's just going to confuse people.
Which is exactly what has happened. People have been confused by it.

The reason 32-bit OS's can't see 4GB of memory is very simple. They need some of their 4GB maximum limit to talk to hardware. The more hardware you disable, the more RAM the OS will see.
