Can XP detect 4GB of RAM?

[Eagle101]

Hello all!

Well i recently purchased a 2GB stick to go in my laptop with my other 2GB stick, so that it totals to 4gigs. I right clicked properties my comp, and it says 3.0GB and on DxDiag is says 3070MB availiable.

Re: Can XP detect 4GB of RAM?

The windows on your laptop is currently 32-Bit and you need to be running a 64-Bit OS in order to recognize your 4 gigs.

Hope that made sense

Re: Can XP detect 4GB of RAM?

32bit OS's will only a maximum of roughly 3.25gb due to the way memory is reserved for I/O devices. You can force PAE's, but i'm not sure how or whether they work.

You'll need 64bit

P.S. If you are at Newcastle Uni, you should be able to apply for free Microsoft software. That's how i got my Vista Business 64bit free.

Almost any Uni with decent computing facilities has this. If you haven't been told about it already, ask the IT tech guys for more info.

Yup, i believe it's called "Microsoft Software Assurance".

It's basically MS's way of making sure you use their software in the future, not that ghastly open source stuff :p

Nah am not at Uni now, Summer Vacation! will go back by the end of Sept08 though. Hopefully i will be upgrading to vista by then.

Tell me is it a good idea to buy a Vista OS 32Bit on my Rig not laptop or should i go 64bit?

laptop problem is solved thanks to dr0matik ;D yes i do have a 32 bit, man was i a nub not realizing that lol cause i already know that 32 bits wont recognize my 4gigs as 4 but as 3.5gb.

Go 64 if you can.

Yeh 64bit is ok now since most of the driver issues and whatnot have been sorted out.

Re: Can XP detect 4GB of RAM?

im using 64 bit xp and contrary to popular belief 99% of applications work for it the only two i cant get to work is windows live (windows suck balls), and rome total war but you can bypass the OS check and it works fine after that

supports 1000gb+ of ram

Re: Can XP detect 4GB of RAM?

8 TB of "user mode" virtual memory address space per process. A 64-bit program can use all of this, subject of course to backing store limits on the system. This is a 4096-fold increase over the default 2 GB user-mode virtual address space offered by 32-bit Windows.

[...]

Support for up to 128 GB (Windows XP) or 1 TB (Windows Server 2003) of random access memory (RAM).

Boom.

Boom.

That's 64bit not 32bit.

Uh... yeah. I was just pointing it out to everyone, in particular Death Merchant, but I didn't want to look like a **** by rubbing facts (if you can call wikipedia facts nowadays) in his face.
