XP will only use 1 gig?

[asdfguy]

I'm looking to build my first machine in a few weeks (once I get all of my ducks in a row) A friend of mine told me that XP will only recognise up to 1 gig of ram. From what I've been reading, that's not true. It doesn't make sence that they would make 4 and 8 gig compatible boards if you couldn't use it. But, none-the-less, I have to make sure. I read the entier FAQ and thiers no mention to his claims. If someone could give me a final say so that I can rest easier, that'd be great. Thanks.

It can use more then 1GB of ram, although i cant remember the exact figure, it does limit it. X64 however, has a much higher capacity for ram

The limit is NOT 1 gig that's for sure, I have 1.25 in one and 2 gig in another.

ok, after reading more about x64, i've come to another question. Windows claims that x64 will be faster with a 64 bit dual core processor. Does that mean a dual core processor (specifcly the AMD 64 X2 4400) will only give you great performance on a 64 bit dual core specific OS? - opposed to XP Pro that i have now?

 

[elmarcorulz]

No, it may give slightly better performance, but for now, XP pro/home is a much better choice, due to lack of working drivers for x64
