How Much Memory Will XP See?

I want to bump my system from 2gb to possibly as much as 8gb of RAM depending on what I find out about XP and memory usage.

I've heard Windows XP Pro will only recognize 4gb of RAM. Does anyone have a definitive answer on this?

Thanks,
Joe
 
Our tech guys at work are building a Windows XP system with 16Gb or RAM. We have two dual-core Opteron 64-bit processors, I think we have to be in 64-bit mode to use all 16Gb of the RAM. But I would guess with one single-core 32-bit processor you could use at least 4Gb. I'm not sure on the 8Gb.
 
XP will only recognize 4gb of memory. There is a 64 bit XP OS out there somewhere (i think it's still in beta, but not sure; could be server OS only); it will recognize more memory; but you will have stability issues mixing 32 bit programs w/ 64 bit OS.

If you do a search on the memory limitations with XP you will get quite a bit of reading material :).
 
Thanks guys. I was afraid this was the case. I guess I'll max at 4gb for now. I'm really reluctant to go to XP64-- as you said Dewman, I hear there are a lot of stability issues. I'm running dual Opteron 254's (2.8ghz) which are 64bit ready. So down the road, when things stabilize, I'll change over (and get more ram!).

When Microsoft releases Service Pack 3 Windows XP will be able to recognize 8GB RAM. I read that in a computer magazine today.

Wow. Now that's great news! What magazine was this in? Is the article online? If so, can you post a link?

Thx,

That article was in a Swedish magazine - Datormagazine #5 2006. This is a paper magazine and is not aviable online. Datormagazin is a big computer magazine in Sweden so i do trust their articles. :)

Their adress is www.datormagazin.se
 
Averdahl-
I was doing a little research on SP3 and they're saying the release won't be before second half of 2007 and will come only after Windows 'Vista' is complete. Looks like we'll be waiting a while.

Thanks for the info.
