Does anyone has experience of running win xp pro on more than 2GB ram. To my knowledge, win xp pro can address up to 4 GB ram, but can xp pro and apps really utilize 4 GB ram. Will I encounter any problem?

Thanks,
Mike

XP will handle it fine. The current limitations are motherboards.

The maximum physical memory is 4GB running under WinXP, but the maximum addressable capacity will be closer to 3GB.

Here's a good link for accessing how much memory you'll actually need, depending on the use of the computer. Personally, I can't think of many reasons for needing more than 1GB with a WinXP desktop system, and 2GB for a typical workstation.

True, but thats the same with any 32 bit OS. The kernel is able to use all 4GB. Only on a process basis is it less.

Yep. But while I knew that, and you knew that, maybe he didn't know that. :wink:

And finding the link that listed the information without having to type yet another Toey-type novella was like locating the proverbial needle in the haystack.

Whew!

:lol:
