none...enjoy the ram that you will never truly utilize unless it's a dual CPU system.....

Windows XP pro (32bit) doesnt recognize more than around 3.1gigs when using a 256mb video card or about 3.7gigs of mem if you use a vid card with less than 256mb of ram... You still have access up to 4gigs with page mem.

How much ram does it say you have in sys properties/general tab?

Well it shows up as 3 GB and I don't think i will have trouble using all of it with EW's software.

Well looks like i found something, I'll try it when i get home.
