4 gigs ram

Have I once again been scammed by a computer store ?

I needed to add some more memory. My machine and I are now using the entire 1 gig ram all the time. I went back to the place that assembled mymachine and decided to max out the machine [Asus P4P800 deluxe MB 4 gig ram] from 1 gig ram to 4 gigs ram. In another news group, they tell me XPPro can't access more than 3 gigs ram.
But I've already pre-paid and ordered 4 gigs ram. They're buying the two 512 sticks back.

Am I wasting money on the 4th stick of 1 GIG ram ?
Why would Asus create a board designed for 4 gigs if it's not usable ?

Looks like you're ready for Vista.

This machine will be a smoldering pile of metal chips b4 I stick Vista onit. I can stick Vista on here now without the memory upgrade. That software [Vista] is the most blatant money grab I've ever seen. If it finds support, there's no telling where the monopoly known as M$ will end.
90% of my software and my $400+ video card need to be replaced to installVista. Is M$ going to pay for a $4000.00 upgrade ? I don't think so.

As for the 4gb, I've found with research, the limit on ram is 64 GIGS not4. It just uses ram differently over 2gb. This should make multi taskingmuch faster and smoother. No more stuttering with video capture.

Windows XP has a 4GB address space and that address space has to be shared
with memory used for other devices. So Windows (not just XP but all 32-bit
versions, including 32-bit Vista) can't use that entire 4GB for itself.

How much it can use is not simply 3GB, but depends on what devices are
installed. It's normally a little more than 3GB.

Well FWIW: I wasn't content with the fact that the EXPERTS designed a MB to use 4 GB. And some yahoo in a NG tells me I'm buying 1 useless stick of 1 gig ram. So in addition to asking the seller I found the relevant M$help page. Here's the config.

Memory Support and Windows Operating Systems

The /3GB switch allocates 3 GB of virtual address space to an applicationthat uses IMAGE_FILE_LARGE_ADDRESS_AWARE in the process header. This switch allows applications to address 1 GB of additional virtual address space above 2 GB.

The virtual address space of processes and applications is still limited to 2 GB, unless the /3GB switch is used in the Boot.ini file. The following example shows how to add the /3GB parameter in the Boot.ini file to enable application memory tuning:

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="????" /3GB

and then there's the 64 GIG RAM that XP Pro is capable of using.

>Physical Address Extension. PAE is an Intel-provided memory address extension that enables support of up to 64 GB of physical memory for applications running on most 32-bit (IA-32) Intel Pentium Pro and later platforms. Support for PAE is provided under Windows 2000 and 32-bit versions of Windows XP and Windows Server 2003. 64-bit versions of Windows do not support PAE.

>PAE allows the most recent IA-32 processors to expand the number of bitsthat can be used to address physical memory from 32 bits to 36 bits through support in the host operating system for applications using the Address Windowing Extensions (AWE) application programming interface (API). For information about the AWE API, see the Base Services section of the Platform SDK.
