Just installed 2 sticks of 2GB into my Acer Revo, and when checking out the BIOS it shows Total Memory as only 2816MB, where's the rest?
SOLUTION -
Just for clarity for anyone else with this perceived issue I thought I would explain how the Acer Revo R3600 uses 4GB of RAM. Thanks to Acer support for there quick response to my question.
2816MB Physical Memory + 512MB Video Memory + 512MB PCI Hardware Resources + 256MB PCI Express does indeed equal 4096MB.

Hey Fight Club,
What OS are you on?
If your 32bit, then you'll only ever see about 3GB. That's Windows reporting 3GB, however it may be slighty less. I remember a Win7 beta that reported the exact RAM amount being used, then in a later beta they had rounded it up (so for example 2771MB changed to 3GB).
Cheers

There is no better way then just check it at boot time - there is mem test (computer - not OS) and it should show whole system memory (- reserved for IGP).

Just booted and gone into the BIOS, under product information it shows 2816MB.
Strange!?

Check how much is reserved for IGP. For me it looks like u have 2gb + 1gb - 256 mb for IGP == exacly 2816. But if you are sure its 2x 2gb - I would try booting with just 1 stick (do it for those two) to see if booth alone are 2gb (ie if booth stick are working good).

I have iGPU Frame rate Buffer Size set to 512mb, and each of the sticks show up as 1536MB when installed individually.

XBMC Live has no pae kernel, it can't "see" 4GB RAM.
you could change kernel and install a PAE supported one but please note that there a reports of crashes on music.
I am in a similar situation but had to go back to non-PAE kernel "renouncing" to 1GB RAM because 10.04 pae kernel made xbmc crash and reboot all the time (see my posts on the subject, I later on discovered it was the pae kernel).
Haven't tried with newer kernels yet, don't want to mess again
