uname -a is in the original message.
See to be a problem with the board
any memory I put in the black slots will fail with memtest..
damm
I was hoping if the pc booted up with about that annoying memory beep - I was ok... I memtested and it failed

So are you guys saying my kernel should be supporting more than 4gb?
BTW, what the command
uname -a
gives (sorry about trivial thing and if this has been checked already)?

I couldn't find the Dell Service Manual for a 'Dell 770' but I was looking at the Service Manual for the Optiplex 760, and I saw that the way that the modules are paired isn't obvious. It looks like you've got 2 2G memory modules from 64T256020EU2.5C2 (Kingston?) and 2 2GB modules from CM2X2048-6400C5 (Corsair?). I suggest finding your service manual, and make sure that the modules are placed in the DIMM slots and the same vendor RAM is paired with its partner.
It sounds to me like there might just be something weird going on with how the memory is installed. I'm assuming you don't have an artificial limit in the kernel command line or anything obvious like that.
Oh, Ghu.... I don't know about lower-end desktops, but in servers, they *MUST* be *identical*, even to the point of not being able to mix dual rank with quad rank, even if everything else is the same.
