its 64 bit - (first post)
actually this is a dell 9100 (desktop)
I had 2 pairs - 2gb each of ram different manufacturer actually I have 3 pairs of 2gb - any combination has the same results in memtest
1 pair in white 1 pair in black
boots without memory beep errors memtest fails badly on any test with 8gb bios sees the memory
I was running 2 2 gb originally now I have 4 1gb - so each slot is used and it tests perfect
Basically this is a lab setup for a 4 node hadoop cluster. This is the head node and needs the most ram - Id really like to get 8 but Ill live with 4 (if I have to)
So should my kernel support > 4gb? see below
Thank you all for your time!

Hi I have a dell 770 bios sees 8g
Is this a PowerVault 770? Accoding to http://www.dell.com/downloads/emea/products/pvaul/77XN.pdf It does support only 3GB of Ram. Can you please post a complete output of dmidecode. It may very well be a case where the on-board chipset is limited to 4GB address space minus the PCI addres space that leaves only 3 - 3.5GB ofg Ram space
