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!
