The 690 is supposed to max out at 32GB and 64GB with a riser. If you've got more than 4GB working, how did you do it and how many GB did you get to work?
This is what's happening wth my memory upgrade attempt:
I just bought 8 sticks of Hynix 4GB PC2 5300f R2. With 8 or 4 sticks of the Hynix -the 690 won't post. When I mix them -4 sticks Kingston in upper white slots, 4 sticks Hynix in lower black slots, BIOS recognizes all sticks, but Win7 Pro 64 only sees 12GB and only 4GB is usable. All sticks pass DELL online diagnostic utility.
My setup is:
Motherboard: DT029
BIOS: A08
CPUs: 2 - 2.33Ghz Xeon
OS: Win 7 Pro 64
RAM: 4GB = 4 sticks 1GB Kingston PC2-4200f R2
Thanks guys
