I am currently thinking of changing to DDR2 1200 ram and have found 3 I'm looking at but they are not listed in the "NVIDIA nForce for Intel Recommended Memory List" so I was wondering if anyone has or knows anyone who has used any of these in a "XFX MB-N780-ISH9 LGA 775 NVIDIA nForce 780i SLI Intel Motherboard" and what if any problems they had getting them to work at specs.

OCZ2FXE12004GK/OCZ Flex EX
OCZ2FX12002GK/OCZ Flex XLC
OCZ2B1200LV4GK/OCZ Blade Series

Added this one because I.
I've read in several places it rocks an dis easily OC'able.
