Just avoid ram with the big "teeth" (cooling fins)
from reading reviews the big cooling fins dont really do anything for cooling
in real world applications
i would avoid the Corsiar Vengeance for example
the XMS3 are good
looking at your moboon your link
and looking at the CM 212+
you look pretty good
since it is a ATX size board
looking again at this link

if you look at picture of 212+ on mobo (bottom picture-third from left)
the fan would drawing off your ram and blowing towards back of case
okay was just searching toms
looks like the 212+ is good with ATX cases and mobos
just not mATX cases and mATX boards with tall ram like the Ripjaws
to be safe keep the Ripjaws in the farther away slots
2 x 2gb ripjaws
2 x 2gb standard low profile ram
I dig some digging and the closest in CL and voltage were
these Kingstons are nicefor the price

they are CL9 and your Ripjaws in combo are CL8
so your ram will drop to the lower timing of the Kingstons
but you wont ever notice the difference
unless your are going for world record memory benchmarks LOL
I want to be honest and tell I havent built a P67 board
so I hope some of the Sandy Bridge owners see this thread
