Legend
A: Use 115X screws in 2011 mounting pattern for compatibility (ignore manufacturer specs.)
B: Will work if you have memory without heat spreaders
C: Low profile memory will clear the heat pipes better, regular memory may slightly touch or block heatpipes.
D: Fits the socket fine, but sockets are spaced too close for these heatsinks.
