Summary: Somehow got the borad at a better advertised price. Put 2 Xeon L5639'S on this board. 24 core monster machine. Definately worth is. ICHR is sata II 2x LSI ports are sata III. I added a 70 mm fan to the 5520 heatsink and added 2 heatsinks for the lsi ( replaced original ) and the intel chip on the bord. All were burning hot to the touch, wireless thermometer listed around 124 deg. now all under 100. placed board in rosewill RSV‑L4500 with GT AP-15 in front 3 fan bays.
