Works perfectly with two Supermicro X11-based server motherboards. Received all three sticks and Memtest86'd (4 pass) with flying colors. First two sticks have been running the past year and a half almost 100% uptime with no issues whatsoever. Third stick just tested fine on my test bed on its way to joining a second future stick as a migrate our home server to an mATX motherboard (w/Intel's C246's chipset). The Kingston name should be immediately recognizable - and for good reason!
