Yes, the 2000 C7 are a complete tri-channel kit, the first 2200 C8 were a dual channel kit- the single green 2200 C8 stock seems to be older, SPD says 30/09, the dc-kit spd says 11/2010- maybe you are right, I havenīt had the time for extensive testing yet, but the stick does well, doing 1116 at 1,63 on first test on funcztion with memtest 86 to see if it works
