Recently I have bought a pair of G.Skill 8000HZ in the oldest heatspreader:


for my curiorsity, I opened it again:


I wonder why my those chips inside is almost the same as hutch's ballistix:

isn't that a G.Skill HZ???

but the no. on the chip shows -3F only?
that means it is a pair (1000/3)= 667 sticks?

and anyone know what's going on with this pair of HZ, good for OC?
