different mobo hv different design, some mobo slot 1-2 is master, slot 3-4 is slave; some mobo slot 1-3 is master, slot 2-4 is slave. so its totally depend on which mobo u using.
for the slave slot it will working at higher latency, so u need to loosen the CL to make it stable.
and 1 more is if u OC ur RAM, if it still unstable at high CL , mayb u need to increase Vdimm for it..  |
