I ordered a retina iMac with only 8GB with the plan to upgrade it myself. I just saw these in a shop (and priced competitively with online prices).
Does anyone know if these would be compatible with the new retina iMac?
All the specs seem to match, DDR3 1600 SO-DIMM 1.35V, it's just the CAS latency is different (CL9 vs CL11). Also would the faster CL make a difference performance wise?
