"Taiwanese manufacturer Silicon Power was kind to send to us three 1GB memory modules declared at DDR3-1333 with CL9 latencies. This type of memory can be considered as budget solution so we weren't surprised with declaration and absence of coolers. Silicon Power used blue coloured PCB and chips signed by ELIXIR. Full specification goes like this: 1333 (667MHz) CL 9-10-10-25, which is by our humble opinion very loosely set timings that leave space for tightening."
