Note that Speed Select (SST) SKUs were originally suffixed with the 'C' suffix but were later changed to 'Y'. Some of the early engineering samples that are circulating around still suffixed with a 'C'. | Note that Speed Select (SST) SKUs were originally suffixed with the 'C' suffix but were later changed to 'Y'.
