A:Answer Note that CL (CAS Level) 38 is a rather tight (high performance) timing. For instance the standard Crucial parts have CL 46, not 38. I take that to mean you don’t want to upgrade with the Crucial 5600 MHz parts (please correct me if someone knows this to be wrong). The Crucial parts are getting pricey ir unobtainium anyway now that Micron announced it is nixing its once-great Crucial division. If anyone actually owns one of these, could you do us potential (Best) Buyers a favor and open the bottom and tell us the exact RAM parts that it comes wit from the factory? Then we can extrapolate to the bigger sister parts.
