CAS latency 15
When running CL15 we went through the same procedure like with CL14. Setting
the memory voltage at 1.20V in the BIOS HyperPi passed at 2'820 MHz. Feeding higher voltage (1.35V) to the memory, makes
the frequency scale to 3100 MHz. Driving the memory at 1.50V allowed HyperPi to
pass at 3'100 MHz.
