A. The RAM is DDR4-2666 MT/s memory.
MegaHertz (MHz) means the measure of clock frequency in million cycles per second.
Mega Transactions per Second (MT/s) means the computer transaction rate in million per second
DDR means Double Data Rate.
DDR memory makes an operation on the leading edge and the trailing edge of each clock cycle, so there are two operations per clock. So, a 1333 MHz memory bus speed clock equals 2666 MT/s DDR RAM.
This would often erroneously called 2666 MHz RAM, but it isn’t really. It is 2666 MT/s RAM.
