Hello folks, in my work I deal with a lot of computer memory. I need to understand labeling of the memory in order to do my job. Specifically I need to know what type of memory I am dealing with based on labeling of the modules. With DDR2 and DDR3 generation RAM memory types were indicated by a letter following the memory speed rating, for example 10600E vs 10600U vs 10600R. I see no such labeling on the DDR4 generation of memory. Is there any way to tell from the memory labeling what type of memory it is? I have been trying to research this with no success, wondering if anyone has any insights?
