Legionhardware wrote a guide about memory to compare the different types, frequencies, timings, capacity and more.
Recently I have noticed an increase in technical support questions concerning the topic of memory. Often users are confused about memory timings, frequencies, bandwidth or simply what memory to buy. This article will cover all these topics and more, starting with what memory is and why we need it. Memory is also often referred to as RAM (Random Access Memory) and acts as a “memory” buffer for the computer, allowing it to think quickly. The hard disk drive (HDD) should not be confused with memory as they are two completely different things. Hard drives are larger more permanent forms of storage that are also far slower than memory.
