Which memory module is good

Recently viewed products

noun explanation

appropriate types

Desktop memory is the most common memory in the DIY market, and the price is relatively cheap. Notebook memory has certain requirements on size, stability, and heat dissipation. The price is higher than desktop memory.

System-specific memory

Notebook manufacturers specify the required memory to ensure the performance of the notebook. It can also be understood that it is a brand memory that has been tested by manufacturers for stability and no compatibility issues.

Server memory

Server memory is also memory. It has no obvious and substantial differences in appearance and structure from ordinary PC memory. It mainly has ECC, ChipKill, hot-plugging and other characteristics, and has extremely high stability and error correction performance.

Memory Capacity

Memory capacity refers to the storage capacity of the memory module and is a key parameter of the memory module. The memory capacity has GB as the unit, abbreviated G. Generally speaking, the larger the memory capacity, the better the system's operation.

DDR3

A computer memory specification that is eight times more energy efficient than the previous generation DDR2 and is currently the most mainstream memory specification. Its frequency ranges from 1066MHz to 2400MHz.

Memory frequency

The memory frequency is the same as the CPU frequency. It is customarily used to indicate the speed of the memory. It represents the highest operating frequency that the memory can reach, in MHz (Megahertz).

Dual channel memory

That is to say, in the dual memory slot of a motherboard , access to two memories of the same memory capacity, memory frequency, and memory brand . For example, the popular combination 4GB * 2, which is two 4GB memories, generally has slightly better performance For a single 8GB memory.

Low voltage memory

Intel ’s new Haswell processors basically only support low-voltage memory. Generally speaking, low-voltage and ordinary memory are compatible with each other.

Heat sink memory

To put it simply, the function of heat sink is added on the basis of ordinary memory, which is commonly known as comb bar memory, which is mainly suitable for overclockers. Because the temperature is high after overclocking and the memory is afraid to burn out, a heat sink is added.

Memory slot

There are three common types of sockets: DIMM, SIMM and RIMM. DIMM is dual in-line memory module; SIMM single in-line memory module; RIMM is the interface type used by RDRAM memory produced by Rambus.

CL delay

It is the CAS delay time, which is the response time of the vertical address pulse, and it is also one of the important signs to measure the memory supporting different specifications at a certain frequency.
