Memory capacity
The total volume of all modules of the RAM kit.
Knowing this parameter and the number of planks in the set, you can estimate the volume of one plank. This information can be useful for assessing compatibility with a specific PC: any motherboard has a limit on the maximum volume of each individual bar.
Now on the market there are kits with such a volume of memory:
4 GB,
8 GB,
16 GB,
24 GB,
32 GB,
64 GB and even
128 GB. The combination of several sticks allows you to sell sets of
8 GB (2 sticks of 4 GB),
16 GB (2 sticks of 8 GB),
16 GB (4 sticks of 4 GB),
32 GB (2 sticks of 16 GB),
32 GB (4 8 GB sticks),
48 GB (2 24 GB sticks). 64 GB kits are represented by the following sets:
64 GB (2 sticks of 32 GB),
64 GB (4 sticks of 16 GB) and
64 GB (8 sticks of 8 GB). 128 GB RAM mainly consists of
4 sticks of 32 GB or
8 sticks of 16 GB. And
256 GB and
96 GB (2 sticks of 48 GB each) are not so popular
Memory rank
The number of ranks provided in the memory bar.
The rank in this case is called one logical module — a chipset with a total capacity of 64 bits. If there is more than one rank, this means that several logical ones are implemented on one physical module, and they use the data transmission channel alternately. A similar design is used in order to achieve large amounts of RAM with a limited number of slots for individual brackets. At the same time, it should be said that for consumer computers, you can not pay much attention to the memory rank — more precisely, peer-to-peer modules are quite enough for them. But for servers and powerful workstations, two-, four- and even eight-rank solutions are produced.
Note that other things being equal, a larger number of ranks allows achieving larger volumes, however, it requires more computing power and increases the load on the system.
Memory speed
The clock frequency of the RAM module.
The higher this indicator, the faster the “RAM” works, other things being equal, the higher its efficiency in games and other resource-intensive applications. On the other hand, a high clock frequency has a corresponding effect on the cost. In addition, in order to use the full capabilities of the memory, the motherboard to which the module is connected must support the appropriate frequency.
The most popular are modules with a frequency of
3200 and
3600 MHz - so to speak, universal workhorses. There are also more modest options - for example
2400,
2666,
2800,
2933,
3000 MHz. And advanced for serious tasks -
3866,
4000,
4800,
5200,
5600 MHz. High-frequency modules
6000,
6400,
6600,
6800,
7000,
7200 MHz and more are also provided.
Clock speed
The amount of information that a memory module can receive or transmit in one second. The speed of the memory and, accordingly, the price of it directly depend on the bandwidth. At the same time, this is a rather specific parameter, which is relevant mainly for high-performance systems — gaming and workstations, servers, etc. If the RAM module is bought for a regular home or office system, you can not pay much attention to bandwidth.
