The content of this article mainly focuses on how to interpret the server memory RAM parameters and distinguish all kinds of memory. The content of the article is clear and clear. It is very suitable for beginners to learn and is worth reading. Interested friends can follow the editor to read together. I hope you can get something through this article!

Server memory (RAM)

There is no obvious substantial difference in appearance and structure between it and ordinary PC, mainly because it introduces some new and unique technologies in memory, such as ECC, ChipKill, hot plug technology and so on, which has high stability and error correction performance.

The most intuitive way to distinguish server memory from normal memory is to see if the word on the note has an ECC module.

However, the most difficult thing to understand is the parameters on the memory bar!

Perhaps the most troublesome is the RAM parameter. I don't know what all the numbers represent. In fact, these parameters have certain rules. It's very simple. Now let's explore the "mystery" inside.

Identify brands

At present, there are many mainstream brands of memory, but you can actually judge their brands by looking at the letters in front of them, such as:

Samsung: MXXXAXXXXXXX-CXX

Magnesium light (MT): MTAXXAXXXXXXX-2GX

Modern (Hercules, SK): HMTXXXXXXXXX-XX

Samsung memory

The front is very simple, but the complicated ones are the latter ones, such as:

393A4k40BB1-CRC 32G DDR4 2400MHz 2Rx4 EEC REG

Do you look confused when you see this series of numbers?

Don't worry, I'll teach you the parameters step by step.

Product model

In the front part, M393A4K40BB1-CRC is the product model.

Product model

The product model, also known as material, is the identification of a product.

The product model of the memory also comes with all the parameters, so as soon as you see the product model of the memory, the parameters of the memory can be seen at a glance.

Product parameters

32G DDR4 240MHz 2Rx4 EEC REG this string is the product parameters.

Product parameters

Product parameters are the number of performance of the product.

These parameters are the value of memory in the server, and there will be many brands and models for the same parameter.

Further analyze the product parameters:

1. 32 GB represents: memory capacity

Memory capacity

2. DDR4 table: generation

Generation

3. 2400m represents: dominant frequency

Dominant frequency

In addition, it is worth looking at the speed of memory, there are two ways, one is frequency, the other is bandwidth.

As shown in the picture, 1333MHz=PC3-10600 C3represents DDR3,1333 is frequency, 10600 is bandwidth, which means the same kind of memory.

How did the number of broadband come from?

There is a formula: bandwidth = frequency * 8

Do the math: 1333 million 10664 ≈ 10600 if you encounter PC3-10600S, the idea of this "S" is to go beyond, because the actual frequency is 10664, marked as 10600 is a little smaller, and S means it is actually stronger.

4. ECC REG stands for memory type

Memory Typ
