Is there a relationship between memory frequency and memory size? What other frequencies are there i

There is no absolute relationship between memory size and frequency, but frequency has a certain relationship with the transfer rate.

Now there are DDR 266 DDR 333 DDR400DDR2 533 DDR2 667 DDR2 800DDR3 800 DDR3 1066 DDR3 1333 Taking DDR2 800 as an example, the bandwidth of the single-channel state is 128bit if it is dual-channel, and the total bandwidth is DDR2 667 as mentioned upstairs.

The single-channel bandwidth is.

Therefore, DDR2 667 DDR2 800 has the identification PC5400 and PC6400 respectively

The previous generation of memory DDR 400 had a bandwidth of .

Therefore, DDR 400 is identified as PC3200

Yes, it is the clock frequency, depending on the access speed.

The clock frequency of DDR 667 PC5400 SDRAM is:

333mhz*2 ddr 2

Maximum bandwidth.

The two brothers upstairs have made it very clear.

I'm also adding that frequency isn't just something that turns.

The frequency here is virtual, invisible, and a cyclical thing. It is generally believed that the higher the frequency, the better, but it is not absolute. After all, the computer is a whole, but it's useless if he's fast.

It's capacity that matters, but that doesn't mean frequency isn't important. Memory capacity refers to the storage capacity of the memory module, which is a key parameter of the memory module. The memory capacity is measured in MB and can be abbreviated as M.

The capacity of the memory is generally 2 times the whole power, such as 64MB, 128MB, 256MB, etc., generally speaking, the larger the memory capacity, the more conducive to the operation of the system.

Like the CPU frequency, the memory frequency is customarily used to indicate the speed of the memory, which represents the highest operating frequency that the memory can achieve. The memory clock speed is measured in MHz (megahertz).

The higher the main frequency of the memory, the faster the memory can achieve. The main frequency of the memory determines the maximum frequency at which the memory can work properly. At present, the more mainstream memory frequency chambers are 333MHz and 400MHz DDR memory, and 533MHz and 667MHz DDR2 memory.

In the figure above, the DDR3 memory frequency detected by CPU-Z should be 1778MHz (889 2). However, there is no DDR3 memory on the market with a standard frequency of around 1778MHz. If the memory is not overclocked, it may be a CPU-Z detection error, which is actually 1866MHz Micron DDR3 memory.

Otherwise, overclocking memory below 1778MHz such as 1600 or 1333MHz. To add memory, theoretically choose any frequency of DDR3 memory (such as 1333MHz DDR3 memory), because most motherboards can support mixed use of DDR3 memory of different models and frequencies, but all memory will run at the standard frequency of the lowest frequency memory. If you want to reduce the compatibility problem caused by the mixed use of different DDR3 memory, you should try to configure the memory of the same model and frequency.

Therefore, you can open the chassis to check the brand and model of the memory, and then buy the same memory by comparison.

It is recommended to use Master Lu to test the hardware, and you can check the memory frequency and brand. It is best to add memory modules of the same brand and frequency to avoid incompatibilities.

Of course, it's the memory capacity comparison and important points Like you take an example, 256's memory runs xp is struggling 2G can completely pull win7 these systems to play games Now the basic memory is 512 1G 256 really can't do anything.

Summary. Hello dear, the nominal frequency of memory is the frequency indicated by the manufacturer on the memory module, and we see that the memory frequency written on the title of the product also refers to this. The nominal frequency represents the highest frequency at which the memory can guarantee stable operation.

The frequencies at which the memory can actually run are determined by a combination of the processor model, the motherboard chipset, and the memory itself.

What is the difference between memory frequency, memory nominal frequency and physical frequency + what is the relationship.

Hello dear, the nominal frequency of memory is the frequency indicated by the manufacturer on the memory module, and we see that the memory frequency written on the title of the product also refers to this. The nominal frequency ratio represents the highest frequency at which the memory can guarantee stable operation. The frequencies at which the internal memory can actually run are determined by the processor model, the motherboard chipset, and the internal memory itself.

The physical frequency is the actual operating frequency, which will vary depending on the hardware.

What is the relationship between the three of them?

The three of them have nothing to do with each other.

Memory frequency refers to how fast the memory runs.

The nominal frequency of the memory is the frequency indicated by the manufacturer on the memory module.

The physical frequency of memory, the effective frequency of DDR400 is 400 2=200MHz, the effective frequency of DDR2-800 is 800 2=400MHz, and the effective frequency of DDR3-1066 is 1066 2=533MHz, that is, which frequency is effectively grinded = nominal frequency change [memory algebra (that is, the number behind DDR)-1].

This gap is not very obvious, and the actual experience is even more minimal, only the motherboard and CPU support up to 3200 frequency will be a little more obvious.

But now the motherboard and CPU generally default frequency is only 2666 frequency, and only when overclocking is set will there be an increase in regret.

This gap is not very obvious, the actual experience is even more minimal, only the motherboard and CPU support to 3200 frequency will be a little more obvious, but now the motherboard and CPU generally default frequency is only 2666 frequency, only the overclocking will be improved.

A memory module is a part of a computer that can be addressed by the CPU and can be read and written.

Memory modules used to be an extension of the main memory in the history of personal computers. With the continuous update of computer software and hardware technology, memory modules have become the whole of reading and writing memory.

When we talk about the size of a computer's memory (RAM), we refer to the total capacity of the memory module.

Memory modules are an essential part of a computer, and the CPU can address the memory through the data bus. Historically, computer motherboards had main memory, and memory modules were extensions of the main memory.

In the future, there is no main memory on the motherboard, and the CPU is completely dependent on memory modules. All content on external memory must pass through memory in order to function.

The respondent is an IT-related professional and familiar with the identification and analysis of IT and computer hardware related products.

Under the condition that all parameters are basically the same, but the frequency is the main gap, then the performance improvement of 3200 compared to 2666 will not be very large, and it is less than 20%, this gap can only be seen by running scores, in actual use, in FPS, it is a few frames, and the user can't feel it.

The same configuration is used, but the frequency of the memory is changed, for the stability of the test, the XMP default parameters are used, and the time is automatically reduced by the system to ensure the stability of the machine, which has a certain impact on the test, but it is not big, and the results are still very obvious) The specific test comparison is as follows:

In the AIDA64's single-pass test, the performance gap was about 20%.

Specific game test comparison:

Red Dead Redemption 2, at different resolutions, at the highest image quality. The actual FPS is basically the same, just 1 frame difference.

<> Assassin's Creed, at different resolutions, at the highest quality. The actual average FPS is basically the same, just a few frames apart.

<> Far Cry, at different resolutions, at the highest image quality. The actual average FPS is the same, but the difference is 1 frame.

Summary: As long as there is no problem with the software or game optimization itself, then the impact of memory frequency on the actual game experience is basically small. So, memory isn't a good option to throw money at for performance.
