Are RAM 800 and RAM 1333 compatible?

1. No, first of all, the socket interfaces are not the same, and they can't be plugged in.

2. Then the power supply voltage of the 2nd generation memory is different from the 3rd generation of memory, and finally the memory automatic frequency adjustment is limited, not infinite up or infinitely down.

3. Memory module.

It's about algebra, using cpu-z software, looking at the memory column, there are types in it. There are DDR1 DDR2 DDR3 in the memory, depending on how many are inside, it is the number of generations. As long as it is of the same generation, it is compatible.

The 800 and DDR2 1333 are of the same generation. If used together. 1333 can only be used as 800.

The highest frequency of DDR2 on the market is only 800, and there is no 1333, and 1333 is DDR3, and if your motherboard only has both D2 and D3 memory, then if you plug in the D3 frequency, the motherboard will automatically reduce the frequency to your D2.

Look at what motherboard you look at, on the reviews I watched, Taiwanese motherboards can support both D2 and D3 (of course, memory slots are provided), but motherboards like Onda miserable red are not good, 2 with 3 with you can't turn on the machine together. Asus, Gigabyte, MSI, and Intech can all use DDR2 and DDR3 at the same time, and there is no such thing as automatic downscaling.

Of course not, first of all, the socket interfaces are different, you can't plug it in, and then the power supply voltage of the 2nd generation memory is different from the 3rd generation memory, and finally the memory automatic frequency adjustment is limited, not infinite up or infinitely down.

One DDRII and one DDRI, except for some special boards that support at the same time, generally the board will not support at the same time.

It is not compatible and cannot be supported at the same time.

First, the main frequency is different.

1. Memory 1333: The main frequency of the memory module is 1333MHz.

2. Memory 1600: The main frequency of the memory module is 1600MHz.

Second, the running speed is different.

1. Memory 1333: A memory module with a running speed of less than 1600.

2. Memory 1600: A memory module with a running speed greater than 1333.

Memory 1333 and 1600 have different speeds and different bandwidths! 1600 faster! If the memory of different frequencies is used together, 1600 will automatically drop to 1600 frequency, and there is a small difference in data throughput performance, which is not felt in general applications.

Theoretically, the higher the frequency, the higher the storage rate, and vice versa. For example, if you want to pump water in a pool, the capacity of the memory is equivalent to the size of a pool, then the speed of the pump is the frequency, the higher the speed, the greater the amount of water in or out of the unit time, or the shorter the pumping time of the same amount of water.

Therefore, the 1600 is more chunky than the 1333 one that needs to process data within the working bandwidth. But in the actual operation, you don't feel very good.

Memory is the bridge between other devices and the CPU, and all programs in the computer run in memory.

It is used to temporarily store computing data in the CPU and exchange data with hard disks and other devices. As long as the computer is running, the CPU will transfer the data that needs to be calculated to the memory for calculation, and when the calculation is completed, the CPU will send the result out, so the performance of the memory has a great impact on the computer.

The structure of a memory module.

First of all, look at the structure of the memory, the memory in the picture, this circuit board is the PCB, the black pieces pasted on this circuit board are memory chips or memory particles, and the gold in the lower row is the gold finger, which is inserted into the memory slot on the motherboard. There are also capacitors soldered on the memory PCB, and if the capacitors are dropped, the memory will not run normally.

There is a gap in the middle of the memory gold finger, which is a foolproof mouth, which is a design to prevent memory errors of different generations from being in the memory slot, so as not to burn out.

The difference between 1333 and 1600 is that the speed is different and the bandwidth is different. The advantage of the 1600 is that it is a little faster.

with a bandwidth of 10600.

with a bandwidth of 12800. In terms of bandwidth, it is about 22% larger than 1333. But the actual speed difference is very small. The main thing is to match the motherboard. The advantages are not noticeable in everyday use.

3. In the DDR3 era, when memory of different frequencies is mixed, the motherboard will automatically reduce the frequency. When 1333 and 1600 are used together, they will automatically drop to 1333. Therefore, it is common in most cases.

The difference between 1333 and 1600 is that the speed is different and the bandwidth is different. Without overclocking, the 1600 is a little faster.

with a bandwidth of 10600.

with a bandwidth of 12800. In terms of bandwidth, it is about 22% larger than 1333.

3. But the bottleneck of the current computer is not in the memory, in the case of other configurations, if you don't overclock, 1333 and 1600 are almost not congratulated in daily use.

The transmission standard of 1333 is PC3-10600, and the frequency is 667, but he transmits data 2 times in a cycle, so he is equal to 667x2, which is 1333.

The transmission standard of 1600 is PC3-12800, the frequency is 800, and the data is transmitted twice in a cycle, so 800x2 is actually equal to 1600.

The maximum bandwidth of 1333 is:

The maximum bandwidth of 1600 is.

Start with your own configuration.

If your motherboard (some motherboards require a 22nm CPU to host 1600) supports 1600 memory, you're good to go. There is no need to force it if it is not supported. Overclocking doesn't make a noticeable difference.

In a word, if you have a conditional choice, don't force it if you don't have it.

With a bandwidth of 1600>1333, high-frequency memory has a lot to improve system performance. It mainly depends on whether your platform supports it or not.

In general, there is a slight difference between the 1333 and 1600 frequencies in terms of data throughput performance. It is not felt in general applications. However, when using processors with integrated graphics cores such as Intel's i3 and AMD's APUs, it is best to use a higher frequency memory module, which will enhance the graphics performance.

Generally, the 1333 frequency is sufficient.

I'm the third. I know I don't want to be recommended. But let's waste some % points.

That is, you can't use the frequency of 1333 at all. Of course, as long as your motherboard supports it, it is recommended that you still buy 1600. 1600** cheaper.

And high frequencies are also a trend.

Basic use doesn't feel anything.

The win7 rating will be a little higher above.

Civilian, 1333 is enough, of course, in terms of cost-effective, it is better to choose 1600.

I used 4G single 1333 ADATA win7 rating actually playing wow Battlefield 3 or anything I don't feel anything. The memory is also adequate. Of course, if you can upgrade to 4G x2, the performance will be improved.

But I can't feel it. The gaps are very small.

1333 and 1600 refer to the main frequency of the memory module [the same type (currently mainly DDR2 and DDR3, DDR3 is 1 times stronger than DDR2), the higher the better, the faster the storage speed].

Personally, I don't think there's much difference.,If it's not for enthusiasts who want to top everything.,There's no need to use 1600 memory.,The general configuration 1333 is completely competent!

The maximum speed at which you can run is not the same.

One can run up to 1333MHz and one up to 1600MHz

1333 and 1600 memory modules have the following differences:

Compared with the 1333 memory, the frequency is 267MHz higher, while the bandwidth is 20% higher, and the speed is about 8% faster.

2. From the perspective of working mode, 1600 memory is more mature and perfect than 1333 memory.

The memory and 1333 memory have different bandwidths and therefore different speeds.

Because both memory modules are DDR3, they can be mixed, but the frequency of 1600 memory will drop to 1333MHz in the mixed case.

The memory frequency is different.

It can be used together, but the frequency can only be used at 1333MHz.

The selection of memory basically depends on three major items.

The first consideration is the main frequency, because the memory of different main frequencies is plugged together or the motherboard does not support the motherboard at all, which will cause compatibility problems.

For example, the motherboard supports 800, 1066, 1333 and the like, which does not mean that the motherboard can be plugged in at the same time.

For example, the first one is 800MHz, and the second one is 1066MHz. The result is that the 1066 drops to 800 running, which is a "bucket effect" of how much your motherboard supports, which are detailed on the motherboard's box and instructions.

Moreover, it is better to have the same memory brand, otherwise different processes used by different manufacturers may be incompatible even if the parameters are the same.

The second is capacity, although the larger the capacity of the memory, the better. But to be honest, the average user uses 4G of RAM, which is more than enough. Moreover, the 32-bit WinODWS system can only support the memory capacity.

No matter how big the system is, it won't be recognized. Therefore, if you want to upgrade to 4G or more, you must use a 64-bit system. You can right-click on "My Computer" and select what are the bits of the writing system in "Properties".

The third is CL delay, which is a term that cannot be explained in three words and Mandarin. A brief description is as follows.

CL reaction time is another indicator of balanced memory. CL is the abbreviation of CAS latency, which refers to the latency time required for memory to access data, and simply put, it is the response speed of memory after receiving instructions from the CPU. The general parameter values are 2 and 3.

The lower the number, the shorter the time it takes to react. This is a problem caused by the production process, so it is a factor that must be observed when shopping for branded memory. (represents the quality of the manufacturer).

Another interpretation is that memory latency can basically be explained as the amount of time the system waits for a memory response before entering a state where the data is ready for an access operation.

1333 and 1600 memory are mixed, and in most cases it is possible.

Because of the DDR3 memory manager, when the memory of different frequencies is mixed, the high-frequency memory will be automatically reduced to low-frequency use. This greatly improves the stability of memory mixing.

Before DDR2, the memory speed is by SPD, that is, it works according to the frequency information of the memory memory in the SPD, so that the mixing of memory at different frequencies will cause different memory to be used on the same motherboard at different speeds, resulting in unstable performance. After the DDR3 generation, the frequency will be automatically reduced, although the speed of high-frequency memory is reduced, but in exchange for stability, it is still worth it.

Of course, this also has something to do with the motherboard. The brand-name motherboards of big brands will generally do better and have high stability. The motherboard of a small factory, due to its technical strength, is worse and may still be unstable.

Can be used together. Just like DDR2's 533 and 800, they can be mixed. It's just that the main frequency of the memory is 533, and the main frequency of 800MHz cannot be played. The same is true for the mixing of 1333 and 1600 memory.

The bus frequency is not the same, theoretically 1600 is better than 1333.

Desktop memory module DDR3 1333 2G 1066 compatible Compatible actually means motherboard compatible:

1. It means that the memory frequency compatible with the motherboard is 1066MHz.

2. DDR3 memory frequency is generally MHz.

3. Generally, the motherboard is compatible with DDR3 memory to 1066MHz, and the upward compatibility is 1600MHz.

Theoretically, as long as the memory of the same generation can be compatible with each other, that is to say, a DDR3 1333 and a DDR3 1066 memory module can be inserted into the motherboard at the same time, but if you use it at the same time, the frequency of 1333 memory will automatically roll back to the frequency of the lowest frequency memory (1066MHz).

This means that the memory can also be used on motherboards that support 1066Hz memory.

The higher the frequency of the same type of memory, the faster the speed and the better the performance. Motherboards that support up to 1333 can run on 1600 memory, but will automatically downclock to 1333; Because the memory frequency is backward compatible, it is not possible to have a motherboard that supports a minimum of 1600.

They are all third-generation DDR memory, and the motherboard of the same generation of memory is compatible, so the motherboard that supports 1600 can of course be on the 1333 one;

Motherboards that support 1333 can also go up to 1600

To put it bluntly, the same brand of memory module, in terms of performance, 1600 is slightly faster than 1333, but in general, the difference is not very big.
