1333 1066 800MHz memory which is better The difference is there

The performance of memory depends mainly on the size of the memory cache and memory bandwidth. The cache size of the memory is easy to understand, that is, 512MB, 1GB, 2GB, or the memory multi-channel with multiple memory to expand the memory cache. Secondly, in terms of internal coarse bandwidth, this is related to the equivalent frequency of memory, 800MHz memory belongs to DDR2 memory, 1066MHz memory DDR2 has, DDR3 also has, 1333MHZ is DDR3 memory.

DDR2 memory is 4x faster memory, while DDR3 memory is 8x faster memory. The bandwidth of DDR2 800MHz memory is 800MHz x64bit 8=, the bandwidth of DDR2 DDR3 1066MHz memory is 1066MHz x64bit 8=, and the bandwidth of DDR3 1333MHz memory is 1333MHz x64bit 8=.

1333 is better, the main difference is that the frequency is different, and 1333 is DDR3 generation, 1066 and 800 are DDR2, but DDR3 also has 1066 this frequency, but it is not used much.

800 1066 is DDR2 memory Of course, DDR3 1066 also has it, and 1333 is also DDR3 The difference between DDR2 and DDR3 is that the frequency is higher and the performance is stronger The memory is of course the higher the frequency, the better So 1333 has the best performance.

The two slivers of 1333 and 1066 can be used in one slot, it is a new model, it is fast, and the frequency of 800 is very low, but there are still many 800 slivers,

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. The memory that matches the motherboard is the most suitable.

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.

4. The combination of each motherboard and CPU has a specified standard configuration of the memory frequency, which is the best, and do not blindly pursue higher frequency frequencies.

In terms of my experience, the gap is not very big, almost no feeling. CPU, memory capacity, memory frequency, and hard disk read speed all determine the speed of response. If everything else is of high standard, a slight difference in one indicator will not make a big difference.

For 1333 and 1600, the difference is negligible.

The 1600MHz memory module is only 1333MHz for the following reasons:

Usually referred to as frequency reduction is the relationship between two high-frequency and low-frequency memories with close frequencies next to each other, and the high-frequency ones will automatically be lowered to the low-frequency ones. For example, if you put one DDR3 1333 and one DDR1600 on a board that supports 1600, the 1600 will be downclocked to 1333.

The maximum memory frequency supported by the motherboard is less than the frequency of the memory module, and the memory module is restricted by the motherboard to reduce the frequency.

Although the DDR3 1600 memory on the market is nominally rated to support 1600MHz frequency, many of the existing standard voltages are unable to reach 1600MHz, especially some XMP overclocking strips, many of which are overclocked with 1333MHz particles and voltage, and become 1600MHz, the preset working voltage of this memory module is often higher than the default voltage value of DDR3, and does not meet the DDR3 1600 specification of JEDEC. Up to JEDEC DDR3 1333 preset parameter values are supported.

Because your other memory is 1333, it lowers the frequency of this memory. But this one is 1600

What's your CPU? It should be that your CPU does not support it, if so, then you need to manually adjust it in the BIOS.

Hello:1; Fake memory 1600MHz

2；The motherboard is fake 1600MHz

3；CPU fake supports 1600MHz

4；CPU-Z false positive.

Hehe, 1333 won't be too far behind!

If it's convenient, report the CPU and motherboard models!

Good luck!

1. Theoretically, the memory frequency of the CPU is 1333 faster than that of 1066, which will not be obvious in actual use.

2. The memory frequency of the CPU refers to the maximum speed at which the CPU can read memory data.

3. If the motherboard only supports the memory frequency of 1066, then there is no difference between the memory frequency of the CPU is 1066 and 1333.

4. The main frequency of memory is the same as the main frequency of CPU, and it is customary to be used to indicate the speed of memory, which represents the highest working frequency that can be achieved by the memory. The memory clock speed is measured in MHz (megahertz).

It can be used, the computer motherboard will automatically downclock to 1333MHz, as long as your computer can recognize it, it will not matter, 4G becomes 8G, theoretically speaking, you will run large software faster.

If you usually only use about 2GB of memory, the improvement is not obvious.

This is the same as the highway, when there are a lot of cars, 2 lanes become 4 lanes, which becomes a lot faster, but if 4 lanes are enough, your car can only run to 160km, and then it becomes 8 lanes, which is useless. Depending on the size of your car, you can only run up to 160km h
