How to determine if the memory is compatible, and how to see if the memory is incompatible

The brand and model determine the compatibility.

Generally, after the model is detected by software, you will know what kind of memory it is equipped with.

Or look, people who know how to know the brand and model just by looking at the memory.

The model is the most important factor in compatibility.

Compatibility or non-compliance is related to the electrical performance of the hardware. As for compatibility and incompatibility, in fact, you can only know if you use it, but there are also simple methods, taking memory as an example, the method of compatibility judgment first depends on whether the packaging mode of the memory particles is the same, whether the performance indicators are the same, and then look at the batch number. In fact, the simplest thing is to look at the manufacturer, generally the memory produced by different manufacturers has a high probability of compatibility problems.

Ah, it's very simple, your computer is originally equipped with a memory, you just need to find a memory with the same model as the original, as long as the model specifications are the same, the size can be different, it is best to be the same manufacturer, the people in the computer city are experienced, see more, change more, naturally you will know at a glance, otherwise how do they mix and eat! The memory model is generally SDRAM DDR generation DDR2 three kinds of SDRAM is a very early thing So now there are very few on the market DDR generation is also an obsolete thing But there are still some old machines on the market to upgrade need to use Now the mainstream is DDR2 memory These three memory sockets are not the same So just look at the type of socket to know what type of memory it is The specifications of the DDR generation frequency are 266MHz 333MHz 400MHz These three If there are two DDR memories inserted in the slot, one of which is 266MHz and the other is 333MHz, the system will automatically downclock 333 to 266, using DDR2 generation, 533MHz, 667MHz, 800MHz, 1066MHz, of which 533 is already very few, 1066 is relatively low due to ** high, so there are relatively few mainstream or one, 667 and 800.

There is also the motherboard, if it supports dual-channel technology, the two memories on the socket must be of the same model and specification, but the capacity can be different, preferably from the same manufacturer.

If you understand this, you can easily upgrade the memory.

By the way, the current memory compatibility is generally not bad, as long as the specifications are the same, it can be plugged in, and it can generally be lit.

There are many memory compatibility issues.

Different brands can be mixed.

CPU-Z reads the SPD module.

Parameter information should be memorized.

Purchase memory as a basis.

If the same cannot be found.

Memory manual mode setting.

Specify the parameter values yourself.

Low performance is the standard.

1. Check the appearance of the hardware platform of the memory, the memory is mainly divided into notebook memory and desktop memory. Desktop memory and notebook memory are completely different in appearance and interface, so notebook memory and desktop memory are compatible;

2. Observe the generation difference of memory from the appearance of memory, and distinguish memory incompatibility;

3. Check the working frequency and working power of the previous memory slip without voltage, and the memory of different working frequencies and working voltages is not compatible with Lu Hongqing.

Memory module compatibility mainly considers the following points:

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).
