How to see whether the memory module that comes with a laptop is low voltage or standard pressure

1. The parameter identification of the laptop's own memory, you can check the specific brand and model of the memory module of the laptop through the configuration manual when you buy the computer, and then check it on the Internet, you can know whether it is low voltage or standard pressure, 2. If the configuration manual is lost, you can remove the memory module of the laptop, and then observe the model identification on the memory particles (integrated circuit chips, very small) of the memory module, and then query it on the Internet according to the identification, you can also know whether it is low voltage or standard pressure.

Look at the last letter,"U" is the meaning of low voltage,"M" is the meaning of standard pressure,HQ,mq stands for packaging process,It is not important,It is generally recommended to look at the second digit of the model,On behalf of the performance level,Notebook end 7 is the highest performance,,, the first digit represents the generation,Take my example i7-4700HQ,4 represents the fourth generation,7 represents performance,The following 0 represents the core graphics card model,HQ represents the packaging process,Generally, the end is not U is the standard voltage processor。

If you want to check whether the memory of the laptop is low-voltage or standard-pressure, you can look at the model of the memory module. For example, the model of the memory module is DDR4, which belongs to the standard version of the memory module. But if it is a low-voltage version, an L will be added later, which is DDR4L, which is the memory module of the low-voltage version, the performance and the ordinary version.

There will be a certain shrinkage. However, in order to reduce energy consumption and extend the standby time, this memory will be used. The low-voltage version is generally not seen in today's laptops.

Even a superbook is usually a regular version of the memory.

CPU-Z software.

In general, if you want to detect a memory module.

After opening the main interface of the CPU-Z software, click on the "SPD" option on the page to view the type, frequency and voltage of the memory module.

Generally speaking, for DDR3 memory module types, there is a distinction between standard voltage and low-voltage versions, with the standard version labeled DDR3 and the low-voltage version marked as DDR3L. If it is the standard voltage version, you can see that the memory voltage is.

If it is a low-voltage version, you can see that the memory voltage is.

Nowadays, most computers are equipped with DDR4 memory modules, and the voltage is unified for DDR4 memory modules.

The difference between the standard voltage and the low voltage of the computer memory module is: different boots, different compatibility, and different operating frequencies.

First, the boot is different.

1. Memory module voltage: The computer with memory label voltage can be powered on and enter the operating system at the rated voltage.

2. Low voltage of memory module: The computer with low voltage of memory module cannot be turned on to enter the operating system at the rated voltage.

Second, the compatibility is different.

1. Memory module standard pressure: The memory module standard pressure can be perfectly compatible with low voltage and standard voltage processors.

2. Low voltage of memory modules: Low voltage of memory modules can only be matched with low voltage processors.

Third, the frequency of operation is different.

1. Memory module standard voltage: The operating frequency of memory module standard voltage is higher than that of memory module low voltage, resulting in a higher operating temperature than that of memory module low voltage.

2. Low voltage of memory modules: The operating frequency of low voltage of memory modules is lower than that of low voltage of memory modules, resulting in lower operating temperatures than those of low voltage of memory modules.

The voltage value required for normal rotation of memory is also different for different types of memory, but each has its own specifications, and beyond its specifications, it is easy to cause memory damage.

The general working voltage of SDRAM memory is around volts, and the fluctuation limit does not exceed volts;

The working voltage of DDR SDRAM memory is generally around volts, and the fluctuation limit does not exceed volts;

The operating voltage of DDR2 SDRAM memory is generally around the same level. As for each brand and model of memory, it depends on the manufacturer, but it will follow the basic requirements of SDRAM MEMORY, DDR SDRAM memory, and DDR2 SDRAM memory, and float within the allowable range.

The standard voltage of DDR3 memory is.

Detect with a hardware detection tool.

1. One of the better tools is aida64. Open the software.

2. Point on the left side of the motherboard, and then click SPD. Then tap the memory module in the upper right corner.

3. The memory information is displayed in the lower right window. The "module core voltage" is the voltage of the memory.

Laptop.

Low-voltage memory cannot be interjected.

Different types of memory require different voltage values to work normally, but each has its own specifications, and exceeding its specifications can easily cause memory damage. Notebook hardware requirements are strict, and stability requirements are high. Switching to standard pressure memory increases the power consumption of the notebook and affects the stability.

<><3. After the software is installed, double-click to run the CPU-Z software to open the main page of the software;

4. On the main page of the software, click the "SPD" tab at the top;

5. Finally, check the voltage of the memory module displayed on the page, if it is displayed, it is the low voltage version; If shown, it is a standard voltage.
