内存条1.35v和1.5v区别(内存条1.5v和1.35v怎么分辨)

The difference:

1. The working voltage is different

The voltage of DDR3L is 1.35V, the general frequency is 1333, and the voltage of DDR3 is 1.5V general frequency is 1600.

2. The compatibility is different

DDR3 and DDR3L are compatible in most cases, but they are not fully compatible with Intel Haswl processors under the Haswell platform. Intel Haswl for better To reduce power consumption, the memory type it supports is only DDR3L and is not compatible with DDR3.

3. Power consumption is different

DDR3 memory uses a 1.5V working voltage, while DDR3L memory uses a 1.35V working voltage.

4. There are differences in performance

The power consumption of DDR3L memory is 15% lower than that of DDR3 standard memory, and the performance drops accordingly.

Classification of memory

Memory is divided into two types: DRAM and ROM. The former is also called dynamic random access memory. , one of its main characteristics is that data will be lost after a power outage. This is what we usually call memory.

The latter is also called read-only memory. When we turn on the computer, the first thing we start is the BIOS program stored in the ROM on the motherboard, and then it calls Windows on the hard disk. One of the main characteristics of the ROM is that it is disconnected. Data will not be lost after power off.

DDR3 can reach a maximum speed of 2400Mhz. Since the fastest DDR2 memory speed has been increased to 800Mhz/1066Mhz, the first batch of DDR3 memory modules will start from 800Mhz. At the Computex exhibition, we saw multiple memory manufacturers exhibiting 1333Mhz DDR3 modules.

DDR3L In fact, the "L" behind here is the abbreviation of LowVoltage. The full name of DDR3L is DDR3LowVoltage, which is the low-voltage version of DDR3. Its working voltage is lower than the ordinary standard version of DDR3 memory, and its power consumption is higher. Low, but the performance is also slightly lower.

DDR3L low-voltage memory sticks are generally used in notebooks, servers and other equipment. This kind of low-voltage memory stick is rarely used in ordinary desktop computers.

1. The working voltage is different
The voltage of DDR3 is 1.5V and the voltage of DDR3L is 1.35V.
2. Different compatibility
DDR3 and DDR3L are compatible in most cases, but are not fully compatible with IntelHaswl processors under the Haswell platform. In order to better reduce power consumption, IntelHaswl supports memory The type is only DDR3L and is not compatible with DDR3.
3. Power consumption is different
DDR3 memory uses a 1.5V working voltage, while DDR3L memory uses a 1.35V working voltage. DDR3L low-voltage memory saves about 2W more energy than DDR3 standard voltage memory.
4. Differences in performance
Compared with DDR3L low-voltage memory, DDR3 standard voltage memory has about 10-15% better performance.
5. Price difference
DDR3L low voltage memory is slightly cheaper than DDR3 standard voltage memory

DDR3 memory is two types of memory. The standard voltage is 1.5V and the low voltage is 1.35V.
1. Both types of memory have the same frequency and capacity, and the interfaces are also of the same size and standard; the performance is almost the same and can be ignored.
2. The difference between the two is the working voltage. Compared with the same performance and load, the low-voltage version consumes 15% less power than the standard-voltage version. Technically speaking, the low-voltage version is more advanced, consumes less power and is more environmentally friendly.
