addition to some motherboards also need to do in the BIOS settings, General motherboard specifications will be described. When the system has implemented dual-channel, some motherboards will be prompted at post, you can take a closer look. Since the self-test is faster, it may not be visible. So you can use some software to view, many software can check, such as cpu-z, relatively small. In the term "memory" there is a "channels" project, if the word

The difference between memory DDR2 and DDR3

At present, we use the main computer memory is DDR3 memory, DDR4 memory is already in the research and development phase, has been successful, predicted 2014 total mass production instead of DDR3 memory, today, a netizen asked the editor such a question: the difference between DDR2

What is the difference between memory DDR2 and DDR3

DDR3 is expected to be born next year The speed is soaring! AMD's AM2 Interface K8 architecture Processor introduced support for the highest DDR2 800, and Intel released its long-awaited Conroe processor on July 23 and carried out the largest "terrorist attack" in history, and the computer market appeared to have entered the DDR2 800 in 2006 ahead of time. RD600 supports 1500Mhz front-end bus overclocking,

data to be written to the storage queue. In a read pipeline, the required data arrives after a fixed number of clock frequencies after the read instruction is issued, and the waiting process can issue additional instructions. This delay is called the wait Time (Latency), which is an important parameter when purchasing a computer for storage.SDRAM is widely used in computers, from the initial SDRAM to the subsequent generation of DDR (or DDR1), then

How to identify SDRAM and DDR memory

(1) In terms of appearance, the common SDRAM memory strips and DDR SDRAM memory strips are almost indistinguishable, but careful observation will find many differences. The SDRAM is often said to be DIMM memory, it has a common (8

Differences between RAM, SRAM, SDRAM, ROM, EPROM, EEPROM, flash memory

Common Memory Concepts: RAM, SRAM, SDRAM, ROM, EPROM, EEPROM, flash memory can be divided into many kinds, which can be divided into RAM (random access memory) and ROM (read-only memory) according to the loss of the power-down data, where the RAM access speed is relatively f

First, we know that the memory controller needs to determine a p-bank chip set before addressing the chips in the set. Therefore, a chip selection signal is required. It selects a p-bank chip set at a time (the number

Pre-charge operationTo address another line of the same l-bank, you naturally turn off the original line. Re-release the column address.Turn off the original line to pre-charge (to overwrite the entire memory and then close the action line)That is, the pre-charge contains two

What is SDRAM memory

SDRAM is the abbreviation of "Synchronous dynamic random access memory", meaning "synchronous dynamical random Memory", which is what we call "synchronous memory", which uses 168-line structure. In theory, SDRAM synchronizes with CPU frequency and shares a clock cycl
