What is DDR4 memory?
DDR4 memory is a new generation of memory specifications. The biggest difference between DDR4 and DDR3 lies in three points: the 16-bit prefetch mechanism (DDR3 is 8bit), the theoretical speed is twice that of DDR3 at the same core frequency; more reliable transmission specifications, and the data reliability is further improved; the operating voltage drop is 1.2V .
DR4 has higher performance, larger capacity, stronger data integrity and lower energy consumption.
DDR4 has more than 2Gbps per pin speed and lower power consumption than DDR3, which can improve the performance and bandwidth by 50% while reducing the energy consumption of the overall computing environment. This represents a major improvement in memory technology and energy savings of up to 40%.
In addition to performance optimization, more environmental protection, and low-cost computing, DDR4 also provides a cyclic redundancy check (CRC) for improving data reliability, and chip parity check to verify the integrity of "commands and addresses" transmitted on the link. In addition, it has stronger signal integrity and other powerful RAS functions.
Many hardware names are usually named after the chip model, and each chip model has its own dedicated driver, so as long as you know the chip model used by the hardware, you can find the right driver. For example, if your graphics card is named: "AMD Radeon RX 580", while actually the core chip model used is: "Radeon RX 580", then enter "Radeon RX 580" or "RX 580" to find the driver.
If you have a laptop or an all-in-one PC, you can also use the product name to search, and then go to the download page which has all the drivers for this machine (including: graphics card, network card, sound card, etc.). For example, if your laptop product name is: "Dell A6-9220e Inspiron Flagship", then type "Dell A6-9220e" to find all the drivers for this laptop.
Search steps:1. Enter a keyword in the input box and click the "Search" button
2. In the query results, find the driver file you need, and click the download button
• Can't find the required driver files?
• Don't know how to find driver files?
• Unable to download driver files due to unstable network?
You can try using this driver file finder. The method of use is very simple. The program will automatically list all the driver files available for your current system. You can install drivers for devices that do not have drivers installed, and you can also upgrade drivers to the latest driver version for devices that have already installed drivers. Click here to download the driver finder.
