Desktop Memory

With the help of some software tools, you can detect memory settings from Windows XP. These may include the CPU-Z, SiSoft Sandra and EVEREST. In addition, SiSoft Sandra and EVEREST are equipped with the efficiency verification solution to further validate whether or not the performance based on the SPD settings is achieved.

This question depends on the computer user you are, what programs you plan on running on the computer, and how many programs you have open at a given time.
We suggest:
Internet、office work:4GB
Common games、audio and video playback:8GB
Hardcore user、advanced digital image processing:16GB or more

When users wish to over-clock the memory module, they must manually adjust relevant parameters, such as clock speed, working voltage, CL, tRCD, tRP and tRAS from the BIOS. Therefore, unless the user has rich overclocking experience, he will need to try different combinations in order to find out the best settings for the module to display its optimal performance. Therefore, it is time- and labor consuming, especially to beginners.
As a solution, NVIDIA extended the SPD by adding more parameter combinations to the unused space, about 29 bytes, in conventional SPD. As long as the supported motherboards are used, the BIOS can automatically detect the optimal module settings to easily release the performance of modules. This feature is called the EPP, Enhanced Performance Profiles.

Please confirm that your motherboard supports the memory specification.

DDR3 and DDR4 are not compatible because they are different in both pin count, arrangement, and signal definitions. In addition, locations of fool-proof notches on the golden fingers are different, so both are not compatible.

Though the DDR3 module is developed based on the DDR2 and also uses the 240-pin design, both the pin layout and signal definition of the DDR3 module are different. The difference is also seen in the fool-proof cut on the gold finger. Therefore, they are not compatible. Moreover, the DDR3 has enhanced I/O buffer performance by means of the 8-bit prefetch technology. Therefore, it can break through the clock speed limit of the DDR2 module. As a result, the data rate of the DDR3 module begins from 800MHz, and it will increase to DDR3-1066, DDR3-1333, and DDR3-1600 in the future.

Refer to the user manual of the motherboard. The additional setting is unnecessary because BIOS on the motherboard would detect SPD parameters on Memory Modules automatically after the memory has been installed.
