Clock speed
The amount of information that a memory module can receive or transmit in one second. The speed of the memory and, accordingly, the price of it directly depend on the bandwidth. At the same time, this is a rather specific parameter, which is relevant mainly for high-performance systems — gaming and workstations, servers, etc. If the RAM module is bought for a regular home or office system, you can not pay much attention to bandwidth.
Lighting
Decorative href="/list/188/pr-29071/">lighting,, usually using LEDs. It does not affect the functionality of the memory module, but it gives it a bright and unusual appearance, which is appreciated by fans of external computer tuning. Of course, in order for this backlighting to be visible, the case must have at least a viewing window, and ideally a completely transparent wall.
It may include synchronization technology. Synchronization itself allows you to “coordinate” the memory backlight with the backlight of other system components — the motherboard, processor, video card, case, keyboard, mouse, etc. Thanks to this coordination, all components can synchronously change color, turn on/off simultaneously, etc. The specific features of such backlighting depend on the synchronization technology used, and each manufacturer usually has its own (Aura Sync for Asus, RGB Fusion for Gigabyte, etc.). The compatibility of components also depends on this: they must all support the same technology. So the easiest way to achieve backlight compatibility is to assemble components from one manufacturer. However, there are many memory modules in the multi compatibility format — that is, capable of working with several backlighting technologies at once. As a rule, such memory is produced by manufacturers that do not have their own backlighting technologies; a specific list of compatible technologies should be clarified separately.
