PC configurator - Computer RAM

Operating Memory According to Device

• PCs - Their standard operating memory is in a DIMM format. Differences are found in basic parameters, such as capacity, frequency and timing.
• Servers - also use a DIMM operating memory format. Instead of high speeds, they primarily aim for optimal stability and flawless data retention.
• Laptops - use a reduced SO-DIMM operating memory format.

Memory Modules Performance

• DIMM - Dual In-Line Memory Module (DIMM) is the basic memory module format and is primarily designed for personal computers, servers and workstations.
• SO-DIMM - If you need RAM on your laptop, SO-DIMM is the solution. These are smaller standard memory modules. The SO abbreviation means small outline.

Type of Memory

• Memory Type - The type of memory must be compatible with the motherboard and the processor hardware. Otherwise the modules with these components will not work. Each motherboard clearly states the compatible memory in its description. Memory standards are not always mutually compatible.
• Memory Frequency - Memory frequency is a parameter defining the speed. Memory speed is measured by the ability to read and write data. Faster memory is always better, but it is not always crucial for all applications.
• Voltage - Lower voltages result in lower memory module power consumption. The voltage level must support the motherboard. Modern DDR4 operating memory reaches significantly higher frequencies despite a lower voltage.
• DDRL - These memory modules support a reduced voltage level.

• Timing - Timing or latency is the interval that elapses between the command being sent by the controller and the moment when the data is available at the memory output. The unit of these values is the frequency cycle.

Configuring Operating Memory Chips

Configuration in terms of memory means how the memory chips organise and connect together. One rank, which is the name for a block of chips, communicates through a 64-bit data bus. If the module has more than one rank, each has one whole data bus. This means that more ranks are equal to higher speeds. However, when it comes to the dual-rank memory modules, the impact on performance is not critical and is mostly a difference of a few percentage points. Dual-rank and single-rank modules are usually found in ordinary personal computers. Quad-rank modules are mostly found in server operating memory domains.
