Glossary

Capacity

The total number of memory cells on a module, expressed in gigabytes. For kits, the listed capacity is the total capacity of all modules in the kit.

CAS Latency

One of the most important latency (wait) delays (expressed in clock cycles) when data is accessed on a memory module. CAS latency represents the final wait time until the data is ready to be read or written after the command to read or write data has been sent.

DDR4

The generation of Double Data Rate (DDR) SDRAM memory. Similar to DDR3, it is a continuing evolution of DDR memory technology that delivers higher speeds, lower power consumption and improved heat dissipation. It is an ideal memory solution for bandwidth-hungry systems equipped with dual and quad core processors. The lower power consumption is a perfect match for both server and mobile platforms.

Kit

A single package containing multiple memory modules: K2 = 2 modules in a kit.

Frequency

The data rate or effective clock speed that a memory module supports.

DIMM Type

UDIMM (Unregistered Dual In-line Memory Module). This is a type of memory used mostly in desktop and laptop computers. More commonly referred to as unbuffered memory.

SODIMM (Small Outline Dual In-Line Memory Modules) is a type of memory built using integrated circuits. SODIMMs are smaller alternatives and can be used in compact systems.

Latency timing

The information below helps to illustrate the various settings that can be adjusted when setting the memory timings in the motherboard BIOS for optimum performance. Please note that these settings may vary depending on motherboard make/model or BIOS firmware version.

Sample timing

15
CL

17
tRCD
-
17
tRP/tRCP
-
20
tRA/tRD/tRAS

CAS latency (CL): Delay between activation of a row and the reading of that row.

RAS to CAS or RAS to column delay (tRCD): Activates the row

Row precharge delay or RAS precharge delay (tRP/tRCP): Deactivates the row

Row active delay or RAS active delay (or time to ready): Number of clock cycles between activation/deactivation of row.

Note: All HyperX products are tested to meet our published specifications. Some systems or motherboard configurations may not operate at the published HyperX memory speeds and timing settings. HyperX does not recommend that any user attempt to run their computers faster than at the published speed. Overclocking or modifying your system timing may result in damage to computer components.
