Part Number Decoder

HyperX memory is designed specifically for PC enthusiasts and gamers. The following information is designed to help you identify Kingston HyperX memory modules by specification.

Glossary

Capacity: Total number of memory cells on a module expressed in Megabytes or Gigabytes. For kits, listed capacity is the combined 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. Once the data read or write command and the row/column addresses are loaded, CAS Latency represents the (final) wait time until the data is ready to be read or written.
DDR3: Third generation of Double Data Rate (DDR) SDRAM memory. Similar to DDR2, it is a continuing evolution of DDR memory technology that delivers higher speeds (up to 1600 MHz), lower power consumption and heat dissipation. It is an ideal memory solution for bandwidth hungry systems equipped with dual and quad core processors and the lower power consumption is a perfect match for both server and mobile platforms
DDR2: Second-generation DDR memory technology. DDR2 memory modules are not backward-compatible with DDR due to lower voltage, different pin configurations and incompatible memory chip technology.
Kit: A single package containing multiple memory modules: K2 = 2 modules in a kit.
Registered: A memory module containing Register chip(s) used to relay and synchronize address and control signals issued by the motherboard's memory controller, and a Phase Locked Loop (PLL) chip used to relay the motherboard's clock signal to all the DRAM chips.
Speed: The data rate or effective clock speed that a memory module supports.

† The information below will help illustrate the appropriate settings when adjusting the memory timings in the motherboard BIOS for optimum performance. Please note that these settings may vary depending on motherboard make/model or BIOS update.

Sample:

Part Number	Timings
KHX3200A/512	2-3-2-6-1

Timing	Definition	Abbreviations	What it does
2	CAS Latency	CL	Delay between activation of row and reading of row
3	RAS to CAS (or Row to Column Delay)	tRCD	Activates row
2	Row Precharge Delay (or RAS Precharge Delay)	tRP/tRCP	Deactivates row
6	Row Active Delay (or RAS Active Delay, or time to ready)	tRA/tRD/tRAS	Number of clock cycles between activation and deactivation of row
1	Command Rate	CMD Rate	Delay between chip select and command

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