Overclocking



Overclocking is the adjusting of the standard specifications on memory modules, CPUs, and GPUs, to eke out better performance. For example, raising the clock speed and lowering latency (wait states) of industry standard values (JEDEC) on RAM can significantly impact PC applications. HyperX memory modules feature two simple approaches to overclocking memory, Plug N Play for novices and Extreme Memory Profiles for experts.

For PC enthusiasts (formerly known as hobbyists), overclocking is an art form and its own subculture. The most intense overclockers will go to extreme lengths like cooling their components in liquid nitrogen to compete for world records. However, not everyone who wants a powerful gaming rig needs to be an artist to extract better performance from their hardware. In the mid-2000s Intel, AMD, and NVidia devised methods that would allow for simple overclocking of memory through profiles programmed onto the DIMM. These profiles defined clock speed, voltage, and latencies. An ecosystem of checks and balances developed between the chipset/processor makers, the motherboard manufacturers, and the memory companies and this provided a stable landscape. As a result, it’s never been easier for enthusiasts and non-enthusiasts alike to push the performance of their memory modules.

Plug N Play



HyperX Plug N Play is a memory overclocking concept pioneered by Kingston. Featured on the FURY and Impact memory product lines, HyperX Plug N Play is auto-overclocked memory, with presets that are configured by our engineers at the factory. There’s no need to change settings and timings manually, nor select a profile. Since the profiles work at standard voltage, you can simply plug them in, and they’re ready to go. Plug N Play is ideal if you have a system that doesn't allow for memory adjustments in the BIOS, or simply if you want an easy solution to get better performance from your memory. In most systems, HyperX Plug N Play will auto-overclock itself up to the maximum speed allowed by the BIOS.

Intel XMP


Intel



Intel’s approach to memory overclocking is called XMP (Extreme Memory Profile). XMP are preset overclock settings programmed into the DIMMs at the factory. Each DIMM comes with two overclocking profiles, one aggressive, one slightly less aggressive, as well as the default JEDEC values (industry standard speed, timings, and voltage). This is Intel’s solution to safe, guaranteed memory overclocking on Intel platforms. XMP profiles can be enabled within the BIOS, or through Intel’s Extreme Tuning Utility (XTU), which is available for download on their website.

There are two classifications of Intel XMP: Certified and Ready. Intel XMP Certified means the DIMMs have been verified to work by Intel on specific model motherboards. These results are compiled and posted on Intel’s XMP website. Intel XMP Ready means the DIMMs come with XMP profiles and have been tested at the memory manufacturer at the advertised speeds; however, they have not been submitted to Intel.
