Kingston HyperX Genesis KHX1866C9D3K2/8GX

The KHX1866C9D3K2/8GX kit is one of the fastest in the Genesis series. It is rated for 1866 MHz. Faster DDR3 SDRAM from Kingston is only available under the HyperX T1 brand.

The KHX1866C9D3K2/8GX modules resemble the above-discussed DDR3-1600 KHX1600C9D3K2/8G kit. It too included two 4GB modules shipped in the same plastic packaging and featured the same Genesis heatsinks. The difference can only be found by comparing their labels, which might be expected considering their specs.

Here are the specs of the Kingston HyperX Genesis KHX1866C9D3K2/8GX kit:

  • Dual-channel kit consists of two memory modules, 4 GB each;
  • Nominal frequency: 1866 MHz;
  • Timings: 9-11-9-27;
  • Voltage: 1.65 V.

Compared to its junior cousin in the Genesis series, the KHX1866C9D3K2/8GX kit is rated for a 266MHz higher clock rate at the expense of slightly increased timings. This acceleration is going to cost the buyer about $10, which is the price difference between these two Genesis series products.

Although with the same PCBs, the different Genesis products differ in memory chips. The KHX1866C9D3K2/8GX kit employs chips from Hynix instead of Micron. Labeled H5TQ2G83BFR-H9C, these have been getting more and more popular among suppliers of overclocker-friendly DDR3 SDRAM and can now be found in completely diverse products. For example, G.Skill and GeIL manage to build DDR3-2400 modules out of such chips, so this offer from Kingston may turn out highly appealing for overclockers.

The 1866MHz Genesis kit supports XMP and even has not one but two profiles. The first one describes the specified configuration whereas the second one allows using the modules in an in-between mode: DDR3-1600 with timings of 9-9-9-27 and voltage of 1.65 volts. The dual XMP profile is a typical feature of many Kingston products. This manufacturer gives you flexibility of choice even when it comes to automatic memory subsystem configuring.

The KHX1866C9D3K2/8GX kit is factory-tested in a faster mode, DDR3-1866. The high quality and full compliance with the specs can also be testified by us as we've been using such modules for half a year in our CPU tests and have had no problems with them. Most importantly, the low heatsinks allow easily installing these modules into any system case, both full-size cases with a massive CPU cooler and compact mini-ITX enclosures.

Like the rest of the HyperX series, the KHX1866C9D3K2/8GX kit comes with a lifetime warranty.
