Review: Kingston 1866Mhz 4x4GB/16GB kit (KHX18C9X3K4/16X)

Kingston 1800c9 (2)

In an effort to build up our RAM review collection, a big thanks to Kingston, who have been kind enough to send us out a few of their RAM kits to review. The kit up for review here is the Kingston HyperX 10th Anniversary Series 1866Mhz with 4 x 4GB sticks totaling 16GB, model number KHX18C9X3K4/16X. The full specs are included below and then we move onto some benchmarks.

We put together some benchmarks with some of the top benchmark programs available that really put the RAM through some decent tests. currently we only have 2 other RAM kits from Kingston to include with the charts, but they should give you a good idea of the performance not only this RAM provides, but also in comparisons to higher spec’d RAM.

Pretty much everyone in the computer industry has heard of Kingston and of course their RAM products. All the different benchmarks show one thing and that’s consistency throughout. While 1866Mhz  kit isn’t the fastest RAM available, it still offers solid performance for those looking for more RAM over speed. The current price for the 16GB kit is just over €150 and we can see that that is the going rate with all RAM of this spec including the timings. So it really comes down to consumer choice on which RAM to go for. The Kingston is low-profile ram which means it won’t get in the way of any heatsinks, which can be a benefit over other RAM with tall heatsinsk themselves.

We definitely recommend the Kingston KHX18C9X3K4/16X as its tick all the boxes with performance, price and of course the included lifetime warranty we are now use too with RAM these days. The low-profile design makes it a great choice for those with giant heatsinks, but the RAM is a good choice either way.
