Review: Kingston 2400Mhz 2x4GB/8GB kit (KHX24C11T2K2/8X)

kingston 2400 ram feature

It’s time for a quick review and in an effort to build up some decent RAM reviews for the future, Kingston have been kind enough to send us out a few of their RAM kits to put to test and gauge the performance they offer. The kit up for review here is the Kingston 2400Mhz with 2 x 4GB sticks totaling 8GB, model number KHX24C11T2K2/8X. The full specs are included below and then we move onto some benchmarks.

It’s time for the numbers! We put together a few benchmarks using the kits that Kingston sent out to us and this should give you an idea of the performance the 2400Mhz kit provides and not just on its own, but compared to the 2133MHz and 1866Mhz kits we also reviewed.

The 2400Mhz kit from Kingston has solid performance with the memory bandwidth giving you the top of speed you would expect, but more impressively the latency is much lower compared to the other kits, which will greatly increase performance throughout the entire RAM. So basically if your looking for top-notch performance you will be hard pressed to find anything better from a different 2400Mhz kit. Currently this kit costs around £100-110 which is around the same or less than most of the competition.

We are pleased to give the KHX24C11T2K2/8X kit from Kingston a gold award as its performance is spot on and Kingston have shown nothing but consistency throughout performance and it’s hard to ask for more.
