Kingston KHX1600C8D3K2/4GX (HyperX)
Kingston is one of the most well-known names in the enthusiast memory market. That is why we were not surprised to see that they offer just as many high-speed products for the LGA1156 platform, as they do for LGA1366. Their frequencies reach as high as 2133 MHz, which is impressive. However, the company doesn’t forget about the mainstream DDR3 SDRAM as well, and 1600 MHz kits are definitely among them. For our today’s tests we chose a 4 GB kit of two HyperX KHX1600C8D3K2/4GX modules that are selling at a very democratic price, which is very close to that of DDR3-1333 kits. Just like the Corsair modules we have just discussed, HyperX KHX1600C8D3K2/4GX DDR3-1600 memory supports 8-8-8-24 timings and 1.65 V voltage.
These pretty popular specifications come with a traditional cooling system. These modules are equipped with heat-spreaders of Kingston’s brand name design but pretty standard size. They cover both sides of the modules. Since Kingston decided not to experiment with large heat-spreaders, these modules will fit into any system featuring a large CPU cooler.
SPD of Kingston’s memory modules is pretty similar to that of Corsair’s. The standard settings profile is supposed to provide maximum compatibility at low frequencies. The XMP profile that makes it a lot easier to configure the memory sub-system in the mainboard BIOS Setup contains all the default settings.
Although HyperX KHX1600C8D3K2/4GX memory is intended to work with CAS Latency 8, we managed to achieve stability at much lower settings. This DDR3-1600 SDRAM kit successfully passed stability tests in Memtest 2.11 and Prime95 25.7 x64 with 7-7-6-20 timings.
I have to say that it is a pretty remarkable result. It turns out that HyperX KHX1600C8D3K2/4GX with default CAS Latency 8 can compete successfully against memory kits with CAS Latency 7, which are somewhat more expensive.
As for the overclocking potential of Kingston HyperX KHX1600C8D3K2/4GX with different timings, the table below lists all confirmed frequencies, when the tested memory remained stable:
This is where Kingston memory really surprised us: with 9-9-9-27 timings it went way beyond the psychological DDR3-2000 barrier and worked at an impressive frequency of 2172 MHz, which is truly unbelievable for DDR3-1600 SDRAM.
With other timings configurations HyperX KHX1600C8D3K2/4GX managed to go far beyond its nominal settings. These impressive overclocking results give us every right to recommend this memory kit to all overclockers: priced fairly low, it offers unimaginable potential for frequency increase as well as lowering the timings. We are proud to give Kingston HyperX KHX1600C8D3K2/4GX kit our Recommended Buy title:
Overall, I can conclude that the quality of memory chips used for overclocker memory modules has improved significantly lately. A few months ago we tested triple-channel DDR3-1600 SDRAM kits and at that time we didn’t see anything as impressive as today.
