Kingston KHX12800D3LLK3/6GX (HyperX)
Kingston is one of the most well-known memory makers for enthusiasts. The company has earned their reputation due to the fact that they have been among the overclocking memory leaders for many years. That is why we are not surprised to see the broadest range of solutions this company has to offer for Core i7 processors with frequencies reaching the impressive 2133 MHz. However, the company also doesn’t forget about the mainstream DDR3 frequency range, where 1600 MHz memory actually belongs. For example, we received HyperX KHX12800D3LLK3/6GX kit for our roundup. This triple-channel 6 GB DDR3-1600 kit is designed to work with 8-8-8-24 timings and 1.65 V voltage.
These pretty popular specifications go side by side with a quite common cooling system. Aluminum heat-spreaders of Kingston’s own recognizable design but of standard size cover both sides of the memory modules. Due to the fact that Kingston decided not to experiment with the heat-spreader shapes, this memory will easily fit into any system.
Another advantage of Kingston memory modules is their broad compatibility. Since Kingston Company is one of the industry leaders, most mainboard manufacturers use Kingston memory to test their new products. As a result, you are very unlikely to ever come across non-operational configurations involving Kingston memory modules.
Therefore, no wonder that the SPD of HyperX KHX12800D3LLK3/6GX is filled out extremely accurately and thoroughly. There are three settings profiles available for compatibility and one for XMP with nominal timings for 1600 MHz operational frequency.
Mushkin 998679 (XP Series)
Mushkin Company was among the first ones to send us their DDR3-1600 memory kits that support CAS Latency = 7. Note that the manufacturer didn’t increase the voltage over the Intel recommended 1.65 V in order to achieve this latency. As a result, they ended up with a 6 GB 998679 memory kit with very attractive parameters supporting 7-8-7-20 timings and 1.65 V voltage.
I have to say that despite more advanced nominal parameters than by most other memory kits, the price of Mushkin 998679 wasn’t affected and this kit becomes a very attractive purchase. Another advantage these modules can boast is their low-profile aluminum heat-spreaders that do not cause any problems during modules installation into DIMM slots.
Unfortunately, Mushkin engineers decided not to support XMP technology, so the user is fully responsible for configuring the memory subsystem. Moreover, we can’t help mentioning the fact that during our test session we came across some problems. Platforms built around Gigabyte mainboards for some reason refused to work stably with Mushkin 998679 with the nominal settings, that is why we could only test this memory with 8-7-7-20 timings in the beginning. Luckily, this issue was completely fixed in the new BIOS versions and today this memory can work perfectly fine with even better timings.
