Kingston HyperX Genesis DDR3 1866 16GB Quad Kit

Kingston HyperX DDR3 1866MHz 16GB KitToday, we will be taking a good long look at some memory from their HyperX line. The ram official title is KHX1866C9D3K4/16GX but many will know it better by HyperX Genesis. We were handed 16GB of DDR3 1866 in four sticks. This kit is geared towards the motherboards featuring the Intel X79 chipset but can be used in many others.

Introduction to the Kingston HyperX Genesis DDR3 1866 16GB Quad Kit

With the way memory prices are today there really isn’t no reason you should not have the right amount of ram to do all the computing you need. Some people consider themselves just regular or average PC users and for those folks 8GB is usually enough. But for those that consider themselves power users will opt for greater amount of ram, somewhere in the neighborhood of 16 gigs. But of which are mostly affordable.

Kingston is one of those companies that make memory that is compatible with every PC it seems. I, personally have never ran into a time where some Kingston ram didn’t fit right with a rig. I guess that is why they are one of the largest memory manufacturers around.

Today, we will be taking a good long look at some memory from their HyperX line. The ram official title is KHX1866C9D3K4/16GX but many will know it better by HyperX Genesis. We were handed 16GB of DDR3 1866 in four sticks. This kit is geared towards the motherboards featuring the Intel X79 chipset but can be used in many others.

Kingston’s take on the HyperX

Kingston’s KHX1866C9D3K4/16GX is a kit of four 512M x 64-bit (4GB) DDR3-1866 CL9 SDRAM (Synchronous DRAM) 2Rx8memory modules, based on sixteen 256M x 8-bit DDR3 FBGA components per module. Each module kit supports Intel® XMP (Extreme Memory Profiles). Total kit capacity is 16GB. Each module kit has been tested to run at DDR3-1866 at a low latency timing of 9-11-9 at 1.65V. The SPDs are programmed to JEDEC standard latency DDR3-1333 timing of 9-9-9 at 1.5V. Each 240-pin DIMM uses gold contact fingers.

Closer look

To get this party started right we must first tell you the HyperX line consist of many different size modules ranging from 1 GB to 8GB. Kits sizes re from 2GB to 32GB. But the most impressive numbers would be the bus speed which starts at 1333 MHz and ends at 2133MHz. These numbers along will suggest that Kingston has everyone covered that is in need of DDR3 modules.

The kit we will be taking a look at are a quad set of 1866 MHz modules totaling 16GB. At this amount most people would be totally satisfied with their computing power and level of resources. The timings of the kit are also incredible as they are 9-11-9 at 1.65v. But there is a secondary XMP 1600 MHz which is set at 9-9-9 at the same voltage.

Many may know that the above numbers are above that of the IMC of the Intel Sandy Bridge-E processors which 1600MHz. but many motherboard manufacturers have made it where their boards will support memory in excessive that of the IMC of the CPU. For instance our test mainboard, ASUS X79 Deluxe with the latest 1103 BOIS will support up to 2666 MHz.

This is done with overclocking the processor like we have seen in previous chipsets. The link between the CPU ratio and the memory bus is no longer a factor while using whatever predetermined speeds of the BIOS. This does change when you begin playing with the Straps.

The Genesis line of HyperX memory all consist of blue heat spreaders not to be confused with the gray heat spreaders of the PnP and the Green ones on the LoVo. The heat shields are tastefully done with silver accents. This maintains a minimum height clearance making them a non-issue with aftermarket CPU heat sinks.

The only real sign of finesse on these modules are the HyperX logo and the large X logo. The holes that align the upper half of the modules are to help with heat dissipation. There is a small product sticker to identify the modules.

Were we have some screenshots of how our test motherboard read the XMP profile(s) of the reviewed memory kits.


We had our hands full overclocking our first set of quad channel memory on the Intel X79 chipset. Overclocking the memory was far more time consuming than that of the processor. Here we learn how the proper usage of the CPU Strap which is a new multiplier allowing overclockers to achieve better clocks.

We begin our overclocking adventure with simply trying to get the memory to run at the default speeds within the BIOS. We initially tried 2133 MHz which was the next selection above the default 1866 MHz of the ram. At the same XMP timings of the 1866MHz settings we were not able to get the system to post. Then we begin to loosen the timings to set how tight we could get 2133 MHz to boot. Finally, we were able to get 2133 MHz to post but at 10-11-10 which is still good.

Next, was 2400 MHz which we were not able to get the system to boot at any timing. We figured it was time to get manual and see what the maximum speed we were going to get out this kit. Sorry to say that 2133MHz was the highest stable clock we could achieve.


AIDA64 Extreme Edition
“FinalWire Ltd. today announced the immediate availability of AIDA64 Extreme Edition 1.50 software, a streamlined diagnostic and benchmarking tool for home users; and the immediate availability of AIDA64 Business Edition 1.50 software, an essential network management solution for small and medium scale enterprises.
The new AIDA64 update implements AVX-optimized benchmarks for the upcoming Intel Sandy Bridge processors, adds a brand new video encoding benchmark, and supports the latest AMD and nVIDIA graphics processors.”

Super PI Modded 1.5
“In August 1995, the calculation of pi up to 4,294,960,000 decimal digits was succeeded by using a supercomputer at the University of Tokyo. The program was written by D.Takahashi in collaboration with Dr. Y.Kanada at the computer center. This record should be the current world record. (Details are shown in the windows help.) This record-breaking program was ported to personal computer environment such as Windows NT and Windows 95. In order to calculate 33.55 million digits, it takes within 3 days with a Pentium 90 MHz, 40 MB main memory and 340 MB available storage.”

Flying Wild Hogs Hard Reset
“Thee world as we know it ceased to exist. Humanity is at the verge of extinction, living in the last closed city of Bezoar. Mankind wages war against the machines controlling vast areas of what became the ‘Barrens’. Machines want to control and assimilate ‘The Sanctuary’ a network that holds billions of digitalized human minds. Our hero, Maj. Fletcher, is a soldier of CLN – a corporation combat unit, established to protect the city. Machines are constantly assaulting the walls of Bezoar. Fletcher moves in when Bezoar’s protective barrier is breached.”

Futuremark PCMark Vantage
“PCMark Vantage is a PC benchmark suite designed for Windows Vista offering one-click simplicity for casual users and detailed, professional grade testing for industry, press and enthusiasts.
A PCMark score is a measure of your computer’s performance across a variety of common tasks such as viewing and editing photos, video, music and other media, gaming, communications, productivity and security.
From desktops and laptops to workstations and gaming rigs, by comparing your PCMark Vantage score with other similar systems you can find the hardware and software bottlenecks that stop you getting more from your PC.”

MaxxMEM 2
“Is the *little brother of MaxxPI², it contains the same Memorybenchmark routine as MaxxPI² does.
So your reaced results will be comparable to Memory / Latency benchmarks done by MaxxPI².”

The HyperX series in general is ideal for those that want the memory to do it all for you and not having to go in the BIOS and start tinkering with different settings. With the a few clicks of the keyboard you can have memory running at 1600 MHz and if the motherboard allows 1866 MHz it does the rest on its own.

But for those that are willing and able 2133MHz is an easy goal with this particular kit we reviews. It ran this without a hiccup. And all under the 1.65v limit many say is the maximum on an Intel based system. Chances a little more could be had with more time and voltage but we feel we got more without having to spend more.

What I like and many will also is that you do not have to worry about CPU selection with this set of memory. We saw the kit clearly clear the fins of the rather large Thermaltake Frio Extreme and should not have issues with others. Definitely love to the idea of shorter heat sinks on memory.

The cheapest we saw this kit was at the Egg for around $130. It wasn’t the cheapest kit in the listing but it was one of the few with shorter heat spreaders.
