Kingston HyperX Predator 2666MHz 8GB Kit

Posted by on Wednesday, October 31, 2012 - 8:00am

Over the past few months we have had the pleasure of reviewing some very fast memory. We have seen some 1866MHz kits from the likes of Corsair, Crucial, G.Skill and Kingston. And the fastest up to this day has been a kit from G.Skill which was dialed in at 2400MHz by default. But today we are topping that with a new 2666MHz kit from Kingston. The HyperX Predator at 2666MHz boast timings f 11-13-13-32 and some pretty awesome heat spreaders.

Introduction

Over the past few months we have had the pleasure of reviewing some very fast memory. We have seen some 1866MHz kits from the likes of Corsair, Crucial, G.Skill and Kingston. And the fastest up to this day has been a kit from G.Skill which was dialed in at 2400MHz by default. But today we are topping that with a new 2666MHz kit from Kingston. The HyperX Predator at 2666MHz boast timings at 11-13-13-26 and some pretty awesome heat spreaders.

Kingston’s take on the HyperX Predator

Kingston's KHX26C11T2K2/8X is a kit of two 512M x 64-bit (4GB) DDR3-2666 CL11 SDRAM (Synchronous DRAM), 2Rx8 memory modules, based on sixteen 256M x 8-bit FBGA components per module. Each module kit supports Intel® XMP (Extreme Memory Profiles). Total kit capacity is 8GB. Each module kit has been tested to run at DDR3-2666 at a low latency timing of 11-13-13 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

The new HyperX Predator is basically the continuation of the Hyper T1 series, and now serves as Kingston’s highest end memory. Just like the T1, the HyperX Predator goes through quite a bit of testing to make sure they run at the advertised speeds and timings.

The HyperX Predator series comes in frequencies ranging from 1600 to 2666 megahertz, and kit capacities of 8GB, 16GB and 32GB; today's 2666MHz kit only comes in an 8GB. The voltage range is between 1.5 and 1.65 volts depending on the kit. If for some reason you did pick up this 2666MHz there is a second XMP profile to run them at 2400MHz.

While the new Predator series are dressed differently than their forerunner T1 line, the two series do share some visual similarities. Designed with tall (2 ½”) blue aluminum heat spreaders, these may cause some issues with CPU air-cooling. Considering who these sticks are designed for the height of the spreaders may not be an issue. People with water-cooling systems or those going the extreme-cooling route will see the height as a non-issue.

The only distinguishing aspect of the memory modules is the large black 'X' that spans nearly the full height where it meets the cut-in. Even though the heat spreaders are tall, they are far from flashy.

Overclocking

When it comes to many Ivy Bridge processors, getting one that can handle the IMC running at 2666MHz can be a challenge. There is also matter of finding a motherboard that can run memory at such a speed, but that is easier than finding the CPU that can do it. We know we have both of the mentioned products to achieve some better-than-average numbers when it comes to the IMC.

To start our adventure we left the default timing and voltage alone and selected 2800MHz in the Memory Timing option in the BIOS. No go. We upped the voltage to 1.75 which we normally do not do, but what the hay. Still no go. Could it be the motherboard or the CPU? No idea.

Next, we decided to see what would happen if we left the default settings intact and up the BCLK. We were able to boot at 101 but stability wasn’t there. At this small jump and still no success, we halted our testing.


Results

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.”


FuturemarkPCMark 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.”


Conclusion

This Kingston HyperX Predator 8GB kit, sporting a 2666MHz frequency, is great for those that want to push their system even more without having to go through all the tweaking that is needed to achieve a frequency this high. Imagine not having to go through the hours, or even days of adjusting voltages, base frequencies and the numerous timings. Just let the manufacturers handle it for you!

The visual aspect of the kit I think is pretty good. There is no flash or bling to deal with. The blue coloring is easy to coordinate with the rest of your other components. We feel it would look ideal in Gigabyte’s blue PCB motherboards, or in an ASUS blue-on-black motherboard.

If you are not fortunate enough to have a motherboard or CPU that can run at the rated 2666MHz there is an optional XMP profile to allow the ram to run at a lower 2400MHz frequency as well.

Granted, we have no issues with the cosmetics of the Predator series, but we do see people having issues with the height of the heat spreaders. At 2 ½” tall, you will not be able to fit them under too many high-end air-coolers on the market.

This kit is not cheap either, as it will cost you about $175 online. For example, at Newegg we found three kits with the same specifications and the Kingston model was the most expensive by, ten and twenty dollars. So, guess it boils down to personal preference on which to buy.
