Kingston HyperX KHX1600C9D3K2/4G Memory Review

» Discuss this article (14)


Memory can often be an overlooked part of a computer, with many users buying the more cost effective memory instead of the most effective memory. For the average consumer, this usually works, but for the enthusiast market, being held back due to memory can be a major hindrance in achieving optimal system performance. This sadly is the case with many promising sets of memory on the market today. So far, I have been impressed with the build quality and design of The HyperX KHX1600C9D3K2/4G kit of memory, but now we get to put them through some stress testing and see how well they hold up against the competition. I will be using a series of benchmarking programs to test the performance of the memory both at stock and overclocked speeds. In the comparison, I will be matching the HyperX kit against a set of Corsair XMS3 and OCZ Spec Ops memory.

Testing Setup:

  • CPU: AMD Phenom II X4 955
  • Motherboard: Gigabyte MA790XT-UD4H
  • Memory: Kingston HyperX 2x2GB DDR3 1600 CAS 9
  • Video Card: Nvidia GTX 260-216
  • Power Supply: Zalman 750 watt Modular Power Supply
  • Hard Drive: Seagate 750GB 7200.12 SATA
  • Optical Drive: ASUS SATA DVD-R
  • OS: Windows Vista Ultimate 64-bit SP1


Comparison Modules:

  • Comparison Module #1: Corsair XMS3 DHX 2x2GB DDR3 1600MHz 9-9-9-24
  • Comparison Module #2: OCZ Spec Ops Urban Elite DDR3 2x2GB 1600MHz 8-8-8-24





CPU-Z: This application shows us the settings that we have chosen in the BIOS. Items shown in this application include CPU speed and bus settings, motherboard manufacturer, BIOS revisions, memory timings, and SPD chip information.


Task Manager: We use this utility to show physical memory, kernel memory, page file, and processor usage.



Overclocked settings:

  • Processor: AMD Phenom II X4 955 @ 218x15.5 = 3379MHz
  • Memory: Kingston HyperX @ 9-9-9-29 DDR3 1744MHz 2.0v

When it came to overclocking this set of memory, I was able to achieve a stable overclock of 1744MHz. I was able to reach the max clock speed with only a small adjustment to the timings, and by raising the voltage to 2.0v. I was able to get the memory to boot into Windows at higher rated frequencies than 1744MHz, but it was not stable and would crash almost instantly after a benchmark was started. After the system crashed, I tried raising the voltage, lowering the timings, and adjusting the Northbridge frequencies, but they simply could not manage anything over 1744MHz and remain stable. Just for fun, I tried to reach the 1800MHz mark, but once there, my system could not boot at all. Even though they could not reach 1800MHz, they still performed well with the 144MHz overclock. The kit of memory I received required 1.9v to run stable at 9-9-9-27. This does fall into the voltage specifications listed by Kingston, but the fact that they can not run at lower voltages could hold their overclocking potential back, as they require a lot of power just to run stock timings.


The benchmarks used in this review include the following:


  • CPU-Z Version 1.49
  • Windows Task Manager
  • PCMark Vantage
  • SISoft Sandra 2009
  • Left 4 Dead
