Kingston HyperX blu KHX1600C9D3B1K2/4GX Review



Testing of the Kingston HyperX blu modules was done a little differently, because of the "entry level" sector that these modules fall into. I will try the optimized XMP profile to make sure it works as promised, then run the memory at the JEDEC standard frequency of 1333 MHz to make sure the memory can run at the stated frequency, timings and voltage specified by Kingston. Then, I will see how it runs at the rated frequency of 1600 MHz at 9-9-9-27 @ 1.65v, and then try to tighten up the timings at the stock rated speed. Finally I'll try to push the memory to see if there is any overhead for the overclockers out there.


Testing Setup:

  • CPU: Intel core i7 860
  • Motherboard: Gigabyte P55UD4P
  • Memory: Kingston HyperX blu DDR3 1600 CAS 9 4GB Kit
  • Video Card: Gigabyte HD 5870
  • Power Supply: Enermax Modu-82+ 625W
  • HDD: Patriot Torqx 128 GB, Seagate 640 GB 7200.11
  • Optical Drive: Samsung DVD-R
  • OS: Windows 7 Home Premium 64-bit

Comparison Modules:


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: Intel core i7 860 at 174 X 18
  • Memory: Kingston HyperX blu at 2088 MHz 9-11-9-28


The overclocking was a very pleasant surprise from a set of memory stated by Kingston to be entry-level and not performance. The JEDEC standard frequency of 1333 MHz at 1.5v even allowed some surprises, as it allowed the timings to be tightened to 6-7-6-20. Stock 1600 MHz speed allowed me to tighten the timings to 7-8-7-27. This got me rather optimistic to try and see how high they would go. There turned out to be a lot of headroom with this memory to the point that I had it over 2200 MHz at one time, but it did require looser timings than would be practical. Taking the time to balance the higher frequency capability with tightening of the timings could really pay off with this RAM. I settled on a rather nice 2088 MHz speed and slightly looser timings of 9-11-9-28 for the comparison benches.

The XMP profile worked just as it should by bringing the memory up to the 1600 MHz rated frequency and timings.


The maximum memory speed for each set of modules when overclocked is a measure of how well the modules ran on these particular modules and test system. As such, your results may differ in either a positive or negative way based on the capabilities of your hardware. That said, your mileage may vary!
