Testing:

To find out just how well a product performs, you have to test it in a real world environment so that you don't just blindly believe what the manufacturer says the product will do. Some are right on the money, while others fall somewhat short. On the other hand, there are products that exceed the manufacturer's specifications and will perform at a higher level than what the specifications lead you to believe. To find out what kind of performance the Kingston modules deliver, I will be running them through the OverclockersClub suite of benchmarks to see how the performance compares to that of modules that are rated both lower and higher than the rated speed and timings of 9-9-9-27. The CPU is run at the default clock speed of 133 x 20 and the memory multiplier is increased to reach the rated speed of each set of modules. For the overclocking test I will use a combination of increasing the bclock on the CPU to increase the clock speed of the Kingston HyperX modules.

Testing Setup:

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.

 

Overclocking:

Overclocked settings:

  • Processor: Intel Core i7 920 162x20 = 3240MHz
  • Memory: Kingston PC3 12800 9-9-8-24 1976MHz

Since the modules are rated at 1600MHz 9-9-9-27 what better place to start then to see if the loose timings can be improved upon. To start with I lowered the Cas Latency, TRTP and TRD to 8 and the TRAS to 24 all while running the default 1.65 volts. Expecting a black screen I was surprised that the modules booted and then tested fine at 8-8-8-24. Next I started bumping the memory speed up by increasing the bclock a few MHz at a time and rebooting. Then thing is the modules kept scaling with the 8-8-8 subtimings until I reached 1884MHz. So far 284MHz worth of extra clock speed. At this level I was able to benchmark game and run stability tests at will. Any higher though required the Cas Latency to move to 9. Voltage did not help and above 1.68 I would get errors so the max voltage used was 1.67 volts. Moving on up from 1884 I finally reached 1976MHz with the timings at 9-9-8-24 with the memory voltage at 1.66 volts QPI volts at +220 and the CPU at 1.28 volts. 376MHz (187MHz actual) worth of increase for a set of memory that costs just 131 bucks is nothing to sneeze at. Unfortunately 2000MHz just was not to be for me on this set. So close yet so far.
