Testing and Results

Testing Methodology

As mentioned before, I’ll be doing a head-to-head comparison between the Crucial Ballistix Elite DDR4-2666MHz, and the Corsair Vengeance LPX 2400MHz Memory kit. I used their XMP profiles to set their timings, which my motherboard had no issues setting and were perfectly stable.

For comparison sake, I’ll list the timings of each RAM kit:

Crucial Ballistix Elite: 16-17-17-36 CR-1 2666MHz

Corsair Vengeance LPX: 14-16-16-31 CR-2 2400MHz

Test System

  • Motherboard: GIGABYTE GA-Z170X-Gaming 6 (rev. 1.0)

Test Software

  • Aida 64 Engineer 5.75.3900
  • SiSoft Sandra Lite 2016.03.22.20
  • Passmark Performance Test 9.0
  • CPU-z 1.76.0
  • Handbrake 64 bit
  • 3D Mark 11 Profesional Edition
  • Heaven Benchmark 4.0
  • Valley Benchmark 1.0


AIDA 64 Engineer 5.75 Memory Test

Aida 64 is one of the main staples of synthetic tests for finding maximum theoretic memory bandwidth. As with all synthetic benchmarks, this isn’t an accurate means to measure real-world performance. But, for the purposes of comparison in this article it will suffice.


The higher bandwidth Crucial Ballistix Elite wins out in all 3 categories. Crucial Ballistix Elite manages an 11.82% increase in read, 10.71% in write, and 9.51% in copy. Synthetic maximum bandwidth should be taken with a grain of salt, as it usually bears little real-world results.

SiSoft Sandra Lite 2016.03.22.20

SiSoft SANDRA (System Analyzer, Diagnostic and Reporting Assistant) compromises a whole suite of benchmarking tools to analyze the performance of various hardware components. That is outside the scope of this article and we’ll be focusing on the memory tests specifically.


Again we see the Crucial Ballistix Elite pull ahead by a margin of 9.46% in Integer, and 10.28% in Float. That is a consistent margin between the first two tests.

Passmark Performance Test v9.0

Passmark has a variety of test suites, not unlike Aida 64 and SiSoft Sandra. We are only interested in the memory performance, comparing uncached read, cached read, and write tests.


Passmark shows a bit of a different story between the two kits of RAM. With only 5.11% difference between uncached read, 0.47% in cached read, and 6.33% in write performance, Crucial can only claim a slight victory in the uncached read and write categories, while the cached read is a wash.

CPU-z 1.76.0

CPU-z is a widely known application for retrieving mainly CPU specs, cache, and motherboard information. We are interested in the benchmark for single and muti-threaded performance for this article.


The reference Intel 6700K scores 2064 in single threaded, and 8767 in multi-threaded performance. Comparing these numbers it’s pretty much a wash. The biggest difference here is -0.75% in multi-threaded performance to the Corsair Vengeance kit. This was consistent when tested multiple times. I’m guessing the lower CAS timings play a bigger part in the multi-threaded performance for this test, as memory speed seems to make no difference between these two memory kits.

Testing and results continued on the next page.
