Crucial 4x4GB 2133MHz DDR4 RAM review

Test machine

For this presentation I will be using a
computer with the following configuration:


  • Motherboard: ASUS X99-A
  • CPU: Intel
  • CPU cooler: Cooler Master 212evo
  • RAM:
    Crucial 4x4GB 2133MHz DDR4
  • VGA: AMD
    6670 1GB
  • PSU:
    Seasonic M12II 750W
  • HDD1: Kingston
    (OS Drive)
  • OS: Windows

Test applications

To test the performance of the Crucial DDR4
RAM, I will be using the following test applications in this quick first look.


We all know and use WinRAR, as it’s one of
the best compression programs, but it also has a build in benchmark feature, so
I let it run for two minutes and here are the results for the Crucial 2133MHz
DDR4 RAM. For comparison I will be overclocking the RAM to 2400MHz.

In the above graph we can see the
difference between the non-overclocked RAM, there is a difference when it comes
to numbers but even at 2133MHz the Crucial RAM has very good performance for
value RAM.


is a lightweight tool that allows you to estimate the performance of your
computer’s memory with minimum effort. With MaxxMEM2 you can test your
RAM speed when writing, reading, or copying files. You can also view the memory
latency in order to estimate its effect on the computer performance. You can
get MaxxMEM2 from

This is the part where I should be
displaying the results, however MaxxMEM2 wasn’t able to recognise the hardware,
and it also gave some very strange results. The most notable thing was when the
memory was running at 2400MHz and it made the system very unstable. I did also
try the newer version but it still didn’t want to run correctly, so I will only
provide the one screenshot with the best result that I got after three runs.

AIDA 64 is great software. It can help you
identify your hardware, it can test your system for stability, and you can also
use it to do benchmarks. For this test I will be using the memory benchmarking
features of AIDA 64. Below are the results for memory read/write/copy and also

are the results at the stock speed and at 2400MHz, and you can see there is an
improvement when the RAM is overclocked.

As it was expected the memory latency is
higher from the DDR3 memory, but when the memory was running at 2400MHz with
the same timings as the 2133MHz test, I was able to obtain some improvement in the
latency, so it looks like there is something to be won, if you have the time to
play with the memory settings.

Cinebench 11.5

Cinebench is a real-world cross platform
test suite that evaluates your computer’s performance capabilities, and with
this test we can see if there is a difference in performance.

We can see a small benefit when the Crucial
RAM is working at 2400MHz but even at the default speed the Crucial RAM is giving
very good performance.


Crystal Disk Mark doesn’t need an
introduction, it’s a benchmark tool that I have used in all my reviews from SSDs
to USB flash drives, in this case it will be used to benchmark the virtual disk
that is created in the system memory. The size of the virtual disk is set to

Let me start by comparing the read results for
the stock and the overclocked DDR4 RAM and also the same for the write tests.

An impressive improvement when the RAM is
pushed to higher speeds, but even at the default 2133MHz the DDR4 memory is
capable of giving results that are out this world when it comes to speed.

Again the same scenario, when the RAM is
pushed to 2400MHz it gives excellent performance, but again even at 2133MHz the
DDR4 memory from Crucial is a very good choice when it comes to performance.

Let’s head to the next page and what happens
when you play with timings and the memory speed.
