Comparative tests:
To highlight the gains obtained with different memory kit frequencies and timings, we’re going to use two benchmarks: AIDA64 and Geekbench 3. These are the two programs we use for our memory kit tests. We’ll run our tests at a frequency of 4800 MT/s CL40, which corresponds to the worst thing that can happen to you, i.e. a memory profile not enabled in the BIOS. Then, at the DOCP frequency of 6000 MT/s CL30 for our G.SKill kit, at the DOCP frequency of 7200 MT/s CL34 for our Teamgroup kit and finally at the overclocked frequency of 8000 MT/s CL34. As a reminder, before AMD introduced its new BIOS, the maximum stable frequency was 6400 MT/s.
Benchmark memory AIDA64 :
This software can provide you with a wealth of information about your configuration, but above all, it features a memory benchmark. This calculates the read, write and copy speeds, as well as the latency, of your memory kit. It is often used to compare memory kits. It’s an excellent tool if you want to compare the performance of your memory kit with those we’ve already had the opportunity to test. We used the latest beta version.
It’s true that it’s easier to get an overview by presenting the results in table form, but we wanted to show you the screenshots anyway.
The table speaks for itself, and performance is clearly improving. It’s already very important to note the impact of the DOCP setting. Here too, support for kits above 6400 MT/s brings a significant gain.
Geekbench 3.4.4 benchmark:
This benchmark is available in several revisions, version 6 having just been released a few weeks ago. It provides two scores: one single and one multi. Using this benchmark, we’re going to focus on the performance obtained on the ” Memory Multi-Core ” score, which also differentiates memory performance.
And the results in tabular form so that you can see the gains once again. As in AIDA64, we can also see the significant performance gain between a 6000 MT/s and a 7200 MT/s kit. We are now preparing a comparison of the gains obtained in gaming mode, so please wait a little longer.
Activating the DOCP profile once again shows its importance. Be aware that some online PC vendors forget to activate the profile within the BIOS. Use the CPU-Z software to check that this is active, and if not, head for your BIOS.
Go a step further:
If you’re in the mood for higher scores, you can also increase the FCLK frequency. This is also modified within the BIOS, but can alter the stability of your configuration. Here, we’ve increased the FCLK to 2133 MHz instead of 2000 MHz with our 8000 MT/s CL34 kit.
To conclude this short article, congratulations to AMD on their work, which enables them to support memory kits with high frequencies, as is the case with Intel. And finally, don’t forget to activate your XMP/DOCP profile in your BIOS!
