Overclocking:
Good news when it comes to overclocking, as things will be totally different from what we experienced with the Ryzen 7 7800X3D. AMD has confirmed that the Ryzen 7 9800X3D will benefit from the same overclocking options as the other processors in the 9000X range. So we’ll be able to take advantage of the free multiplier to try and push our sample to the limit!
As a reminder, with the Ryzen 7 7800X3D, we could only modify the BCLK frequency, with fairly limited gains, and above all, a processor that became a veritable mini-oven. Let’s start by overclocking the processor before moving on to the memory.
Overclocking our Ryzen 7 9800X3D :
There is (no longer) any processor overclocking profile in the BIOS. We thought we’d seen one on previous BIOSes, but on the latest one, 0606, there’s nothing, apart from an LN2 profile.
So, straight to Windows 11 to use the AMD Ryzen Master software. If you’re a regular visitor to our site, you’ll be familiar with this software. It will allow us to modify the multiplication coefficient of each core independently. This is the strong point of this Ryzen 7 9800X3D compared with the previous generation. During our frequency tests, we noticed that when all 8 cores are used, the frequency is 5225 MHz. The idea is to exceed this frequency.
After a series of tests, we were able to reach 5500 MHz on the 8 cores with a voltage of 1.20 volts(Lvl 7 calibration). Our Cinebench R23 score went from 23449 to 24867 points, a gain of 5.8%.
Overclocking the 2 x 16 GB G.SKILL 8000 MT/s CL38 kit:
EXPO profiles :
There are several ways of optimising the performance of our memory kit. The first, of course, is not to forget to activate the EXPO profile in the BIOS, otherwise your kit will run at 4800 MT/s CL40. Our latest tests also showed that the Tweaked EXPO profile performed even better than the ‘simple’ EXPO profile.
You can see the differences in performance between these two profiles above. Let’s see how we can improve our performance even further.
BIOS memory profiles :
All ROG cards have a series of memory profiles in their BIOS. Some are interesting, others less so. With our kit already running at 8000 MT/s, we’re unlikely to get any better profiles. As we thought, the best profile in 2 x 16 GB is 7600 MT/s, but in CL36 and with tighter timings. So we’re going to activate this profile and keep the 8000 MT/s frequency, and hope that it works.
And yes, it’s perfectly stable and we were able to carry out our tests under AIDA64 and Geekbench 3 without difficulty. The performance is particularly interesting for the single-core score.
Manual overclocking:
We’ve already got a series of profiles in mind that we’re going to try and run. The idea is to further improve our scores. A good indicator will be to see if the memory score under Geekbench 3 increases again. Despite all our tests, our best profile remains at 8000 MT/s in CL32 with an FCKL frequency of 2200 MHz.
To finish on a high note, we combined our OC profile for the processor with that for the memory. While the Cinebench R23 score hardly varies at all, this is not the case for Geekbench 3. The single core score rises from 9588 to 10674 points (11.3%) and the multi core score from 69221 to 74101 points (7%).
Now that we’ve taken a full look at the performance of this AMD Ryzen 7 9800X3D processor, it’s time to give you our impressions of the latest addition to the AMD range.
