Sounds like an issue with the linux distribution. Try using a 'failsafe mode' if there's an option for one.

I run 8GB x2 in one of my S920s and 16GB x2 in another with no issues. Both of mine have the graphics card.
I have the 424cc cpu in case that makes a difference. Honestly, it sounds like a motherboard issue vs a memory module unless you weren't 100% sure the modules you tested were good.

You write about S920 again, I'm confused.. does your device really say "S920" on the label?

I think the Futro model with the AMD G-Series GX-424CC is a S930, not S920, but there seem to be mixed results and descriptions on the internet. At least the Fujitsu spec sheet lists the AMD G-Series GX-424CC as being used in an S930, maybe the other websites got it all wrong, could be, I am not 100% sure. My S930 has AMD G-Series GX-424CC (quad core), while all my S920 are dual cores (AMD G-Series GX-222CC).

EDIT: Correction, the AMD G-Series GX-424CC is indeed listed for both models, weird! o)

As you can see, single iperf3 is heavily bottlenecked by single-thread performance on the Futro.

With four parallel streams over the -P4 switch and cpufreq governor set to performance, i've archived full 10G, utilizing 258% CPU, so each core had like 65% Load. I still need to find a dual 10G card and do a loopback or nat test to see if it could route (or at least bridge) 10G.
Sorry, could you explain how to use all the cores ? which is the OS ? Do you know if a bare metal Router Os by mikrotik would be 4 cores capable ?

@tbfutro22 @Samir @boerni666 Guys, thank you so much for your help with the RAM. The list of modules that you use in your S920s was very helpful. As I mentioned previously, I bought RAM from @tbfutro22's list, and this model works perfectly. I can confirm that I found an incompatible RAM module for the S920. Once again, many thanks for your help.

Yes, it is the s920 which did come with a 424cc in certain models. In fact, what's interesting about the s930 is that it looks almost exactly like an s920, almost like Fujitsu just changed the name and that's it. I even have two s920s and they're both 424cc.
