Tuned ram timing on Ryzen as mentioned is always very helpful. I see people buying all kinds of different sets of ram looking for the best in PC gaming. Thing is tune your ram best as you can and buy a better GPU for those extra PC gaming FPS. Not sure if Fabric Clock @ 2000Mhz will make a huge difference for those willing to tune there own timings on the ram.

Some testing ram I did awhile back

AMD Ryzen Fabric Clock 1467Mhz (DDR4 2933Mhz) vs Fabric Clock 1933Mhz (DDR4 3866Mhz) PC Games

Battlefield 5 1920x1080

A free 2% seems fine, and I'd be curious to see CPU benchmarks, as this is more about CPU bottlenecks rather than GPU bottlenecks, although your widescreen 1080 resolution is usually more CPU bound than GPU especially compared to 1440 or 4k, so I'll concede that.

GamersNexus noted the following in their infinity review;
"3600MHz is the clearly defined limit of easy performance gains from memory frequency on Ryzen, and we saw our 3200MHz CL14 TridentZ RGB kit perform at nearly the same level as G.Skill’s 3600MHz CL16 kits in most tests when using XMP--timings are important. For what it’s worth, we didn’t see glitches or huge performance losses past 3600MHz in any of the tests--performance just stops scaling or takes a minor hit." For clarity, his last line is because the cpu they were using cant get above 1800 IF.

I havnt watched your video, but what CL was the 3866 at vs the 2933? Tightening timings with Zen2 is nearly as important as just 'raising speed', especially if you're just using XMP set-and-forget.

I only play PC games 4K so the ram does not do anything for me. I just did the test ,to show people on Ryzen tuned timings was the way to go instead of buying xxx faster ram, grab a better GPU.

I understand the timings is will not be achievable by everyone.,there just tossed together to make a point on PC gaming contrary to all the stuff people say about getting faster Ram on Ryzen for better PC gaming experience.

Ram settings in those test.
