I set my 2x8 Crucial DDR4-2666 to 3200Mhz and matched the Infinity Clock for it. Upped the voltage to 1.35V and lowered timings to 16-18-18-18-36 as suggested by Crucial.

While AIDA64 is showing a faster Read (46178MB/s vs 37867MB/s), together with lower latency (73,8 vs 84,8) performance of various games and Heaven Benchmark are basically the same?

In PUBG the FPS for a certain spot of the map is 215-225 for both.
Assetto Corsa Competizione shows 120fps for the same spot on both.

But Cinebench and Unigine Heaven are actually a bit slower on 3200mhz.
Cinebench 3631 vs 3658
Heaven 3406 vs 3456

I am not using the right way to benchmark the performance difference? For example, should I do a play-through of the games instead of standing still to notice performance differences, or is something else going on?

HWINFO64 and BIOS are showing the correct memory speed, so it's not like the settings aren't applied.

Specs:

Ryzen 5 3600
Asus Prime B550M-A (wifi)
Crucial Ballistix BL2K8G32C16U4B
Sapphire RX 5700XT Pulse

You should check the 1% and 0.1% lows with MSI Afterburner. Those should definitely be higher with the 3200MT/s memory.

If Cinebench is showing lower score in MT test, then your 3200 setting is unstable. You should test it with TM5, karhu or another.

That difference in Cinebench is pretty insignificant really. You can easily attribute it to margin of error between runs.

As for real differences, it depends on the game. Differences fro 2666 to 3200 are pretty minuscule on average unless you have a serious CPU bottleneck, and they start leveling out beyond that. What resolution are you paying at?

With a Ryzen 5 and a geforce 1060, ram is definitely not your bottleneck. While the Ryzen 5 is a good CPU overall, its not the best CPU for high FPS gaming but more than that the 1060 is for sure your bottleneck here.

Edit sorry I was looking at the specs in your sig. Still I dont think you should expect frames higher than ~220 with a 5700XT in pubg.

System memory usage for gaming is almost negligible because the video card has Graphic DDR memory that is a lot faster than system memory. System memory handles the map change that runs in the background, that you can't see change on the screen.
