Just want to say all results are within margin of error and are the same for both resolutions 1920x1080 and 2560x1440 and will be the same for 98% of the PC games people play.

Want the best out of your system ram,fine tune Ram .I do not play at 1280x720 or 1920x1080. If you have normal gear tune your ram and put cash toward better GPU.

Tested a old game and new game at 1920x1080 and 2560 x1440 on AMD Ryzen 3800X.

The test is to show that tuned timings for your DDR4 Ram is more important than actual fabric clock on AMD Ryzen.

So for the people building a Ryzen system and can google or have a little knowledge, it may be advisable to pick a good value ram and tune up that ram or for the people with DDR4 3000Mhz ram there is no need to waste money buying DDR4 3800Mhz ram,thinking your gaming on AMD Ryzen system will be better.

I just could not be bothered testing a bunch of games ,as I have done this many times and results are always the same.

So I set CL12 DDR4 2933 Mhz vs CL16 DDR4 3866Mhz both have tight ram timings .

The memory clock (mclk), the memory controller clock (uclk), and the infinity fabric clock (fclk) are all synced for best results 1:1:1.
You can also run Ram at 1:1:2 and still have great results.

Of course I do not care what you do with your ram,I am just trying to help out someone who needs the help by showing actual video and how it does work when PC gaming.
