By the way, TechPowerUp has made an article analysing why their AMD 5000 series CPU reviews had gaming results that were so different than the ones from other sites.

Turns out that moving from a 3200 CL14 to a 3800 CL16 RAM kit and brought big improvements, and those improvements increased again moving from Turing to Ampere.

So what's the ideal RAM specs then? I hope someone will have a closer look at that with many different RAM specs.

We will know more once Gamer Nexus releases a follow up video with their findings, but until then this is what we know:

• Go for high frequencies paired with low latencies. A 3600 CL14 kit will perform about the same or better than a 3800 CL16 kit. Anything higher than 3800MHz is a hit or miss situation, and CLs 18 or above is a no go.
• 4 sticks perform better than 2 sticks, as long as both are equal in terms of ranks...
• Zen prefers to have 4 ranks of RAM. That is achieved through 4 single ranked RAM modules (mostly all 8GB modules are this way), or by 2 dual ranked RAM sticks (usually the ones with 16GB). The ranks are the sides of a RAM stick. If the memory chips are on only on one side, it's single rank, if there's chips on both, it's dual rank.

I've read that AMD will launch a new BIOS update that will make it easier for Zen3 to work with 4000MHz modules, but those have high latencies, making them a bit risky.

The RAM kit you had eyed and mentioned a few days ago was a very good choice, no need to change it.
