CPU Memory Speeds

[BotherRed]

So just wondering, it the max memory speed is 3600 for a full rack. Is there any point for buying something faster? I know tighter timings are good and size is another thing.
Just am wondering if there'd be any benefit to buying a kit that say for example is 4000. Would there be any possible benefit from that. Thinking more so about just buying at that speed if slightly above it and just maxing out size.

It's always possible it'll overclock higher and work. But if it doesn't, then there's no point/benefit to a kit that could theoretically go faster.

The official max memory speed is generally not the practical max memory speed. With Ryzen 7000 (where I'm assuming you got that screen shot), 2x2R configs and 4x1R configs both top out between 6000 and 6400MT/s depending on how good of a CPU you got, even though officially they shouldn't be able to clock anywhere near there. The official max memory speed just exists as a protection for AMD, where if you're trying and failing to run a higher clocked memory config, you can't RMA the CPU unless it fails to hit those official speeds. 

 

4x2R though is a nightmare to run, and while you can try to run it above DDR5 3600, you aren't gonna get much higher than 3600. You'll generally top out around 4000MT/s at the most, and odds are your memory controller isn't gonna be able to handle that.

You assume correctly.
