Hey there!
So i'm thinkin upgrading from 32gb 3600mhz to 64gb 4000mhz with an i9-10900k cpu, and from what I can tell from what people been sharing with me here it's kind of a silicon valley lottery whether its gonna work or not.
Is there anybody here who have experience trying out this build. Did it work for you?

p.s. running it on a MSI MAG z490 tomahawk which supports up to 4800mhz

but my cpu.

You mean the 2933 Mhz max supported by your CPU?
Specs: https://ark.intel.com/content/www/u...0900k-processor-20m-cache-up-to-5-30-ghz.html

If so, this metric is default/standard and doesn't mean that your CPU can't handle faster RAM speeds.
E.g if you look the clock speeds, it says Base 3.7 Ghz, Turbo 5.3 Ghz. <- This doesn't mean that CPU can't run any faster than that. It can, with OC, just fine. How much, depends on silicone lottery and cooling you have.

And with RAM speed, same goes as well.

For example, my Skylake build (full specs with pics in my sig), has i5-6600K, which by the official specs, supports up to 2133 Mhz RAM,

Yet, i have 3000 Mhz RAM running in my system without issues. HWinfo screen:

RAM Clock is 1503 Mhz, since RAM is DDR (Double Data Rate), actual clock (frequency) is 3000 Mhz (3006 Mhz).

If you were to believe only what CPU "supports", then this, running 3000 Mhz RAM on CPU that supports "only" 2133 Mhz wouldn't be possible. But since it isn't so, it is possible.

Thanks a lot! That made everything clear :)
