[SOLVED] max ram speed for i9-12900kf

[TheCapitalistSpy]

Hello,
I was wondering if someone could offer me some insight on rams speeds. My motherboard supports of the 5600mhz ddr5 but I have read on reddit that the 12900 can only support 4800mhz ddr5. Is this true? Thanks in advance!

"Officially"...DDR5-4800

Anything past that is "Overclocking". And will vary (to a degree) from chip to chip. Also, CAS latency will be a factor.

DDR5 Memory Performance Scaling with Alder Lake Core i9-12900K

In this article, we take a closer look at the performance scaling you can expect for various DDR5 configurations. We test from DDR5-6000 all the way down to DDR5-2400 and compare CL30 vs. CL36 vs. CL40. Last but not least, we also consider these numbers in relation to what DDR4-3600 offers.
