i9 12900k max supported memory type?

Hi,

 

Intel's website states that Max. supported memory type for 12900k is 4800 MT/s for DDR5 RAM. Wouldn't then the RAMs running at XMP speeds stress out the memory controllers on the CPU? What do these specs mean?

Official support and what the CPU is capable of are two different things. As for stress on the memory controller, that's not something you typically have to worry about, because xmp typically changes ram voltage settings and not soc voltage settings

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

It can stress the imc but that doesnt matter till youve reached max safe imc voltage for a ram overclock

 

Anything over 4800 is considered an oc but if you are running rams that pitifully slow then youre either an idiot or looking for tight timings cause slow ddr5 will get obliterated by ddr4

6400 seems to be doable for all cpus and some mobos atm, anything higher is not at all guaranteed oc or not
