alder lake ddr5 RAM speeds

[dave28]

Does anyone know what DDR5 RAM speeds are safe to use daily for an i5-12600K.

As in not going to damage the lifespan of the CPU in any way.

I tried looking this up but found a confusing mess of information.

My RAM kits XMP profile is 6600mhz C32 and is 1.4v i think.

I ran it fine with a 13700K but have just switched to the 12600K.

Why would you be worried about shortening the lifespan of one CPU with a faster kit of memory over another CPU?

The memory controller on 13th gen is stronger than 12th gen but that's about the only difference that I'm aware of.

I wouldn't worry about memory controller degradation too much unless you're pushing very high volts (north of 1.5v) and you could always start at 1.4v and then reduce the voltage until you hit instability.

A quick look suggests keeping DDR5 below 1.4v but there's nothing to suggest that that would vary based on generation of CPU.

The 12th gen was the first intel CPUs to support DDR5 so i imagined that the memory controller may be very weak or something and was worried that i was pushing it well beyond what it was designed for but i honestly dont.

RAM has always baffled me, i find it so confusing and intel only say that it supports 4800mhz which is about as useful info to the consumer as saying a car has wheels.
