[SOLVED] Does (higher) AMD CPU TDP help on memory overclocking?

Hi all,

I was choosing between Ryzen 5 3600 and 3600X, and after reading all the reviews about "The X don't worth It" i began to wonder....

Could the 95w TDP from 3600X actually make my life easier at achieving stability on memory overclocking?

I don't know, what if that extra power helps the IMC handle faster frequencies and tighter timings? Since the controller is built into the CPU...

Can anyone shed some light over this matter?

Agreed with above. TDP is referring to the power that is dissipated as heat and is used for the cooler, not the power draw of the CPU. In fact the actual draw often exceeds the TDP in actual application.

The other thing to consider is the 3600X is technically better, and does (I believe) come with a better cooler. However it's just usually the little price hike isn't worth the difference in performance.

I opted for the 3600X myself because the price difference was negligible at the time.
 
certainly if one were utilizing any 65 W BIOS imposed TDP limit, one would be hit that 65W wall fairly quickly, and clock speed would be limited at least a few hundred MHZ less... (I'd expect RAM clocks alone to only contribute a few watts here and there)

As for overall clock speed potential, it seemed the X models might eek out an additional 25-50 MHz on average manual overclock... (You can find some Der8auer stats on Youtube)

X models are just higher binned non-x. At same frequency and voltage both would have same TDP

Ok, so the 3600X doesnt draw more power (or has more power draw headroom) than the 3600, and/or that doesnt affect memory overclock?

See that in not talking about CPU overclock, im more interest about which processor is better for RAM Overclock.

Zen2 architecture: chiplets. The IMC of all the Ryzen 3000 CPUS are on the I/O chiplet, not the CCD chiplets (CPU core complexes). The I/O chiplet is mfg'd on an entirely different process and, being located distantly from the cores, therefore less affected by heat they generate. So heat resultant of overclocking the cores should have no effect on memory overclocking.

That doesn't mean all IMC's will overclock the same but I'm pretty sure most have been able to get capable memory to 3600/1800IF. Pretty much optimum for the system due to a variety of reasons.

If i'm looking forward a OC my RAM to, say, 3800mhz (IF1900) and CL15, on STOCK CPU settings, that means no extra heat from cores, could the 3600X add to the stability of the RAM?

Again, guys, i don't pretend to OC the CPU, cause im pretty convinced that It doesnt worth the effort. Overclocking the RAM, differently, seems to delivery some solid performance upgrade.

So which processor could be a better choice to help me overclocking my RAM sticks: The 3600 or the 3600X? Or it doesnt make any difference? (on RAM overclocking)
