I mean, cool and all... but practically unfeasable and performance wise probably no difference at all compared to a sustained 5GHz boost on all cores...

I wonder how people would react if AMD released a binned 7800X3DX (or whatever name works) with a higher price and clocks matching the 7950X3D maximum clocks.

Show us a B series MB with eclock and pbo boost!

No need to OC these, you will just ruin the efficency.

It's just irrelevant news at this point, records between 8 - 9 GHz on i9, AMD FX, and some older CPUs were done multitude of times, 5+ GHz is possible at home with semi-decent AiO on pretty much any hardware that is unlocked.

It's not possible. 7950X3D's v-cache CCD has the same clocks. The VCache on top is the limiting factor, it has to throttle hard to not destroy itself. -- Anyway I'd like to see the real world performance delta this OC actually delivers. The fact he reached 5.4GHz on single thread load is nice, but it doesn't say much. Is there link to some game benchmarks or something?
the vcache ccd on the 7950x has a higher fmax of 5250mhz, vs the 7800x3d's 5050mhz, and does boost higher. also here is the source: https://skatterbencher.com/2023/04/05/skatterbencher-60-amd-ryzen-7-7800x3d-overclocked-to-5400-mhz/ , about a 3-10% uplift depending on the workload over stock,doesn't really benefit any of the games tested. https://i0.wp.com/skatterbencher.com/wp-content/uploads/2023/04/Slide59.png?resize=1024%2C576&ssl=1 I don't see any down sides to doing this since it preserves the normal boost behaviour, this is akin to just increasing the fmax while using the curve optimizer. the cache harms thermals primarily, so if you are able to cool it , there is headroom.

Has anybody done comparisons between a 7950X3Dwith the non-3D-Cache-CCX turned off completely in BIOS vs. the 7800X3D yet?

Go to HWBot.com, then lookup his name skatterwhatever, then look for the cpu you'll see I'm sure he atlast posted it with CPUZ

Just goes to show that these chips just aren't designed for overclocking when all an experienced overclocker can get is 8-10% increase in clocks, it's not worth messing with these chips beyond applying a -30mv all core on Curve Optimiser, and then combining that with some memory overclocking and/or memory timing tightening. Running -30mv all core can reduce your max memory overclock though, but you should still be able to tighten the timings.
