I've always been under the impression that anything above 2400MHz for DDR4 is considered overclocked or outside standard specs.

Then I guess we have a bunch of laptops with overclocked ram out there.

Nope, anything above the listed supported speed on specification sheet is considered overclocking. Check Intel ark and AMD's product pages.

Examples:

9900k: https://ark.intel.com/content/www/us...-5-00-ghz.html
Memory Types: DDR4-2666

10900k: https://ark.intel.com/content/www/us...-5-30-ghz.html
Memory Types: DDR4-2933


3800XT: https://www.amd.com/en/products/cpu/amd-ryzen-7-3800xt
System Memory Specification: 3200MHz

Also I bet your referring to running quad channel for any IMCs you've killed, or you bought ram with a really high xmp profile. This would be different if they had limited this change to quad channel configs or a more reasonable cut off.
What about the 4200 ram? Damn!
Think I'll pass on Intel for a while. AMD is getting better, I just got one of those "XT" chips and it's almost satisfying.

4650 Mhz stable. That's a step up from 4375..

That's exactly what happens when you run a XMP profile, the IMC is stressed. I killed a 3770K IMC with 2133Mhz Mushkin memory. The B DIMMs weren't recognized, RMA'ed it and the replacement still works fine. The two others I killed were 2 6700K. One of them couldn't even run 3200Mhz CL16 out the box. It all depends on your luck on how well the IMC overclocks.

The 3930k/4930k I owned both had no problems.

I've built multiple systems with 3200mhz ram and never had an issue except with a quad called 6th gen CPU, but to argue speeds beyond 2666 and 2933 are stressing a standard tenth gen CPU is just laughable.

We would need a large batch to test it, my 9900k can't run anything above 3200Mhz stable even though I have a 4133Mhz kit.

Yeah I've always found it to be a bit of a crap chute. My current rig I have no problems luckily.

Memory overclocking gets a bit annoying when you have a terrible IMC on a chip. My third 6700k can run this 4133Mhz kit at 3600Mhz stable.

Did you get those two switched or is the chip really so bad it runs your kit below rated speeds? I gather from context it's the latter which would really stink. Considering the 6700K was a flagship product and all...
