Question Max RAM speed for i7-9700K

[HadMatter]

This Tom's Hardware article talks about non-K series processors being limited to RAM speeds of 2666.

Want the fastest RAM speed on an Intel platform? Get a K-series CPU.

Non-K-series Core i7 and Core i5 processors have the same DDR4-2666 limit as that imposed by Intel’s lesser H370 and B360 chipsets. Core i3 processors have a lower limit of DDR4-2400. While most boards lack XMP, those that have it will more easily configure XMP memory with enhanced timings.

I'm planning on buying an i7-9700K, but I notice that the specs state a "memory type" of "DDR4 2666". Does this not indicate a 2666 max speed? Maybe the 'k' in i7-9700k doesn't mean it's a k-series like I assumed. Just trying to understand. I mean, I wasn't planning on getting the fastest ram out there or anything, but I also don't want to pay for something I can't utilize.

2666mhz is what Intel states the CPU can support. Running ram above this speed is technically overclocking and requires a z series motherboard.

Ah. Got it. Thanks.

I have an i7-9700k on an Asus z390-A motherboard, Corsair 2x 16GB 3000Mhz memory. It runs at 3000Mhz with xmp1 setting fine, xmp2 setting is unstable. CPU is clocked at 5Ghz.
