64GB Corsair Dominator Platinum RGB DDR5 6400MHz CL32 Dual Channel Kit (2x 32GB) by Corsair

I bought it for... the looks. Corsair made a unique looking RAM, that I found appealing for open frame "industrial type" PC builds.

These specific modules won't run with 12700 CPU at 6400Mhz on ASUS Z690 board. At least, not with XMP (I, II, Tweaked). 4x32GB will run at 4000Mhz only in auto, and 2x32Gb will run at JDEC 4800Mhz.

I was fully aware that this may happen before I bought the memory.

I don't know/not sure if 14900K will change things, and generally, I don't care about speed at all. I saw no difference between DDR4-3200, DDR5-4000/5200 in my CAD renders (for fun), or casual gaming. You can try to run them at 5600Mhz manually, but then... buy 5600 out of the box, if this is important to you and you want to save some money (and time).

Why then I bought 6400Mhz, knowing all this? No reason. Yes, we, "such people", exist! :)

If you are into speed and best performance in gaming - this is not the ram you looking for.
For workloads, such as CAD, image rendering, editing or other memory consuming applications, quantity matters, not speed.

Random note:
I hoped that other memory brands will design at least something similar to this. Kingston had something far-far away looking similar (industrial, "metallic") with DDR4 renegade series no RGB, but their new DDR5-renegade is just too "horned" for my taste.
2 years already passed since I bought my first DDR5 kit from ADATA and nothing changed. Even Corsair made their new "top model" boring and somehow "forgettable". I really do hope that design of the Dominator Platinum will remain at least the same for future DDR6/7 releases.
