I recently had a mini crisis and ended up buying a 64GB kit of G.Skill TridentZ RAM (DDR5-6800 CL34) for my emergency AM5 build since my 5900X is failing. I found it for $360, which is a steal compared to the double price at my local PC store! I know that for AM5, 6000 MT/s tends to be the sweet spot, whereas it was 3200-3600 MT/s for AM4. However, I've heard XMP profiles often don't work with AMD CPUs. Do you think it's possible to manually downclock it to something like 6000 CL32? Did I make a mistake with this purchase, or was it a smart move?

Wow, you scored some good deals there! Just ensure to keep an eye on compatibility when setting up that RAM. Lower speeds should be manageable, but always check stability first.
Well, you might get it to work, but I wouldn't bet on it with XMP profiles. You can try downclocking to something like 6000 CL32, but be prepared for some tweaking to find stability through trial and error.
You're good to go to run them at lower speeds, but you will have to configure that yourself both for speed and timings. Getting it to run at 6800 could be tricky unless you're okay with performance hits. I managed something stable at 6400 with an AMD setup, but it required a lot of fiddling.
I think 6800 is pushing it too far for AMD systems. You'll have to set it manually, including the timings. It might take some effort, but tuning it down should be fine. Just make sure to test stability with software like OCCT.
