Actually Hardcore Overclocking (Buildzoid)
it should be relatively easy to run 2x32 at 6200 or 6400 and that should be about the same or slightly faster than 8000 depending on the workload

Thank you, cl38 did the trick. Do you recommend I stick to the 8000 or go back to my other sticks- ddr5 6000 2x32gb cl30? Benchmarks were similar, but with gaming the 8000 may take the edge?
Actually Hardcore Overclocking (Buildzoid)
None of the timings here are particularly tight other than the tCL. Have you tried CL38/40 at 1.45 VDD? I have a G.skill 2x24 8000C40 kit but haven't tried it on the Hero yet.

Thanks for your work on this. Is there a fallback/easy version of these? Having trouble getting these to run stable on my Gskill 2x24gb ddr8000+9800x3d, same mobo.
