Comments
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

2024-12-11 01:17:18 +0000 UTCThank 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?

2024-12-11 01:14:49 +0000 UTCNone 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.

2024-12-10 21:12:58 +0000 UTCThanks 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.
