Yeah, I'll take a look; have been investigating this myself, but pushing up the cache speeds to 3200 MHz is hard for some of these CPUs. I am not sure that mine will even go that high with reasonable voltages; even getting 3000 is difficult, which a big change from my 6950X.
Also, getting under 55 ns is pretty hard as well, even @ 4000 MHz. Yeah, you can tweak secondaries and tertiary timings a bit, but it is also difficult to then manage the hard faults that will occur.
I do have some very capable ram, still tweaking it to find the best I can, and then I'll go more in-depth on 3D testing.
Reviews is a hobby for me though, so I only have so much time for doing stuff like this, while also having reviews to do, and, well, life with 4 kids.
Kids are back to school just today, so I'll have more time during the day in the weeks coming before I gotta get back to "work", and one of the things I would like to do is investigate this exact thing. I am also interested in if it scales with CPU speed, or where the "bottleneck" might be best "optimized"
