Not sure if anyone cares but here's what I gathered from testing this weekend:
I think that these HOS bypass clocks are most likely not worth it for Erista users unless you are extremely into 60fps mods (where it doesn't help much IMO) and not care about how long your console will last you.
From my testing, the only game that I appreciated the higher CPU clock from (2091mhz) would be Minecraft in 4 player split-screen. (it even maxes out 2 cores at 100%) Most games don't need that high of a clock rate.
I was able to go down as low as 1225mv (stock is 1120mv?) on CPU for 2091mhz, going lower would decrease CPU speed.
Games that already run poorly with 921mhz GPU will not run any better on 998mhz. (it's maybe a 5% difference and going higher is potentially dangerous.)
+ my fan was much more active on 998 than it was on 921, which might be due to much additional voltage applied in the patch. (not sure where Kazushi got these voltage numbers from, haven't done any test with going lower in voltage.)
The biggest gains were from RAM overclocking, where 2131mhz really helped a lot with Bandwith-bottlenecked games like Minecraft, Hyrule Warriors AoC, Xenoblade 2. games in general load faster too.
Overvolting is needed in some (most?) cases, not sure how that affects the longevity of the console.

Mariko units might be a different story, as those are able to reach much higher clocks with less risk of bricking (due to lower power draw), but they sadly cannot overclock as much on RAM as overvolting RAM is not possible (yet?).
