For that spreadsheet all you need is a CPU-Z validation. The CPU I used there is at edge of stability and with high voltage, most of the results in there are as such.
Had 3x R7 1700, from week 05 to 13 production, all reach 3.8GHz high stability using ~1.35V +/-0.02V. 3.9GHz none reached with high stability, even things like RB stress mode/custom x264 had WHEA errors, voltage was ~1.45V.
The 1800X I have, is using ~1.425V for 3.9GHz, week 10 production. TBH the 1800X IMO is best to run at stock as I didn't breach the XFR 4.0-4.1GHz clocks. At stock depending on temps/loading will do 3.9-4.0GHz on 2 cores. The stock 3.7GHz all cores clock is pretty good performance with high efficiency IMO, as it uses ~1.25V.
RAM on all I have gained 3333MHz tight, 3466MHz is about where you start to see which is better. The 1800X has no issue with 3466MHz C15 1T, but same RAM/Mobo, etc used with R7 1700 will not do same clocks/timings. I wouldn't say the R7 1700 is any lesser in IMC quality as I have noted some OCN members having better RAM setup on an R7 1700 than my samples.
