Overclocking & Test Setup
Like the Ryzen 7 2700X, we overclocked AMD's 2700 to 4.2 GHz. While the lower-end chip did need a bit more voltage to get there, our 1.4V Vcore, 1.2V SoC, and Level four Loadline Calibration (LLC) settings are still within the safe zone for AMD's processors. They just make the CPU operate a little warmer than it would otherwise. Top the 2700 with a capable closed-loop watercooler and thermals won't be an issue. If you're stuck with AMD's bundled heat sink and fan, though, expect Ryzen 7 2700 to fall short of its best possible overclock. Our sample topped out at 4.05 GHz as it exceeded 95°C.
We did match the 2700X's overclocked memory settings (DDR4-3466 at 14-14-14-34 timings) with minimal effort. That's particularly encouraging since memory tuning dramatically improves Ryzen's gaming performance.
Precision Boost Overdrive
AMD isn't giving us much detail about its Precision Boost Overdrive feature, though we know it increases maximum boost voltage and boost duration. However, we also know that Precision Boost Overdrive is an AMD-sanctioned feature. Because this is a standard capability for Ryzen 2000-series processors, we leave it enabled. Conversely, we disable the Multi-Core Enhancement BIOS option found in many Intel-based motherboards because it overclocks beyond the company's specifications.
MSI X470 Gaming M7 AC
Our MSI X470 Gaming M7 AC has a PCI Express 3.0 slot with a x16 link, a slot with a x8 connection, and another PCI Express 2.0 slot with a four-lane link for graphics cards. Its four RAM slots support DDR4-2933 and scale quite a bit higher through overclocking.
The motherboard also provides two M.2 slots with PCIe connectivity. The I/O panel has a USB 3.1 Type C connector. The USB 3.1 and USB 3.1 Gen 2 ports support fast charging for smartphones and tablets. If RGB is your thing, MSI has you covered. The integrated RGB Mystic lighting allows customizable effects with several software-controlled zones.

The 65W TDP is low enough for passive cooling. That it is cheaper than the 2700X is just the icing on the cake.
For *my* needs, it is perfect. I am more than happy to lose a little performance and have the TDP drop 40W.
Now though, it would have been better if AMD had sold those without a cooler for $20 less - the price gap with 2700X would have made it much more enticing, and overclockers could have pushed the hell out of it with watercooling etc.
OMG, YOU GUYS ARE GENIUSES!
Your reasoning is the same logic I used in selecting my 1700 non-X. I am attracted to efficient power.
That's a LOT of vcore right there!
Thanks, good eye! fixed. (1.4V)

Main System(5-7 years) becomes Utility System(5+ years)
Unless of course you burn out the mainsystem in 3-4 years *factory overclocks tend to do this too). ;)
Where are the performance per Watt or Temp charts?
