Cryptic rumour points to air cooled AMD Ryzen hitting 5GHz

This is a follow up to our story on Tuesday regarding the publishing of the first 'official' AMD Ryzen CPU (Engineering Sample) review by French tech print magazine Canard PC. Since the magazine has been out and pawed over by its purchasers, more details about Ryzen have come to light. However, the most stirring extra piece of information is mysteriously hidden inside a binary string printed nonchalantly above a feature image on page 10 of the magazine's printed article (see below).

Reddit user lolwut996633 was first to notice the 0s and 1s were more than an ornamental flourish added to the image of a CPU and motherboard. The 0s and 1s sequence was as follows:

010110100110010101101110010011110100001101000000
010000010110100101110010001111010011010101000111

Putting the above string through a binary to plain text converter results in the following:

ZenOC@Air=5G

So there you can see it, plain as day. The Canard PC review editors have slyly hidden the above eyebrow raising statement - suggesting that their engineering sample Ryzen CPU was capable of hitting 5GHz with traditional air cooling.

Unfortunately this brief message raises many questions about how attainable and sustainable such an OC is. Did they overclock the processor with all cores enabled or not? What kind of voltage was required? How hot did the processor run? Finally there is, of course, the question whether this cryptic binary tease might even be just a meaningless joke…

I'm going to call BS. These cpus will NOT reach 5GHz on air. Highend water loop maybe and only for benchmark test. My 2p FWIW.
I reckon the 4C/8Ts hit ~5GHz, that wouldn't be too unexpected. I don't think the same applies to 8Cs and 8C/8Ts though, if they could get that high on air then AMD would be selling them at a lot higher stock speeds than 3.4GHz.

Why not? Some of AMD's Richland APUs could reach 5GHz on air as well as a handful of “lucky” FX 8350s at 5GHz on air too. I imagine the lower spec Zens should be able to match this and do so more readily.

Some (14nm) Broadwell could reach 5Ghz on air so it's not beyond the realms of possibility that Ryzen (also 14nm) could reach similar levels, especially as Ryzen's a newer design than Intel aging Core design.
How did they cool it? Does AM4 use the same cooler mount as an earlier AMD mobo, or was this the wraith cooler in action?
