AMD Ryzen Sample Hits 5 GHz OC on Air

/ 2 years ago


Earlier in the month, we got our first full review of the upcoming Ryzen processor. CPC Hardware, a French magazine publication, managed to get their hands on a Ryzen engineering sample and run a whole suite of tests on it. In a hidden easter egg just discovered, CPC has revealed their maximum air overclock on their Ryzen sample.

In a cryptic string of binary code, CPC left this hidden message “[email protected]=5G”. Considering that the sample only ran at 3.15 GHz base, 3.3 GHz all core boost and 3.5 GHz for the single core boost, 5 GHz is pretty good. This raises hopes that AMD may be able to blow past their 3.4 GHz target and push for high stock clocks.


Of course, this cryptic statement leaves a lot to be desired. For one, we have no idea how this overclocked was achieved. Was it a one-off run that kills the chip, are the voltages sustainable 24/7, what is the load temperature and how stable is it? We also don’t know if AMD’s new SMT was enabled or how many cores manage to hit that speed. Lastly, we must also consider the fact that this is an engineering sample, but this should be a positive fact since ES tend to run slower than retail samples. Overall, it does paint a picture that Ryzen and Zen has a lot of overclocking potential and AMD has not sacrificed too much clock speed for the IPC and efficiency gains.

    ^ Is written twice.

    I remember first seeing this on Reddit then in the comment section on WCCF as well…….this is interesting.

    Plot twist: the cat of the editor at CPC pushed the 0 and 1 keys on the num pad a bunch of times while he was in the bathroom and he didn’t notice.

    Could be bs? Isn’t this the same nonsense that was said about the rx 480 hitting 1500mhz on air? The only difference is we know the fx 9590 could boost to 5ghz but its base was 4.7 and still unstable. I highly doubt it’ll work on air and even water cooling seems unlikely to hit those clocks reliably

    Norlt really impressed, I have a pair of x5690’s that run steadily at 3.96 GHz on air, with load temps of 45 degrees Celsius. With an Oc’ able Mobo, I’m reasonably certain that these would reach pretty close to 5 without much stress.
