Well, there's already information available: http://forum.pine64.org/showthread.php?tid=389&page=5
Have fun with liquid cooling and trying to fry the A64 at 1.5V
BTW: In the wiki there's just an image that might help you find heatsinks of appropriate size, there's nothing written about any limitations or what to do to ensure reliable operation. In the aforementioned thread you'll find a link to a Github issue where might be able to learn about the relationship between performance, heat, voltage and reliability. If you're not willing to try to understand that you should not even think about OC at all.
BTW: What's your use case for overclocking? Will you do number crunching? Tuning compiler settings and optimising code usually helps a lot more than stupid overclocking
Trying to do some Android Gaming on it, Angry Birds 2 is just plain bad on the Pine64 with 10-15 FPS.
Having read all the info regarding cooling the board (heat sinks, fans etc) as well as powering it with a capable PSU (micro USB or preferably via Euler bus) I was wondering if there was a way to unlock 1.34Mhz clock speed on Android.
The highest number I get with CPU-Z is 1.152Mhz. I mean, provided that I power the board via Euler bus and attach a good heat sink (and even a fan) would I be able to reach the top clock speed in all 4 cores?
Is there a limitation at 1.152 on Android build or the bottleneck here is amperage and temperature?
