Overclocking

[g_t_j]

I was thinking to clock it to 1.5 GHz, you will NEED a heat sink for that, in the wiki said it is possible to overclock the CPU,GPU, and weirdly ram...

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?

Due to teh tablet and smartphone nature, the Android build always very conservative on CPU power adjustment and make dynamic core adjustment. Changing the DT can make the Android runs faster.

Thanks for your message TL Lim.

I have tried ''Set CPU'' and another ''over-clocking'' app but I only got to set governor to ''performance'' setting. 
I'm not able to go over 1152MHz. ''Set CPU'' sees another 2 frequences (1.2 GHz and 1.4Ghz) but can't set any of those 2. On the contrary, I can set a low limit frequency and the board remembers the setting after reboot as well as the change in governor mode.

If I get to unlock 1.4Ghz it would be a real benefit for me as I just need a small push in performance right now. I have no worries for high temperatures as I use heat sink and fan and the temperature never goes over 60 degrees under full CPU load. 

I will now make a USB to 2-pin JST connector to power the board through Euler bus, hoping that the extra amperage will help the board to get a leap in performance. 

Probably a utility will help unlocking highest recommended frequency or even better, allow mild over-clocking. 

BTW, have you received my PM?
