Polaroid S8 (from Kohls Dec.2013) Stable Overclock @ 1.2Ghz/core.

Hey everyone,

I just got an S8 from Kohl's and it's loads better than last year's PTAB8000. My S8 is already rooted and I'm now testing stable overclock speeds. For those who bought this tablet, it's advertised to run 1.5Ghz. This is a complete marketing lie. The S8 by default runs at 720Mhz per core. Since there's 2 cores, they market that it runs at 1.5Ghz.... whatever!!!!

Anyways, using Voltage Control, I'm able to get a stable overclock of 1.2Ghz (per core).

Previous posts lists 1.15Ghz stable overclock but I figured... why not push it to a full 1.2Ghz

Anyone want to test with me and confirm this is a stable overclock?

By the way, for those noobs, you'll need Root to overclock.

I've tried SetCPU but the only problem is that when you increase the slider overclock in setcpu, it applies the overclock instantly. This is a problem with the S8 since the touch screen kinda sucks and it's inaccurate... (enable Show Touches under Developer Mode). With Voltage Control, you set the overclock and then you click apply so there's no chance setting an unintentional overclock.

I've used No-Frills CPU and the most I can get without crashing the tablet is 1.2ghz. After that it just locks up.

The default boot clock that is applied at post is 912mhz @ 1.4v.. The hardware is configured as follows..

Maximum Frequency = 912mhz @ 1.4v
Normal Frequency = 720mhz @ 1.2v
minimum Frequency = 600mhz @ 1.15v

This is set before Android boots.. There is an entry in the config files for 1008Mhz @ 1.45v.. The files contain 8 different frequency levels.. They are as follows..

1008mhz @ 1.45v
912mhz @ 1.4v
864mhz @ 1.3v
792mhz @ 1.25v
720mhz @ 1.2v
624mhz @ 1.15v
528mhz @ 1.1v
312mhz @ 1.05v

The default cpu governor for the device is fantasys. The device cuts power to the second core when it is not in use.. This will create an initial lag when the device us unused for a couple moments.. I am working on adding a new governor to the device that will make it more responsive..
