An important note for all other users to take heed of! Cheers for reporting back that all was solved :thumbup:

My ASV is 7 I can undervolt to -75mV , more than that my phone gets unstable and start freezing , i thought i could undervolt more but in the end it's the quality of the chip

My Boeffla Sammy Ondemand Profile v4 - 30th July 2014



Introduction



This profile is designed to get the most out of Boeffla in terms of:



CPU Performance - Overloclocked to a universal and sensible 1.6ghz


GPU Performance - Overclocked on 3-5th steps, steps 1 & 2 at stock and voltage underclocked to keep system GPU activity battery friendly. - PLEASE REMEMBER THAT YOUR GPU MAY NEED 25mV or 50mV ADDING TO SUPPORT THE LAST 3 FREQUENCIES IF YOUR EXPERIENCE CRASHES IN GAME.


Streaming - Designed to keep Bluetooth A2DP stutter free - Guaranteed!


IO - Noop to ensure minimal battery impact and stable performance!
[/COLOR]



Specific design



Governor - Ondemand changes from stock values:


Sampling Rate - 80000

up_threshold - 90




IO Scheduler:


Noop - Best for battery life and stability
Read-a-head - 384k - Sensible streaming rate without causing excessive memory/cpu cycles




CPU Frequency:


My opinion is that 1.6ghz is a universally obtainable overclock value for the i9300, 1.7ghz can be problematic for some users, therefore I do not use it and the extra performance it offers is minimal.

No voltage alterations made from stock values as this is a device specific value that relies on the quality grading of your CPU, therefore individuals should alter their voltages according to ability of their device to handle such adjustments!




GPU Frequencies:


160mhz - Stock - Undervolted for general 2d application/UI battery savings at 850mv
266mhz - Stock - Undervolted for general 2d application/UI battery savings at 875mv
440mhz @ 1000mv
600mhz @ 1050mv
700mhz @ 1125mv




Boeffla-Sound:


Boeffla Sound - Enabled
Equalizer - Enabled
Saturation prevention - Enabled
Equalizer profile - Pleasant setting




Display+LED:


LED Blink Rate - 8



AC Charge Rate:


AC Charge rate reduced to 700mA - To match the basic supply ability of the terrible stock Samsung charger!



zRam & Swappiness:


zRam Devices - 4 (1 per active CPU core!)

zRam Total Disk Size - 120mb - After careful testing of values to find optimal value

Swapiness - 35 - After much testing once more to find optimal value!




Low Memory Killer:


LMK Values - Much testing performed to fine tune good values!:

Foreground apps - 20mb

Visible apps - 25mb

Secondary servers - 32mb

Hidden apps - 40mb

Content providers - 46mb

Empty apps - 59mb




Hope you enjoy, please provide feed back

One final thing with that, its well worth testing to see if you get the same performance and battery effectiveness compared to no UV, even before you make the phone freeze, there is normally a point at which the phone uses more power in corrective action when undervolting too much, you may find that -50mV give better performance and battery life. Well worth testing to be sure
