Hello all,
I have a rooted Pixel 3 and I am trying to customize my CPU governor with Franco Kernel Manager. The default governor is 'schedutil' and it has the following tunable parameters:
'downrate_limit_us' (default: 20000)
'hispeed_freq' (default: 0 Mhz)
'hispeed_load' (default: 90)
'iowait_boost_enable' (default: Disabled)
'pl' (default: Disabled)
'up_rate_limit_us' (default: 500)

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
What does each of those parameters do? I have been searching all day for documentation on these tunables, but to no avail (although I can imagine what the rate limits do). I have seen a lot of custom kernel on this forums so I presume the contributors here know the answer. Would you mind helping me, please?
Thanks in advance.
I'm looking for the same information... especially about "pl" and "rtg_boost_freq"
There's no documentation anywhere?

Hi,
I got Alien #3 ROM with faux123 1.1GHZ OC kernel.
Now the only thing i need to do is install SetCPU and set the max to 1100\minimum to 216 and check the "Set on boot" checkbox ?
Thanks.
Don't set on boot int'l you're sure its stable

1100/216 is perfectly stable. Very mild OC and the one everyone is using. If you are going to play with undervolting, or in the future are going to OC the CPU more as the ability to do so arises, then you will definitely want to ensure stability before setting anything to set on boot.
Is that profile good and should i add more ?

What are some good volatages to use for undervolting?

Start with -50 across the board then push it if its stable. Lower speeds.can.bbtake more. Note 100 is the most it will handle currently

for what? to clock the CPU changed from demand
Try a different kernel. I use Boeffla Kernel, and I can get up to 1600MHz.

Well frequency couldn't be reduced by under volting.. can it??
You have to reduce the frequency and that is called under clocking...

i found problem
solution was uninstall TDT 4.3 now everything works fine

Hey folks,
this is about a powersaving "Powerplan" for our Ryzen based systems.
I'm using a R9 3900X with undervolting for my daily stuff. I started to play around with the powerplan settings - thanks to QuickCPU tool...
So i created my own efficiency trimmed powerplan. I think it is well balanced and want to share this one with you.
First of all, i don't guarantee anything. All you do, is on your own choices and actions...
Second - i didn't test with any other CPU - but feel free to comment or post your results.
Here some guidelines:
- Just extract the attached zip on your pc - 2 files included - one .pow and one .cmd
Algorithm : MD5
Hash : 53945068405291750F77BAA347814016
File : Energiesparplan.zip
- Hit the cmd to install the powerplan
- Then activate the powerplan via system settings

I compared my powerplan against "balanced"

I hope u enjoy and have a nice day...
