Andrei is working on it.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
I haven't used that app, does it support Octa core cpu setups? The control of two separate cpu cluster max frequency is elaborate. I know System Tuner correctly implemented control of both clusters back when Exynos 5410 came out. You were also on Ultimate Kernel I think, did Faux app work for you on that kernel?
[Galaxy Note 4 Q&A, Help & Troubleshooting] MEGAX91:
i always use it for CPU/GPU OC ، CPU Governors ، ..........

setting are only available for a53 Cluster ( Ultimate Kernel& Perseus Kernel ) ، also there is no GPU clock controls :
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
Looks like it is just setup for $hitcomm I mean Qualcomm or a max of a quad core SOC only. No gpu over clock in Perseus, it just allows gpu voltage adjustments. 700mhz gets gpu hot enough in the few scenarios it is utilized in. Synapse works for min and max mhz for both clusters so I would just stick to that. You can script a governor change at boot and not need an extra app for it and on Ultimate Kernel I think you already have the governor option in Synapse as well. I would guess to get Faux control to work you would have to ask the developer to fix it and to my knowledge it was made for his own kernel Faux and likely a specific device set of compatibility like most Qualcomm chip sets or older Exynos Quad core chips and below. Eventually it may support S810 which is Octa core but that is neither here nor there...

[Galaxy Note 4 Q&A, Help & Troubleshooting] MEGAX91:
i found out that actually GPU is already working almost at the limit and in the stock kernel frequency under load does not rise above 600 MHz.( Maximum stock frequency is 700MHz )

gpu overclocking is useless.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
700MHz is a reserved frequency for just few cases where a lot of ALU is needed. You can learn more in the review of Andrei in Anandtech.
[Galaxy Note 4 Q&A, Help & Troubleshooting] MEGAX91:
i used 800&900 MHz frequencies for O.C but frequency under load does not rise above 600 MHz.

There is limit in kernel for GPU frequency : gpu_max_freq_limiter = 600

How To Turn off Exynos Cores

Edit : it doesn't work.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
Unlike Qualcomm design the chip doesn't hotplug the cores ie power them off under no usage. Because of the design of Exynos when there is no load on a core that core takes almost no power. They call it power gating vs hotplug. Most of the time you will have atleast one A53 core/thread active under load at all times because of backround processes. The cores with no load are not really taking power since they are power gated. Disabling cores doesn't really optimize this chip.

Having the extra cores available allows in most cases to keep overall mhz lower on any given cluster. When we used that app to disable cores in the past we saw a higher average mhz used because the core load would cause the governor to scale up more often which actually would lead to higher power consumption because of how high the voltage rises for higher performance mhz available to the SOC.

Load up Basemark X

https://play.google.com/store/apps/details?id=com.rightware.BasemarkX_Free

Set to High Quality from Medium

Give a run with cpu/gpu temps low and battery temp as well. I don't know exact temp the max gpu gets throttled but personally try for under 30C battery and under 60C cpu/gpu temp.

See attached screen shot 700mhz gpu shown. Cool Tool to monitor with and A57/gpu speed are shown using custom labels in cool tool

This one done on stock 5.0.1 and had same result on 4.4 with Perseus loaded. The limit is more power/temperature related. Start the same test with a hot phone and the same area 700mhz gpu was used easily can see 4-600 range and if gpu has been active awhile we already know DVFS will drop us to 266mhz gpu to keep overall device temperature down especially battery/skin temperature of the device.

Please add Gamma Calibration to you're kenel.
[Galaxy Note 4 Q&A, Help & Troubleshooting] SaschaHa:
On Note 2 the Perseus kernel gave me the ability to do so by changing some values with (I think) STweaks. Haven't tried Perseus on my Note 4 yet, but maybe it's possible with Synapse. Search for values like CPU up- and down threshold and test some other values. In my case I rised this both values and minimized some values regarding the intervall... don't know the exact names anymore.

You will not get only one kernel active, as the "little" A53 cores are too slow for handling this amount of data. But maybe you get only 2-3 active for some situations :) On Note 2 I got a better performance and a plus of more than one hour screen on time with some modified values, as there was mostly only one core active. Will test it on my Note 4 in a few days, when I've time for it :)
[Galaxy Note 4 Q&A, Help & Troubleshooting] mkim055:

[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
Move the discussion elsewhere, I'm not integrating other governors for good reason.
[Galaxy Note 4 Q&A, Help & Troubleshooting] MEGAX91:
may i ask why ? ( i'm facing lag with stock interactive governor )
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
You'll get bad battery life. If you have lag with the stock one you're doing something horribly wrong.
[Galaxy Note 4 Q&A, Help & Troubleshooting] MEGAX91:
with intellective or Bioshck Governors i've got way better battery life ( without lag ) compared to stock interactive.

even mcaserg confirmed it.
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
That's a meaningless statement.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
Just to confirm from my own user experience NO lag on stock unrooted or Perseus kit kat on stock governor and none on Lollipop stock governor for my N910C. Im just using stock rom to test and for daily use. The lag could be a few things. Slowly remove modifications one by one and you should find the source of the lag megax91

Since there are touch boosters and interactive governor by nature boosts to the high performance frequencies when user is active ie why it was named interactive as it especially boosts speed particular with user activity and not just workload. So I think what Andrei says makes sense as there shouldn't be any lag with this sort of scaling in the majority of tasks we can do on our Androids.

This is just my humble opinion.
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
The stock interactive governor is highly modified for bL and intertwined with the scheduler and power allocator. And yes there should be no scaling problems due to all the boosters. Anybody still using custom governors without full PM understanding is guaranteed to see a degradation in power.

Also bad news is that unfortunately I didn't manage to finish the lollipop upgrade today and I will be busy till next Friday as I'm covering MWC in Barcelona.

I just want to get like 7 hours in a day with every day usage, I think I'm gonna do some undervolt -50 for start.

You can recommend me another value to under volt.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
If you want to target the hardware using the most power try to work down your A57 cluster voltages as they use a lot of power at full speed and create a lot of heat. The gpu could effect screen on time a decent amount too so you could try adjusting that second. If your doing light reading the cpu and gpu aren't used quite that much so it really depends on your usage patterns.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
Hi Andrei I hope MWC went well and looking forward to your Perseus Lollipop build. Anything really stand out at MWC from the crowd?
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
The S6 edge is really nice in hand but I think the screen is a gimmick as you lose screen estate and people will realise that very soon. The S6 is a great phone. Sucks for micro SD. The camera is a large upgrade over the Note 4.

The M9 isn't as comfortable as the M8 and pretty much not even an upgrade in anything and might have worse battery than the M8 due to S810.

The vive is the best VR around but couldn't use it myself due to media limitations.

The Gear VR sucks donkey balls. Don't buy it.

China has an enormous amount of phone manufacturers you've never heard about.

MediaTek has a bright future.

The new Gionee looks great.

MWC food is really good.

Also I have a few things to catch up to, one also being an Mx4 / MT6595 review. I'll try to migrate to lollipop over the week.

Can you Add GPU clock control interface & reduce GPU throttle levels , in LP version ?
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
Reducing throttle levels means making the GPU slower, I can look into that yes. I won't include clock control though, you shouldn't run higher than 700MHz.

Here's the Lolipop update. I still didn't manage to get a proper init sequence at boot for whatever reason. So for now I'm putting it up and people will need to manually execute /sbin/init-boot for Synapse to work. I will update the ramdisk later when I figure out what's wrong or what changed with Lolipop. Is 5.0 out for the 910U? When it is please send me kernel image and I'll update for that device too.
[Galaxy Note 4 Q&A, Help & Troubleshooting] MEGAX91:
sorry my mistake , i mean increasing throttle levels for GPU. ( higher than stock but less than U.K Just like Sky kernel )
