OnePlus RAM DDR Bus - OnePlus 7 Pro Questions & Answers

I found DDR Bus in OnePlus 7 Pro to be 451 (1804 MHz) supposed to be 533 (2133 MHz). Also in Android Pie the I/O scheduler was CFQ, now on Android 10 they changed that to Noop. Does anyone has any idea why?

Which cpu freq are best?

Xperia X10 mini pro [MOD] FroyoComb v1.2
What is the best cpu frequency for stabile working, i use set cpu app for this.
I use 'coservative' scalling Min: 768 Mhz (when some problems i reduce to 748MHZ or 600Mhz when i dont need more performance) Max: 787 MHz or even 808 Mhz but this freq is too high. Is this scalling are good or use different (ondemand,performance)
Also i have question when my phone is blocked (screen is off) cpu freq back to normal low freq or still have the same freq like in set cpu app ?
No one can give specifics as even with one model of phone the quality of CPU changes so set frequencies differ.
EG: i'm using DHD with 1.6GHz OC "smartass" but some users top out on 1.3GHz, could OC more stable but don't need, regards underclock i've screen off "Powersave" lowest frequency 245MHz don't forget to set priority high.
There is more you can do with set CPU such as underclock on less battery so know get more for criticle phone usage, also temp based so again saving power.
Anyway best bet is to look for other users of x10 and see what they top etc.

[Q] Power consumption of Qualcomm MSM7227A ?

I want to know the power consumption of Qualcomm MSM7227A, on 1 GHz.
I have the power_profile.xml info, obtained via this program - BatteryViewer by TKY.
For my Galaxy Mini 2 with MSM7227A (800 MHz) this is the information:
245 MHz - 30 mA
320 MHz - 50 mA
480 MHz - 80 mA
600 MHz - 100 mA
800 MHz - 180 mA
I want to overclock it to 1000MHz but I want to know if it's worth it. If the power consumption is too high, it would better to leave it at 800 MHz.
So, if there is anyone with Sony Xperia J, HTC Desire V, Galaxy Ace Plus, or LG Optimus L7 (all of them have MSM7227A at 1GHz) can you please tell me the declared power consumption of this CPU at 1GHz.
Anyone is welcomed to share their info so we can know the general power consumption of different CPU's.
I have a galaxy ace plus overclocked to 1.3GHz, and it seems to consume up to 600 mA. How to find out consumption at lower frequencies? I have to set max freq to lower, use it for a couple of days and check the stats? Or is there any simpler way?
The only way that I know of checking power consumption on Android is via factory written data in power_profile.xml.
Go to PlayStore, find BatteryViewer by TKY, install it. Then click the left button for options and click Power Profile.
For example you'll see something like this:
...
cpu.active 0 180.0
cpu.active 1 100.0
cpu.active 2 80.0
cpu.active 3 50.0
cpu.active 4 30.0
...
cpu.speeds 0 800000.0
cpu.speeds 1 600000.0
cpu.speeds 2 480000.0
cpu.speeds 3 320000.0
cpu.speeds 4 245760.0
....
How did you found out that your Ace uses 600mA at 1.3GHz?
=========
EDIT!!!
This version of Antutu didn't work properly on my phone. It didn't took into account the SD card speed, so the I/O result is much lower, and so is the overall result. But you can still see the implications of overclocking on cpu, gpu and ram.
=========
I also noticed that performance of the whole system is not scaling linearly with frequency. It's possible on some higher frequencies the system to be slower overall.
These are tests of my Galaxy Mini 2 with Antutu benchmark:

I use Battery Monitor widget, it lays out a plot of mA (usage) for a specific duration. In the plot the mA value peaked at 600.. Probably those were the times when I was using processor intensive apps.

That is probably battery draing for the whole system including cpu, radio, wifi, screen...
Can you please check the data with BatteryViewer and post them here.
Thank you.
cpu.active 0 0.2
cpu.speeds 0 400000.0
The rest are empty. I get the same values whether I oc or not. So what info can I decipher from this?

As far as I know, this file contains values from which the OS approximates power consumption for various components. They are fixed, factory predefined values.
Those values that you saw are default ones. It doesn't look your factory defined them. I have seen that on some phones there are no predefined values, so I don't know what's the deal.
What phone do you have?

[Q] Can some provide us with some advanced Geekbench 3 results?

You need root for this and probably need a way to disable the CPU clusters.
What is the Geekbench 3 results for the following?
Only A53 cluster with performance gov (locked 1.5 ghz)
Only A57 cluster with performance gov (locked 2.1 ghz)
You need to monitor CPU utilization in order to know that only the wanted CPU cluster is being used.
Core 1 - 4 is A53 cluster
Core 5 - 8 is A57 cluster
EDIT: when running Geekbench 3 normally, can someone check if all cores 1-8 are used by Geekbench 3 for the multicore result by monitoring utilization of all 8 cores during the benchmark. If all 8 cores are used there should be vey high % utilization on all 8 cores during some parts of the benchmark.
Thank you.

Why?
Short version
I'm interested in the CPU performance of both clusters separately because I manage my phone performance (Note 3) with the help of
Multicore CPU Control PRO, and SetCpu with profiles enabled on screen off/on and certain applications.
I don't find the stock settings responsive and smooth enough so I adjust them.

Underclock or undervolt cpu

Hello guys
How do we undervolt or underclock the cpu on the p20?
Another question ive noticed that the min freq for the Kirin 970 is 500mhz. Correct?

Big cluster gets locked at 1209 MHz

I'm having this problem with POCO X3 NFC where big cluster cores get locked at maximum 1209 MHz and it's impossible to change them back to 2304 MHz.
I'm using stock MIUI 12.0.8 (rooted)
I tried many applications for changing CPU frequency, and none of them can change it to above 1209 MHz.
Sometimes rebooting the phone fixes this, but after some time they again get locked at 1209 MHz.
Is there a way to fix this without reflashing the ROM?
