CPU clocked to 800Mhz

Aparently the CPU may only be clocked to 800Mhz........

If you got this from the Au website, Whirlpool, than I think they are talking about the iPhone 4, not the Galaxy S

well it's from the galaxy s thread and one of the guy who's doing the testing and stuff for samsung says this......definitely not iphone.
Guess just wait and see when it's released I suppose

huh? wat are you guys talking about? its 1ghz cpu

forums.whirlpool.net.au/forum-replies.cfm?t=1409745&p=58#r1152 is the link to the post where the user suggests it is 800mhz underclocked.

Yh, sorry, was reading a thread where they were talking about the iPhone being underclocked, just reading more, it seems it may be the case.
Will mean battery last longer, not such a bad thing, as long as it doesn't effect any of the performance of the phone

If they say 1Ghz then it is 1Ghz or else they're going to have a lawsuit on their hands. Nothing in between(except of course scaling).

I have the galaxy s and im pretty sure its 1ghz.. at least system panel tells me its 1ghz but singapore set are all 16gb model.
information from system panel:
ARMv7 Processor rev 2 (v7I)
bogomips 797.90 (may vary)
min clock 100mhz
max clock 1000mhz
on Nexus one using pershoot kernel but cpuset at 245mhz - 998mhz, it shows:
ARMv7 processor rev 2 (v7I)
bogomips 662.40 (may vary)
min clock 245 mhz
max clock 998mhz
so maybe the 8gb are down clocked?

Doubt the 8Gb version would be clocked lower. Thanks for posting your findings!

It's just the power of forums and the internet, allowing mis-information to spread at the speed of light

lol yep, looks like he was confused at the sliding clock speed....

when i ran quandrant standard it read armv7 processor rev 2 , max 1000 min 100
set frequency 800
is that normal
regards

It's 1 GHz, I checked the clock frequency with a monitoring application and it's dynamic but when required it clocks up to 1 GHz.

Wait, what?
The iPhone 4 may be clocked at 800mhz?
Can someone give source on this?

I don't have a link to that claim, but I think it was Gizmodo in their testing of the iPhone 4 and iPad noted the iPad did feel faster and the web browser rendered pages faster, despite both using the A4 processor. They hypothesised that it is the same architecture CPU in both, but different clock speeds.
After all, to get 10 hours out of the iPad the teardowns and x-ray scans show about 80% of the volume inside is all battery. If the iPhone 4 and iPad had the same processor, you'd think the iPhone's battery would be pretty bad considering the far smaller volume (although smaller screen not sucking as much power).
Wouldn't be surprising. After all, the Motorola Milestone / Droid has a mild underclock, as does the Acer Liquid to preserve battery life.
Probably cheaper for Apple to only have to manufacture 1 chip (the A4), but clock at different speeds appropriate to each device's battery life.
Apple doesn't focus as much on specs though, more that the user interface feels fast and smooth. If it achieves that purpose no need to worry about numbers, whereas since we have so much choice of handsets on Android specs do make a difference for us to know depending on our needs (eg: price vs performance vs battery).

My Samsung Galaxy S is running at 800mhz it sucks... i flashed it last night with the final build of 2.2 I9000XXjP6 for the Galaxy does anybody no how i can overclock it to 1ghz thanks People

The Galaxy S has a 1 GHz CPU. However, the clock speed is lowered while not needed to save battery life, just like on any modern PC. By default it is using the conservative governor.
The iPhone4 never was supposed to get a 1 GHz CPU. Apple never disclosed the number. But those who made benchmarks estimated the clock speed at about 800 MHz since is is about 20% slower than the iPad.

There is a Galaxy Lite version in some other countries that only maxes out at 800 Mhz
i think the guy reviewing the phone got it mixed up with that

He might have got mixed up, but the final 2.2 build for the Samsung Galaxy S is maxed out at 800 MHz for some stupid reason…. I’m going to flash it tonight again with a earlier build of 2.2 as I did some bench test and its only scoring a measly 900 points with the latest firmware installed.. Were as before it was scoring well over 2k…

Snapdragon 800 binning survey

Tks everyone. I think I have enough info and GPU OC has been work properly

PVS Binning : 3

No, but u phone still kick some butt on OCing:laugh::laugh:
Qualcomm produce same batch of chip for Snap 800 series and only use high binning chip to make further 801, 805....
To identify binning for each chip, they tested every chip.

Check using Pimp my Z1.
PVS Binning: 5

Variance in electrical components is very common, hence why some phones can handle overclock and undervolt much more than others

Freq table =340 ? 240?

I'm surprised you guys don't know this but we z1 users have a snapdragon 800 vv and guys instead of overclocking you should focus on undervolting and underclocking because even at 200 MHz GPU max and 1.6 GHz CPU max with -95mv undervolt I have no performance drops in gaming(dead trigger,avabel,etc) compared to stock except the heat has reduced and battery is a bit longer...
Lastly look at the screens in the post after the next post

PVS Bin

Update: I added a poll.
What do you guys have for PVS Bin.
PVS 5 on mine.
You do not need root, I used RootExplorer ironically enough.
Steps:
Go to sys/module/clock_krait_8974/parameters
Open table_name

PVS 7, bin v1
is it good or bad? lol

Higer the PVS number lower the voltages for the frequencies in the table.
However its not guaranteed that a higher PVS Bin CPU can OC higher than a lower binned part as they take samples when doing binning, so there could be lower binned parts that OC just as high as higher binned parts and vice a verse.
HD2Owner did a nice table here:

It is useful since it uses less power and heats less by CPU clock voltage ratio set by Qualcomm...
Ok just to be clear all are Speed 3 and v1 but PVS is different, mine is 8

PVS 8, you have nice one. I am usually on the low side with my luck on most devices lol.

PVS 8 for me too :good:

Pvs 8. What is the highest?

I believe it's 15.

CPU rev 2 or rev 3?

Was following the following thread on the Nexus 5x subreddit when I saw this: https://www.reddit.com/r/nexus5x/comments/3v45cf/my_thoughts_on_the_phone
It seems like someone has a theory that the CPU rev may be too blame for performance issues. You can find out your rev by running Geekbench. Let me know what you find!

Mine is Rev 3 and I have no lag whatsoever. I do have a bit yellowish screen, but I solved it by using ElementalX kernel and adjusting the colors.

I just gave mine a shot. I have a rev 2 processor and with snapchat installed and running the phone lags real bad. If not running snapchat phone is perfect.
If it means anything
Single-Core Score - 1229
Multi-Core Score - 3479

I wonder what the revisions really do? My phone was manufactured in November and has revision 2. It's like they didn't replace one with the other but are just using both unless the revision number is getting lower the newer they are.

i have a rev 2. no performance problems here.
just tryed facebook and snapchat, it doesnt change anything performance wise.
i also play hearthstone and no prob there.
so i think i got a good one
looks like rev3 is not so good
running Chroma Rom with ElementalX Kernel

I have rev2 and my multicore score was 4k, I'm pretty sure Snapchat running poorly is all Marshmallow phones. Snapchat just isn't optimized for 6.0 yet

These are not revisions. Geekbench is reading A57 cores (part 3335) sometimes and A53 cores (part 3331) at other times. I have no idea why it does so but I suppose it has something to do with throttling, not processor revisions.

Droid Turbo PVS bin

What is the PVS bin? It is a known fact that not all semiconductor chips leave the factory equal because of complicated baking process, and for most expensive complex articles like CPU and GPU manufacturers introduced a sorting practice called "binning". Qualcomm also has such scale for their chips, that consist of PVS value range from 1 to 15, to aware Android software how many voltage it should apply to CPU on a certain clock to run error free. The bigger PVS value is, the lesser power required to run CPU stable. So, the story is about energy effectiveness.
Please, share your Droid Turbo PVS bin in a poll.
How to know your bin: use file manager to go to the path /proc/cpu/, and open file msm_acpu_pvs as a text.
PVS bin value is stored as a hexadecimal, so when you see a letter instead of a digit, convert it to decimal like: A=10, B=11, C=12, D=13, E=12, F=15, and vote in the poll above. Thanks! )

LOL. Sorry, added poll lately ) Mine is 6.

Voted. Mines 8.
Does this essentially mean I can undervolt more before the device becomes unstable and reboots, than someone who has a PVS value of let's say 2?

Yes. Probably, your SoC CPU cristal with "8" was in the center of semiconductor wafer, and mine "6" was somewhere closer to the side
The difference in voltage applied not so big, I guess, from 0 to 20mV max in your favor.
As for the "2" CPU, it is tougher, and will be auto driven by higher voltage. Or we set it manually by installing custom kernel with voltage tune support, and try to earn your effectiveness. But then, again, you can start manual control too, tuning voltage down, and Turbo with "2" will suck (

Interesting! Thank you for the explanation! So I guess that's why I'm able to undervolt -70mV without encountering stability issues, where others would get reboots if they did the same.

Mine is 6 and was written as digit

I have a 64gb turbo with 2 :_( :_(
