Just got the new Pi Zero W from you guys today. Great quick delivery.
Loaded it up with latest Pixel software. when i run the following:-
I get the following:- 700000
On my old pi zero 1.3 with the same command i get 1000000
If i try and change the config.txt file to arm_freq=1000 when i boot the pi zero w it crashes.
Photo of the boot screen.First boot screen.
With arm_freq=950 in the config.txt file i get 0.95Ghz.
But anything over and the system crashes. The chip on board doesn’t run at the stated 1GHz.
So with the command like this “#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800” in the config.txt file the chip runs at 700 Mhz. But on the Pi Zero 1.3 with the default config.txt file it is running @ 1Ghz default.
I’ve done my own testing to confirm this problem- it sheds some light about why we were cursing the slowness of the Zero W yesterday while testing various radio/audio distributions.
I have passed a bug report up the chain- right now it seems like a bug and not a deliberate change. I also certainly wouldn’t take it failing to manually overclock to 1Ghz as an indication that it can’t be overclocked to 1Ghz- I’d guess other factors are at play.
I will update this thread with any response I get back.
Edit: Confirmation that someone is looking into it.
For info, I’ve just checked my new Zero W and it’s running at 700MHz compared to my old Zero running at 1GHz.
/edit - For clarification, I’ve not intentionally overclocked my original Zero, that’s 1GHz out of the box. I’ve also just tried running some intensive tasks to get the CPU up to 100% on the new Zero W to see if the speed varies under load but there’s no change.
Update: Confirmation that they can replicate the issue and are looking into a fix.
Thank you for the update.
Updates will be posted here: Pi Zero W: READ THIS FIRST!
This should be sorted now. A
sudo apt-get update and
sudo apt-get upgrade in the terminal should fix it.
