@Mykle1 Don’t worry about it. You provided the information. :) But if you want to do it anyway, do it via SSH instead, you need to have more “screen-space” to fit all the information at the same time. Check my screenshot. The number of columns and rows are much higher. :)

A quick google search reveals that the Pi is mainly manufactured in Wales, UK. However, they are also being made in China, and now Japan. I can’t help but wonder if there is some small difference that would affect performance on those made in the UK and those made elsewhere
-
@Mykle1 Lets see…
Do (in SSH): cat /proc/cpuinfoPaste the result from hardware and revision… :)
Hardware : BCM2835 Revision : a02082I think it’s the “last” revision that is important.
Pi 3 Model B 1GB a02082 (Sony, UK) Pi 3 Model B 1GB a22082 (Embest, China)Mine is from UK it seams. :)
If you cant find it, make it and share it!

Here it is. It appears that mine is also from the UK. How about the other info? Does it match up to yours?

My hardware is also BCM2835 revision a02082 , just like Snille. I have another micro SD I think floating around somewhere in my house, I’ll try and do a clean install of rapsian stretch lite on it tomorrow and use the auto install script on that and see how that goes. Fingers crossed I just got a crappy SD card or something.

How did you make out? I’ve been thinking about this issue since you started the topic. I did quite a bit of googling and there are a number of instances where people had trouble (not with MM) with performance, and heat. In many cases, those people determined that their Pi’s were faulty, after much time, frustration and troubleshooting. In those cases, they had their Pi’s replaced and the problem was solved.
I hope the new SD solves your problem but I have my doubts about that. Please keep me informed and good luck.

@Mykle1
Well I ordered a new pi 3 on Amazon and did a fresh install it’s the same thing all over again. Every time the text changes on magic mirror it maxes out my cpu. And it’s starting to overheat as well and I didn’t even change any overclock settings.Quite infuriating honestly. I don’t know what I’ll try next.

Oh man, that sucks. I’m sorry to hear that. I’m at a lost here. Really, there is no logical reason for that to happen

@Mykle1
My last ditch effort is to try a new SD card. The card it came with is a SanDisk 32gb card and it’s just a plain black card and I have this otherone which is a SanDisk ultra 32gb card so maybe that does something. -
I am certainly rooting for you! I think there was/is a walk-through on preparing the SD card, formatting and such, although I don’t remember where. It’s been a long time.
The best of luck to you. Please keep me posted

@Mykle1
Just to rule out one more variable: the pi 3 should be fine running at 1080p yes? -

Here is my res on an old HP monitor. That’s using the DVI interface. It does not have HDMI.
-
@wtidwell Yeah I don’t use those plain black sd cards I buy the more expensive ones because of the issues.

I looked to see what SD card is in my Pi but all I could come up with is the wrapper it came in. I bought one of those CanaKit’s with everything included. I don’t want to take my mirror down if I don’t have to, sorry.
-
I’m beginning to think it’s the SD card. I did a clean install of Raspian on the SanDisk ultra which is the same class (u1) as the other card which was plain black and it seemed like it was a twinge better but not fantastic. Thanks for your input cowboysdude.
I ordered a SanDisk extreme u3 which will get here tomorrow and try that and report back in. Don’t take your mirror down haha

I hope that’s it. Then we can all laugh about it. Keep me posted.
Just in case:
https://www.raspberrypi.org/documentation/installation/installing-images/And:
HOW TO FORMAT AN SD CARD AS FAT Note: If you're formatting an SD (or micro SD) card that has a capacity over 32GB (i.e. 64GB and above), then see the separate SDXC formatting instructions. WINDOWS For Windows users we recommend formatting your SD card using the SD Association's Formatting Tool, which can be downloaded from sdcard.org. You will need to set "FORMAT SIZE ADJUSTMENT" option to "ON" in the "Options" menu to ensure that the entire SD card volume is formatted, and not just a single partition. The updated size will be shown after the format is complete. MAC OS The SD Association's Formatting Tool is also available for Mac users, although the default OS X Disk Utility is also capable of formatting the entire disk. To do this, select the SD card volume and choose Erase with MS-DOS format. LINUX For Linux users we recommend gparted (or the command line version parted). Norman Dunbar has written up instructions for Linux users. -
Ok, this is the kit I bought back in January. I checked my amazon.com history.

That is also where I installed my Raspbian Jessie from. You can install it from NOOBS
