Was it this one viewtopic.php?p=1701237 ? Not sure it's the same.
Note also that if you use the quite inexpensive RPF PSU, the Pi4B never had a power issue in the first place. That "issue" was more of a tempest in a teapot than anything else.myystiquee wrote: ↑Fri Jul 24, 2020 8:04 pmThank you everyone for your reply.
For jamesh : No, I'm not spam, don't worry.
For pidd : Sorry, I didn't mean for my message to sound like an attack on Raspberry. I'm aware that many companies have bugs with the distribution of a new product.
In this case, pi 4 has been reviewed and it's cool and that's all I wanted to know. I'm glad to know that many Raspberry users are happy and I hope to become one too!
Examples of the sort of power supplies that have this issue are Apple iPad and iPhone chargers. Quite a few people already have those and would probably expect them to work on a Pi with USB-C power input.cleverca22 wrote: ↑Sat Jul 25, 2020 4:10 amone of the other threads also mentioned, that only a usb-c PSU that costs more then a pi4, is smart enough to notice the problem the pi4 originally had
so i feel like most users wont be having such a PSU just laying around, and likely would never notice the problem
The Pi 4B boards now being manufactured have been updated so the USB-C issue no longer exists on those. But some older boards may still be in some supply chains and can be encountered outside those.
Inefficient. RPiOS32 uses LPAE and has to page stuff in and out all the time.
That's WIndows. Linux on the other hand (LPAE not PAE) does rather better by the looks of it and can use all all of the 8GB.

That is all I know about 64-bit operating systems on ARM computers. The "Raspberry Pi people" were using the the 64-bit version of the Raspbian operating system much longer than myself. I didn't use the 64-bit version of Raspbian for numerous reasons I will not mention at this moment.
I found this article on the Microsoft website website that explains Physical Address Extensions for X86 based computers:

I have a link to a topic on Tom's Hardware Forum about 8GB of RAM on a Windows 32-bit PC:
Can you run 8gb ram in 32 bit windows - Tom's Hardware Forum

If you read the conversation, you will see a user will say "do not bother installing anymore RAM" to a 32-bit computer. If the computer has 8 GB of RAM, Windows 32-bit will only see 4 GB of RAM. This means using a 64-bit operating with 8GB of RAM is unavoidable. The Raspberry Pi 4 computer uses a 64-bit processor.
Moreso of ARM than Intel, actually. aarch64 is fundamentally different to aarch32 and when you're in one mode, instructions in the other will be misinterpreted or fault; you can't interleave them (although the 32b registers are available in aarch64 mode). With amd64, (almost) all the IA32 instructions are still present and functional; the 64b stuff is an extension.
