Even if HDD/SSD makers use 1000, while customers often unknowingly expect 1024 and complain that their new 1TB drive only has 931.32 GiB.
(listing specs on a product however rarely does this since people genereally don’t care about such trivialities. (unless it is one of the exceptionally few cases where it might be the thing specified, but here any serious author should use “ki” instead. I were more pointing out the fact that one shouldn’t in general confuse the prefix “k” for 1024. Posted in Raspberry Pi Tagged bga, memory, raspberry pi, Raspberry Pi 800 Post navigationīrightBlueJim I hope you noticed how even my own comment already states that it is rare and generally only applicable in a handful of areas. It’s certainly not the first BGA memory swap we’ve brought you.
Perhaps we’ll wait for that, but should you be impatient then at least it’s possible to roll your own. The result is an 8 GB all-in-one Pi, and it’s honestly not beyond the realms of possibility that an official version of this mod could be a future Raspberry Pi product. A soldering task we’d hesitate to take on ourselves, so we’re impressed. This is normally done with a template of carefully aligned holes to line up balls of solder in a stream of hot air, but lacking the template in this case the job was done by hand, laboriously ball by ball.
A ball-grid-array chip has a grid of small balls of solder on its underside that make the contacts, and these melt when it is soldered so require replacement before reworking. What takes it beyond the norm though is the reballing process. When the Pi 4 and Compute Module 4 have double that figure, surely the Pi 400 could catch up! A reddit user called rose to the challenge by replacing the 4 GB chip from the Pi 400 with the 8 GB chip from a Pi Compute Module, resulting in the so-called Pi 800, a working 8 GB all-in-one Pi.Īs a piece of work it’s a deceptively straightforward yet extremely fiddly piece of soldering that requires a steady hand for even the most skilled of solderers. The all-in-one Raspberry Pi 400 computer is a capable device, but those seeking its maximum power may be disappointed by its 4 GB of memory.
