Affected person Hacker Upgrades a Raspberry Pi 400 With 8GB of RAM

It is attainable to purchase a Raspberry Pi 4 with 8GB of RAM, however the Raspberry Pi 400 keyboard solely ships with 4GB of RAM. Nonetheless, it may be upgraded manually with a number of arduous work and persistence.

As Tom's Hardware reports, a Reddit consumer who goes by the title Pi800 really wanted a Pi 400 with 8GB of RAM. You'll be able to't buy a RAM module that matches the customized Pi board, however Pi800 realized the Rapsberry Pi Compute Module has "virtually equivalent" RAM circuitry in comparison with the Pi400 and it is attainable to purchase one with 8GB of RAM hooked up.

Pi800 then took the plain step of fastidiously eradicating the 8GB chip from the Comnputer Module, which required a number of warmth because of the lead-free solder holding it in place. Because the module hooked up to the board utilizing a ball grid array (BGA), Pi800 wanted to "reball" the chip, which was achieved by hand somewhat than utilizing a BGA stencil. In complete, 200 balls had been melted on to the chip in preparation for attachment to the Pi400.

The outdated 4GB RAM module was eliminated and the PCB cleaned earlier than soldering the 8GB module in place and hoping the transplant would work. Positive sufficient, the modified Pi 400 booted and acknowledged 8GB of RAM was out there. A RAM check then confirmed the RAM labored as anticipated and the mod was full.

Contemplating this was only a straight chip swap, it is shocking a Pi 400 hasn't been supplied with 8GB of RAM as an choice. Maybe will probably be in future, however with chip supplies and prices the way in which they're in the intervening time, it might not occur for fairly a while.
