Everyone loves the Raspberry Pi 400, however may it's higher? One enterprising hacker with a Reddit account thought it may, figuring out the all-in-one pc’s 4GB of RAM as one thing that might be improved, and selected a really hands-on manner of doing it.
Firstly, the place do you get 8GB of RAM that’s appropriate with a Raspberry Pi 400? From one other Raspberry Pi in fact. The hacker, generally known as Pi-800, reveals of their publish how they eliminated the reminiscence chip from a Raspberry Pi Compute Module 4, then changed all 200 balls (every 0.3mm in diameter) of the ball grid array (BGA) with the considered use of a sizzling air rework station and loads of flux. The chip was then positioned into its new house on the Raspberry Pi 400’s circuit board (having eliminated the unique 4GB chip first).
Amazingly, it labored. Pi-800 lists all of the instruments and consumables they used of their publish, and provides some ideas do you have to want to do the identical factor, equivalent to rubbing a tiny little bit of flux on the tip of a single ceramic tweezer tip to can help you choose up the person balls. Additionally they word that the Samsung and Micron RAM modules being swapped should not exactly the identical dimension, that means you'll be able to’t use the place of the chip’s casing as a reference level. They examined their transplant with the 64bit model of the Raspberry Pi OS, and the complete 8GB of RAM was obtainable and handed memtest exams.
With information of a new Raspberry Pi OS with a 64bit model on the horizon, may an official 8GB model of the Raspberry Pi 400 be coming? We would definitely prefer to see that in the future.
