First, where do you get 8GB of RAM that is compatible with a Raspberry Pi 400? Take a Raspberry Pie for sure. The hacker, called Pi-800, shows in their post how they took the memory chip off a Raspberry Pi Compute module 4, then replaced the 200 balls in the ball grid array (BGA) with a judicious use of hot air rework stations and a lot of flux. The chip was then installed on the Raspberry Pi 400s circuit board (after the first two-featiest of 4GB chips). This worked absolutely amazing. Pi-800 lists all of the tools and consumables that they used in their post, and gives some advice if you want to do the same thing, such as using a bit of flux to a single ceramic tweezer tip, where you can pick up the balls of the individual balls. They note that the Samsung and Micron RAM modules being swapped aren’t exactly the same size, so it doesn’t mean you can use the chips casing as a reference point. The test took place using the 64-bit version of the Raspberry Pi, and the full 8GB of RAM was available for the test, and passed memtest. There’s already an update to the Raspberry Pi 402. We certainly want to see that one day.
