Last week the Raspberry Pi foundation announced that they’d started shipping new units with 512mb ram chips instead of the previously supplied 256mb ones. Sounded like the perfect excuse to get hold of a second Pi – I ordered one on Monday and to my surprise it arrived yesterday, just a five day turnaround (thank you Element14/Farnell).
I wanted to use my existing SD card (SanDisk 8GB x10) as it has a fair bit of stuff on it (including this website) so I needed to get Raspian to notice the extra RAM. I downloaded the updated firmware files into the Pi’s /boot directory and added gpu_mem=256 to /boot/config.txt – this gives me a 50:50 split, 256mb for the GUI/GPU and 256mb for the CPU. Rebooted and it works a treat, seems a wee bit snappier too.
