This Extra Slim (XS) v2.2 board provides 32MB of SDR SDRAM memory for cores requiring a large (>512KB) of memory. Although the DE10-Nano has built in DDR3 RAM, it has a high latency and is not suitable for the timings required of retro EDO DRAM. So if a core requires precise memory timings, then the onboard DDR3 cannot be used. All my Extra Slim (XS) SDRAM boards have been checked under a microscope to ensure no solder bridges are present, then each MiSTer SDRAM board is cleaned in an ultrasonic bath to remove flux residue.
