This Extra Slim (XS-D) v2.9 board provides 128MB of SDR SDRAM memory for cores requiring a large (>512KB) of memory including the Neo Geo core. 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.
You can be confident knowing each 128MB SDRAM Extra Slim (XS-D) v2.9 board has been tested for over an hour at 130 MHz with the Mister MemTest Utility (126MHz is the fastest any current core needs). Also each memory module is then soak tested with Jotego's 48MHz and 96MHz SDRAM test cores. Finally live tests are performed with the Neo Geo core, Acorn Archimedes (Archie) core, Game Boy Advance core, SEGA MEGA CD core and in Neo Geo games including Metal Slug 3 and the Bad Apple Neo Geo demo which require a 128MB module to play, these extensive tests ensures no issues are present.

Extra slim v2.2 board (SDRAM XS v2.2)
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 board is tested at 150Mhz for at least half an hour. Every one of my boards uses the higher quality Winbond chips, high quality KEMET branded capacitors are used on each board.
You can be confident knowing each Extra Slim (XS) v2.2 SDRAM board has been tested for over half an hour at 150MHz using the SDRAM Board Test Service Core . I also test each with a number of console cores in games to ensure no issues are present。
