1、Replacement Option: This SDRAM board is suitable for Terasic FPGA board and for MisTer FPGA, a good replacement option. 2、Large Memory: Ultra thin (xs d) v2.9 board with 128MB SDR SDRAM memory for cores requiring larger (>512KB) memory (including for Neo Geo cores). 3、Good Performance: Hand welding SDRAM board, allows you to play all for Neo Geo ROM library games, improve game playability, very practical. 4、High Quality Material: The SDRAM board is made of high quality PCB material, with stable and reliable performance and long service life. 5、Professional Design: Each SDRAM board has been fully assembled and tested, tested at 130MHz for more than an hour to ensure your stable use. Item Type: SDRAM Board Material: PCB Product Specifications: This extra slim (XS D) v2.9 motherboard provides 128MB SDR SDRAM memory for cores requiring large (>512KB) memory, including for Neo Geo cores. While for has built in DDR3 RAM, it has high latency and is not suitable for the timings required by retro EDO DRAM. Therefore, if the core requires precise memory timing, the onboard DDR3 cannot be used. You can rest assured that every 128MB SDRAM extra slim (XS D) v2.9 board has been tested at 130 MHz for over an hour using the for Mister MemTest Utility (126MHz is the fastest speed currently required for any core). Each memory module was then soak tested using for Jotego's 48MHz and 96MHz SDRAM test cores. Finally, live testing with for Neo Geo cores, for Acorn Archimedes (Archie) cores, for SEGA MEGA CD cores, and for Neo Geo games, including for Metal Slug 3 and for Bad Neo Geo demos, require 128MB modules to play, these extensive tests to ensure that there are no issues. Features: For Terasic FPGA Board 128MB SDRAM memory module Compatible for Capcom playback systems (CPS-1/1.5 and CPS-2.0) Enjoy all for Neo Geo games Alliance memory AS4C32M16SB-7TIN chip Compatible for MiSTer IO boards Fully assembled and tested 1 x SDRAM Board
