This Extra Slim (XS-D) v2.5 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.

All my Extra Slim (XS-D) SDRAM boards have been checked under a microscope to ensure no solder bridges are present, then each 128MB SDRAM board is cleaned in an ultrasonic bath to remove flux residue. Every one of my boards uses the high quality Alliance memory paired with KEMET branded capacitors on each board.

You can be confident knowing each 128MB SDRAM Extra Slim (XS-D) v2.5 board has been tested for over an hour at 130 MHz (126 MHz is the fastest any current core needs). I have also tested each with the Neo Geo console 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 this ensures no issues are present.

    Excellent very high quality products, am a returning customer. Nathan is a pleasure to do business with and goes beyond my expectations of a seller. Item arrived well packaged, and was an instant upgrade. 128mb is what you need for Neo-Geo and many more cores for the MiSTerFPGA

    Really well made, tiny little board even smaller than my 32MB, works great and Nathan is a nice chap he even offered to pop it round my house as he was in the area, what a guy!

    I got it faster than expected and everything is working like a charm. I thought it might be best to order while UK is still in the EU 🙂 I highly recommend this purchase if you want to get the most out of your MiSTer.

    The memory board worked great. I tested in the memory test and it worked for 6 hours straight with no errors at 130Mhz. Nat is very responsive with questions about the order. It was a pleasure buying this memory board from you. Thank you.
