If its at all possible, and if so, has someone built such an SBC?
Alternatively, is there a practical way to attach external DDRAM to an existing 64-bit SBC, perhaps using the GPIO pins?
I have zero electronics knowledge so forgive my questions if they are stupid.
- deftnerd 9y agoDDRAM requires too much speed to do something through the GPIO or USB... What you could do is use the Tinkerboard S, boot off of a microSD card and use the integrated eMMC storage as a big 16gb swap partition... or just partition the eMMC into an 8gb boot and 8gb swap to give you 10gb usable.
- khedoros1 9y agoIt's definitely possible. Has someone built exactly that? I don't know; there are hundreds of variants of single-board computers, and I'm only familiar with a few. It's not something that you'd build by buying a couple of parts and soldering them to a breadboard. As for attaching memory, GPIO probably gives you a transfer rate on the order of a few MB/s. There are various things like SPI-connected SRAM chips, but those don't provide a lot of memory (think KB, not GB).
