If you only need DDR3-like throughput you can keep a minimum of RAM for booting and caching, and set up swap on an Intel Optane drive: they're widely available and cheap (at least cheaper than RAM) on the second-hand market.

(For read only workloads (no writes or only very rare writes) any ordinary SSD would suffice; the point of resorting to Optane is its unique wearout resistance.)
