Does External RAM Exist?

[Reg88]

I have an early 2015 13" MBP with 8GB RAM and it really could use a RAM bump. Unfortunately this machine is not upgradeable. Is there any way to attach an external drive and use it as some type of overflow RAM?

Thanks!

I don't think any interface on the system would have the speed needed to do so?...IIRC doesn't the DDR3 RAM in your machine peak at speeds of like 12-14 GB/s?

No, its technically impossible

Using the internal SSD would likely be faster than having external RAM, so the idea would be pointless.

This great idea is exactly what any computer is already doing since the existing of modern computers;-) at least 25 years...
It swaps data to the internal storage/SSD when ur RAM is full. see activity monitor "swap used". But RAM is about 50-100 times faster...
