PCIe is a pretty complicated protocol based on messages. Using this for RAM would mean the CPU and everything will be required to speak this protocol. Using PCIe for RAM will also have impact on latency, which is undesired.

Speed is not always the only thing.

or perhaps more accurately, bandwidth is not the only goal.

Throughput, latency, cost. Pick 2.
