Some food for thought: RAM timings are practically the same in absolute time regardless of RAM speed. At least as far as human time scales are concerned

Though let's play with this. What if we take bandwidth + latency into account and do a 4 KiB transfer? i.e., a worst case scenario. And let's use the Adata XPG Z1's metric.

 

DDR4-4000: 4096 bytes * 0.250ns/byte + 17.9ns latency = 1.0419 us

DDR4-3466: 4096 bytes * 0.288ns/byte + 16.3ns latency = 1.198 us

 

So the DDR4-4000 setting is still faster overall.

    The bandwidth may not actually be correct, since the speed is really transfers/sec. But eh, it doesn't matter in the end what is being transferred.
