DS918+
Due to a lack of benchmarks with regard to single vs dual channel RAM I decided to perform a quick test using the phoronix-test-suite using the docker container phoronix/pts using the ramspeed test. I have 2 sticks of Synology DDR3L 1866MHz 4GB, performed one run with a single stick and the other with both installed.
Here is the openbenchmarking link Ds918+ 2xddr3 1866 Benchmarks - OpenBenchmarking.org
As you can see there is an improvement which is not unsubstantial considering the low performance of the J3455 CPU. I was hoping for more performance on both single and dual channel but that's what you get for such a low end CPU I guess.

Single channel mean: 7,856 MB/s
Dual channel mean: 10,982 MB/s

I'd be interested to see the performance of lower latency DDR3 1600 modules if anyone has the time or inclination to test. dmidecode output attached for reference.

Nice one! Tnx for this. Considering that 918 model is really common theses days and provides ram update, this will be a usefull info to many.

Would agree on that. Transcode is a pure CPU task with almost no RAM importance.
