Talking Single vs Dual channel memory

I just run benchmarks with single channel vs dual channel memory. Here they are.
Xeon E3-1225 v3, 3.20 GHz, LL Test on a 36M exponent.

Single channel:
4 workers: 6.5 ms/iter
3 workers: 6.4 ms/iter
2 workers: 6.8 ms/iter
1 worker: 10.0 ms/iter

Dual channel:
4 workers: 3.2 ms/iter
3 workers: 3.5 ms/iter
2 workers: 5.0 ms/iter
1 worker: 9.2 ms/iter
