Considering that dual channel mode is supposed to double the bandwidth available,
we were expecting to see bigger drop in performance when going back to single
channel mode. Instead the difference is 5% at most.

Doom 3 seems to be considerably affected by having only 256MB of memory. 512MB
seems to be the bare minimum.
