The A7N8X
-X uses the nForce2 400 chipset, which is inherently single-channel. The nF2
Ultra 400 chipset is the dual-channel variant, and is found on the A7N8X "standard," A7N8X Deluxe, and A7N8X-E Deluxe.
If it were any of those last three, it could run dual-channel with either two or three modules installed. The performance boost of dual-channel isn't very significant in most situations, however, so you're only losing maybe 5% of your potential performance. Don't sweat it, just OC the system 5%
