This is not the case for Intel platforms (even as far back as LGA 775, possibly earlier), though I am unclear on AM2/AM2+.

Intel setups should default to flex memory/dual-channel asymmetric mode.

turns out this is the case, it reverts to asymmetric mode which is still 128Bit but not as effective as true dual channel

thanks for the help smile.gif
