I have 1 2gb and 1 4gb ram chip.. is this forcing single channel mode?

[Jason H.]

The title says it all.. but also.. unless I have to upgrade.. is there anything to do to boost my memory or force dual channel. Both chips are the same speeds.. just different sizes. My games run like crap and Im starting to think my memory is at fault because everything else is good. Also how do I use my memory multiplier on a Biostar A55ML2 mobo? Thanks

Yes, especially with older mobos, need an equal amount of DRAM in each channel for dual channel mode (up to a 10-15%) increase in performance under dual channel)

is it better to run the two seperate cards to have 6gb of ram or would I get the same performance by removing the 2gb?
