When mixing RAM, there are no guarantees. In theory, there are no reasons why it should not work OK. But you will certainly lose dual channel bandwidth, and there is still a [strike]change for[/strike] chance of stability issues, and the only way to know is to test.

Maybe. That mobo seems to support Flex dram configuration but the Intel document says both sockets of a channel must be populated. You will lose the dual channel feature.
"Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth operation for real world applications. This mode is used when only a single DIMM is installed or the memory capacities are unequal."

You will, however, get the best performance if you scrap your 2X2GB and get a 2X4GB kit to maintain the dual channel capability.

Thanks for the response guys. I think single channel wouldnt make a big difference. I am tight on budget so I cant ditch the two 2 GB sticks I already have. Should I risk it and buy the 4GB stick I mentioned? will i need to do anything in the bios? Will I need to memtest if I go in successfully? what else should i test.

Just buy the 4GB stick, install it and hope for the best ;) Nothing to configure. Memtest is certainly advised as the first step, but you will also see how it behaves simply by using your PC, especially when gaming. If there are no BSODs, resets, or hangups, even after several days of of usage, you can consider everything to be fine.

I the price is OK you might look at 2X2Gb for your 2 empty slots. That would keep your dual channel capability.
