depends on the chipset, if its intel it will run in Flex mode. here are the rules (basically) I would need to know your exact chipset, or even better you find out, go to intel.com desktops chipset select your chipset and look/read the data sheet for your memory controller hub. Its actually fairly smart and will do its best to run what memory it can in dual channel. Dual Channel Interleaved is the fastest.

10.2.1.1 Rules for Populating DIMM Slots
In all modes, the frequency of system memory will be the lowest frequency of all of
the DIMMs in the system, as determined through the SPD registers on the DIMMs.

In Single Channel mode, any DIMM slot within the channel may be populated in any
order. Either channel may be used. To save power, do not populate the unused
channel.

In Dual Channel Asymmetric mode, any DIMM slot may be populated in any order.

In Dual Channel Interleaved mode, any DIMM slot may be populated in any order, but
the total memory in each channel must be the same.

In Flex memory mode, any DIMM slot may be populated in any order per channel, but each channel must have at least 1 DIMM. The matching amount of memory per channel will be run in Dual channel interleaved mode and the remaining unmatched memory will run in Asymmetric mode.
