ram single or dual

Hi all i did make a benchmark where is told me with a red line ensure that a dual+ channel XMP BIOS profile is enabled. here is the link http://www.userbenchmark.com/UserRun/3838925 with my spec but dual what do it mean with that in CPU-Z is say its single channel ?

Channel is in reference to what slots your sticks of ram are in on the mobo. if you have one stick, make sure it is in the left-most slot. if you have two sticks, make sure they are in the first and the third slots from left to right (you may need to check mobo manual to make sure this is the correct configuration).

FYI, reading a single DIMM has certain performance limits. Reading two DIMMs, one at a time, has the same limits. Storing and reading two DIMMs simultaneously without accessing the same data at the same time could in theory double performance if it were possible to access the DIMMs with two threads. However, if the two DIMMs interleaved individual data bytes, and each were accessed at the same time, then you would double data performance in a single thread. Each DIMM would have 4-bits of an 8-bit byte. There is a similar scaling for four DIMMs...quad channel interleaving 2-bits from each DIMM to access 8-bit bytes from a single thread.

Your BIOS/UEFI settings have to be told to use interleaved data (single, dual, or quad channel). Non-interleaved does not require matching DIMMs. Once multi-channel is used all DIMMs involved must be exact matches.
