Gigabyte GA-SINXP1394 User Manual page 17

GA-SINXP1394 supports the Dual Channel Technology. After operating the Dual Channel Technology,
the bandwidth of Memory Bus will add double up to 5.4GB/s.
GA-SINXP1394 includes 4 DIM M sockets, and each Channel has two DIMM sockets as following:
Channel A : DIMM 1, DIMM 2
Channel B : DIMM 3, DIMM 4
If you want to operate the Dual Channel Technology, please note the following explanations due
to the limitation of
1. Only one DDR memory m odule is installed: The Dual Channel Technology can't operate
when only one DDR memory module is installed.
2. Two DDR memory modules are installed (the same memory size and type): The Dual
Channel Technology will operate when two memory modules are inserted individually into
Channel A and B. If you install two memory modules in the same channel, the Dual Channel
Technology will not operate. Additionally, you can boot the system only when one of the
memory m odules is inserted into Channel A or Channel B. On the other hand, the memory
module must be inserted into any sockets.
3. Three DDR memory modules are installed: If you install three memory modules at the same
tim e, the Dual Channel Technology will operate only when those modules have the same
memory size and type.
4. Four DDR memory modules are installed: If you install four memory modules at the same
tim e, the Dual Channel Technology will operate only when those modules have the same
memory size and type.
We'll strongly recommend our user to slot into two DDR memory modules into the DIMMs with the same
color in order for Dual Channel Technology to work.
The following tables include all memory-installed combination types:
(Please note that those types not in the tables will not boot up.)
