Dual Channel Memory Configuration
The
Due to CPU limitation, if you wish to operate the Dual Channel Technology, follow the guidelines below:
1.Dual Channel mode will not be enabled if only one DDR memory module is installed.
2.To enable Dual Channel mode with 2 memory modules (it is recommended to use memory modules of identical brand, size, chips, and speed), you must install them into DIMM sockets of the same color.
3.To enable Dual Channel mode with 4 memory modules, it is recommended to use memory modules of identical brand, size, chips, and speed.
The following is a Dual Channel Memory configuration table: (DS: Double Side, SS: Single Side)
| DDR1 | DDR2 | DDR3 | DDR4 |
2 memory modules | DS/SS | DS/SS | X | X |
| X | X | DS/SS | DS/SS |
4 memory modules | DS/SS | DS/SS | DS/SS | DS/SS |

If two memory modules are to be used to achieve Dual Channel mode, we recommend installing them in DDR1 and DDR2 DIMM sockets.
All of the memory configurations below will cause system unable to boot. (DS: Double Side, SS: Single Side)
| DDR1 | DDR2 | DDR3 | DDR4 |
1 memory module | X | DS/SS | X | X |
| X | X | X | DS/SS |
2 memory modules | X | DS/SS | DS/SS | X |
| DS/SS | X | X | DS/SS |
| X | DS/SS | X | DS/SS |
3 memory modules | DS/SS | DS/SS | DS/SS | X |
| X | DS/SS | DS/SS | DS/SS |
| DS/SS | X | DS/SS | DS/SS |
| DS/SS | DS/SS | X | DS/SS |
