Memory Installation: DIMM0/1/2/3

The nForce 680i SLI/ nForce 680i LT SLI mainboards provide four DIMM (Dual In-Line Memory Modules) sockets which allow you to install 240-pin, unbuffered non-ECC, DDRII 800/ 667/ 533 SDRAMs. They also support Dual Channel Technology and allow you to install a total memory capacity of 8 GB.

Attention

It is recommended that to install memories which are identical specifications (same timing specifications and same DDR II speed) to achieve the best effects. It may cause the failure of power-on or lower memory speed if installing different type, SPD (series presence detects) memories.
