Acer L310 Dual Channel Technology DS Double Side, SS Single Side, Memory Number Description

Dual Channel

VT x800 series support the Dual Channel Technology. After operating the dual channel technology, the bandwidth of memory bus will add double up to 4GB/s.

The mainboard inculdes 4 DIMM slots, and each channel has two DIMM sockets as following: Channel A : DDR1, DDR3

Channel B : DDR2 , DDR4

If you want to operate the Dual Channel Technology, please note the following explanations due to the limitation of Intel chipset specifications.

	Memory Number	Description
1	Only one DDR memory module is	The Dual Channel Technology can’t operate when only
	installed ?	one DDR memory module is installed.
2	Two DDR memory modules are	The Dual Channel Technology will operate when two
	installed ( the same memory size	memory modules are inserted individually into Channel A
	and type) ?	and B. If you install two memory modules in the same
		channel, the Dual Channel Technology will not operate.
3	Three DDR memory modules are	Pleae note that the Dual Channel Technology will not
	installed ?	operate when three DDR memory modules are installed;
		part of them will not be detected.
4	Four DDR memory modules are	If you install four memory modules at the same time, the
	installed ?	Dual Channel Technology will operate only when those
		modules have the same size and type.

NOTE: We strongly recommend user to slot 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:
