Dual Channel
Aspire T670/Acer Power F3 support the Dual Channel Technology. After operating the dual channel
technology, the bandwidth of memory bus will add double up to 4GB/s.
Aspire T670/AcerPower FE inculde 4 DIMM slots, and each channel has two DIMM sockets as following:
T
Channel A : DDR1, DDR3
T
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.
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:
Memory Number Description
1 Only one DDR memory module 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.
3 Three DDR memory modules are
installed ? Pleae note that the Dual Channel Technology will not operate
when three DDR memory modules are installed; part of them will
not be detected.
4 Four DDR memory modules are
installed ? If you install four memory modules at the same time, the Dual
Channel Technology will operate only when those modules have
the same size and type.
