CPU
Intel® Socket 1155 for Intel® 2nd Generation Core™ i7 Processor/Core™ i5 Processor/Core™ i3 Processor/
Support Enhanced Intel SpeedStep Technology (EIST)
Supports Intel® Turbo Boost Technology 2.0
* The Intel® Turbo Boost technology 2.0 support depends on the CPU types
* Refer towww.asus.com for Intel® CPU support list.

Chipset Intel® P67 Express Chipset
Memory 4 x DIMM, Max. 32 GB, DDR3 2200(O.C.)*/2133(O.C.)*/1866(O.C.)/1600(O.C.)/1333/1066 Non-ECC,Un-buffered Memory
Dual Channel memory architecture
* According to Intel® SPEC, the Max. 32GB memory capacity can be supported with DIMMs of 8GB (or above). ASUS will update QVL once the DIMMs are available on the market.
* Hyper DIMM support is subject to the physical characteristics of individual CPUs. Some hyper DIMMs only support one DIMM per channel. Please refer to Memory QVL for details.
* Due to CPU behavior, DDR3 2200/2000/1800 MHz memory module will run at DDR3 2133/1866/1600 MHz frequency as default.
