Chipset

Intel® P67(B3) Express Chipset

Memory

4 x DIMM, Max. 32 GB, DDR3 2200(O.C.)*/2133(O.C.)/1866(O.C.)/1600/1333/1066 Non-ECC,Un-buffered Memory
Dual Channel memory architecture
Supports Intel® Extreme Memory Profile (XMP)
* 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.
* Please refer to www.asus.com or user manual for Memory QVL.

Expansion Slots

2 x PCIe 2.0 x16 (single at x16 or dual at x8/x8 mode)
1 x PCIe 2.0 x16 * [Black] (max. at x4 mode, compatible with PCIe x1 and x4 devices)
2 x PCIe 2.0 x1
2 x PCI
*The PCIe x16_3 slot shares bandwidth with PCIe x1_1 slot, PCIe x1_2 slot, USB3_34 and ESATA12. The PCIe x16_3 runs at x1 mode by default for system resource optimization.(PCIe x1_2 will be disabled.)
