Processors
This motherboard supports the Intel® 3rd/2nd generation Core™ i7/i5/i3/Pentium®/Celeron®
processors in the LGA1155 package, with iGPU, memory, and PCI Express controllers
integrated to support onboard graphics out with dedicated chipsets, 2-channel (2 DIMMs)
DDR3 memory, and 16 PCI Express 3.0/2.0 lanes. This provides great graphics performance.
Intel® 3rd/2nd generation Core™ i7/i5/i3/Pentium®/Celeron® processors are among the
most powerful and energy efcient CPUs in the world.
Intel® Z77 Express Chipset
The Intel® Z77 Express Chipset is a single-chipset designed to support the 1155 socket
Intel® 3rd/2nd generation Core™ i7/i5/ i3/Pentium®/Celeron® processors. It provides
improved performance by utilizing serial point-to-point links, allowing increased bandwidth
and stability. Additionally, Z77 chipset provides 4 USB 3.0 ports for 10 times faster data
retrieval speed. Moreover, Intel® Z77 Express Chipset can also enable iGPU function, letting
users enjoy the latest Intel® integrated graphic performance.
PCI Express
®
3.0
PCI Express® 3.0 (PCIe 3.0) is the latest PCI Express bus standard with improved encoding
schemes that provide twice the performance of the current PCIe 2.0. The total bandwidth
for a x16 link reaches a maximum of 32Gb/s, double the 16Gb/s of PCIe 2.0 (in x16 mode).
PCIe 3.0 provides users with unprecedented data speeds, combined with the convenience
and seamless transition offered by complete backward compatibility with PCIe 1.0 and PCIe
2.0 devices. PCIe 3.0 will become a must-have feature for users who wish to improve and
optimize graphic performance, as well as have the latest technology available to them.
* PCI 3.0 speed is supported by Intel® 3rd generation Core™ processors.
Dual-Channel DDR3 2400 (O.C.) / 2200 (O.C.) / 2133 (O.C.) / 1866 (O.C.) / 1600 /
1333 / 1066 MHz Support
The motherboard supports the dual-channel DDR3 memory that features data transfer rates
of DDR3 2400(O.C.) / 2200(O.C.) / 2133(O.C.) / 1866(O.C.) / 1600 / 1333 / 1066 MHz to
boost the system’s performance, and to meet the higher bandwidth requirements of 3D
graphics, multimedia, and Internet applications.
* Due to Intel
®
2nd generation processor’s behavior, DDR3 2200 (and higher), and DDR3 2000/1800 MHz memory
modules run at default rates of DDR3 2133/1866/1600 MHz.
