Introduction of Intel H61 Motherboards 
1-1 Features of Motherboard 
The Intel H61 Express chipset based motherboard series are based on Intel H61 
Express chipset technology which supports the innovative Intel LGA 1155 socket 
Intel® Core™ i7, Intel® Core™ i5, Core™ i3. 
The Intel H61 Express chipset based motherboard series comes with an integrated 
DDRIII memory controller for dual channel DDRIII 1066 /DDRIII 1333 MHz system 
memories which are expandable to 8 GB capacity. 
The motherboard provides four serial ATA2 interfaces of 3.0 Gb / s data transfer rate 
for four serial ATA devices. 
Of the H61 Express chipset based motherboards, model MIH61M-DU3 and model 
MIH61M-D series are integrated with gigabit LAN chip providing 10/100/1000Mbps 
data transfer rate while model MIH61M-DS series are integrated with megabit PCI-E 
LAN chip providing 10/100Mbps data transfer rate. 
The H61 Express chipset based motherboard series are embedded 6-channel HD 
CODEC fully compatible with Sound Blaster Pro®standards to offer you home cinema 
quality and absolutely software compatibility. 
The H61 Express chipset based motherboard series offer one PCI-Express2.0 x16 
graphics slot and two PCI Express 2.0 x1 I/O slots to guarantee the rich connectivity 
for the I/O of peripherals. 
Embedded USB controllers as well as capability of expanding to 8 of USB 2.0 
functional ports delivering 480Mb/s bandwidth of rich connectivity and one USB3.0 
port (optional for model MIH61M-DU3) delivering 5Gbp/s bandwidth of rich 
connectivity, these motherboards meet the future USB demands which are also 
equipped with hardware monitor function on system to monitor and protect your 
system and maintain your non-stop business computing. 
Some special features--- OC-CON/ Thunder Protection(optional)/ E.R.P. Standards 
(Optional for model MIH61M-DU3/ MIH61M-DS series) provide extra protection to the 
motherboard to extend product life and ensure system stability. 
1-1-1 Special Features of motherboard 
OC-CON solid capacitors-High-polymer Solid Electrolysis Aluminum Capacitors 
CPU Vcore Input and Output of the motherboard adopts OC-CON solid capacitors to 
make it possible for motherboard to work from 55 degrees Centigrade below zero to 
125 degrees centigrade. OC-CON capacitors possess superior physical 
characteristics to prolong product life ten times than corresponding motherboard 
without capacitors every time working temperature increases 20 degrees. Life of 
product of motherboard with solid capacitors declines only 10% of those without solid 
capacitors as well under same conditions.
