Note:
1. The reference value above is for Core i7 2600K D2 ver. Processor.
2. The condition is based on air cooling.
3. Increasing voltage may raise the success rate of overclocking as the risk of damage
the CPU; thus,we suggest use the special design CPU cooler set to prevent the CPU
from overheating.
4. Below voltage value would cause the damage of component while under air cooling.
• CPU Voltage:1.6V
• CPU I0 Voltage:1.5V
• DRAM Voltage:1.9V
We suggest disable some item in BIOS,such as Green Power Phase Contral and
OverSpeed Protection.

BUILD UP HIGHER BANDWIDTH
WITH SATA 6Gb/s
Considering user’s requirement for massive data transmission, high data
bandwidth has become an essential for the development of motherboard,
and SATA 6Gb/s is probably the best solution for insufficient bandwidth at
the present time.P67A-GD55 (B3) contains four SATA 6Gb/s ports that maxi-
mize data transmission bandwidth through the Intel P67 and Marvell SATA
6Gb/s controller chip. In terms of data transmission cable, SATA 6Gb/s hard
disk and the previous generation, SATA 3Gb/s, share the same data cable, as
well as the SATA power cable.
SATA Performance Comparison
SATA 3Gb/s SATA 6Gb/s
To ensure the hard disk transmission rate is optimized, it is strongly recom-
mended to use SATA 6Gb/s SSD. Even create a RAID 0 disk system with two
hard disks that support SATA 6Gb/s.
There are two white SATA III (6Gbps) connectors on the mainbaord.
