Intel Core i7 2600K and Core i5 2500K Review


Closer Look:

The DP67BG (Burrage) is the board being marketed as the Intel board for the "Power User" and comes with the full hardcore feature set. This board is built using the Intel P67 chipset that offers a one-chip solution to reduce power consumption and increase the available space on the board for more efficient routing. Intel Hyper-Threading and Turbo Boost 2.0 Technology are supported. You get DDR3 1600+/1333/1066MHz memory support with up to 32GB of memory in a dual-channel configuration, onboard POST decoder, CHiL voltage controller, USB 3.0, SATA 6 GB/s support, SLI and CrossfireX multi-GPU support, and more. Intel made sure to throw in all the bells and whistles to make sure this board performs. From the front, you get an idea that this full size ATX form factor board means business. The large heat sinks on the VRM circuit and PCH should keep these components cool under load. The rear is featureless with the exception of the back of the CPU socket retention mechanism. Another feature of the DP67BG is that it meets worldwide lead-free requirements, so you can be assured you wont be poisoning the little ones in your household. If you remember the DX58SO used to test the Core i7 965 and 920, when they were released in November 2008, the Skull at the bottom right of the PCB should be a familiar sight and lights up with HDD activity.


















I/O connectivity is pretty standard for a motherboard in the gaming/enthusiast market with a notable exception that Intel boards are really the only ones without a PS/2 connection for the mouse/keyboard. Many people still have a PS/2 keyboard, while many more have adopted a USB mouse. This is one of those things to think about when making your purchase decisions. Starting from the left is an eSATA port, a single 1394a Firewire port with another available from an internal header, eight of the fourteen USB 2.0 ports are available on the back with six more available through internal headers, a Back to BIOS switch that allows you to recover the BIOS after a failed overclock, an Ethernet port, two USB 3.0 Super Speed ports (Blue), the five analog sound ports, and the Optical SPDI/F port used in this ten-channel design. Expansion slots include two 16x PCIe slots that run at either 16x when one is populated and 8x/8x when both are populated in either a CrossfireX or SLI configuration, as well as three 1x PCIe 2.0 slots and a pair of PCI slots.



Along the bottom is where you find the additional connectivity for the DP67BG. In front of the bottom PCIe 16x slot is the front panel audio connection. On the bottom edge is an auxiliary fan header, SPDI/F output, and Diagnostic LEDs to help diagnose a no POST condition and to tell you what parts have initialized. Next is the front panel connection for the Power and Reset switches, as well as the HDD and Power LEDs. There there is the 1394a Firewire header and the three USB 2.0 headers that add an additional six USB 2.0 ports to bring the total of available ports to fourteen.



This board is equipped with a pair of SATA 6GB/s ports and four SATA 3GB/s ports that support RAID 0,1,5,10 using Intel Rapid Storage Technology. All these ports are 90 degree ports, eliminating any issues with discrete video card interference. Before the SATA ports are the Infrared receiver and transmitter. Behind this area is the Skull design that includes LEDs that light up with HDD activity and the Clear CMOS jumper (useful if the Back to BIOS switch does not help). Further up the right side of the board is another fan header, the 24-pin ATX power connection, and the onboard start and reset buttons - an added feature that is welcomed on this board. Add in the debug LED and you have a board that is showing Intel's commitment to the enthusiast segment of the market. Combined with the LEDs at the bottom of the board, you should have no problem diagnosing a no POST condition.


There is not much across the top of the PCB, but there are a couple of fan headers and the 8-pin auxiliary power supply connection for CPU power.



The CPU socket is surrounded by ferrite chokes and capacitors for the power regulation circuit for the Socket 1155 Core i7 and Core i5 processors. There are a total of four DIMM slots that support up to 32GB of DDR3 memory at speeds of 1600+/1333/1066MHz in a dual-channel configuration. This is similar to the socket 1156-based systems in terms of the layout.



The power circuits for the CPU are covered in large heat sinks to provide adequate cooling to the power circuit under load. Both of these heat sinks will benefit from airflow through the chassis or from a low profile heat sink that blows air directly over them. The PCH is covered in a single low profile heat sink and will most likely spend time under a discrete graphics card where it should see some airflow through the fan intake.



This board will be used to test the performance of the second generation Core i7 2600K processor to see what kind of performance it delivers, with the exception of the integrated graphics testing, which will be completed on the DH67BL.
