..:: D875PBZ “Bonanza” Layout: Socket Area ::..

Overall, the design of the Intel D875PBZ is impressive, especially considering the neat layout and orientation of all of the onboard chips, connectors, and other devices. The D875PBZ utilizes a stylish black PCB much like what we saw with the D845PEBT2, certainly something a modding fan might take notice of. The main thing that will jump out at many of you is the shear size of the 82875P Northbridge heatsink unit. This is one massive piece of Aluminum and it does a very nice job of keeping the 82875P chip running as cool as possible. My personal favorite item dealing with the layout of the D875PBZ would have to be the location of the main 12V ATX power connector. I certainly consider this to be in an ideal position for proper system airflow. That’s a quick overview of the more important aspects we’ll be discussing, now let’s get on with a more detailed look at the D875PBZ.

The D875PBZ comes along with the usual black heatsink retention system that is utilized for the Pentium 4 processors. The processor socket is oriented lengthwise from north to south and roughly reaches to the top edge of the PCB with only a few millimeters to spare. As you can see, we already have our 800MHz FSB Pentium 4 mounted in the processor socket for added color…ok maybe not. The area to the right of the processor socket is very clean and clear of any large devices. Here we also come across the location of the white, three-pin CPU fan connector. This connector is located in the open and will be easily accessible in all situations, unlike what we saw with the D845PEBT2. Even with DIMM’s filled, there won’t be any problems considering the amount of space between the CPU retention mechanism and the first set of DIMM’s.

Along the left hand side of the processor socket area, we come across the usual mass of electrical components and capacitors. The components are very neatly organized in a linear fashion, and add a little contrast to the motherboard as they are of course yellow. There are eight small MOSFET’s located in a slightly staggered array in this area, and we can also see that the D875PBZ utilizes a two-phase power solution because of the dual inductors. If we take a look towards the bottom of the capacitors and MOSFET’s, we can also see the four-pin core voltage power connector. I don’t particularly care for it to be so low on the board, although given the fact that the cabling for this connector is virtually null and in most cases can easily be routed throughout the case, it isn’t a big issue. If we take a look towards the top edge of the board, we’ll come across the second of four white, three-pin power connectors. This connector can be used for the fan that should be placed in the rear of the chassis for airflow exhaust. Although this connector is placed high on the board, the relative cleanliness of the area should allow fairly easy access to it whenever need be.
