Part two: A Closer Look

I have always liked black PCBs, they really let your components stand out. This version has white PCI slots, which the rep tells me is most likely going to change as they are discussing a brighter hue, probably neon green. I also noticed the passive cooling for the northbridge chip. XFX seem to have chosen to go with a no-noise solution, rather than the more common active cooling for the northbridge. This situation, paired with the two phase power scheme leaves me to question the overclocking potential of this board.

There are 6 PCI slots and an 8X AGP port. One thing that threw me off was the total lack of a locking mechanism for the AGP card; especially from a company that manufactures a very nice line of graphics cards. One would think that the expectation for tinkering and full-sized graphics cards would be in the plans for 'The ultimate graphics mainboard'

The CPU socket is situated 90 Degrees from normal, making installation of a HSF as burly as the Volcano7+ a daunting task. There is no way to get this thing on or off once the motherboard is situated in a case unless it has a removable tray. My ThermoEngine was a little better fit, but still had to be installed with the board on the bench. The row of capacitors and northbridge heatsink make the area a bit snug for maneuvering a screwdriver into the locking clip.

While checking the seat of the HSF, I noticed this transistor sticking up in a curious place. If one is not careful, they might just find themselves with an RMA no sooner than installing the HSF.

The three DIMM sockets support up to 3GB of PC2700 RAM @ 333MHz.

To my surprise there are only two fan headers on the motherboard; one for the HSF and another at the bottom edge below PCI 6, much too far for the PSU fan to reach. Any extra fans (including the PSU or northbrige cooling, should you upgrade) will have to use 4 pin MOLEX connectors. I guess two phase power leaves little room for 'extras' like cooling. I prefer to use 3 pin headers for my fans so I can keep an eye on them with Motherboard Monitor, but this may not be important to the average Joe.

The ATX connector is in a fairly common place and should be accessible by most PSU cabling. A little low for some, but most modern PSUs are designed with full size towers in mind so there should be no problem.

A closer look at the Northbridge chip reveals:

1) The lack of thermal paste on this sample (which, I am told is a mistake and there should have been some) and…

2) ...That this really is a KT400 (The southbridge is the VT8235)

The I/O panel on the rear of the board has a full roll call of connectors. From 5.1 surround, 2 USB 2.0 ports and onboard LAN, I can't think of anything that was omitted. There should be no surprises when you go to connect most peripherals.

Let's get this thing installed and booted up....
