In typical DFI LANParty UT fashion, the amount of BIOS tweaks available to fine tune the performance of this board is incredible. Our chart does not do justice to all of the BIOS settings available but rest assured the performance enthusiast will think they are in a winter wonderland. On the flip side, the sheer number of options can be overwhelming for some, but we found the majority of auto settings provided a very good level of base performance. This held true in most areas except on the memory side where it was best to switch to manual settings and change the tCAS, tRCD, tRP, tRAS, and the command timing rates at a bare minimum. The performance results generated from this board are directly attributable to your choice of memory and capability to fine tune each individual setting to extract the best performance possible. We will delve into this subject in our full review along with detailed BIOS screenshots of our final setup choices for each memory speed. That said, the best attribute of this chipset and BIOS design is the almost infinite flexibility you have in separately controlling your FSB and memory speeds.

The board layout that DFI settled on is very good for the high-end enthusiast who utilizes alternative cooling solutions. The CPU area is clutter free due to the use of a six phase digital PWM power delivery system and offset with the intention that water or phase based cooling solutions will be used. We will include pictures of our case installation and that of several aftermarket heatsinks we utilized during testing shortly. In smaller ATX cases, most large air coolers such as the Scythe Infinity will have trouble fitting. Our Tuniq 120 had the best clearance in the midrange cases of all the large air coolers. The RD600 is cooled by a large passive heatsink that was well suited for the job until we started overclocking the FSB past 450. Due to the Northbridge voltage required to reach the maximum 511 FSB, the stock heatsink will require airflow over it. We would have preferred to replace the heatsink during this type of overclocking but DFI utilized the four hook attachment system that left us very little choice other than to direct airflow over the stock unit with an extra fan at this time.

The PCI Express and PCI slot arrangements are designed with multiple graphics card operation in mind but this layout will mean the removal of your primary graphics card if you need to switch memory. The board includes six fan headers, three of which can be controlled in the BIOS or by the included ITE Guardian utility. Other nice touches include the onboard power and reset buttons along with a diagnostic LED display. You can clear the CMOS by using the jumper or by simultaneously holding down the reset and power buttons for four seconds. If the board is in a case this same procedure can be completed by holding down the front panel reset and power buttons. DFI also includes the new AMD System Manager that allows you to change voltages, memory, and FSB values within Windows.

The Karajan audio module is plugged into a socket located on the motherboard near the I/O panel and features the Realtek ALC885 which we found to offer very good sound, but EAX compatibility is still needs improvement. The board also features two Marvell PCI-E based Gigabit Ethernet controllers that can be teamed together through a new Marvell software utility. We are still testing this capability but overall the Marvell controllers provide good throughput and CPU utilization numbers. Also included are four SATA 3Gb/s ports via the SB600, four additional SATA 3Gb/s ports from the PCI based Promise PDC40719 controller, a single Ultra ATA 133 IDE port supporting two IDE devices, FireWire 400 support from the VIA VT6307, three PCI slots, and three PCI Express x16 slots that are configured dual x8 (x16 for single card in the first slot) and single x2 electrically.

The third x16 slot is designed for the upcoming ATI/AMD physics capability. This slot can be jumpered for PCI Express card operation and we are testing it currently. Unfortunately, at this time it appears the secondary x16 slot can only be used for graphics. Ideally, we would like to be able to use any PCI-E device in any of the PCI-E slots, but it seems many of the chipset designs are taking a limited view of how PCI-E slots should be used - and this isn't just a problem with RD600 boards; most motherboards do not allow the use of non-graphics devices in the x16 slots.
