DFI LanParty UT RDX200 CF-DR Motherboard Chipset Intro Introducing Radeon Xpress 200 CrossFire ATI’s Radeon Xpress 200 CrossFire chipset for both Intel® and AMD-based processors is built for the dual slot PCI Express architecture and delivers leading graphics performance, bandwidth, and advanced functionality for the ultimate gaming platform. Multiply and Conquer with CrossFire. Radeon Xpress 200 CrossFire for AMD Processors • AMD Athlon 64 X2, AMD Sempron, AMD Athlon 64 and AMD Athlon 64 FX processors • Support for 64-bit extended operating systems • 800MHz and 1GHz HyperTransport interface speeds Best-in-class Performance for CrossFire Operation With dual dedicated and balanced PCI Express graphics ports, the Radeon Xpress 200 CrossFire supports up to 2GB/s peak bandwidth to both graphics cards making it the ideal chipset for Multi GPU systems. The unique chipset architecture creates no interference with any other PCI Express peripherals. CrossFire operation does not limit other PCI Express functionality. Built for the Enthusiast The Radeon Xpress 200 CrossFire is an enthusiast-class chipset that delivers unmatched performance when paired with two ATI-based graphics cards. This chipset supports all three CrossFire performance rendering modes: SuperTiling, Scissor, and AFR. CrossFire acceleration is enabled by default for every game all the time making it the fastest gaming platform out there. Stunning Overclocking Capabilities ATI’s Radeon Xpress 200 CrossFire offers gamers and enthusiasts tons of advanced features that will help move their performance to the next level. For the overclocking enthusiasts, the Radeon Xpress 200 CrossFire provides a wide array of adjustment capabilities such as memory voltage, CPU core voltage, chipset voltage and others to allow each user to maximize their performance potential. Features High Build Quality and Excellent Board Layout The RDX200 is built to perfection using a 6-layer PCB and high-quality components. UV sensitive (glow in the dark under dark light) slots, and a magnetic-levitation fan on the chipset heatsink make this mobo quite the looker at LAN parties as well. DFI applies a unique board layout by locating 4 DIMM slots between the CPU and IO ports. This design works very well to keep the air flowing and component temperatures down. ATI CrossFire Multi VPU Technology Support The DFI LanParty UT RDX200 CF-DR is a CrossFire motherboard. That is to say that it incorporates full support for ATI CrossFire technology. As is the case with nForce4 SLI mobos, the two PCI Express x16 slots on the RDX200 can be configured for x16 + x1 mode in single graphics card mode or dual x8 mode for ATI CrossFire mode. Unlike many nForce4 SLI mobos, however, the DFI RDX200 doesn’t feature a paddle card for changing between single and dual graphics card modes. Instead, the switching is done via the electronics. All the user has to do is to perform the switch in the BIOS or let the BIOS detect it automatically. 100% Japanese Sourced Capacitors/ 4-Phase PWM A 4 phase PWM design provides the system extra stability and reliability under heavy-loading and overclocking conditions. The heatsinks attached to the MOSFETs ensure the temperatures stay in the safe zone when the processor runs under full loads. All capacitors on this motherboard are 100% Japanese-sourced for unquestionable levels of quality. The 24-pin and 8-pin/4-pin power connector are shown above located side-by-side at the right edge of the board. Users can use either a standard 4-pin or the more robust 8-pin connector on the DFI motherboard.

The DFI RDX200 goes even further, extending memory voltage to 4.03V and CPU voltage to as high as 2.108V. The most exciting one has to be the "impossible" option of running 4DS (Dual Side) DIMMs at 1T Command Rate and a working CAS 1.5 option in the BIOS. PCI Express x16 slots Configuration: Dual Slot Configuration Enable/Disable GFX0 Link Width 16X/12X/8X/4X/1X GFX1 Link Width 12X/8X/4X/1X (only available when “Dual Slot” enabled) The PCI Express x16 slot operating modes are easily configured in the BIOS, and the user can choose the specific link width of the two slots as well.

That’s really good news for enthusiasts and experienced users as they have the potential to achieve higher performance levels through the tuning of these parameters to better fit their own systems. DRAM Configuration Parameters Options DQS Skew Control Auto/Increase/Decrease DQS Skew Value 0~255 DRAM Driver Strength Auto/Level1~15 DRAM Data Driver Strength Auto/4/3/2/1 MAX Async Latency Auto/0.0～15.0ns Read Preamble Time Auto/2.0~9.5ns Idle cycle Limit 0/4/8/16/32/64/128/256 Cycle Dynamic Counter Enable/Disable R/W Queue Bypass Auto/2X/4X/8X/16X Bypass MAX Auto/0~7X 32Byte Granularity Auto/Enable/Disable Another area in which the RDX200 actually exceeds its predecessor (i.e. the LanParty nForce4 series) is this: most DRAM modules run perfectly using the “By SPD” mode on this RDX200. This was not the case with previous LanParty boards as manual settings were always needed. This improvement is especially important for DIY beginners as memory compatibility issues are greatly reduced.
