1. Follow AMD's recommendation that" CPU Disconnect Function "should be iimplemented to make CPU slow down in idle state, and the default value sets up to Enable. 2. Follow AMD's recommendation to revise the trigger timing of LM90 for Palomino CPU(model 6). 3. Fix the SCSI BIOS malfunction problem when three add-on cards installed together, PCI S3 VGA GF4 MX420 DC390U3W(at PCI-1). 4. Supports Barton 2600 (333 FSB)and Thorton2000 (266 FSB)/2200 (266 FSB)/2400 (266 FSB)/2600 (333 FSB). 5. Revises some CPU frequency(1466,1666,1916,2166) to be AMD officially suggested figures.(1467,1667,1917,2167). 6. BIOS compile date 4/02/2003.Specifications:Based on the VIA KT400 chipset with supporting for the latest Athlon, Athlon XP, Barton, and Duron CPUs, the KD7-RAID offers unparalleled performance for your PC. The KD7-RAID features 4 DDR DIMM slots, two of which support high-speed DDR 400 memory. The KD7-RAID also supports the latest AGP 8X standard, providing you unprecedented graphic performance. ATA133 with RAID 0, 1, 0 1 function makes both the speed and the security of your data vastly improved. Combining the latest technologies with ABIT engineering and innovation, the KD7-RAID delivers the power to drive the most demanding applications. AGP 8XAGP 3.0 8X spec support high performance graphic process purpose and at a peak bandwidth of 2.1 GB/s. DDR400Supports up to 2GB of DDR333/400 at a peak bandwidth and 3.5GB of DDR200/266 of 2.7/3.2GB/s at 1.6/2.1 GB/s 5bit FID (Frequency ID)By ABIT 5-bits FID Override technology, users can get variety of CPU over-clocking sets. ABIT CPU H.T.P (Hardware Thermal Protection) ABIT CPU H.T.P. uses pure hardware detection, which not like others use software detection to prevent CPU overheating. ABIT CPU H.T.P provides more reliable result for customers' investment. ABIT SoftMenu OverclockingThe overclocking function includes CPU frequency, Vcore, multiplier, chipset & DDR voltage and AGP VDDQ voltage adjustment available to maximize your system performance. USB 2.0Support speed up to 480 Mbps. Approximately forty times faster than conventional USB 1.1 6-Channel Audio and S/PDIF OutLet you enjoy 6-channel audio without having to buy advanced sound cards. RAID 0/1/0 1Supports the most advanced ATA133 HDDs with RAID 0/1/0 1 onboard HPT372 RAID controller enables enhanced functionality and HDDs performance without the cost of additional add-on cards.It is highly recommended to always use the most recent driver version available.Do not forget to check with our site as often as possible in order to stay updated on the latest drivers, software and games.Try to set a system restore point before installing a device driver. This will help if you installed a wrong driver. Problems can arise when your hardware device is too old or not supported any longer.
