Abstract By incorporating processors, chipset and integrated graphics from AMD and ATI, the HP Business Desktop dx5150 delivers the latest technologies at an extremely competitive price. The ATI RADEON XPRESS 200 chipset built into the dx5150 brings both high-performance 3D graphics and the PCI-Express upgradability to the mainstream PC user. The RADEON XPRESS 200 is the first chipset solution in the market with a DirectX 9.0 graphics core that is a derivative of RADEON X300.
Main Memory Configuration Single-channel vs. Dual-channel The dx5150 business desktop includes four DIMM slots, organized in two independent memory channels. A “dual channel” configuration might put identical DIMMs in the first slot of each channel, for example, so that both channels operate simultaneously. This organization provides better memory performance.

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM3 operate in memory channel A. Sockets XMM2 and XMM4 operate in memory channel B. The system will automatically operate in single channel mode or a higher-performing dual channel mode, depending on how the DIMMs are installed.
Memory Type and Speed Supported Memory Types The dx5150 HP Business Desktop supports industry-standard 184-pin unbuffered DDR I SDRAM DIMMs, designed with 128Mbit, 256Mbit, 512Mbit, and 1Gbit memory technologies. ECC is not supported. Supported Memory Speeds The dx5150 HP Business Desktop ships with memory that meets the PC3200 specification, which runs at a memory bus speed of 400 MHz.
