Abstract 

By incorporating processors, chipset and integrated graphics from AMD and NVIDIA, the HP Business 
PC dx6050 delivers proven technologies at an extremely competitive price. 

The NVIDIA GeForce4 MX graphics integrated into the HP Business PC dx6050 can deliver a new 
level of high-performance graphics to the mainstream PC user. With its powerful nView multi-display 
architecture, Lightspeed Memory Architecture II and Accuview Antialiasing engine, the GeForce4 MX 
series delivers feature-rich, leading-edge graphics technology, performance and flexibility. 

Because the integrated graphics receive an allocation of DDR main memory, graphics performance 
can be tied directly to main memory performance. The graphics memory allocation is hidden from the 
operating system and cannot be used for other purposes. 

The HP Business PC dx6050 supports single-channel and dual-channel main memory configurations. 
Performance tests carried out by HP indicate that a dual-channel memory configuration can lead to 
significant performance gains.  

This white paper outlines main memory configuration issues and the performance testing, and offers 
recommendations for optimizing the memory configuration. 

Introduction
