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 - HP dx6050 | Configuring Graphics Memory for HP Business PC dx6050 - Page 3
end-user can manually specify an allocation of up to 128 MB. Note: If the end-user specifies a graphics memory allocation that exceeds available main memory, the BIOS defaults to the Auto setting. HP recommends using the Auto feature. Graphics Driver Not only is graphics memory size important, so - HP dx6050 | Configuring Graphics Memory for HP Business PC dx6050 - Page 4
may vary with system configuration and driver versions. Memory Speed Graphics performance depends, in part, on memory speed. For convenience, the HP Business PC dx6050 supports two DDR memory standards: • PC2100-266 MHz • PC2700-333 MHz However, actual memory speed is constrained 3 by the speed - HP dx6050 | Configuring Graphics Memory for HP Business PC dx6050 - Page 5
the HP Business PC dx6050. Using an alternative driver may impact system performance (as shown in the Appendix). Summary The NVIDIA GeForce4 MX graphics integrated into the HP Business PC dx6050 automatically receive an allocation of up to 64 MB of DDR main memory. The HP Business PC dx6050 supports - HP dx6050 | Configuring Graphics Memory for HP Business PC dx6050 - Page 6
or downloaded from the HP website is an HP driver; any other graphics driver is an alternative driver. Example 1 In this example (shown in Figure 1), the end-user is deploying matched DIMMs. The graphics driver can be HP-or an alternative. Figure 1: Dual-channel memory with matched DIMMS.

DIMMs. There is an HP graphics driver. Figure 2: Dual-channel memory with mismatched DIMMS, HP graphics driver. The BIOS maps upper memory to be 64 bits wide, lower memory to be 128 bits wide. The BIOS maps the specified graphics memory allocation to the top of the memory space (the larger DIMM - HP dx6050 | Configuring Graphics Memory for HP Business PC dx6050 - Page 8
