Example 2 In this example (shown in Figure 2), the end-user is deploying mismatched 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). Since upper memory is 64 bits wide, graphics performance is sub-optimal. 7
