Table 2-1. D4 Token Table (continued) Token 02A9 02AA 02AB 02AC 02AD 02AE 02B6 02B7 02B8 02C5 02C6 02C7 02C8 02C9 Setup Option Description DRAM Prefetcher Disables DRAM references from triggering DRAM prefetch requests. DRAM Prefetcher Turns on the DRAM prefetch unit in the Northbridge. HW Prefetch Training on SW Disables hardware prefetcher from considering software prefetches when detecting strides for prefetch requests. HW Prefetch Training on SW Enables Hardware prefetcher considers software prefetches when detecting strides for prefetch requests. (default) SR-IOV Global Enables BIOS support for SRIOV devices. Enable SR-IOV Global Disables BIOS support for SRIOV devices. Enable Memory Indicates all DIMMs in the system are operating at 1.5 Operating Voltage volts. Memory Indicates all DIMMs in the system are operating at Operating Voltage 1.35 volts. Memory This setting indicates the memory operating voltage Operating Voltage will be set automatically by the Memory initialization code and depending upon the installed DIMM's capability and the memory configuration of the system. This is the default setting and will set the Memory Operating voltage to the POR voltage. DCU Streamer Enables the DCU Streamer Prefetcher. (default) Prefetcher DCU Streamer Disables the DCU Streamer Prefetcher. Prefetcher Data Reuse Optimization Sets to enable for HPC applications. (default) Data Reuse Optimization Sets to disable for energy efficiency. QPI Bandwidth Sets to compute for computation-intensive Priority applications. (default) Using the System Setup Program 115
