This menu offers options to change the memory settings.
Item | Options | Description |
---|---|---|
System Memory Details | N/A | Displays status of the system memory. |
Total Usable Memory Capacity | yyyy GB | Displays Total Usable Memory Capacity. |
Memory Speed |
| Selects the desired memory speed. [Maximum Performance] maximizes performance. [Balanced] offers a balance between performance and power. [Minimal power] maximizes power savings. When a preset mode is selected, the low-level settings are not changeable and will be grayed out. To change the settings, choose System Settings > Operating Modes > Choose Operating Mode >Custom Mode. |
Memory Power Management |
| [Disabled] maximizes performance and minimizes power savings. [Automatic] is suitable for most applications. When a preset mode is selected, the low-level settings are not changeable and will be grayed out. To change the settings, choose System Settings > Operating Modes > Choose Operating Mode >Custom Mode. |
Socket Interleave |
| Sets Socket Interleave to NUMA(Non Unified Memory Architecture) or Non-NUMA. [NUMA] means that memory is not interleaved across processors. [Non-NUMA] means that memory is interleaved across processors. Note Setting change requires a Power Good reset to take effect. |
Patrol Scrub |
| Enables or disables Patrol Scrub which proactively searches the system memory to repair correctable errors. When [Enabled] is selected, Patrol Scrub takes effect at the end of POST. |
Memory Data Scrambling |
| Enables or disables Memory Data Scrambling. |
ADDDC Sparing |
| Enables or disables ADDDC Sparing. ADDDC Sparing is not supported when the server has x8 DIMM, 9x4 value DIMM or memory is set to [Mirror mode] (Full or Partial). |
Page Policy |
| [Adaptive] can improve performance for applications with a highly localized memory access pattern. [Closed] can benefit applications that access memory more randomly. |
Cold Boot Fast |
| Enables or disables Cold Boot Fast. |
AC Boot Fast |
| Enables or disables AC Boot Fast which is for AC boot only. |
Memory Test |
| Enables or disables Memory Test during normal boot. |
2x Refresh Rate |
| [Disabled] sets the system with 1x refresh rate. [Auto] sets the system with 2x refresh rate if it is supported by the system. Setting it to [Auto] can mitigate Rowhammer issue, but that might have a performance impact. 2x refresh rate is not supported by system that has 16Gb 3DS with 4 Die DIMM. |
