R5 Aurora KB: Memory May Not Operate 2400Mhz XMP

Link: Alienware Aurora R5 owners may have XMP memory not operating at 2400Mhz

XMP memory at 2133 MHz.

If you enter the Basic Input/Output System (BIOS) setup on your Aurora R5 system equipped with XMP memory, the BIOS status information may indicate that the memory is running at 2133 MHz instead of 2400 MHz.

This is due to the default Performance Options setting of the BIOS from the factory.

Workaround

If you currently have an Alienware Aurora R5 with XMP memory you will need to change a BIOS performance setting.

To set the XMP memory to 2400 MHz, complete the following steps:

1. Enter BIOS setup during boot using the F2 function key.
2. Select Advanced
3. Select Performance Options
4. Within Performance Options, select XMP memory over-clocking and change the setting to XMP2.
5. Press the F10 key to save settings and reboot system.

Solution

Alienware Engineering has developed a BIOS update to correct the issue is targeted for release by the end of July 2016.

Systems shipped with this BIOS update will be correctly configured from the factory with the Default clocking rate for the XMP memory to run at 2400Mhz.
