How to View and Change DELL Server BIOS Settings

From DELL BIOS, you can view and changes several system settings. If you’ve not played around with these BIOS settings, just go to your system BIOS, view these settings to understand what they means.

For most part, you don’t have to change any of these default settings.

The screenshots below are from a DELL PowerEdge server.

1. Press F2 to enter BIOS

When the system is starting up, press F2 to enter the system setup, which will allow you to view (or modify) the DELL BIOS settings.

2. Memory Settings

On the top, you’ll see the system time and date. You can modify these if they are not correct.

Scroll down to ‘Memory Settings’ and press Enter, which will display more details about the memory configurations of the system as shown below. This displays memory information including RAM Size, Memory type, Memory speed, Video memory size, etc.

The following are some of the memory settings that can be changed from this screen. Press Space-Bar to change these values. The default values are shown in bold below.

  • System memory testing: Enabled (disabled)
  • Memory Operating Mode: Advanced ECC Mode (Optimizer Mode, Mirror Mode)
  • Node Interleaving: Disabled (enabled)
  • Memory Operating Voltage: Auto ( 1.5V )

3. Processor Settings

Scroll down to ‘Processor Settings’ and press Enter, which will display more details about the CPU of the system as shown below. In this example, you can see that it is 64-bit cpu, with 2.40 GHz processor speed, and bus speed of 5.86 GT/s, etc. If you are planning to install VMWare (or any virtualization server), you have to enable the “Virtualization Technology” in the CPU.

Use arrow keys to view more information about the processors. Now this shows the details about each and every processor on the system. In this example, the system has two Intel Xeon E5620 CPUs that has 4 cores each.
