DDR4

DDR4 (double data rate fourth generation) memory is a higher-speed successor to the DDR2 and DDR3 technologies and allows up to 512

GB in capacity, compared to the DDR3's maximum capacity of 128 GB per DIMM. DDR4 synchronous dynamic random-access memory is

keyed dierently from both SDRAM and DDR to prevent the user from installing the wrong type of memory into the system.

Technology and components 53

DDR4 needs 20 percent less or just 1.2 volts, compared to DDR3 which requires 1.5 volts of electrical power to operate. DDR4 also supports

a new, deep power-down mode that allows the host device to go into standby without needing to refresh its memory. Deep power-down

mode is expected to reduce standby power consumption by 40 to 50 percent.

DDR4 Details

There are subtle dierences between DDR3 and DDR4 memory modules, as listed below.

Key notch dierence

The key notch on a DDR4 module is in a dierent location from the key notch on a DDR3 module. Both notches are on the insertion edge,

but the notch location on the DDR4 is slightly dierent, to prevent the module from being installed into an incompatible board or platform.

Figure 4. Notch dierence

Increased thickness

DDR4 modules are slightly thicker than DDR3, to accommodate more signal layers.

Figure 5. Thickness dierence

Curved edge

DDR4 modules feature a curved edge to help with insertion and alleviate stress on the PCB during memory installation.

Troubleshooting your computer

You can troubleshoot your computer using indicators like diagnostic lights, beep codes, and error messages during the operation of the

computer.

Enhanced Pre-Boot System Assessment — ePSA

diagnostics

The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the

BIOS and is launched by the BIOS internally. The embedded system diagnostics provides a set of options for particular devices or device

groups allowing you to:

• Run tests automatically or in an interactive mode

• Repeat tests

• Display or save test results

• Run thorough tests to introduce additional test options to provide extra information about the failed device(s)

• View status messages that inform you if tests are completed successfully

• View error messages that inform you of problems encountered during testing

CAUTION: Use the system diagnostics to test only your computer. Using this program with other computers may cause invalid

results or error messages.

NOTE: Some tests for specic devices require user interaction. Always ensure that you are present at the computer terminal

when the diagnostic tests are performed.

Running the ePSA diagnostics

1 Power-on the computer.

2 As the computer boots, press the F12 key as the Dell logo appears.

3 On the boot menu screen, select the Diagnostics option.

4 Click the arrow key at the bottom left corner.

Diagnostics front page is displayed.

5 Press the arrow in the lower-right corner to go to the page listing.

The items detected are listed.

6 To run a diagnostic test on a specic device, press Esc and click Yes to stop the diagnostic test.

Note the error code and validation number and contact Dell.

Power supply- built in self test (BIST)

The Dell OptiPlex, and Desktops(AIO) features a new Power Supply Unit (PSU) Built -in Self Test (BIST). BIST can now be performed by

simply connecting the AC power cord to the PSU.

1 Turn o the computer.

2 Disconnect the power cord from the PSU and wait for 15 seconds.

Troubleshooting your computer 69

3 After 15 seconds, connect the power cord back to the PSU.

a If the LED stays on for 3 seconds and turns o, it indicates the PSU is functional. Continue with troubleshooting steps for other

devices.

b If the LED does not come on, it indicates a hardware failure. The failed component can be PSU, system board or any device.

Step to conrm that PSU is Defective

CAUTION: Ensure that you take adequate safety precautions before accessing the internal components of your system. Go

through the Service Manual to know the steps to access the PSU and its cables.

1 Disconnect the power cord from the PSU.

2 Disconnect the PSU cables from the system board.

3 Connect the power cord to the PSU

a If the LED stays on for 3 seconds and turn o, it indicates the PSU is functional. Continue with troublshooting steps for other

devices.

b If the LED does not come on, it indicates a PSU failure. Dispatch PSU only

Power supply

All power supply units include a self-test ability in an isolation mode.

Customers can test the health of the power system by pressing the test button. The button is lit by a signal in the power supply called

Power Good (PG). When the +3.3v, +5v, and +12v rails are up and within spec, the PG signal turns on, lighting the self-test LED. By

removing the cable harness in units that do not pass this test, the customer, or technician can isolate the failure's cause to an attached

device of the power supply.

LCD built in self test (BIST)

All-in-One (AIO) systems supports LCD BIST similar to any other Dell systems that have BIST test implemented. It allows the user to isolate

the LCD during troubleshooting to determine which sub-system is at fault. The main dierence is the lack of an integrated keyboard scan

controller in the AIO. When BIST is initiated, an internal generated pattern from the LCD will be emitted for user's observation. This pattern

will go by sequence through this pattern. Black-White-Red-Green-Blue or a White-Black-Red-Green-Blue where each pattern is emitted for

2 to 3 seconds. The following images displays the pattern of the colors on the LCD.

70 Troubleshooting your computer

Troubleshooting your computer 71

Invoking BIST with user modes

There are two methods to invoke the LCD BIST .

• OSD Toggle

• ePSA

OSD toggle

The rst method of user initiation is via OSD toggle button. The user should press the OSD toggle button and hold it in while the power

button is applied to turn the AIO on. This is the hardware-initiated method that does not require the CPU and BIOS to be functional. The

panel will stay in BIST mode until the BIOS reboots the system. The test duration is approximately 20 seconds which allows 2 cycles of

color bar patterns.

To invoke the BIST test via OSD Toggle:

1 Press and hold down the OSD toggle button.

2 Press the power button to turn on the computer while holding down on the OSD toggle button.

NOTE: The OSD toggle is located at the right side of the chassis, just above the Hard Disk indicator light.

ePSA

The second method to troubleshoot is via ePSA entry. The user initiates a Pre-Boot POST via F12 function key and the system enters

ePSA. The ePSA menu will have an LCD BIST selection that asserts the proper signals via BIOS commands. The BIST mode will loop for

approximately 20 seconds giving 2 cycles of color bar patterns that the user can observe. The time period is controlled by BIOS. After the

time period, the BIOS will return the system to the ePSA menu.
