6.3.9. The DDR4 Tab
This tab allows you to read and write DDR4 memory on your board.

The following sections describe the controls on the DDR4 tab.
Start
Initiates DDR4 memory transaction performance analysis.
Stop
Terminates transaction performance analysis.
Performance Indicators
- Write, Read and Total performance bars: Show the percentage of maximum theoretical data rate that the requested transactions are able to achieve.
- Write (MBps), Read (MBps) and Total (MBps): Show the number of bytes analyzed per second.
- Data Bus: 72 bits(8 bits ECC) wide and the frequency is 1066 MHz double data rate. 2133 Mbps per pin. Equating to a theoretical maximum bandwidth of 136,512 Mbps or 17,064 MBps.
Error Control
- Detected errors: Displays the number of data errors detected in the hardware.
- Inserted errors: Displays the number of errors inserted into the transaction stream.
- Insert: Inserts a one-word error into the transaction stream each time you click the button. Insert Error is only enabled during transaction performance analysis.
- Clear: Resets the detected error and inserted error counters to zeroes.
Number of Addresses to Read and Write
Determines the number of addresses to use in each iteration of reads and writes.
