RCW/BCW Commands Trigger
The Kibra unit provides for triggering on RCW (Register Control Word)/BCW (Buffer
Control Word) commands. Because these commands are available only on RDIMM/
LRDIMM modules, you should select the correct memory type from RDIMM, LRDIMM or
SORDIMM to activate. Once one of these is selected, the RCW/BCW commands trigger is
available in the Advanced Triggers tab. The BCW commands are available only in DDR4
LRDIMM modules.
Figure 2.29 on page 62 shows RCW trigger option in DDR3 and
Figure 2.30 on page 62 shows RCW/BCW commands trigger on DDR4.
