DIMM PFA Threshold
Exceeded.
Unsupported DIMM
Population.
Action
1. Refer to TIP H21455 for minimum code level.
2. Check the IBM support website for an
applicable retain tip or firmware update that
applies to this memory error.
3. Swap the affected DIMMs (as indicated by
the error LEDs on the system board or the
event logs) to a different memory channel or
microprocessor (see "Installing a memory
module" on page 47 for memory population
sequence).
4. If the error still occurs on the same DIMM,
replace the affected DIMM.
5. (Trained technician only) If the problem
occurs on the same DIMM connector, check
the DIMM connector. If the connector is
damaged, replace the system-board
assembly (see "Removing the system-board
assembly" on page 71 and "Installing the
system-board assembly" on page 71).
6. (Trained technician only) Remove the
affected microprocessor and check the
microprocessor socket pins for any damaged
pins. If a damage is found, replace the
system-board assembly (see "Removing the
system-board assembly" on page 71 and
"Installing the system-board assembly" on
page 71).
7. (Trained technician only) Replace the
affected microprocessor (see "Removing a
microprocessor and heat sink" on page 61
and "Installing a microprocessor and heat
sink" on page 65).
8. (Trained technician only) Replace the system
board (see "Removing the system-board
assembly" on page 71 and "Installing the
system-board assembly" on page 71).
1. Reseat the DIMMs and restart the server (see
"Removing a memory module" on page 45
and "Installing a memory module" on page
47).
2. Make sure that the DIMMs are installed in the
proper sequence (see "Installing a memory
module" on page 47).
