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. Manually re-enable all affected DIMMs if the

"Installing the system-board assembly" on page
95).
6. (Trained service 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 94 and
"Installing the system-board assembly" on page
95).
7. (Trained Service technician only) Replace the
affected microprocessor (See "Removing a
microprocessor and heat sink" on page 85 and
"Installing a microprocessor and heat sink" on
