Make sure that the server contains DIMMs.2. Reseat the DIMMs.3. Install DIMMs in the correct sequence (see“Installing a memory module” on page 152).4. Clear CMOS memory to re-enable all the memoryconnectors (see Table 2 on page 16).0058001 PFA threshold exceeded 1. Update the server firmware to the latest level (see“Updating the firmware” on page 193).2. Reseat the DIMMs and run the memory test (see“Running the diagnostic programs” on page 78).3. Replace the failing DIMM, which is indicated by alit LED on the system board.0058007 DIMM population is unsupported. 1. Make sure the installed DIMMs follow thepopulation rules and sequence described in“Installing a memory module” on page 152.2. Reseat the DIMMs, and then restart the server.3. Remove the lowest-numbered DIMM pair of thosethat are identified and replace it with an identicalpair of known good DIMMs, then restart theserver.4. Return the removed DIMMs, one pair at a time, totheir original connectors, restarting the server aftereach pair, until a pair fails. Replace the DIMMs inthe failed pair with identical known good DIMMs,restarting the server after each DIMM is installed.Replace the failed DIMM. Repeat this step untilyou have tested all removed DIMMs.5. (Trained service technician only) Replace thesystem board.0058008 DIMM failed memory test. 1.
