" Correctable ECC memory error logging limit reached " Error found on IBM H22 Server

The Error Light Emitting Diode (LED) is illuminated on the chassis and the BladeCenter HS22 blade server front information panel. The Advanced Management Module (AMM) system status indicates that there is a " correctable ECC memory error logging limit reached " error. The AMM logs the following errors:

19 E Blade_05 12/08/09, 11:29:06 (octans012) Correctable memory error logging limit reached



The memory errors occurs in the following BladeCenter HS22 configuration:

• CPU-C states [Enable]
• Thermal Mode [Normal] double refresh rate
• 4 GB Samsung VLP DIMMs installed, Option 44T1488, Field Replaceable Unit (FRU) 44T1498

Method 1: Change Thermal Mode setting (preferred method)

1. Boot the blade into the F1 "System Configuration and Boot Management" screen. Highlight "System Settings". Press Enter and select "Memory". Select "Thermal Mode" and change the setting to "Performance".
2. Press the Esc key twice to get to "System Configuration and Boot Management" and then select "Save Settings" and "Exit Setup".
3. Follow the instructions on the next screen to exit the "Setup Utility".
4. Power the blade off for the changes to take effect and restart.

Changing "Normal" mode to "Performance" mode affects the way that the Dual In-Line Memory Modules (DIMMs) are refreshed. This results in a DIMM temperature warning message occurring at a 10 degree lower temperature. This causes no impact in most industry standard data centers.
