Dell R430, R530, R630, R730, R830, R930, M630, M830, FC430, FC630, FC830, T630 PowerEdge Servers may reboot after experiencing "Correctable memory errors"

Description

When the issue with Dell R430, R530, R630, R730, R830, R930, M630, M830, FC430, FC630, FC830, T630  PowerEdge Servers may reboot after experiencing "Correctable memory errors"

.  This has only see in BIOS version 2.3.x. Example:

MEM0701 Warning Correctable memory error rate exceeded for DIMM_xx.
MEM0702 Critical Correctable memory error rate exceeded for DIMM_xx.

Life Cycle  Log example:

2017-03-07 23:08:02 SYS1003 System CPU Resetting.
2017-03-07 23:08:02 SYS1001 System is turning off.
2017-03-07 23:08:02 MEM0702 Correctable memory error rate exceeded for DIMM_xx.

Solution

This has primarily been reported in R630 and R730.  The potential exists in all of 13G though, with BIOS version 2.3.x. A change was introduced in BIOS version 2.3.x for additional logging to SPD which introduced this particular issue.

The Q1 BIOS versions for the affected platforms fixes this server reboot in conjunction with a correctable error rate exceeded message. The following issue was fixed in the Q1 bios:

A NULL pointer dereferencing in BIOS enhanced SPD logging after memory correctable error critical threshold exceeded, would cause system to machine check or lock up.

To resolve the reboot issue, please update to Q1 FY18 bios.

Q1 FY18 bios fixed version numbers:
R430:  2.4.2
T430:  2.4.2
R530:  2.4.2
T630:  2.4.2
R630:  2.4.3
R730:  2.4.3
R830:  1.4.2
C4130:  2.4.2
C6320:  2.4.2
All modular blade units:  2.4.2

The T130, R230, T330, R330, and R930 are not affected by this issue.

Note: If correctable Memory errors occur after the update of BIOS to the Q1 BIOS version, please troubleshoot using the standard processes.
