mem3000 error codes
The two fields of the type two error are as follows:
• Field 1—Specifies the EWMB to which the information pertains
• Field 2—Specifies the type of DIMM detected as follows:
• x—Non-existent DIMM
• 0—80-bit DIMM
• 1—88-bit DIMM
The correspondence of these values to the actual DIMM locations is
shown in Figure 44.

Type three errors
The type three error (shown in Figure 45) is used only by class 3 subtests
to report spurious single-bit ECC errors that occur during testing. The
test is designed specifically to bring out these types of failures. However,
if failures of other types occur, they are reported in their respective
format.

There are five fields separated by / symbols. The meaning of each field is
as follows:
• Field 1—Specifies the EWMB on which the failure was detected
• Field 2—Specifies the DIMM on which the failure was detected
• Field 3—Specifies the SMAC error address CSR value
• Field 4—Specifies the syndrome bits
• Field 5—Reminds that this is a single bit ECC error
