Many users have reported problems with their system after upgrading their RAM. The following information was supplied by an SGI support engineer and will help with the identification of a faulty module.
Symptom:
Unrecoverable ECC error in System Log
STOP: 0x00000080 Hard ECC error Blue Screen of
Death.
Cause/Description:
Flawed DIMM or bad DIMM socket on the Motherboard
Resolution:
4 different quantifiable STOP: 0x00000080 errors:
STOP: 0x00000080 [0x 000A4000, 0xXXXXXXXX, 0xXXXXXXXX,
0x00000000] or
The errors may somehow be related to the RAM Speed
Check errors in the Hardware Diagnostic screen which return 0x00000080 addresses
or codes. Use the second parameter hex number
and the chart below to determine the faulty DIMM module. Once located, replace
the faulty DIMM.

STOP: 0x00000080 [0x000E4000, 0xXXXXXXXX, 0xXXXXXXXX, 0x00000000]
These are fixed by replacing the motherboard
STOP: 0x00000080 (0x00000000, 0xXXXXXXXX, 0xXXXXXXXX, 0xXXXXXXXX)
Go into the PROM and activate Extensive Memory Tests and the L2 ECC Error Correction. After resetting the machine, there will be a Memory Test failure that looks like this:
Memory Test Failure 0x00000000
The 0x00000000 number specifies which DIMM is bad. The last two hex numbers will be A, B, C, or D with a 1-6. The A - D tell which bank of six and the number tells which module in that bank. Example: 0x001234A4 would mean a bad DIMM in Bank A, module 4.
STOP: 0x00000080 (0x002E4000, 0x1C9C3000, 0x86F4DFE5, 0x00000000)
Hardware malfunction Genuine Intel CPU 6.7.2 IRQL: 1E BPC sysver 0xF0000565
This error can be circumvented by enabling the “Expanded Power On Tests” in the PROM. My guess is that this is related to the CPU initialization problem and will truly be corrected with a motherboard revision update. The “Expanded Power On Tests” seem to delay initialization enough to sync the CPUs
STOP: 0x00000080 (0x002e4000, 0x1341b000, 0xcbddf6dc, 0x00000000)
Hardware malfunction. CPUId Genuine Intel IRQL: 1E
