Troubleshooing ECC errors
Hello everyone,
I have a new build I built a few months ago and ever since I got the thing running - long story - I have been getting ECC errors. I have replaced all the cheap components and I want to check my suspects before going out and replacing the expensive components.
The build:
AMD Opteron 2435 x2
SuperMicro H8DAE-2
XFX AMD Radeon HD 6750
DDR2-400 RAM - Various 12 DIMM (see below)
Enermax NAXN 750AWT
OCZ Petrol SSD
Slackware64 13.37
The errors - I get thousands of these 3 line errors with 0 UECs:
Code:
[47175.704033] [Hardware Error]: MC4_STATUS: Corrected error, other errors lost: yes, CPU context corrupt: no, CECC Error
[47175.704046] [Hardware Error]: Northbridge Error, node 0: DRAM ECC error detected on the NB.
[47175.704051] [Hardware Error]: Transaction: RD (MEM), no timeout, Cache Level: L3/GEN, Participating Processor: SRC
The only things that change between errors are as follows:
"Northbridge Error, node 0"
alternates between
"Northbridge Error, node 1.
This alternation is sometimes immediate or could be minutes later.
"Participating Processor: SRC"
is sometimes
"Participating Processor: RES"
this seems to be random.
The RAM:
8x HP 1GiB - Cheap eBay RAM
PC2-3200R-333-10
4x Hynix HYMP351R72AMP4-E3 4GiB - SuperMicro tested RAM list
PC2-3200R-333-12
What I have done:
Replaced cheap eBay ram with SuperMicro suggested RAM.
Changed BIOS settings for scrubbing CPU cache.
What I haven't done but plan to do and plan to update this thread:
Test DIMM by DIMM on each CPU in a 1CPU configuration - test each DIMM twice, once on each CPU - I already did this with the HP RAM on 1 CPU and none seemed bad until I added more than 2 DIMM.
Disable ECC and run memtest86 overnight
I'm looking for some other ECC diagnostics tests as I have already done the "try each DIMM" test on one CPU with the HP RAM.
I've only recently installed the second CPU so it's been in a 1 CPU configuration for a few months.
