Hardware Diagnosis

Hello everyone,

I'm having an odd problem I've never encountered before and I'm at the point where the only things I have not replaced are the CPUs, Motherboard and Power Supply.

The errors:

[17100.704058] [Hardware Error]: CPU:0	MC4_STATUS[Over|CE|MiscV|-|AddrV|CECC]: 0xdc2b400013080a13
[17100.704069] [Hardware Error]: 	MC4_ADDR: 0x0000000001017d80
[17100.704071] [Hardware Error]: Northbridge Error (node 0): DRAM ECC error detected on the NB.
[17100.704075] [Hardware Error]: cache level: L3/GEN, mem/io: MEM, mem-tx: RD, part-proc: RES (no timeout)

This is the Slackware64 14.0 version of the errors. I get thousands of these and you can set your NTP by them. The first one is ALWAYS at 300 seconds after boot. I don't know if this pattern indicates anything.

The build:
2x AMD Opteron 2435
8x HP DDR2 400 (first RAM installed)
4x Hynix DDR2 400 (mobo. mfg. recommended)
SuperMicro H8DAE-2
OCZ Petrol 128G SSD
Enermax NAXN 750AWT
Slackware64 13.37 recently updated to 14. I tried CentOS live as well as Knoppix live and I get the same type of symptoms.

Everything is new except the RAM. I had 1 CPU installed and I tried everything I could to get the HP memory working. The Motherboard mfgr. said the RAM was not supported and "too slow because it's CAS 3". So I bought some of their recommended RAM which was only different in Tras and Trc by 1 CLK. This didn't fix anything.

Can someone with more experience solving this type of issue give me some assistance resolving this issue?

If I try one DIMM at a time with any of the RAM, I don't get any errors. I've done all the test I can think of and I will redo them if requested.

Here is the pattern:

See if you can find an update for your BIOS.

I had to install the latest BIOS to get the Opteron "Istanbul" Hex Core processors working with the motherboard.

I would recommend to check power supply output power to requirements of hardware and condition of capacitors on the mobo.
It could be also other sort of motherboard fault and even small chance that it is CPU. If you have two CPUs, try to change between them and if problem returns on CPU0 then mobo, if on CPU1 then it is CPU.

Considering AMD processors have their memory controllers built into them, it could easily be the CPU.

Unfortunately, it could easily be lots of other things too; hard to be certain without testing

I should recommend that first of all you should check your all hardware like power supply, MOBO or processors issue. After it you should check your BIOS. I am confident that it's work.
