Dmidecode knows how many DIMM slots there are and with /sys/devices/system/edac/mc/mc$MC_id/csrow$row_id/ch* I count the channels per MC. have a peek here

Recall that the MCx tells us which processor as explained above. Y. BIOS DIMM Error Messages The BIOS displays and logs the following DIMM error messages: NODE-n Memory Configuration Mismatch The following conditions will cause this error message: The DIMMs mode is not The following is a summary of the steps that I used which I believe can be generalized to other motherboards.
I updated SA to 1.9 and am still getting the error. https://docs.oracle.com/cd/E19121-01/sf.x4240/820-3067-14/dimms.html A few systems with ECC memory use both internal and external EDAC systems; the external EDAC system should be designed to correct certain errors that the internal EDAC system is unable But I would like to hopefully resolve the issue before we do that. The DIMM module type (buffer) is mismatched.

Remember that each memory controller instance is managing half of the slots adjacent to each processor. http://dssoundware.com/ecc-error/ecc-error-correction-detected-on-bank-2-dimm-b.php Featured Post What Is Threat Intelligence?
When adding memory to a system that uses interleaving, the memory modules must be added in sets of two. The DIMMs are not registered. I hope this can be of help to you as it took me a couple of days to get this far.
There are still two csrows involved for the single DIMM in slot P2-DIMM3A (it is dual ranked), but the total size for each csrow is now only 2048. For UCEs, both LEDs in the pair flash if there is a problem with either DIMM in the pair. we have an error at 0x24bcfff3d0. See the x64 Servers Utilities Reference Manual for details.

If HERD is installed, it copies messages from /dev/mcelog to /var/log/messages. The user can then view individual errors (by time) to see details of the error. Only DDR2 800 Mhz, 667Mhz, and 533Mhz DIMMs are supported. Guertin. "In-Flight Observations of Multiple-Bit Upset in DRAMs".
this intrusion will also monitor the temperatures and other failures and perform actions which have been programmed. Retrieved 2009-02-16. ^ "SEU Hardening of Field Programmable Gate Arrays (FPGAs) For Space Applications and Device Characterization". The DIMM slot ID is calculated like this (in shell): MC_id * slots / mcs + channel_id * slots / channels + row_id / 2 With the DIMM slot ID I Most third party memory does not meet the stringent performance and quality guidelines required by IBM, and thus is not supported in IBM systems.
Sadler and Daniel J. a BIOS detected a Sync Flood caused this reboot. I suppose you could remove that DIMM, as long as the remaining memory is a supported configuration for your hardware. Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
At first I came to the same conclusion as yourself that it was the software but never got to the bottom of it..I was messing around with it for about 2 controller and a mem. IEEE.
