Tony/Aris,
I got yesterday an HP ML350 G9, equipped with Sandy Bridge EP CPUs (E5-2640v4).
I'm running Kernel 4.11 there.
AFAIKT, Sandy Bridge EP has 4 channels per memory controller, right?
That would match the number of memory slots on this machine (24 slots).
Yet, EDAC is only identifying 3 channels per CPU:
$ ras-mc-ctl --layout
+-----------------------------------------------------------------------+
| mc0 | mc1 |
| channel0 | channel1 | channel2 | channel0 | channel1 | channel2 |
-------+-----------------------------------------------------------------------+
slot2: | 0 MB | 0 MB | 0 MB | 0 MB | 0 MB | 0 MB |
slot1: | 0 MB | 0 MB | 0 MB | 0 MB | 0 MB | 0 MB |
slot0: | 16384 MB | 0 MB | 16384 MB | 16384 MB | 0 MB | 16384 MB |
-------+---------------------------------------------------------------------------+
So, it seems that either the BIOS is hidden the other channel or
there's something wrong with SandyBridge EP support at sb_edac driver.
Thanks,
Mauro
