Issue with DIMM slots on X10DRC-LN4+

[java]

I've bought this motherboard X10DRC-LN4+ more than a year ago, but only now discovered the issue, because I installed the second CPU. Three DIMM slots are not working. When I install one DIMM into P2-DIMMF1, I get this error during server start up "Uncorrectable Memory Component Found (P2-DIMMF1)"

Some more details :
MB : X10DRC-LN4+
MB Firmware Revision : 01.85
BIOS Version : 1.0b
DIMM type : KVR21L15Q4/32
DIMM count : 8 (total RAM = 256GB)
CPU : 2 x E5-2697V3

Any help will be greatly appreciated

Thats a DIMM error not necessarily a DIMM Slot error.
Try moving around DIMMs and you might see this error appear in another Slot.
Recently had 16 identical DIMMs of which 2 had this same error...

The problem is not in DIMMs themselves, I tested them, all DIMMs are ok, the slots marked in image, are "bad" slots, where DIMMs don't work and that message appears during server boot up

You've swapped CPU positions and all the DIMMs and confirmed that it's the motherboard?

 

[java]

j_h_o,
"You've swapped CPU positions" - no I didn't, I didn't even imagined that the issue could be in CPU

But it is very unlikely that the issue is in the second CPU, the server is working now, maybe not in the optimal way, because I placed the DIMMs in other slots, not as described in the manual.

I understand that the memory controller is located in the CPU itself, but how the hell can it be partially (because other DIMMs are ok) broken ? I've never seen such issue before

Bent CPU socket pin(s).

Bent CPU socket pin(s).

Definitely a likely culprit. Since you're out of the warranty period on the board it's worth swapping CPUs to see if that helps. If you're lucky it's the CPU and you can return it.

Have you ever been able to resolve this?

Looks like I am hitting the same issue with like every Supermicro E5 board I get my hands on - this is effing annyoing
I am out of modules to swap around with my newest board ... When in contacted SM with one of the boards they said 'board error', but then I swapped in some other modules and at least a few of the slots worked, so i am not sure thats true

Hmm, something is not right.

Cleaned RAM prior to install?

When you install the RAM do you just push it down or do you verify each side as well as very gently rock it side to side?

if you have H310 cards, try removing for troubleshooting

Have not cleaned them - didn't occur to me since they are working in other boards, but will give it a try
And I guess I am not too gentle with those modules

Re H310 - empty board, only CPU and ram - just got it (used/ebay)

Oh my, embarrassingly stupid error this time - wrong CPU in use (v4 vs v3)
I though I had verified that, turns out I did not.
