To clarify, you are seeing the server say that ECC is now disabled? Seeing that is likely due to the Memory Mode being set to ECC, but with a dimm present in A1 it will disable that memory mode. To populate the server in Adv ECC mode would need the dimms to be in slot A2, A3, and B2, and B3.
If you set the servers Memory Mode to Optimizer then the dimms indeed would go to A1, A2, and B2, B3.
To verify the mode the server is set to just access the BIOS (F2 on startup) and then under Memory Settings, verify what Memory Operating Mode is listed as.
Lastly, although the R710 does support 16gb dimms, there are some processors that may not be compatible with using the 16gb dimms. Let me know what processor is installed and I can let you know compatibility.
I have a dell r710 server and would like to fill all the memory slots as I have 16GB memory modules which would give a total of 288GB and would like to do this without giving those messages at server startup saying that MEMBIST Failure: DIMM B1 for example.
I have 2 R710 Servers i combined to get more performance. It will not ever boot with the 3 x 2gb in A1,A2,A3 and 3 x 2gb in B1,B2,B3. It will boot if i have memory in just A1,A2,A3. Any thoughts on how to make this memory work? @DELL-Chris H

Let me know.

Thanks,
changed positions for A2, A3, B2, B3 and changed the BIOS to ECC Advanced Mode, now is ok. thank you

Chris good afternoon,
I have a dell r710 server and would like to fill all the memory slots as I have 16GB memory modules which would give a total of 288GB and would like to do this without giving those messages at server startup saying that MEMBIST Failure: DIMM B1 for example.

Hi,
Do you have 2 processors installed in the server, with populated A1-3 and B1-3? Also, make sure in BIOS, the memory mode is Optimizer.
Have you also done BIOS, LCC and iDRAC update to the latest?
