You cannot do unsupported memory configurations on a dell, and expect it to work. It "could" work, but more likely will simply give you an error   [IMAGE]   You should check the user manual for the 5820. Those configurations are supported. Anything else may just cause an error preventing to boot, especially if you test adding a single extra ... You want to test that 32gb dimm, your likely bet is try the first row ( 8gb single dimm ) and use the 32gb in its place.
Hello all, ** Does anybody know if a Dell Precision 5820 Tower with a ‘Sky Lake Series CPU’ allows 256 GB of RAM, and how to install the 32 GB DIMMs? I explain better the mater next: We bought (a public research centre) a workstation Dell Precision 5820, with a ‘Sky Lake Series’ Intel Xeon CPU (likely the W-2123 processor). From the 'Owner's Manual’ it seems that ‘Sky Lake Series’ allow 256 GB of RAM. The motherboard has 8 DIMM slots and the manual says ‘4 channel memory up to 256 GB…with Sky Lake Series CPUs’. Our Dell supplier told me that for my service tag only DIMMs of 16 GB were indicated, without negating that 32 GB were perhaps possible. 16 GB DIMMs would give maximum 128 GB of RAM. So, I risked to buy one DIMM of 32 GB (KTD-PE426/32G DIMM from Kingston) to test the mater. I installed only this one 32 GB DIMM in a Black slot (I kept the four 8 GB DIMMs already installed in four White slots). The workstation beeped and did not start. I removed the DIMM and it started OK again. I wonder if two equal DIMMs of 32 GB, installing one in a White slot and the other in a Black slot may work to create a kind of ‘dual memory per channel’ 2DPC. But, I do not have the proper IT knowledge, and I would not like to buy another 32 GB DIMM and fail. Thank you very much for any help.
Can 32GB DIMMs work in a Dell Precision 5820 SkyLake-CPU workstation?
