In our database, I found only HMABAGL7M4R4N-VN & HMABAGL7M4R4N-UL as 128 GB Modules for the R730. You could wait for an Update from Firmware that could solve it. Because normally we update this to adding more compatibility. But I could not guarantee this to you when this happens.   Regards Martin
Hi! I've purchased single stick of Samsung DDR4 RDIMM 128gb with intentions of upgrading my R730 - currently 2x E5-2670v3 and 4x 16GB of Hynix RDIMM (slots A1, A2, B1, B2). With Samsung memory in any of the valid configurations (slot A3, B3 or even in A1) boot process gets stuck on "Loading BIOS drivers" and post code 0x4. When inserted into any other slot - A9 for example, system boots fine into OS with "DIMM populated out of order" info but additional RAM is not visible in OS nor in iDRAC. Both BIOS and iDRAC are fully updated (2.12.1 and 2.80.80.80 respectively). Exact memory models are:Samsung: M393AAK40B42-CWD6QHynix: HMA42GR7MFR4N-TFI even tested Samsung stick in other system (Asus C422 PRO/SE with xeon W-2133) and it works fine. What might be the cause of this?
