Server does not see all RAM

[Buls]

Hello. I have a problem. My HP proliant ML30 Gen9 server does not see all RAM after replacing the processor with a more powerful Intel xeon E3 1275 v6. Windows Server 2012 R2 Standard. Help (
Installed 48 Gb, sees 32, 16 in the reserve. Aida64 shows a limit on the north bridge (Intel Kaby Lake-H/S WS IMC) of 32 GB on CPU. Before worked fine with Xeon e3 1220 v5 and seen all 48Gb RAM. With RAM all right. Tested RAM one piece, everything works. Begins to reserve over 32Gb

Did everything possible. (swapped RAM, 2 times rearrange the new processor, check Maximum Memory option at msconfig >boot > advanced options). Update to last BIOS and ILo before replacing the processor. System Information in google disk https://drive.google.com/file/d/1F1QcY0GQ_7sIPzMqeCp5o6NxzkOLZMZI/view?usp=sharing

Hi,

Have you checked this article from Microsoft?
Here is the QuickSpecs for ML30 Gen9, but I dont see Intel xeon E3 1275 v6 as a compatible processor for this server.

797258-081 = 819800-001 = HPE 8GB (1 x 8GB) Dual Rank x8 DDR4-2133 CAS-15-15-15 Unbuffered Standard Memory Kit
797259-091 = 819801-001 = HPE 16GB (1 x 16GB) Dual Rank x8 DDR4-2133 CAS-15-15-15 Unbuffered Standard Memory Kit

Strange, the chipset is the same 1275 and 1270... ((  what do you think, with the processor 1240 v6. Will all 48 GB of RAM work?

@Buls Did you ever get this fixed?

I have the same problem with my dl20 gen9 uses an e3-1270v6 and an e3-1275v6

It can see my 48gb with the “stock” e3-1220v5
