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

Hello all, i have to HP DL20 gen9 server, with 64GB RAM installed but only sees 32Gb Ram
My current Bios version is 2.82
Can someone share uper Bios for this HP DL20 G9 server?

I’ve solved it be downgrading to an v5 cpu

Hi, 
is there really no other fix? 
I just upgraded to a v6 and only half of the RAM is found. 
The strange part, iLO shows me all four, but channel B has no voltage. 

Minimum Voltage
N/A

Hello Suman, 
Is there anything we can do? 
I got the parts from the HP spec list, but it makes no sense that upgrading the CPU to a v6 is cutting the RAM in half.

I got a DL20 gen9 as well.

I fix my problem with bios update, and it's see all the ram!
