Upgrading RAM in HP ProLiant ML150 gen6

We tried upgrading from 16gb ram to 24gb in our server, but it appears that it’s a "Invalid memory configuration".

Currently, we have the following RAM in use:


BankLabel           Capacity               DeviceLocator   Manufacturer                    PartNumber                     

BANK0                  4294967296         CPU 1 DIMM 2   Nanya                   NT4GC72B8PG0NF-CG   

BANK1                  4294967296         CPU 1 DIMM 1   Nanya                   NT4GC72B8PG0NF-CG   

BANK2                  2147483648         CPU 1 DIMM 4   Samsung              M391B5673EH1-CH9       

BANK3                  2147483648         CPU 1 DIMM 3   Micron                  18JSF25672AY-1G4D1     

BANK4                  2147483648         CPU 1 DIMM 6   Micron                  18JSF25672AZ-1G4F1      

BANK5                  2147483648         CPU 1 DIMM 5   Micron                  18JSF25672AZ-1G4F1      1C515DE1           


And we replaced them all with 6x:

4Gb 2Rx4 PC3-10500R-9-10-J0 ( attached image is of this new ram ) 

We only have on processor in, but from what we read in the manuals, it should work.

But apparently it fails to work properly. Bios claims theres only 8gb ram, and windows server uses 8gb ram while 16gb is "hardware reserved".


Anyone has information as to how we should proceed to get the new ram to work ?
