ProLiant MicroServer Gen8 + 32GB RAM Bios Fix

Hi all. I have bought a ProLiant MicroServer Gen8 and wondering why the spec the ram is limited to 16GB RAM.
The chipset and CPU support up to 32GB  RAM. The MicroServer has 2 DIMM Slots and 16GB RAM modul exsist.


I asked the memory company Intelligent Memory  and asked if 32GB udimm will supported.
The Support answered me that the 16GB Ram limit is a restriction set by HP in the Bios.

Could you please remove this limitation / restriction from BIOS?

Lot of Customers have this wish because they use for Homelab for Study (Exchange, Sharepoint etc) Only Exchange already consume 8GB Ram and Sharepoint is recomend 12 GB)

Kind Regards

based on other forums I have found it looks like the maximum is 8GB per slot, the chipset can handle 4 slots (=32GB), but the server has only 2, hence the limitation.

Hope this helps!
