Memory oddity - 8gb installed and seen in system profiler, but only 4gb usable?

I have a second backup server setup, its an HP N40L microserver and installed are 2 x 4gb ECC sticks

 

System profiler sees the 2 sticks ok, but htop, and the dashboard only seem to be addressing 4gb.

 

Have attached diags. Any reason this is happening? Anything I have forgotten to do?

    Look in the BIOS for above 4G remap or similar options

    sorry only just got around to hooking the machine up to a monitor to test this. 

     

    Ive looked through the BIOS and can only see something about above 4G which seems to be related to graphics. Ive set this to enabled anyway, but no difference. 

     

    If I go into the memory section of the BIOS, it shows 2 4Gb sticks, but the main bios summary screen just shows the 4GB, most strange
