Re: Unable to use all the memory available

[Henry Addington <hs.addington@xxxxxxxxx>]

Hi James,

The server is Sun x4600 M2 which can handle 256GB memory according to Sun/Oracle Document... During the boot up, I can see the all the memory being counted. So, I think the BIOS is recognizing all the memory.... Thanks.
