Hi,

We have upgraded our Dell R620 with four new dimm dual Rank of 8GB @1333MHz.

The older dimm were four dimm Single Rank of 4GB @1333MHz. So now we have eight dimm, this is our configuration:

From the bios and the S.O. we can see all the installed ram on the server, but we can't use over the original 16GB of memory.

 

In the iDrac and the S.O. we didn't find any error, what's the problem that limit the usage of the all ram?

Regars
