Thank you for you reply.

I have already found and read the manual and tomorrow i am going on site to try and install the memory module.

My question was if i can deviate from the recorded memory planning as seen on page 61 of the 5820T owner's manual and install a total of 3 DIMM's of memory (e.g.16GB in DIMM1, 8GB in DIMM2 and 8GB in DIMM4). Although its not seen in the manual, would the system memory still be properly increased or will i have to step on unknown ground?

Thank you for your time and effort.
