DL320 G6 RAM configuration

I have a new DL320 G6 server that came with a single CPU and two 4Gb RAM modules.  The RAM is installed in slots 3 and 6.  I want to upgrade to at least another 8Gb or 16Gb of RAM but I'm not sure how to populate the slots.  I thought each CPU would only see memory in its channel, which would mean the single CPU installed would only see slots 1-3.  The server (Windows 2008 R2) does register the full 8Gb.  So I'm confused as to what slots are available and how I should go about increasing the RAM.  Any advise is greatly appreciated.

Thanks,

Joe

Hello Joe, 

 

Refer the Hp ProLiant DL360 G6 server QuickSpec document for memory configuration guidelines and slot/capacity/populated speed table: 

 

http://h18004.www1.hp.com/products/quickspecs/13344_div/13344_div.html#Memory

 

Also, refer Core options for memory option part numbers.

Hope the information in usefull. 

 

Thanks and Regards,

Re: DL320 G6 RAM configuration

Thanks for the reply.  I did review those documents before posting.  My confusion relates to how many slots are available in a one CPU system.  The specs state "There are three (3) channels per processor, per server".  Does this mean I can only use slots 1, 4, and 7, or can I make use of all 9 slots with the single CPU?  Sorry if my question is basic.  I've ordered way too many incorrect memory modules in the past and want to make sure I get this correct.

Thanks,

Joe

> The specs state "There are three (3) channels per processor, per server".

 

The very next sentence in the Quickspecs describes the channels: "There are three (3) DIMM slots for each memory channel; nine (9) total slots."

 

1 processor * 3 channels per processor * 3 slots per channel = 9 usable slots. This matches the total number of slots, so all the slots must be usable.

Since a DL320 G6 has only one CPU socket, it would not make sense to have DIMM slots that are unusable with only one CPU.

That's the clarification I was looking for.  I just didn't trust my interpretation.  Thanks for the response.
