How to populate dimm slots on DL160G5?

[Tim_273]

Hi forum,

any memory professional over here? I've got a DL160G5 with 4GB memory, 4 modules in slots 1, 3, 5 and 7. These are single rank modules (part no. 398707-051). Now memory must be extended to 16GB, but I'm not sure about how to populate the  slots. Is it ok to populate slots 2 and 4 with 2GB modules and slots 6 and 8 with 4GB modules?

Thanks for a hint,

Stefano

Hi, Stefano

You must follow the guidelines when adding or replacing memory modules:
• For 2P system, both physical processors must be of the same type and speed.
• Use 667 DDR2/4.0 GHz FBD (Fully Buffered DIMM)
• Supported DIMM capacity: 512 MB, 1 GB, 2 GB and 4 GB

• Supported configuration
○ Two DIMMs: Identical model in XMM1 & XMM3
○ Four DIMMs: Identical pair in XMM1/XMM3, and the other identical pair in XMM5/XMM7
○ Eight DIMMs: Identical pair in XMM1/3, XMM5/7, XMM2/4, XMM6/8

The Memories should be installed in pairs and be a match for optimum performance

The DL160 G5 server has eight DIMM slots that support up to 32 GB maximum system memory (4GB in each of the eight DIMM slots).
