Dell PowerEdge R730 Server Memory Spec Overview & Upgrade Tips | How to Configure the System

The Dell PowerEdge R730 is a 2U powerhouse server. This video will provide a general system overview and tutorial on how to configure & install the memory properly. Dell R730’s are operated by 2 x Intel E5-2600 V3 or V4 series CPUs (LGA2011-3 socket). The R730 is a Dell 13th Generation server, which is the next gen to the popular Dell PowerEdge R720 server. There are 24 DIMM slots utilizing DDR4 memory modules. There are two types of memory to configure your R730 server with: ECC Registered (RDIMM) and Load Reduced (LRDIMM). With ECC Reg, the max configuration is 768GB via (24 x 32GB) DDR4 PC4-21300V-R 2666MHz Server Memory. However, load reduced DIMMs will provide four times the max capacity with 3TB of RAM via (24 x 128GB) DDR4 PC4-21300V-L 2666MHz Server Memory. For this reason, Cloud Ninjas' recommends LRDIMMs over RDIMMs. More scalability with load reduced. Each CPU controls 12 DIMM slots. There are 4 Memory Channels per CPU. Which means there are 3 DIMMs per Memory Channel. Dell has color coded each DIMM slot so you know how to properly load your memory. White is the start of each memory channel. The proper configuration for 2 CPUs would be 8, 16 or 24 DIMMs. In this video, we will discuss in more depth how to actually load the DIMMs inside your PowerEdge R730 server.

2 things of note:
1. Xeon v3 memory speed is 2133 and Xeon v4 is 2400 (budget SKUs are slower). So DDR4-2666 doesn't provide any benefits.
2. Those speeds are only achieved on a 8 DIMM configuration. With 16 or 24 DIMMS it will run slower.
A v4 with 2400 memory speed will run at 2133 with 16 modules and 1866 with 24 modules.

How to know what type of memory (RDIMM or LRDIMM) is installed on server ?

[garystreit]

I have a R730XD and 8 PC4-2400T ECC 32GB RAM Modules, in what slots should the memory be installed to achieve the best performance with Dual Xeon E5-2666 v3 10Core @ 2.9Ghz?

I already have 64GB (4x16GB). I ordered 2 more 16GB DIMM's. What's the best layout for adding 2 more sticks?
