Collection: Dell PowerEdge R730xd XL RAM Memory Upgrades

Dell PowerEdge R730xd XL Memory Configuration

The R730xd XL is a Dual Processor system with 12 DIMM slots per CPU. There are four memory channels per CPU. Each memory channel manages three DIMM slots. Along with the standard Registered RDIMMs, the R730xd XL also supports options for the Load Reduced LRDIMMS. Different speeds can be mixed but the modules will function at the slowest speed installed.

Cloud Ninjas' Dell PowerEdge R730xd XL Memory Upgrade Tips

• The total number of DIMM slots for the R730xd XL is 24.
• The PowerEdge R730xd XL will support 4GB, 8GB, 16GB, 32GB or 64GB DDR4 Registered.
• This server will also support 32GB or 64GB Load Reduced Modules (LRDIMM).
• The Maximum amount of RAM the PowerEdge R730xd XL server can hold is 1.5TB (24 x 64GB) of Registered DIMMs (RDIMMs) memory.
• The Maximum amount of RAM for Load Reduced memory (LRDIMMs) is also 1.5TB.
• When purchasing new memory it is best to purchase identical memory modules to what your system already has. Your current server configuration will determine the supported DIMM type and speed.
• The PowerEdge R730xd XL runs on 2133MHz or 2400MHz memory.
• Think Long Term! Purchase the maximum amount that your PowerEdge R730xd XL can hold and avoid wasting time and money on modules you won't be able to use if you upgrade again.

Cloud Ninjas' Dell PowerEdge R730xd XL Questions & Answers

1. What sizes can you use for the Dell PowerEdge R730xd XL Server?
   This is a slightly tricky question.  DIMM sizes for the Dell PowerEdge R730xd XL server varies depending on type of memory.  RDIMMs can be upgraded using 4GB, 8GB, 16GB or 32GB modules.  LRDIMMs can be upgrades with 16GB, 32GB, 64GB or 128GB DIMMs. Buy your memory kits from Cloud Ninjas.
   
   
2. What speeds are supported by the Dell PowerEdge R730xd XL Server?
   The Dell PowerEdge R730xd XL server can support memory modules at speeds of 2133, 2400 and 2666MT/s.  Please know in advance, that 2666 DIMM will clock down to a speed of 2400MT/s, which is the top speed for the R730xd server.
   
   
3. What types of RAM are accepted by the Dell PowerEdge R730xd XL Server?
   The Dell PowerEdge R730xd XL server supports two main types of memory.  ECC Registered, also called RDIMM, and Load Reduced memory, also called LRDIMM.  ECC Unbuffered is not supported.  DDR4 only.
   
   
4. What is ECC Registered Memory?  Does the R730xd support RDIMMs?
   Yes.  The Dell PowerEdge R730xd XL server supports registered memory with ECC. ECC memory detects and corrects memory errors within the server environment. Registered (also called buffered) memory modules register between DRAM modules and the system's memory controller. ECC Registered Memory transfers less electrical load to your memory controller which makes it more stable and reliable.
   
   
5. What is ECC Unbuffered Memory?  Will my R730xd XL work with ECC UDIMMs?
   No.  The Dell PowerEdge R730xd XL server does not support unbuffered memory with ECC. Unbuffered memory is memory that has no register between your DRAM and your system’s memory controller.
   
   
6. What is Load Reduced Memory?  Are LRDIMMs supported by the R730xd?
   Yes.  The Dell PowerEdge R730xd XL server does support load reduced DIMM (LRDIMM). Load reduced DIMM is designed with a buffer chip (or chips) to replace the register to help minimize loading, the LRDIMM increases server system memory capacity and speed. Hyper-cloud DIMM (HCDIMM or HDIMM) is considered load reduced memory which is 240-pin, 72 bit wide. 
   
   
7. Can I mix ECC Reg with Load Reduced memory?
   Negative.  You cannot mix different types of memory.  The Dell PowerEdge R730xd server does not support the use of both load reducing and ECC registered memory at the same time. It is recommended to use identical memory modules across the entire system.
   
   
8. What is max memory configuration for my Dell R730xd XL server?
   The answer is different depending upon the type of RAM you use.  The Dell PowerEdge R730xd XL server supports RDIMMs and LRDIMMs.  ECC Reg will max out at 768GB using twenty-four 32GB 2400MT/s modules.  Whereas load reduced can be upgraded to 3TB using twenty-four 128 GB DDR4 2400MT/s LRDIMMs.  Buy your kits from Cloud Ninjas.
   
   
9. How many memory channels does my PowerEdge R730xd XL have?
   Good question.  There are 24 DIMM across 2 processors inside the Dell R730xd XL server.  This equates to 12 DIMM per processor.  Each processor supports 4 memory channels.  Each memory channel controls 3 DIMM slots, which is where you see the white, black, green color coding come in.
   
   
10. How do I identify the start of the memory channel on the Dell R730xd XL motherboard?
    The Dell PowerEdge R730xd XL Server, requires memory to be installed into the first white channel marked A1 for Processor 1 and then Processor 2 the first white channel marked B1.  White is the first DIMM in a channel.  Black is the second DIMM in a channel.  And green is the third DIMM in a channel.  A is the first channel.  B is the second channel and so forth.  To maximize speed and performance, always install your DIMMs in the start of each channel (white slot).
