Collection: Dell PowerEdge R940xa RAM Memory Upgrades

Dell PowerEdge R940xa Memory Configuration

The Dell PowerEdge R940xa Server is a Quad Processor system with 12 DIMM slots on each CPU. There are four memory channels per CPU, each managing three DIMM slots. Along with the standard ECC Registered (RDIMM) memory, the Dell PowerEdge R940xa Server supports options for Load Reduced (LRDIMM) memory. Different speeds can be mixed but the modules will function at the slowest speed installed.

Cloud Ninjas' Dell PowerEdge R940xa Memory Upgrade Tips

• The total number of DIMM for the Dell R940xa is 48 slots.
• The Dell PowerEdge R940xa Server supports 4GB, 8GB, 16GB, 32GB, 64GB or 128GB DDR4 ECC DIMM. The Maximum amount of RAM the Dell PowerEdge R940xa  server can hold is 6TB of Registered memory (RDIMM).
• The Dell PowerEdge R940xa Server also supports load-reduced (LRDIMM) up to 6TB.
• 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.
  
• RDIMM and LRDIMM must not be mixed.
• Think Long Term! Purchase the maximum amount that your Dell PowerEdge R940xa Server 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 R940xa Questions & Answers

1. What sizes can you use for the Dell PowerEdge R940xa Server?
   The Dell PowerEdge R940xa Server can be upgraded using 4, 8, 16, 32, 64, and 128 GB DIMM. Get your kit at https://cloudninjas.com/.
   
   
2. What speeds are supported by the Dell PowerEdge R940xa Server?
   The Dell PowerEdge R940xa Server can support memory modules at speeds of 1866, 2133, 2400, 2666, 2933 and 3200 MT/s.
   
   
3. What types of RAM are accepted by the Dell PowerEdge R940xa Server?
   The Dell PowerEdge R940xa Server supports RDIMM and LRDIMM.
   
   
4. What is ECC Registered Memory?
   The Dell PowerEdge R940xa 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 Unbuffered Memory?
   The R940xa Server supports 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?
   The R940xa Server supports 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. LRDIMM differs from low capacity, low voltage registered memory modules (LV RDIMM).
   
   
7. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory?
   The Dell PowerEdge R940xa 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.
   
   
8. What is max configuration?
   The Dell PowerEdge R940xa Server supports the standard maximum configuration of 3 TB using forty-eight 32 GB RDIMM and can be upgraded to 12 TB using forty-eight 128 GB LRDIMM. Get your kit at https://cloudninjas.com/.
   
   
9. How many memory channels per CPU?
   The Dell PowerEdge R940xa Server has six channels which house 12 sockets, per processor with a total of 48 sockets in a quad processor configuration.
   
   
10. How do I identify the start of the memory channel?
    The Dell PowerEdge R940xa Server, requires memory to be installed into the first white channel marked A1 for Processor 1 and then Processor 2, 3, and 4.
    
    
11. Where can I order memory for my server?
    Order your memory at https://cloudninjas.com/ by finding and selecting the memory package that is right for you.
    
    
12. How soon will my RAM arrive?
    Orders placed before 8 am are set for same day processing and shipping. Delivery times vary based on carrier and location.
    
    
13. What is the warranty on memory for the server?
    Cloud Ninjas offers a one-year warranty on fully tested, refurbished memory.
    
    
14. Is this RAM Dell labeled or Dell branded?
