Collection: Dell PowerEdge R740xd RAM Memory Upgrades

Dell PowerEdge R740xd Memory Configuration

The Dell PowerEdge R740XD is a Dual 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 R740XD 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 R740xd Memory Upgrade Tips

• The total number of DIMM for the Dell R740xd is 24 slots.
• The Dell PowerEdge R740XD supports 4GB, 8GB, 16GB, 32GB, 64GB or 128GB DDR4 low profile memory modules.
• The Maximum amount of RAM the PowerEdge R740xd server can hold is 1.5 TB of Registered memory (RDIMM).
• The Dell PowerEdge R740XD also supports load-reduced memory (LRDIMM) up to 3TB.
• 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.  Intel Optane can be mixed with LRDIMMs.
• Think Long Term! Purchase the maximum amount that your Dell PowerEdge R740XD 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 R740xd Questions & Answers

1. What sizes can you use for the Dell PowerEdge R740XD Server?
   The Dell PowerEdge R740XD 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 R740XD Server?
   The Dell PowerEdge R740XD 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 R740XD Server?
   The Dell PowerEdge R740XD Server supports RDIMM and LRDIMM.
   
   
4. What is ECC Registered Memory?
   The Dell PowerEdge R740XD 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 Dell PowerEdge R740XD 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?
   The Dell PowerEdge R740XD 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. 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 R740XD Server does not support the use of both unregistered and registered memory with ECC or the use of non-ECC memory. It is recommended to use identical memory configuration in all channels.
   
   
8. What is max configuration?
   The Dell PowerEdge R740XD Server supports the standard maximum configuration of 1.5 TB using twenty-four 64 GB RDIMM and can be upgraded to 3 TB using twenty-four 128 GB LRDIMM. Get your kit at https://cloudninjas.com/.
   
   
9. How many memory channels per CPU?
   The Dell PowerEdge R740XD Server has six channels which house 12 sockets, per processor with a total of 24 sockets in a dual processor configuration.
   
   
10. How do I identify the start of the memory channel?
    The Dell PowerEdge R740XD 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.
    
    
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?
No. The memory shipped from Cloud Ninjas is compatible with your Dell system. However, it will not have a Dell sticker. We ship major brands such as Samsung, Hynix and Micron.
