Collection: Dell PowerEdge R550 RAM Memory Upgrades

Dell PowerEdge R550 Memory Configuration

The Dell PowerEdge R550 is a Dual Processor system with 8 DIMM slots on each CPU. There are eight memory channels per CPU, each managing one DIMM slot per channel. Along with the standard ECC Registered memory (RDIMM), the Dell PowerEdge R550 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 R550 Memory Upgrade Tips

• The total number of DIMM for the Dell PowerEdge R550 is 16 slots.
• The Dell PowerEdge R550 supports 4GB, 8GB, 16GB, 32GB, 64GB DDR4 ECC DIMM
• The Maximum amount of RAM the Dell PowerEdge R550 server can hold is 1TB of Registered DIMM memory (RDIMM).
• The Dell PowerEdge R550 also supports load-reduced DIMM (LRDIMM) up to 1TB.
• 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 R550 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 R550 Questions & Answers

1. What sizes can you use for the Dell PowerEdge R550 Server?
   The Dell PowerEdge R550 Server can be upgraded using 4, 8, 16, 32, 64 GB DIMM. Get your kit at https://cloudninjas.com/.
   
   
2. What speeds are supported by the Dell PowerEdge R550 Server?
   The Dell PowerEdge R550 Server can support memory modules at speeds of 2666, 2933, and 3200 MT/s.
   
   
3. What types of RAM are accepted by the Dell PowerEdge R550 Server?
   The Dell PowerEdge R550 Server supports RDIMM and LRDIMM.
   
   
4. What is ECC Registered Memory?
   The Dell PowerEdge R550 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 R550 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 R550 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 R550 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 R550 Server supports the standard maximum configuration of 1 TB using sixteen 64 GB RDIMM and can operate with 1 TB using sixteen 64 GB LRDIMM. Get your kit at https://cloudninjas.com/.
   
   
9. How many memory channels per CPU?
   The Dell PowerEdge R550 Server has eight channels per processor which house 8 sockets at 1 DIMM per channel; with a total of 16 sockets in a dual processor system.
   
   
10. How do I identify the start of the memory channel?
    The Dell PowerEdge R550 Server, requires memory to be installed into the first white channel marked A1 for Processor 1, inserting in sequential order 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.
