Dell PowerEdge R220 Memory Configuration Guide

The Dell PowerEdge R220 is a Single Processor system with 4 DIMM slots. There are two memory channels.  Each memory channel is managing two DIMM slots.  The start of the channel is the white DIMM slot followed by the black DIMM slot.  Different memory speeds can be mixed but the modules will function at the slowest speed installed

Cloud Ninjas' Dell PowerEdge R220 Memory Upgrade Tips

• The Dell PowerEdge R220 has a total of 4 DIMM slots.
• The system supports 1GB, 2GB, 4GB and 8GB ECC Unbuffered (Server UDIMM).
• We recommend matching all modules inside the R220 to ensure stablity.
• Speed options for the PowerEdge R220 are 1066, 1333, 1600 or 1866 MT/s depending on the type of memory configuration.  1866 clocks down to 1600.
• There are 2 memory channels.  There are 2 DIMMs per memory channel. 
• Think Long Term! Purchase the maximum amount that your Dell PowerEdge R220 can hold and avoid wasting time and money on modules you won't be able to use if you upgrade again.
• The total number of memory modules that you should have in your Dell PowerEdge R220 should equal 2 or 4.
• To properly configure your system, install a minimum of two memory modules first.

Cloud Ninjas' Dell PowerEdge R220 Questions & Answers

1. What sizes can you use for the Dell PowerEdge R220 Server?
   The Dell PowerEdge R220 Server can be upgraded using 1 GB, 2 GB, 4 GB, 8 GB DIMM. Buy your memory upgrade kits from Cloud Ninjas.
   
   
2. What speeds are supported by the Dell PowerEdge R220 Server?
   The Dell PowerEdge R220 Server supports 1066, 1333, 1600 or 1866MT/s.  1866 will clock down to 1600.
   
   
3. What types of RAM are accepted by the Dell PowerEdge R220 Server?
   The Dell PowerEdge R220 Server supports DDR3 ECC Unbuffered Server Memory, also know as a Server UDIMM.  No.  Unfortunately ECC Reg (RDIMM) and Load Reduced (LRDIMM) are not compatible with the Dell R220.  Only ECC Unbuffered.
   
   
4. What is ECC Registered Memory?
   The Dell PowerEdge R220 Server does not support registered memory. 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 R220 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 Dell PowerEdge R220 Server does not 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. 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 R220 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 R220 Server allows the maximum configuration is 32 GB with four ECC UDIMMs at size of 8 GB and speed of 1600 MT/s. Its flexible memory configurations accept x4 and x8 based DIMM.  Buy your Dell R220 memory upgrade kit from Cloud Ninjas.
   
   
9. How many memory channels per CPU?
   The Dell PowerEdge R220 Server has 2 channels with 2 slots per channel. For this specific model, DIMM must be installed in each channel.
   
   
10. How do I identify the start of the memory channel?
    The channels are color coded and labeled by Dell to make the process easy.  White is the first DIMM in the channel and black is the second DIMM in the channel.  The Dell PowerEdge R220 Server requires memory to be installed beginning with Channel 1, Socket 1 and are organized in the following manner:
    
    
    • channel 1: memory sockets 1 and 3
    • channel 2: memory sockets 2 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.
