Collection: Dell PowerEdge R540 RAM Memory Upgrades

Dell PowerEdge R540 Memory Configuration

The Dell PowerEdge R540 is a Dual Processor system with 8 DIMM slots on each CPU. There are four memory channels per CPU, each managing 2 DIMM slots. Along with the standard ECC Registered (RDIMM) memory, the Dell PowerEdge R540 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 R540 Memory Upgrade Tips

• The total number of DIMM for the Dell PowerEdge R540 is 16 slots.
• The Dell PowerEdge R540 support 4GB, 8GB, 16GB, 32GB, or 64GB DDR4 ECC Registered. The Maximum amount of RAM the PowerEdge R540 server can hold is 1TB of Registered DIMM (RDIMM) memory.
• The Dell PowerEdge R540 also supports load-reduced DIMM (LRDIMM) up to 128GB modules with max capacity of 1.5TB of memory.
• 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 PowerEdge R540 can hold and avoid wasting time and money on modules you won't be able to use if you upgrade again.

2. What speeds are supported by the Dell PowerEdge R540 Server?
   The Dell PowerEdge R540 Server can support memory modules at speeds of 1866, 2133, 2400, 2666, 2933 and 3200 MT/s. 2933MT/s and 3200MT/s modules will clockdown to 2666MT/s.
   
   
3. What types of RAM are accepted by the Dell PowerEdge R540 Server?
   The Dell PowerEdge R540 Server supports RDIMM and LRDIMM.
   
   
4. What is ECC Registered Memory?
   The Dell PowerEdge R540 Server supports registered memory with ECC.ECC Registered Memory detects and corrects single-bit errors in memory using parity bits and a series of mathematical equations. In ECC Registered memory, Registers (also called buffers) sit between the memory module’s address bus and the physical memory chips.
   
   
5. What is Unbuffered Memory?
   The Dell PowerEdge R540 Server does not support unbuffered memory with ECC. Unbuffered memory is memory that has no registers (also called buffers). Unbuffered memory can be ECC (for entry-level servers and workstations) or Non-ECC (for desktops and laptops).
   
   
6. What is Load Reduced Memory?
   The Dell PowerEdge R540 Server does support load reduced DIMM (LRDIMM). ECC Load Reduced Memory detects and corrects single-bit errors in memory using parity bits and a series of mathematical equations and reduces electrical load on the system’s memory controller when compared to other types of memory modules. In ECC Load Reduced memory, Registers (also called buffers) sit between the memory module’s address bus and the physical memory chips. Additional registers also sit between the Memory chips and the data bus, further reducing load on the system’s memory controller in comparison to ECC registered memory.
   
   
7. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory?
   The Dell PowerEdge R540 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 R540 Server supports the standard maximum configuration of 1024 GB using sixteen 64 GB dual rank RDIMM and can be upgraded to 1536 GB using sixteen 128 GB quad rank LRDIMM. Get your kit at https://cloudninjas.com/.
   
   
9. How many memory channels per CPU?
   The Dell PowerEdge R540 Server has 6 memory channels per processor. Processor 1 has 10 memory sockets; two white channels support 2 DIMM per channel and two black channels which support 1 DIMM per channel. Processor 2 has six memory sockets, each support 1 DIMM per channel.
   
   
10. How do I identify the start of the memory channel?
    The Dell PowerEdge R540 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. Consult your Dell PowerEdge R540 Server hardware manual for a diagram of memory channel.
    
    
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?
    Shipping may take up to eight weeks based on stock availability and shipping 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.
