Collection: Dell PowerEdge MX840c RAM Memory Upgrades

Dell PowerEdge MX840c Memory RAM configuration

Dell PowerEdge MX840c Server is a Dual processor system with 48 DIMM slots on each CPU. There are 24 memory channels per CPU, each managing 2 DIMM slots. Along with the standard ECC Registered (RDIMM) memory, the MX840c supports options for Load Reduced (LRDIMM) memory. Different speeds can be mixed; however the modules will function at the slowest speed installed.

Cloud Ninjas' Dell PowerEdge MX840c Memory Upgrade Tips

• The total number of DIMMS for the MX840c server is 48 slots.
• The MX840c supports 8GB, 16GB, 32GB, 64GB or 128GB DDR4 ECC DIMM. The max amount of RAM the Dell MX840c server can hold is 1.5TB of Registered memory (RDIMM).
• The Dell PowerEdge MX840c server also supports load-reduced (LRDIMM) up to 6TB.
• The MX840c supports speeds up to 2666 MT/s.
• When purchasing new memory it is best to purchase identical memory modules to what your system already has. Your current server system 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 MX840c 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 Questions & Answers

1. What sizes can you use for the MX840c?
The PowerEdge MX840c server can be upgraded using 8, 16, 32, 64, and 128 GB DIMM. Get your kit at https://cloudninjas.com/


2. What speeds are supported by the Dell PowerEdge MX840c?
The Dell PowerEdge MX840c Server supports RDIMM and LRDIMM.


3. What is ECC Registered Memory?
The Dell PowerEdge MX840c 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


4. What is Unbuffered memory?
The MX840c Server supports unbuffered memory with ECC. Unbuffered memory is memory that has no register between your DRAM and your system's memory controller.


5. What is Load Reduced Memory?
The MX840c 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).


6. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory?
he Dell PowerEdge MX840c 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.


7. What is Max Configuration for the MX840c?
The Dell PowerEdge MX840c Server supports the standard maximum configuration of 1.5 TB using 24x 64GB RDIMM and can be upgraded to 6 TB using 48x 128GB LRDIMM. Get your kit at https://cloudninjas.com/.


8. How many memory channels per CPU?
The Dell PowerEdge MX840c Server has 24 channels which house 48 sockets, per processor with a total of 48 sockets in a dual processor configuration.


9. How do I identify the start of the memory channel?
The Dell PowerEdge MX840c Server, requires memory to be installed into the first white channel marked A1 for Processor 1 and then Processor 2.


10. 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.


11. How soon will my RAM arrive?
