Cloud Ninjas' Dell PowerEdge M640 Questions & Answers

1. What sizes can you use for the Dell PowerEdge M640 Server?
   The Dell PowerEdge M640 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 M640 Server?
   The Dell PowerEdge M640 Server support memory modules at speeds of 1866, 2133, 2400, 2666, and 2933 MT/s.
   
   
3. What types of RAM are accepted by the Dell PowerEdge M640 Server?
   The Dell PowerEdge M640 Server supports RDIMM and LRDIMM.
   
   
4. What is ECC Registered Memory?
   The Dell PowerEdge M640 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 M640 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 M640 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 M640 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 M640 Server supports the standard maximum configuration of 512 GB using sixteen 32 GB RDIMM and can be upgraded to 2 TB using sixteen 128 GB LRDIMM. Get your kit at https://cloudninjas.com/.
   
   
9. How many memory channels per CPU?
   The Dell PowerEdge M640 Server has six channels which house 16 sockets, 8 sockets per processor in a dual processor configuration.
   
   
10. How do I identify the start of the memory channel?
    The Dell PowerEdge M640 Server memory must be installed beginning with the sockets marked with white retention levers, then black.
