Collection: Dell PowerEdge T640 RAM Memory Upgrades

Dell PowerEdge T640 Memory Configuration

The Dell PowerEdge T640 is a Dual Processor system with 12 DIMM slots per CPU. There are four memory channels per CPU. Each memory channel manages three DIMM slots. Along with the standard Registered RDIMM, the Dell PowerEdge T640 also supports options for the Load Reduced LRDIMM. Different speeds can be mixed but the modules will function at the slowest speed installed.

Cloud Ninjas' Dell PowerEdge T640 Memory Upgrade Tips

• The total number of DIMM slots for the Dell PowerEdge T640 is 24.
• The Dell PowerEdge T640 will support 4GB, 8GB, 16GB, 32GB, 64GB or 128GB DDR4 DIMM.
• The Maximum amount of RAM the Dell PowerEdge T640 server can hold is 768 GB of Registered memory (RDIMM).
  
• The Maximum amount of RAM for Load Reduced memory (LRDIMM) is also 3TB.
• 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.
• Think Long Term! Purchase the maximum amount that your Dell PowerEdge T640 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 T640 Questions & Answers

1. What sizes can you use for the Dell PowerEdge T640 Server?
   The Dell PowerEdge T640 Server can support memory modules at speeds of 4GB, 8GB, 16GB, 32GB, 64GB, and 128GB. Get your kit at https://cloudninjas.com/.
   
   
2. What speeds are supported by the Dell PowerEdge T640 Server?
   The Dell PowerEdge T640 Server can 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 T640 Server?
   The Dell PowerEdge T640 Server supports RDIMM and LRDIMM.
   
   
4. What is ECC Registered Memory?
   The Dell PowerEdge T640 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 T640 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 T640 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 T640 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 T640 Server supports the standard maximum configuration of 768 GB using twenty-four 32 GB RDIMM and can be upgraded to 3 TB using twenty-four 128 GB LRDIMM. Get your kit at https://cloudninjas.com/.
   
   
9. How many memory channels per CPU?
   The Dell PowerEdge T640 Server has six channels which house 24 DIMM sockets, 12 DIMM per processor, in a dual processor configuration.
   
   
10. How do I identify the start of the memory channel?
    The Dell PowerEdge T640 Server, requires memory to be installed into the first white channel, then the first black 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?
    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.
