Collection: Dell PowerEdge R660xs RAM Memory Upgrades

Dell PowerEdge R660xs Memory RAM configuration

Dell PowerEdge R660xs Server is a dual processor system with 16 DIMM slots on each CPU. There are 4 memory channels per CPU, each managing 1 to 2 channels. The Dell PowerEdge R660xs supports only the new DDR5 ECC Registered memory. Different speeds can be mixed; however the modules will function at the slowest speed installed. If 2 Dimms are used per channel max speed for the R660xs memory will be 4800MT/s, if only 1 dimm used per channel, we can reach 4800MT/s as well. Keep in mind, the CPU you choose also impacts the available speeds your RAM can run.

Cloud Ninjas' Dell PowerEdge R660xs Memory Upgrade Tips

• The total number of DIMMS for the R660xs server is 16 slots.
• The R660xs supports 16GB, 32GB, or 64GB DDR5 ECC DIMMs. The max amount of Registered Memory RAM the Dell R660xs server can hold is 1TB (RDIMM) and it will run at 4800MHz with 2 DIMMs per channel.
• The Dell PowerEdge R660xs server also supports 1 dimm per channel leading up to 1TB, and it will run at 4800MHz.
• The R660xs supports speeds up to 4800MT/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 R660xs 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 R660xs Questions & Answers

1. What sizes can you use for the R660xs?
The PowerEdge R660xs server can be upgraded using 16, 32, 64GB DIMMs. Get your kit at https://cloudninjas.com/


2. What speeds are supported by the Dell PowerEdge R660xs?
The Dell PowerEdge R660xs Server supports RDIMM at 4800MHz.


3. What is ECC Registered Memory?
The Dell PowerEdge R660xs 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 R660xs 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.


5. What is Load Reduced Memory?
The Dell PowerEdge R660xs 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).


6. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory?
The Dell PowerEdge R660xs 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 R660xs?
The Dell PowerEdge R660xs Server supports the standard maximum configuration of 1TB using 16x 64GB RDIMM. Get your kit at https://cloudninjas.com/.


8. How many memory channels per CPU?
The Dell PowerEdge R660xs Server has 4 channels which house 8 sockets per processor with a total of 16 sockets in a dual processor configuration.


9. How do I identify the start of the memory channel?
The Dell PowerEdge R660xs 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?
Orders placed before 8 am are set for same day processing and shipping. Delivery times vary based on carrier and location.


12. What is the warranty on memory for the server?
Cloud Ninjas offers a one-year warranty on fully tested, refurbished memory.


13. 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.
