Cloud Ninjas' HPE ProLiant XW9400 Questions & Answers

  1. What sizes can you use for the HPE ProLiant XW9400 Server?
    The HPE ProLiant XW9400 can be upgraded using 1GB, 2GB, 4GB, and 8GB DIMM modules. Get your kit at https://cloudninjas.com/.

  2. What speeds are supported by the HPE ProLiant XW9400 Server?
    The HPE ProLiant XW9400 Server can support up to 667MT/s.

  3. What types of RAM are accepted by the HPE ProLiant XW9400 Server?
    The HPE ProLiant XW9400 Server supports RDIMM.

  4. What is ECC Registered Memory?
    The HPE ProLiant XW9400 Server does support 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 HPE ProLiant XW9400 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 HPE ProLiant XW9400 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.

  7. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory?
    The HPE ProLiant XW9400 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 HPE ProLiant XW9400 Server allows the standard maximum configuration of 16 GB using 4x 4GB UDIMM. Get your kit at https://cloudninjas.com/.

  9. How many memory channels per CPU?
    The HPE ProLiant XW9400 Server has 2 channels which house 2 DIMM slots per processor. There are 2 DIMM slots per channel.

  10. How do I identify the start of the memory channel?
    The HPE ProLiant XW9400 Server requires that DIMM sockets be populated beginning with the first white 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.
