HP Z220 CMT Workstation Memory Configuration Guide

The HP Z220 CMT Workstation is a Single Processor system with 4 DIMM slots. There are two memory channels which are made up of two DIMM slots. This system does NOT support Low Voltage modules. You cannot mix the different types and speeds of memory. Doing so may cause unwanted issues, so it is best to use matching modules within your system. We put together our upgrade kit with this in mind, making sure we maintain consistency with the modules.

Cloud Ninjas' HP Z220 CMT Memory Upgrade Tips

• The HP Z220 CMT has a total of four DDR3 DIMM slots

Cloud Ninjas' HP Z220 CMT Workstation  Questions & Answers

1. What sizes can you use for the HP Z220 CMT Workstation?
   The HP Z220 CMT Workstation can be upgraded using 2GB, 4GB, and 8GB modules. 
   
   
2. What speeds are supported by the HP Z220 CMT Workstation?
   The HP Z220 CMT Workstation can support memory speeds of 1600MT/s based on DIMM and configuration. 1866MT/s can be installed but will down clock to 1600MT/s
   
   
3. What types of RAM are accepted by the HP Z220 CMT Workstation?
   The HP Z220 CMT Workstation supports DDR3 ECC or non-ECC UDIMMs.
   
   
4. What is ECC Registered Memory?
   ECC memory fixes memory errors within a system. Registered (also called buffered) memory modules register between DRAM modules and the system's memory controller. ECC Registered Memory relieves stress off of the memory controller by lightening the electrical load which makes it more stable and reliable. The HP Z220 Workstation does not support registered memory with ECC.
   
   
5. What is Unbuffered Memory?
   Unbuffered memory has no register between your DRAM and your system’s memory controller. Unbuffered memory can be more efficient than registered memory since it utilizes a direction connection from the DRAM to the memory controller. The HP Z220 Workstation supports unbuffered memory with ECC and without ECC. 
   
   
6. What is Load Reduced Memory?
   Load reduced memory (LRDIMM) 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. The HP Z220 Workstation does not support load reduced memory. 
   
   
7. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory?
   The HP Z220 Workstation supports the use of unbuffered memory with ECC or without ECC. Mixing ECC registered memory with ECC unbuffered or non-ECC memory may cause boot and/or POST failure, system crashed, or even inability to power on your machine. The use of multiple types of memory in one system is not recommended, no matter what types you use. It is always the best option to use identical memory configuration in all channels.
   
   
8. What is max configuration?
   The HP Z220 CMT Workstation allows the maximum configuration of 32 GB using four 8 GB UDIMM with ECC or without ECC.
   
   
9. How many memory channels per CPU?
   The HP Z220 CMT Workstation has a total of 4 slots which are numbered 1 through 4. There is a total of 2 memory channels.
   
   
10. How do I identify the start of the memory channel?
    The HP Z220 Workstation's DIMM slots are colored both white and black. The black slots indicates the start of a memory channel. Each slot is numbered 1 through 4, with slot 1 being furthest from the CPU and slot 4 being closest to the CPU. Slots 1 and 3 are the start of a channel.
    
    
11. Where can I order memory for my workstation?
    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 workstation?
    Cloud Ninjas offers a one-year warranty on fully tested, refurbished memory.
