Collection: HP Z620 Memory Upgrades

HP Z620 Memory Configuration

The HP Z620 Workstation is a Dual Processor system with 6 DIMM slots per CPU. There are three memory channels per CPU. Each memory channel manages two DIMM slots. Along with standard RDIMM and UDIMM, the Z620 also supports options for standard or low voltage. You cannot mix different memory types. Different speeds can be mixed but the modules will function at the slowest speed installed.

Cloud Ninjas' HP Z620 Workstation Memory Upgrade Tips

• There are a total of 12 DIMM slots on the HP Z620 Workstation server.
• Sizes supported: 2GB, 4GB, 8GB, or 16GB ECC Registered (RDIMM); and 2GB, 4GB or 8GB Unbuffered (UDIMM).
• DO NOT MIX DIFFERENT MEMORY TYPES.
• The HP Z620 Workstation maxes out at 192GB of ECC Registered memory (12 x 16GB). Whereas unbuffered tops out at 96GB (12 x 8GB).
• Depending on the memory configuration and processor model the memory speed may run at 1866MHz, 1600MHz, 1333MHz, or 1066MHz.
• Each processor supports up to 3 channels of DDR3 memory. To realize full performance at least 1 DIMM must be inserted into each channel.
• Think Long Term! Purchase the maximum amount that your HP Z620 Workstation can hold and avoid wasting time and money on modules you won't be able to use if you upgrade again.

Cloud Ninjas' HP HP Z620 Questions & Answers

1. What sizes can you use for the HP Z620 Workstation?
   The HP Z620 Workstation can be upgraded using dual rank 2 GB, 4 GB, 8 GB and 16 GB DIMM. Get your kit at https://cloudninjas.com/.
   
   
2. What speeds are supported by the HP Z620 Workstation?
   The HP Z620 Workstation can support up to 1866 MHz based on DIMM and configuration.
   
   
3. What types of RAM are accepted by the HP Z620 Workstation?
   The HP Z620 Workstation supports DDR3 with ECC or without ECC UDIMM and RDIMM.
   
   
4. What is ECC Registered Memory?
   The HP Z620 Workstation 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 HP Z620 Workstation supports unbuffered memory with ECC and without 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 HP Z620 Workstation 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 HP Z620 Workstation supports the use of unbuffered memory with ECC or without ECC. Mixing unbuffered memory with ECC and non-ECC memory may cause boot failure. The use of both unbuffered and registered memory is not recommended. It is recommended to use identical memory configuration in all channels.
   
   
8. What is max configuration?
   The HP Z620 Workstation allows the maximum configuration of 192 GB using twelve 16 GB RDIMM or up to 96 GB using twelve 8 GB UDIMM. Get your kit at https://cloudninjas.com/.
   
   
9. How many memory channels per CPU?
   The HP Z620 Workstation has a total of 8 sockets which house 4 memory channels at 2 DIMM slots per channel. For a second central processing unit (CPU) there are 4 channels per processor and 1 DIMM socket per channel.
   
   
10. How do I identify the start of the memory channel?
    The HP Z620 Workstation requires that DIMM sockets be populated based on the first black channel and then all white channels. It is recommended to follow the load order recommended the manufacturer based on single or dual processor configuration.
    
    
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.
