Collection: HP Z1 RAM Memory Upgrades

HP Z1 Memory Configuration Guide

The Z1 is a Single Processor system with 4 DIMM slots. There are two memory channels each managing two DIMM slots. This system only supports 2GB, 4GB, 8GB ECC unbuffered modules as well as 2GB UDIMM modules. You can install modules with different speeds into your system, but they will run on the lowest speed installed. It is always best practice to install DIMMs with matching speeds for the best performance and reliability.

Cloud Ninjas' HP Z1 Workstation Memory Upgrade Tips

• There are a total of four DDR3 DIMM slots on the HP Z1
  
• Supports ECC Unbuffered and Non-ECC DDR3 modules
• Speeds Supported: 1066MHz, 1333MHz,1600MHz and 1866MHz. 1866MHz will clock down to 1600MHz.
• The system supports 2GB, 4GB and 8GB ECC unbuffered or 2GB UDIMMs
• DO NOT MIX DIFFERENT MEMORY TYPES
• Maximum of 32GB ECC modules or 8GB Non-ECC Modules
• There is one CPU with two channels each containing two DIMM slots
• Think Long Term! Purchase the maximum amount that your HP Z1 can hold and avoid wasting time and money on modules you wont be able to use if you upgrade again.

Cloud Ninjas' HP HP Z1 Workstation Questions & Answers

1. What memory sizes can you use for the HP Z1 Workstation?
   The HP Z1 Workstation accepts 2GB, 4GB, and 8GB ECC unbuffered and 2GB non-ECC unbuffered memory modules.
   
   
2. What speeds are supported by the HP Z1 Workstation?
   The HP Z1 Workstation can support 1066MHz,1333MHz, 1600MHz, and 1866MHz based on DIMM and configuration. 1866MHz modules will be clocked down to run at 1600MHz.
   
   
3. What types of RAM are accepted by the HP Z1 Workstation?
   The HP Z1 Workstation supports DDR3 ECC and non-ECC UDIMMs.
   
   
4. What is ECC Registered Memory?
   ECC memory can detect and correct memory errors which is useful in environments where protection against data corruption is crucial. 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. When it comes to the HP Z1 Workstation, ECC registered memory is not supported, however ECC unbuffered is.
   
   
5. What is Unbuffered Memory?
   Unbuffered memory is memory that has no register between your DRAM and your system’s memory controller. Unbuffered memory, also known as a UDIMM, is used in regular desktops and laptops. The HP Z1 Workstation supports unbuffered memory; however, it is not considered to be a regular desktop. The Z1 supports ECC unbuffered memory (ECC UDIMM) as well, which is the same as normal unbuffered memory, but has ECC capabilities. Therefore, the HP Z1 can be thought of as a desktop that supports unbuffered server memory.
   
   
6. What is Load Reduced Memory?
   Load reduced DIMMs are designed with a buffer chip (or chips) to replace the register to help minimize the load on a server’s memory bus. the LRDIMM increases server system memory capacity and speed. The HP Z1 Workstation does not support load reduced DIMMs (LRDIMM).
   
   
7. Can I mix ECC Reg with ECC unbuffered or Non-ECC memory?
   The use of both unbuffered and registered memory is not recommended. Mixing memory types may cause boot failure and other issues. It is always recommended to use identical memory configuration in all channels. The HP Z1 Workstation supports the use of unbuffered memory with ECC or without ECC, but not interchangeably.
   
   
8. What is max configuration?
   The HP Z1 Workstation allows for the maximum memory configuration of 4x8GB PC3-12800e (32 GB) or 4x2GB PC3-12800U (8 GB). Get your kit at Cloud Ninjas.
   
   
9. How many memory channels per CPU?
   The HP Z1 Workstation has a total of 4 slots which are numbered 1 through 4. There is a total of 2 memory channels with 2 DIMM slots total. DIMMs that are electrically and thermally compatible with this model are recommended.
   
   
10. How do I identify the start of the memory channel?
    The HP Z1 Workstation requires that DIMM sockets only be populated based on the exact number of slots i.e., 1 through 4.
    
    
11. Where can I order memory for my workstation?
    Order your memory at Cloud Ninjas 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.
