HP Workstations FAQs

FAQ | HP Desktop Workstation FAQs
What are the memory capacity dierences between the products?
• HP Z440: Up to 128 GB (8 x 16 GB)
• HP Z640: Up to 256 GB (8 x 32 GB)
• Requires 2 CPUs
• HP Z840 : Up to 512 GB (16 x 32 GB)
• Available at launch
• Requires 2 CPUs
• Planning to add larger capacities after launch
What are the advantages of DDR4 memory?
• DDR4 memory is moving at 2133 MHz, up from 1866 MHz on DDR3, so potentially, when the system is running at max
capacity, the user could see an increase of up to 14% in speed and higher performance.
Why should a customer transition to DDR4 memory?
• New platforms only support DDR4 memory, so for this transition, it is necessary.
Why is DDR4 memory more expensive?
• DDR4 memory is a new technology, so its application in computer systems is still relatively low, making it more
expensive to produce in lower volumes.
Will DDR4 memory work in the old HP Zx20 systems?
• No, the HP Zx20 systems support only DDR3 memory. DDR3 and DDR4 memory types cannot be intermixed or
installed into systems in which they are not supported.
Will DDR3 memory work in the new HP Zx40 systems?
• No, users will have to transition to DDR4 for the new Zx40 series of HP Workstations.

add in card. The new chassis design provides an integrated front
handle and is smaller than 4U to increase space for rack mounting. In comparison, the Z440 is more user friendly and
faster with all the same features that made the Z420 a well-loved machine.
