Computer memory HP Z640
The workstation-RAM memory expands the memory capacity of HP Z640 by 64GB. The memory module has 288 Pin DIMM and a voltage of 1,2 volt. This memory is 100% compatible to HP Z640.Information on memory configuration
The following technical specifications should be considered in advance:
- The system supports RDIMM and RDIMM 3DS (Registered DIMM) or LRDIMM and LRDIMM 3DS (Load Reduced DIMM) memory modules. Large memory capacities can be realised with LRDIMM 3DS modules.
- RDIMM and RDIMM 3DS memory modules cannot be operated together with LRDIMM and LRDIMM 3DS main memories.
- If a memory expansion is to be made with the already existing RAM memories, it must be checked which basic memory technology (RDIMM / LRDIMM) is available.
- Memory slots without a processor may not be used.
- If memory modules are provided with higher speeds than specified by the system, the memory speed is automatically adjusted to the system specifications.

FAQ - Frequently asked questions about HP Z640
Which capacity does the factory installed memory of the HP Z640 have?
The Z640 is supplied with 64GB RAM.
What is the maximum memory capacity of my HP Z640?
The maximum memory size of the Z640 is 2TB.
The phs memory® option for my HP Z640 is faster than the existing RAM - Is this a problem?
If your system is limited to a slower memory speed, the "Fallback Speed Setting" in the SPD of the phs memory® RAM-Modules ensures the support of slower memory settings down to the given memory speed.
Why is the maximum RAM amount of phs memory® for Z640 higher than the maximum RAM limit listed by HP?
The HP Z640 can be upgrade to a maximum memory capacity of 2TB. This is more than HP has listed in their technical specificatio. There are different reasons, why more memory is possible:
- improved production processes in the memory technology enable higher memory capacities
- new BIOS-Version support higher memory capacities
- the information of the HP datasheet concerning the maximum RAM amount for the Z640 is not up to date.
- we tested and verified the higher memory limit in our overRAMing project.

- improved production processes in the memory technology enable higher memory capacities
- new BIOS-Version support higher memory capacities
- the information of the HP datasheet concerning the maximum RAM amount for the Z640 is not up to date.
- we tested and verified the higher memory limit in our overRAMing project.

Will the legal warranty of the device expire, if I install a new memory module?
The legal warranty right of your Z640 will not be affected if you install the memory yourself.
