  • Capacity32GB (4 x 8GB)
  • Type288-Pin DDR4 SDRAM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Timing17-17-17
  • Voltage1.2V
  • 32 GB total capacity from four 8 GB modules
  • ECC registered design protects data integrity in servers
  • DDR4 2400 speed rated at PC4 19200
  • CL17 timing at 1.2 V for efficient operation
  • Validated for HP Z640 workstation compatibility

Compatibility Confirmed for HP Z640 Workstations

This 32GB kit is built specifically for the HP Compaq Workstation Z640. It delivers four 8GB DDR4 registered DIMMs that the supplier guarantees will function in that platform. The modules operate at 1.2V with a CAS latency of 17.

Suited for ECC Registered Slots Only

The memory is designed for systems that require registered ECC DDR4 modules. It will not work in desktop boards that accept only unbuffered non-ECC memory. Buyers needing standard consumer DIMMs or a different pin count should look at other products.

32GB Total Across Four Channels

The kit provides 32GB of total capacity running at 2400MHz when the installed processor supports that speed. With an 1866MHz capable processor the memory clocks down to 1866MHz. The Z640 platform supports a maximum of 256GB of registered ECC memory.

Questions about this item

Does this 288-pin DDR4 kit require an HP Z640 workstation that supports registered ECC memory?

Yes, the 32 GB kit is built for the HP Z640 and will only function in systems that accept registered ECC DDR4 DIMMs.

If my Z640 has an 1866 MHz capable processor, will these 2400 MHz modules still operate?

The memory will clock down to 1866 MHz to match the processor's maximum supported speed.

How can I verify the kit is running at the correct speed and ECC mode after installation?

Check the BIOS memory information or use a system utility to confirm 2400 MHz operation, CL17 timings, 1.2 V voltage and ECC active status.
