16GB DDR4 2666MHz CL19 unbuffered DIMM for HP Z1 G5 and Z2 G4 workstations

  • Capacity16GB
  • Type288-Pin DDR4 SDRAM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Timing19-19-19
  • Voltage1.20V
  • 16 GB capacity adds headroom for heavy workloads
  • 2666 MHz DDR4 speed matches supported platform spec
  • CL19 timing keeps latency low at rated frequency
  • 2 V operation reduces power draw and heat
  • validated for HP Z1 G5 and Z2 G4 workstations

HP Workstation Compatible DDR4 Upgrade

This 16GB DDR4 DIMM is built for HP Z1 G5, Z2 SFF G4 and Z2 Tower G4 workstations that require non-ECC memory. It installs as a single 288-pin module running at 2666MHz with CL19 timing and 1.20V operation.

DDR4 2666MHz Interface Limits

The DDR4 2666 standard caps transfer rates at 21300 MT/s, so this module cannot exceed that ceiling. Mixing it with slower DDR4 will force all memory to run at the lowest installed speed, and the platform tops out at four populated sockets.

16GB Module Within 64GB Maximum

A single 16GB stick leaves three slots open on the four-socket platform, allowing expansion up to the 64GB system limit. Buyers who want more storage than 64GB total or who need ECC error correction cannot use this non-ECC kit.

Kysymyksiä tästä tuotteesta

Should I choose the single 16 GB DIMM or look for a matched pair kit for my HP Z2 G4?

The product is sold as one 16 GB stick; to maximise performance the manufacturer recommends installing modules in matched pairs, so a two-stick kit would be preferable if you have free slots.

What does the 2666 MHz rating mean once the module is installed in a Z1 G5?

The memory will run at up to 2666 MHz, but the system will operate at the slowest speed among all installed modules or the processor's memory controller limit.

Is the 288-pin DDR4 interface compatible with the four DIMM slots in my Z2 Tower G4?

Yes, the 288-pin DDR4 DIMM fits the four slots on that platform and the board supports a maximum of 64 GB total.
