Computer Memory Solutions CM20487212800ECCR2R4H 32GB (2x16GB) DDR3 1600MHz ECC Registered DIMM memory upgrade

SKU CH-JGH6-3GV0S

A 32 GB kit of two 16 GB DDR3 1600 MHz ECC registered DIMMs for HP Z620 workstations

  • Capacity32GB (2 x 16GB)
  • Type240-Pin DDR3 SDRAM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Timing11-11-11
  • Voltage1.5V
  • ECC registered design protects data integrity in server workloads
  • 32GB dual-channel kit expands Z620 memory to 96GB maximum
  • DDR3 1600MHz CL11 timing matches supported system speeds
  • 5V 240-pin DIMMs install directly into 12 expansion sockets
  • 2Rx4 registered modules maintain signal quality across full capacity

Compatible HP Z620 memory upgrade

This 32GB kit contains two 16GB DDR3 registered ECC DIMMs built for the HP Compaq Workstation Z620. Each module runs at 1600MHz with CL11 timing at 1.5V. The 2Rx4 organisation and registered buffer suit the workstation's quad-channel architecture. Buyers who need unbuffered ECC or non-ECC memory for other platforms cannot use this kit.

240-pin registered DIMM build

The modules use a standard 240-pin DDR3 form factor without a heat spreader. Registered signalling reduces electrical load on the memory controller when all twelve DIMM sockets are populated. Mixing these registered DIMMs with unbuffered ECC modules is not supported by the Z620, so a full upgrade must use matching registered parts. Systems that require low-profile modules or passive cooling clearance should verify fit before purchase.

DDR3 1600MHz speed limit

The Z620 platform supports 1066MHz, 1333MHz, 1600MHz and 1866MHz speeds depending on the installed processor. This kit operates at the 1600MHz (PC3-12800) rate; 1866MHz operation requires E5-2600 v2 or E5-1600 v2 series processors, which are not referenced in the kit specifications. Maximum registered ECC capacity is 192GB across twelve sockets, so this 32GB kit leaves room for further expansion.

Questions sur cet article

What does the PC3-12800 rating mean for this DDR3 memory?

PC3-12800 denotes DDR3-1600 operation at CL11 11-11-11 timing with 1.5V voltage.

Will these 240-pin DIMMs fit the HP Z620 workstation?

Yes, the 240-pin DDR3 registered ECC modules are built for the Z620's 12 DIMM sockets.

How do I install the two 16GB sticks for quad-channel performance?

Populate four matching modules per bank; with this 2x16GB kit add a second identical kit to fill a bank of four.
