  • 240-pin 2Rx4 modules install in all 12 Z620 sockets

System-Specific Upgrade for HP Z620

This 16 GB kit contains two 8 GB DDR3L registered ECC DIMMs validated for the HP Compaq Workstation Z620. It targets administrators expanding memory in that specific platform where registered modules are required. Builders using consumer boards or non-ECC platforms cannot use this memory.

Thermals Power and Noise

Operating at 1.35 V, the low-voltage DDR3L modules draw less power and generate less heat than standard 1.5 V DDR3. No heat spreaders are fitted, so airflow across the 240-pin sticks handles cooling silently. Registered buffering adds negligible latency at CL11 11-11-11 timings.

Capacity Jump From Smaller Kits

The Z620 supports up to 96 GB with unbuffered ECC or 192 GB with registered DIMMs across twelve sockets. Adding this 2Rx4 kit moves a workstation from minimal capacity toward those limits. The upgrade is worthwhile when workloads exceed current memory and registered ECC is mandatory.

Perguntas sobre este artigo

How do I install the 240-Pin DDR3L DIMMs into the Z620's 12 sockets without bending the registration notch?

Power off the workstation, open the chassis, align the off-centre notch on each 240-Pin module with the key in the DDR3 slot, press straight down until both retention clips click, then populate sockets in the order shown in the Z620 service guide.

Will the low-voltage 1.35V registered ECC modules need firmware updates or periodic replacement?

The DDR3L 1600 CL11 2Rx4 sticks contain no moving parts or batteries; they require no firmware updates and no scheduled replacement under normal server workloads.

At what point does the registered ECC design hit its throughput ceiling during sustained 1600 MHz operation?

The memory controller on the Z620 caps sustained bandwidth at the PC3L-12800 rate, so the 1600 MHz CL11 registered DIMMs reach their limit when all channels run continuously at that speed.
