Server DDR3 Upgrade

This 32 GB DDR3 ECC registered RDIMM is built for workstations and servers that require registered memory. It will not work in standard desktop computers and cannot be mixed with unbuffered modules. Buyers who need memory for a consumer motherboard or a laptop should look elsewhere.

DDR3 1333 Interface Limits

The module runs at 1333 MT/s with CL9 latency on a 240-pin DDR3 interface at 1.5 V. That bus speed and voltage are fixed by the DDR3 standard, so the memory cannot operate faster or at a lower voltage than specified. Systems that demand a higher data rate or a different DDR generation will not be compatible.

4Rx4 Rank Configuration

The 4Rx4 organization is the single specification that decides whether this DIMM fits a given server platform. Memory controllers that do not support quad-rank x4 modules will not recognise the capacity. Verify the motherboard's qualified-vendor list for 4Rx4 support before purchasing.

Questions about this item

Should I choose the 32GB DDR3 1333 PC3-10600 CL9 4Rx4 240-pin 1.5V ECC Registered RDIMM or a different capacity?

This module provides 32GB in a single 240-pin DDR3 ECC RDIMM. Select it when your server or workstation requires a 32GB registered DIMM at 1333 MT/s with CL9 latency and 4Rx4 organisation.

What does the 1333 MT/s speed mean once the module is installed in a real server?

The memory will run at up to 1333 MT/s (PC3-10600) with CL9 timing, delivering the bandwidth and latency specified by the JEDEC DDR3 1333 standard for registered ECC DIMMs.

How does the 240-pin DDR3 registered ECC interface limit what I can do with this RAM?

The 240-pin DDR3 registered ECC form factor fits only server and workstation boards that support registered ECC DDR3; it cannot be used in standard desktop systems or mixed with unbuffered memory.
