Two green DDR2 DIMMs with gold contacts 240-pin

IBM

IBM 46C7422 4 GB DDR2-667 ECC DIMM Kit

SKU CH-6E9N-SJT4E

A 4 GB DDR2-667 ECC DIMM kit with two 2 GB modules at 667 MHz, CL5 latency and 1.55 V for BladeCenter and System x servers

  • TypeRAM Module
  • 4 GB kit upgrades BladeCenter and System X servers
  • Dual-rank DDR2-667 modules run at 667 MHz
  • ECC and fully-buffered signal processing protect data integrity
  • Low-power 1.55 V DIMMs reduce energy draw
  • 240-pin DIMM form factor fits standard server slots

Kit capacity and fit

This IBM 46C7422 kit supplies 4 GB of memory as two 2 GB DIMMs for BladeCenter and System x servers. The modules are built for platforms that require fully buffered ECC DDR2-667 registered memory. Buyers who need higher-density modules or a different pin count should verify their system documentation first.

Sustained operation

Low-power DDR3 components run at 1.55 V to reduce thermal load inside dense blade chassis. Dual-rank organisation and CL5 latency at 667 MHz deliver steady throughput for virtualisation workloads that keep memory busy for long periods. The fully buffered interface helps maintain signal integrity across extended sessions.

Build and connectors

Each module uses a 240-pin DIMM form factor keyed for PC2-5300 slots. ECC circuitry detects and corrects single-bit errors to protect data integrity in mission-critical deployments. Installers should confirm the server supports fully buffered DIMMs before seating the modules.

Questions about this item

How much power does the 1.55 V DDR2-667 kit draw when the server runs continuously?

Each 2 GB module operates at 1.55 V, and the low-power design reduces heat output during all-day workloads.

Which server slots accept the 240-pin ECC DIMMs in this 4 GB kit?

The 240-pin fully buffered DIMMs fit BladeCenter and System x slots that support PC2-5300 registered memory.

Can the DDR2-667 CL5 modules share a channel with DDR3 DIMMs already installed?

No, DDR2 and DDR3 use different pinouts and voltages, so they cannot be mixed in the same system.
