8 GB DDR2 667 ECC Registered kit

This 8 GB kit contains two 4 GB modules built to the DDR2 667 (PC2 5300) standard. It targets administrators maintaining IBM systems that require registered ECC memory. The modules operate at 1.80 V with a CAS latency of CL5.

Capacity and headroom for legacy workloads

Eight gigabytes provides sufficient space for typical server operating systems and moderate database tasks on supported platforms. Workloads that exceed this limit will encounter swapping or allocation failures because the kit cannot be expanded beyond the supplied modules.

Thermals noise and power draw in normal use

Registered DDR2 modules run at the standard 1.80 V, producing modest heat that is handled by ordinary server airflow. No active cooling is included, so the system chassis fans must maintain adequate circulation. Acoustic output is negligible compared with other server components.

商品問答

Will these DDR2 667 registered modules work in my older DDR2 system that currently uses unbuffered memory?

No. Registered modules require a motherboard designed for registered memory; they cannot be mixed with unbuffered modules and will not function in a standard desktop board.

How can I verify the kit is running at the correct 667 MHz speed and CL5 latency after installation?

Enter the system BIOS or use a utility such as CPU-Z; the memory tab should show DDR2 667 (PC2 5300) with a CAS latency of 5.

What exactly ships in the box and is anything else required to use the 8 GB kit?

The package contains two 4 GB 240-pin DDR2 SDRAM modules; no additional parts are needed if your IBM system supports registered ECC DDR2 667 memory.
