Server Memory for System X

This 8 GB DDR3 module is built for IBM System X servers that require registered ECC memory. It suits administrators maintaining or expanding existing DDR3 platforms where error correction and signal buffering are mandatory. The part is sold in refurbished condition.

240-Pin DDR3 Installation

The stick fits standard 240-pin DDR3 DIMM slots and registers each address cycle to reduce electrical load on the memory controller. ECC and registered operation must be supported by the server board; mixing registered and unbuffered modules will prevent the system from posting. Verify the platform accepts 4Rx8 organisation before fitting.

1066 MHz CL7 Registered ECC

Rated at DDR3 1066 (PC3 8500) with CAS latency 7, this 4Rx8 module delivers the bandwidth and error correction required by compatible System X configurations. Buyers who need higher frequencies, lower latency or unbuffered memory should select a different specification.

Questions about this item

How can I confirm the 8GB DDR3 1066 module is running at CL7 with ECC registered after installation?

Enter the server BIOS or use a hardware utility to verify the memory speed shows 1066 MT/s, CAS latency reads CL7, and ECC plus registered status are both reported as enabled for the installed module.

What ships with the 46C7476 module and what must I source separately?

The package contains the single 240-pin DDR3 SDRAM DIMM; any additional memory modules, riser cards or installation tools required for your System X server must be purchased separately.

Which capacity and speed version should I choose for a System X server needing PC3 8500 registered ECC memory?

Select the 8GB DDR3 1066 (PC3 8500) CL7 4Rx8 registered ECC module, matching the exact specification required by the server memory slots.
