Server ECC Registered DIMM

This OWC module is an 8GB DDR3L 1066 PC3L-8500 CL7 2Rx4 240-pin 1.35V ECC Registered DIMM built for select workstations or servers. It follows JEDEC and RoHS standards and carries a limited lifetime warranty with free technical support. The single stick installs in 240-pin DDR3L slots that require registered ECC memory.

For registered ECC platforms only

It suits administrators upgrading older DDR3L server or workstation boards that explicitly call for registered ECC modules at 1066 MT/s. It will not work in standard desktop computers or consumer laptops that accept only unbuffered non-ECC memory. Builders needing unbuffered ECC or higher-speed DDR3L should look elsewhere.

8GB single-module capacity

The 8GB density handles typical virtualisation hosts, file-serving workloads and legacy database instances that fit within a single DIMM per channel. Headroom disappears when applications demand more than 8GB per slot or require speeds above 1066 MT/s, at which point a platform change becomes necessary.

Questions about this item

Does my server motherboard need 240-pin DDR3L slots to use this module?

Yes, this is a 240-pin DDR3L ECC Registered DIMM, so the motherboard must provide DDR3L slots that accept registered memory.

Can I mix this 1066 MHz CL7 ECC Registered DIMM with existing unbuffered DDR3L modules?

No, registered memory cannot be mixed with unbuffered modules; all installed DIMMs must be ECC Registered for the system to operate correctly.

How can I verify the module is running at PC3L-8500 1066 MHz CL7 after installation?

Check the BIOS or a system information utility; it should report 1066 MHz speed, CL7 latency, 1.35 V voltage and ECC Registered operation.
