64 GB DDR3-1066 registered kit

This kit provides 64 GB of DDR3-1066 memory using two 32 GB registered DIMMs. It is built for servers that require ECC error correction and registered signal processing. The modules run at 1.35 V with a CAS latency of CL9. They use the standard 240-pin form factor.

Suited for DDR3 servers needing ECC registered DIMMs

Systems that accept DDR3 registered ECC modules at 1066 MHz can use this kit. It will not work in platforms that require unbuffered non-ECC memory or a different DDR generation. Builders needing higher frequencies or lower voltages should look elsewhere.

1066 MHz DDR3 speed (PC3-8500)

The memory operates at 1066 MHz, rated as PC3-8500. This speed determines whether the modules match the server's memory bus. Verify the platform supports DDR3-1066 registered ECC before purchase.

Questions about this item

Does my server need 240-pin DDR3 slots and support for 1.35 V registered ECC DIMMs to use this kit?

Yes, each module is a 240-pin DDR3 DIMM rated at 1.35 V with ECC and registered signal processing, so the motherboard must provide DDR3 slots that accept registered ECC memory at that voltage.

Can I run these 1066 MHz CL9 modules in a system that currently uses slower DDR3 memory?

The kit operates at DDR3-1066 with CL9 timing; the memory controller will set a common speed for all installed DIMMs, so older slower modules will limit the kit to the lowest shared frequency.

How can I confirm the full 64 GB is recognised and ECC is active after installation?

Check the BIOS or UEFI memory information screen for 64 GB total capacity and ECC status enabled, then verify in the operating system with tools such as dmidecode or CPU-Z that show ECC correction active.
