32GB DDR3 ECC RDIMM kit

This kit provides 32GB of DDR3 1333 ECC registered memory in four 8GB modules. It is designed for Lenovo ThinkServer RD230, RD240 and TD200x systems that require registered DIMMs with error correction.

Works only in servers that take registered ECC DDR3

Buyers building or upgrading a standard desktop PC cannot use these modules because the platform expects unbuffered memory. Systems that need unregistered DIMMs or a different voltage should look elsewhere.

Verify your server accepts 240-pin DDR3 1333

Check the motherboard manual or service guide to confirm support for 1.5V CL9 2Rx4 modules and the maximum capacity per slot. Ensure all four slots can be populated with identical modules for the full 32GB.

Questions about this item

Will these 240-pin DDR3 1333 ECC registered DIMMs work in a standard desktop motherboard?

No. The modules are ECC registered DDR3 RDIMMs designed for workstation and server platforms such as the Lenovo ThinkServer RD230, RD240 and TD200x. They cannot be used in standard desktop computers or mixed with unbuffered memory.

Can I add this 4x8GB kit alongside existing unbuffered DDR3 modules in my ThinkServer RD240?

No. The kit uses registered ECC DDR3 RDIMMs (2Rx4, 1.5V, CL9). Registered memory cannot be mixed with unbuffered modules; all slots must be populated with registered ECC DIMMs of matching specification.

How do I verify the kit is running at PC3-10600 1333 MHz CL9 after installation?

Enter the system BIOS or use a hardware information utility; the memory should report DDR3 1333 MT/s, CAS latency 9, 1.5 V operation and ECC registered status for each of the four 8 GB modules.
