  • 5 V standard voltage ensures broad DDR3 platform compatibility

32GB DDR3 ECC kit for servers

This 32GB kit contains eight 4GB DDR3 1600 ECC UDIMM modules built for server and workstation platforms that require error-correcting unbuffered memory. It is not compatible with standard desktop or laptop computers. Buyers who need memory for consumer motherboards cannot use this kit.

240-pin unbuffered dual-rank modules

Each module uses a 240-pin DIMM form factor with a 2Rx8 dual-rank layout and operates at the standard 1.5V DDR3 voltage. The unbuffered design connects directly to the memory controller without a register, so the system must support ECC UDIMM specifically. Builders whose boards require registered DIMMs cannot install these modules.

DDR3 1600 CL11 interface limits

The kit runs at DDR3 1600 (PC3-12800) with a CAS latency of 11, which defines the maximum throughput and timing envelope of this interface. Systems limited to lower DDR3 speeds will downclock the modules automatically. Workloads that demand higher bandwidth or newer DDR generations must use a different platform.

Questions about this item

What bandwidth does the PC3-12800E DDR3 interface cap at in practice?

The PC3-12800E DDR3 standard caps theoretical bandwidth at 12,800 MB/s per module; real-world throughput is lower due to protocol overhead and system timing.

What physical slot and clearance does this 240-pin DDR3 UDIMM kit require?

Each module uses a standard 240-pin DDR3 DIMM slot; ensure the server or workstation chassis has enough vertical clearance for eight full-height sticks.

How do I install the eight 4 GB modules and what is the common mistake?

Power off, open the chassis, align each module's notch with the slot key, press firmly until the retention clips click; the common mistake is not seating all eight modules fully or ignoring the motherboard's channel population order.
