  • 5 V standard voltage ensures broad platform compatibility

Server DDR3 ECC UDIMM kit

This A-Tech kit supplies 8 GB of DDR3 1866 memory in two 4 GB unbuffered ECC UDIMMs. Each module runs at 1.5 V with CL13 latency and uses a single-rank 1Rx8 organisation on a 240-pin DIMM. The kit is built for dual-channel servers and workstations that require error-correcting memory.

For DDR3 ECC unbuffered platforms only

It suits administrators upgrading or repairing servers and workstations that specifically accept DDR3 ECC UDIMM modules. Buyers whose systems need registered DIMMs, non-ECC memory, or a different DDR generation cannot use this kit. Always confirm the motherboard’s qualified-vendor list before ordering.

DDR3 1866 ECC unbuffered specification

The decisive figure is the DDR3 1866 ECC UDIMM rating at 1.5 V with CL13 timing. If the platform demands DDR3 ECC unbuffered DIMMs at this speed and voltage, the kit will fit; if it requires registered ECC, a different voltage, or another memory generation, it will not.

Questions about this item

Does this kit need a motherboard that takes DDR3 ECC unbuffered 240-pin DIMMs?

Yes, it is built for servers and workstations that accept DDR3 ECC UDIMM modules in 240-pin slots and will not fit desktop or laptop boards.

Will these 1.50 V modules run alongside older 1.5 V DDR3 DIMMs I already have?

They operate at the same 1.50 V standard voltage, so they can share a channel with other 1.5 V DDR3 sticks if the platform supports mixed ranks.

How can I confirm the kit is running at 1866 MHz with CL13 after installation?

Check the memory speed and latency in the BIOS or a system-info tool such as CPU-Z; they should show 1866 MHz and CL13 timings.
