A-Tech 4GB DDR3 1333MHz ECC UDIMM

This 4GB DDR3 1333MHz ECC unbuffered UDIMM is built for servers and workstations that require error-correcting memory. It operates at 1.5V with CL9 latency and uses a 240-pin form factor. The module carries Supermicro certification and uses Hynix chips for validated compatibility.

Suits ECC DDR3 systems only

This module fits systems that accept DDR3 ECC unbuffered UDIMMs at 1333MHz. It will not work in platforms that require registered or fully buffered DIMMs. It is also unsuitable for any board limited to non-ECC memory or a different DDR generation.

Single rank constraint

The module is organised as 2Rx8 dual rank, which counts as two logical ranks per DIMM slot. Systems with a strict single-rank-per-channel limit cannot use this part. Buyers must verify that their motherboard or server supports dual-rank unbuffered ECC UDIMMs before ordering.

Questions about this item

Does DDR3 1333MHz PC3-10600 set the maximum data rate for this module?

Yes, the module runs at DDR3 1333MHz, which is the PC3-10600 standard, so that speed is the ceiling for each stick.

Will this 240-pin ECC UDIMM fit a standard server DIMM slot?

The stick uses the 240-pin ECC UDIMM form factor, matching the keying and length of regular DDR3 server slots.

How is the module installed, and what step is often missed?

Align the notch with the slot key, press straight down until both side clips click, then confirm the system recognises the full 4GB in BIOS.
