Pros & Cons

Pros

  • ✓ Single-rank 1Rx8/1Rx16 design fits legacy boards that reject dual-rank sticks
  • ✓ Works at both 1.5V DDR3 and 1.35V DDR3L per JEDEC standard
  • ✓ Limited lifetime warranty plus pre- and post-purchase tech support
  • ✓ 240-pin non-ECC UDIMM format matches standard consumer desktop slots

Cons

  • ✗ 2GB per module is small; most builds need two or four sticks to be usable
  • ✗ CL11 latency is loose compared to CL9 DDR3-1600 kits
  • ✗ Sold as a single module, so matched dual-channel pairs cost double
  • ✗ No ECC support, ruling it out for workstation and server boards

Manufacturer description

The A-Tech 2GB DDR3 1600MHz module is a single 240-pin DIMM aimed at older desktops that still have an empty memory slot or a failed stick to replace. It runs at PC3-12800 speeds with CL11 timings, and it is a non-ECC unbuffered UDIMM in a single-rank 1Rx8 or 1Rx16 configuration, so it drops into standard consumer boards rather than server platforms. A-Tech builds it to JEDEC standard voltage, which means it works on 1.5V DDR3 boards and 1.35V DDR3L boards without manual tuning. If you are reviving a Core 2-era or early Core i-series machine, this is the kind of part that gets the system…

Frequently Asked Questions

Will this 2GB stick work in my desktop?

It fits any desktop board with a 240-pin DDR3 DIMM slot that accepts non-ECC unbuffered memory at up to 1600MHz. A-Tech recommends checking your system's manual for seating and channel guidelines before ordering.

Is this DDR3 or DDR3L?

Both. The module follows JEDEC standard and runs at either DDR3 1.5V or DDR3L 1.35V, so it works in boards wired for either voltage.

Can I use this in a server or workstation that needs ECC?

No. This is a non-ECC unbuffered UDIMM, not a registered or ECC module, so it will not work in platforms that require ECC memory.

Do I need to buy two for dual-channel?

Yes. This listing is a single 2GB module. Dual-channel operation requires two sticks in the correct slots, and your motherboard manual specifies which pairs to use.

What warranty comes with it?

A-Tech backs the module with a limited lifetime warranty and provides tech support before and after purchase. Every module is tested under the company's quality control process before shipping.
