Pros & Cons

Pros

  • ✓ 16GB total (2x8GB) doubles the common 8GB ceiling on older DDR3 desktop builds
  • ✓ Standard 1.5V DDR3, so no low-voltage memory controller required
  • ✓ Lifetime warranty from A-Tech on every order
  • ✓ US-based tech support available before, during, and after purchase

Cons

  • ✗ 1333MHz is the slow end of DDR3; 1600MHz kits exist for similar money
  • ✗ CL9 latency is loose compared to CL7/CL8 enthusiast DDR3
  • ✗ 2Rx8 dual-rank can limit slot population on some older chipsets
  • ✗ Non-ECC and unbuffered, so unusable in ECC servers or workstations

Manufacturer description

The A-Tech 16GB DDR3 kit is a straightforward capacity upgrade for older desktop platforms that still run on 240-pin DDR3 DIMMs. You get two 8GB modules rated at 1333MHz (PC3-10600) with CL9 timings, a 2Rx8 dual-rank layout, and standard 1.5V operation, so it drops into non-ECC unbuffered desktop boards without needing a low-voltage-capable memory controller. That configuration matters on Sandy Bridge, Ivy Bridge, AM3+ and similar era systems where the board caps out at four DIMM slots and 8GB per slot. Moving from 8GB to 16GB is the upgrade you feel on a retro or secondary build: more…

Frequently Asked Questions

Will this 16GB kit work in my desktop?

It fits desktop boards that take 240-pin DDR3 non-ECC unbuffered DIMMs at 1.5V. A-Tech advises verifying your system's supported memory specs before purchase, since maximum capacity and supported ranks vary by motherboard.

Is this one 16GB stick or two 8GB sticks?

It is a two-module kit: 2 x 8GB DDR3 DIMMs totaling 16GB, meant to be installed as a matched pair in two slots.

What speed and timings does this RAM run at?

DDR3 1333MHz, also listed as PC3-10600 or PC3-10600U, with CL9 timings, 2Rx8 dual-rank organization, and 1.5V standard DDR3 voltage.

Can I use this in a server that needs ECC memory?

No. These are non-ECC unbuffered UDIMMs, so they will not work in systems that require ECC or registered/buffered memory.

Does A-Tech warranty this memory?

A-Tech states it provides a lifetime warranty on all orders and offers complimentary US-based tech support before, during, and after purchase. Check the product listing for current warranty terms.
