Pros & Cons
Pros
- ✓ JEDEC-standard 1.2V DDR4-2133 runs at rated speed with no XMP or BIOS tuning
- ✓ Backed by A-Tech's lifetime warranty plus pre- and post-sale tech support
- ✓ Standard 288-pin unbuffered DIMM fits common DDR4 desktop motherboards

Manufacturer description
The A-Tech 8GB DDR4 2133 MHz UDIMM is a single desktop RAM module for adding capacity to a DDR4 PC or replacing a failed stick. It is a standard 288-pin, non-ECC unbuffered DIMM rated PC4-17000 (PC4-2133P) with CL15 timings. It runs at the JEDEC DDR4 standard 1.2V, so it works at its rated speed in compatible desktops without any XMP or BIOS tuning. This module suits older office machines, prebuilt towers and budget builds whose motherboards or CPUs officially support DDR4-2133. If you install it next to faster DDR4, your system will generally run every stick at the slowest shared speed…

Frequently Asked Questions
Will the A-Tech 8GB DDR4 2133 RAM work in my laptop?
No. This is a full-size 288-pin desktop DIMM. Laptops use smaller SO-DIMM modules, so you need an SO-DIMM version for a notebook.
Is this RAM ECC or registered?
Neither. It is non-ECC unbuffered (UDIMM) memory, the type used by consumer desktops. Servers and workstations that require ECC or registered DIMMs will not accept it.
Can I mix this module with faster DDR4 RAM I already have?
Usually yes, if your motherboard supports mixed modules, but the system will typically run all sticks at the slowest shared speed, here 2133 MHz with CL15 timings. For the best stability, pair it with matching DDR4-2133 memory.
What warranty does A-Tech offer on this memory?
A-Tech backs the module with a lifetime warranty, and its tech support team helps before and after purchase. Check the product listing for the full warranty terms.
Is it single-rank or dual-rank?
A-Tech lists it as 1Rx8 or 2Rx8, so you may get either a single-rank or dual-rank stick. Both run at the JEDEC standard 1.2V and PC4-17000 (2133 MHz) speed.
