Manufacturer description

The Crucial 16GB DDR4 RAM Kit (CT2K8G4DFRA32A) gives your desktop two 8GB modules rated at 3200MHz (PC4-25600) with CL22 timings. It is a simple upgrade for a system that is short on memory, or one still running a single stick. The kit runs at a standard 1.2V and uses the 288-pin UDIMM form factor found in DDR4 desktop motherboards. If your board or CPU tops out below 3200MHz, the modules downclock to 2933MHz or 2666MHz. That makes the kit a good fit for older Intel builds and first-generation AMD Ryzen systems as well as newer DDR4 platforms. Installing the matched pair in a dual-channel…

Frequently Asked Questions

Will this Crucial 16GB kit work in my laptop?

No. CT2K8G4DFRA32A uses 288-pin UDIMM desktop modules. Laptops need 260-pin SODIMM memory, so check the Crucial Upgrade Selector for a laptop-compatible kit.

My motherboard only supports 2666MHz. Can I still use this RAM?

Yes. The modules are rated for 3200MHz and downclock to 2933MHz or 2666MHz, so they run at the highest speed your board and CPU support.

Does this kit work in an AMD Ryzen or a newer DDR5 system?

It works in AMD Ryzen and Intel desktops that use DDR4 memory. It does not fit DDR5 motherboards, because DDR4 and DDR5 modules are physically keyed differently.

Is this ECC memory, and what voltage does it run at?

It is non-ECC unbuffered memory (UDIMM) running at a standard 1.2V, the normal spec for consumer DDR4 desktops.

What warranty comes with the Crucial CT2K8G4DFRA32A?

The product context does not state the warranty terms. Check the product listing or Crucial's website for current coverage before you buy.
