Frequently Asked Questions

Will this Kingston 4GB DDR3 stick work in my laptop?

No. The KVR1333D3N9/4G is a full-size 240-pin desktop DIMM. Laptops use smaller SO-DIMM modules, so you need a SO-DIMM part for a notebook.

What are the exact specs of the KVR1333D3N9/4G?

It is one 4GB DDR3 module running at 1333MHz with CL9 latency at 1.5V. It is a 240-pin unbuffered, non-ECC DIMM organized as 512M x 64, with FBGA chips and gold contacts.

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

Only if the board also accepts non-ECC unbuffered DIMMs. This module is non-ECC and unbuffered, so systems that require ECC or registered memory will not run it. Check your board's memory support list first.

Can I mix this with the DDR3 sticks already in my PC?

DDR3 modules at the same 1.5V voltage generally work together, and mixed speeds usually run at the slowest module's speed. Matching the exact KVR1333D3N9/4G part number gives the most predictable result, especially in dual-channel setups.

What warranty comes with Kingston ValueRAM?

Kingston backs this module with a lifetime warranty and free technical support. Check Kingston's warranty page for the current terms and how to file a claim.
