G.SKILL Ares 16 GB DDR3 2133 Kit

The G.SKILL Ares Series F3-2133C11D-16GAR is a 16 GB dual-channel kit built from two 8 GB unbuffered DDR3 modules. Rated at 2133 MHz with timings of 11-13-13-31 and a CAS latency of 11, the kit runs at 1.50 V and includes Intel XMP profiles for second, third and fourth generation Core processors on LGA1155 and LGA1150 platforms. A low-profile red heat spreader stands 3.2 cm tall and carries green LEDs.

Who this suits and who should look elsewhere

Builders upgrading or repairing LGA1155 or LGA1150 systems that support DDR3 2133 will find the rated speed and XMP support straightforward to enable. The low-profile height clears large CPU coolers and fits small-form-factor cases. Systems requiring ECC, registered modules, or a different DDR generation should select a different kit.

Deciding specification — DDR3 2133 at 1.50 V

The single specification that decides fitment is the DDR3 2133 rating at 1.50 V. Only motherboards and CPUs that officially support DDR3 at this voltage and data rate can run the kit at its rated 17.0 GB/s per channel without manual timing adjustments.

Questions about this item

Will the 3.2 cm Ares heat spreader clear my oversized CPU cooler?

The low-profile spreader is only 3.2 cm tall, leaving ample clearance for most large air coolers and small-form-factor cases.

Can I mix these CL11 2133 MHz modules with slower DDR3 sticks I already own?

The motherboard will run all populated slots at the speed and timings of the slowest installed kit, so your existing modules will dictate the final frequency.

How do I confirm the kit is running at its rated 2133 MHz 11-13-13-31 timings?

Enable the Intel XMP profile in BIOS, then verify the active frequency and timings with CPU-Z or the motherboard’s built-in memory-info screen.
