G.Skill RipjawsZ F3-2133C9Q-32GZH

The G.Skill RipjawsZ represents further evolution of the RipjawsX series we’ve discussed above. Early RipjawsZ kits were marketed as quad-channel memory for LGA2011 platforms but eventually this name came to be applied to the specific shape of the heatsinks and the RipjawsZ was positioned as dual-channel memory for LGA1155 platforms as well. The F3-2133C9Q-32GZH illustrates that evolution. It was originally meant for X79-based mainboards but the compatibility list was expanded after the release of Ivy Bridge CPUs and now includes a lot of Z77-based mainboards.

The RipjawsZ F3-2133C9Q-32GZH kit is shipped in a plastic blister wrap, just like the other memory kits from G.Skill.

Now let’s take a look at their exterior design. The heatsinks are different from those of the RipjawsX modules. They are still made of aluminum but the color is changed into glossy black. Moreover, the heatsinks have become somewhat more solid, yet the RipjawsZ modules are still not very tall and are not likely to conflict with massive air coolers for CPUs. The full height of each module is 40 mm, exactly as that of the RipjawsX series.

We have no doubts about the cooling efficiency of the RipjawsZ heatsinks. The modules do not get as hot as their cousins whereas the heatsinks are shaped intricately to enlarge the total heat dissipation area.

The heatsinks are secured on the memory chips with a gluey thermal interface material. Below them we can find a BrainPower PCB typical of G.Skill products and specially selected 4-gigabit DDR3 SDRAM chips from Samsung. The components have a good overclocking reputation. The B83U854 1.00 PCB is optimized for clock rates above 2 GHz whereas the SEC HCH9 chips are perhaps the most popular choice for high-speed overclocker-friendly DDR3 SDRAM.

The G.Skill RipjawsZ F3-2133C9Q-32GZH kit seems to be good from every aspect, including its specifications. Its four 8GB modules can work in DDR3-2133 mode which is not covered by the official specs of CPU-integrated memory controllers. Here is the full picture:

  • 32 GB Dual-channel kit consists of four memory modules, 8 GB each;
  • Nominal frequency: 2133 MHz;
  • Timings: 9-11-11-31-2T;
  • Supports XMP;
  • Voltage: 1.6 V.

The RipjawsZ F3-2133C9Q-32GZH has a slightly increased default voltage but can work at CL9. This is reflected in the duplicated XMP profiles:

This DDR3-2133 SDRAM kit is a true overclocker-friendly product whose rated mode is beyond standard ones. It undergoes presale testing and comes with a lifetime warranty but G.Skill guarantees its stable operation with only a limited number of mainboards which mostly include flagship models from ASUS, Gigabyte and MSI based on Intel’s Z77 chipset.
