"This 16 GB quad-channel set of RipjawsZ is one of the higher speed bins in their X79 quad-channel line-up, with a rated speed of 2133 MHz. This set of memory delivered great performance throughout testing and was one of the better performing sets, especially when overclocked. Running at an overclocked 2414 MHz, this kit ran at the highest overall speed of all the modules. Not the largest increase over the baseline, but the highest speed overall. By loosening up the latencies and giving the modules a small boost in voltage, the modules responded well with increased bandwidth and memory performance. I think with even looser latencies and a better memory controller, there will still be some speed left in the modules – looks like it’s time for a 3930K!
When I first laid eyes on these modules, the first thing I noticed was the new look of the RipjawsZ heat shield alongside the black PCB. The new design is taller, so it sits further out into the airstream to and from the CPU cooling solution. Although this allows the modules to be kept cool under load, you will still run into same interference issues when all of the DIMM slots are populated on the motherboard. There is not as much open space along the top of the heat shield as on the earlier design, but the modules do not seem to heat up above ambient air temps with a small amount of airflow over them.
Backed by a lifetime warranty, G.Skill has these RipjawsZ modules prices aggressively at $159 for a 2133 MHz kit. Even with the low price of DRAM, this presents an enormous value for the end user looking to get increased memory performance."
