The 8GB Dual Channel Memory Kits
Corsair Dominator Platinum with Corsair Link Connector (1.65V, 8GB Dual-Channel DDR3-2133 Memory Kit)
This memory kit from Corsair sport the lowest timings of 9-11-10-27, when compared with the rest of the contending kits. Its heat spreaders look menacing and they feature LED lighting when in operation.
The pair of memory modules don't work in isolation as they support the Corsair Link Connector feature. This allows you to connect all supported Corsair products (from CPU coolers to chassis) to each other for monitoring purposes. This in turn allows you to get a constantly updated situation picture of the operations of these interlinked components through a singular software control panel.
Crucial Ballistix Elite Series (1.65V, 8GB Dual-Channel DDR3-2133 Memory Kit)
This pair of memory modules from Crucial Ballistix Elite Series feature a distinctive black PCB and heat spreader of the same color that extends from it. This design makes this kit of one the more aesthetically pleasing memory modules that we've seen. Its voltage is rated at 1.65V and it has one of the lowest latency timings of 9-11-10-27, which will definitely help in its performance.
G.Skill RipjawsX (1.65V, 8GB Dual-Channel DDR3-2133 Memory Kit)
G.Skill memory modules tend to favor red heat spreaders; however, this particular kit has eschewed the usual and went with blue instead. The G.Skill RipjawsX kit is rated to operate at 1.65V with latency timings of 9-11-10-28. According to its official specifications, this kit is targeted at system builders who want to enjoy the computing prowess of the current third generation of Intel Core processors.
Kingston HyperX Predator (1.60V, 8GB Dual-Channel DDR3-2133 Memory Kit)
This pair of memory modules is one of the newest series from Kingston and one of the main changes to this series is the redesigned heat spreader and its stout design will be much appreciated by rig builders who need the extra headroom in order to accommodate their custom CPU coolers. It supports two Intel XMP profiles for easy configuration; the first profile lets the modules operate at DDR3-1600 while the other runs them at DDR3-2133.
Patriot Memory Viper 3 Intel Extreme Masters, Limited Edition (1.5V, 8GB Dual-Channel DDR3-2133 Memory Kit)
This pair of memory modules sport blue heat spreaders that feature the Viper 3 variation design for its heat dissipating capabilities to ensure performance stability; however, due to its stated latency timings of 11-11-11-27, it is actually one of the slowest in comparison to its other counterparts. It does support speedier timings at a lower base frequency at DDR3-1600, which makes it an ideal companion for current Intel platforms if you don't intend to overclock your system.
