Introduction

I would like to thank ASUS for providing the CPU, motherboard, and graphics card used in this review. This review would not have been possible without their support. Also, many thanks to G.SKill for providing the memory.

I recently covered a single-sided 2933 MHz kit from none other than G.Skill, a company whose memory sticks you will find in my motherboard testing rigs time and again. Although 2933 MHz is the maximum currently available memory speed on the platform natively, such speeds are expensive, and not everyone can afford that sort of investment on memory alone. I mentioned this to my G.Skill rep and told him that I would not mind looking at some other single-sided kits using slightly less voltage; I also mentioned that running four instead of two sticks seems to increase performance on Haswell. My rep quickly responded with a 16 GB kit for me to try, fresh on store shelves in just the past few weeks. The G.Skill RipjawsX F2-2133C9Q-16GXL is a quad-stick kit built for the Haswell platform specifically, featuring multiple voltages modes via multiple XMP profiles built right into the stick itself. Are four sticks better than two? Let's take a look!
