We said over and over that Haswell-E was just around the corner, and after all that waiting and anticipation, today marks the official launch of the new CPU line from Intel (see our review of Haswell-E). It's not just about the processors, though -- it takes a village of components to raise Haswell-E the right way, and if you're looking to set records, G.Skill makes a strong case for its Ripjaws 4 Series. At present, G.Skill and its Ripjaws 4 Series of DDR4 RAM own the DDR4 frequency record after hitting 4,004MHz.
There are always caveats to this level of extreme overclocking, such as cooling. As you probably guessed, it took doses of LN2 to keep things cool enough to set the record. That's a buzz kill if you're only interested in stable clocks using air or liquid cooling, though it's par for course in the overclocking sector.
G.Skill also had to drop down to single-channel mode. In doing so, the company was able to push its Ripjaws 4 to 2,002.2MHz (4,004MHz effective) with 17-25-29-50 timings. The memory was plopped into an Asus ROG Rampage V Extreme motherboard with an Intel Core i7 5930K processor.
It's only a matter of time before the record is broken -- perhaps by G.Skill -- but for now, this is where the bar has been set.
