G.Skill Has 32GB of DDR4 Memory Stable At 3333MHz With 1.35v

G.SKill recently announced that they had the fastest DDR4 memory kit in the world and was showing off that kit in the demo area at IDF 2014 today in San Francisco. Just this week we posted up a review on the G.Skill Ripjaws 4 16GB (4x4GB) 3000MHz DDR4 kit of memory, but it pales in comparison to the to the 32GB (4x8GB) 3333MHz memory kit that G.Skill is showing off here at the show.

G.Skill is pushing the boundaries of what is possible with DDR4 memory on the new Intel X99 platform by running this 32GB kit at 3333MHz with fairly aggressive 16-16-16-36 2T timings at just 1.35V. G.Skill is using SKhynix memory IC’s on this kit just like their other Ripjaws 4 kits. The only difference between the various models is that these are the tightest screened and are the only kits that are able to get these clock speeds. G.Skill admits that building kits for the retail market is very tough to do and that there are only currently a handful of these memory kits produced. That might not be a bad thing as the estimated price for this kit of memory when it comes out in early October will be $699 per 16GB kit (4x4GB). The kit will be available in black only and the part number is F4-333C16Q-16GRK.

Not just any motherboard has the ability to support DDR4 3333MHz memory though and G.Skill has only been able to get it to work properly on the ASUS X99 series boards. We know that the ASUS X99 series boards feature the special LGA2011-v3 OC Socket with additional pins for enhanced overclocking and it looks like ASUS might be onto something there as the memory vendors are seeing a difference between how the board manufactures are implementing the X99 chipset. G.Skill said they are having the best luck with overclocking DDR4 memory on the ASUS Rampage V Extreme X99 motherboard and that is the board they were using in their booth.

G.Skill was only showing off one benchmark in their booth and that was AIDA64 cache & memory benchmark. They were able to get 71GB/s read and 55GB/s write on this benchmark. The copy test was off the chart at an impressive 80.6GB/s! Note that G.Skill was using a 166MHz CPU strap with a 21x multiplier to reach these blazing fast speeds!
