In addition to all the Haswell-E talk, memory chip makers are coming out to showcase their DDR4 (pdf) solutions as well. One such company is Corsair, which is now shipping Dominator Platinum DDR4 memory kits in 3300 MHz, 3200 MHz and 3000 MHz speeds. These kits are designed to be ideal for Asus’s new X99 motherboards revealed on Friday, as the RAM was developed in close collaboration with the motherboard maker.
“The new Dominator DDR4 memory kits, when paired with the ASUS X99 Deluxe and Rampage V Extreme motherboards, creates some of the fastest, most stable enthusiast PC platforms available for the new Intel Core i7 processors,” the press release said.
According to Corsair, hand-screened ICs were used to build these memory kits. They feature user-swappable colored light pipes, and a cooler operation thanks to patented DHX technology. Their temperatures can be monitored in real-time thanks to Corsair Link compatibility.
Corsair revealed the Dominator Platinum series along with the Vengeance LPX kits on August 15, as we earlier reported.
Meanwhile, HyperX, a division of Kingston, plans to demonstrate its HyperX Predator DDR4 memory kits this weekend during PAX Prime. The actual products will ship sometime in September, and they consist of five 16 GB kits (four DIMMs) starting at 1.2V and clocked at 2133 MHz, 2400 MHz, 2666 MHz, 2800 MHz and 3000 MHz. Like Corsair’s offering, these chips are designed for Intel’s X99 chipset and the Haswell-E processors.
G.SKILL also made an announcement on Friday, reporting that it achieved a DDR4 memory record at 4004 MHz. The company used LN2 extreme cooling, the Asus ROG X99 Rampage V Extreme motherboard and an Intel Core i7-5930K CPU. The score was validated by CPU-Z, the company’s press release said.
The news arrives after G.SKILL recently revealed its Ripjaws 4 Series of DDR4 memory kits. These memory chips include redesigned heat-spreaders in three different colors, extremely low voltages, quad-channel support, and high performance frequencies. These frequencies include 2133 MHz, 2400 MHz, 2666 MHz, 2800 MHz, 3000 MHz and 3200 MHz.
As we reported earlier this month, ADATA began shipping its DDR4 modules. The company also launched its overclocking memory, the XPG Z1, around the same time.

Make the IMC easy to OC as well, please :P
It is not really comparable, because the IPC changed. Latencies are starting at 15, but real world performance varies depending on workload, as per usual.
But 4 gigahertz RAM is still an achievement. It is just that modern CPUs, especially the kind you will see DDR4 used for at first (huge l3 cache 2011s) wiill benefit from ultra-high bandwidth the most because they have the largest FSB data rates, albeit without onboard graphics which is the best utilizer of high bandwidth ram. And even then, it is unlikely we will see a noticeable performance impact.
amd is supposed to be making their net chipset work with both ddr 3 and ddr4.
i believe the biggest advantage of ddr4 is that the overall throughput is higher from 1800mits to 2300 or something
The bigger question is what timing benchmark reductions will have to be achieved to drive demand for the product?
One thing you do have to keep in mind is that latencies tend to be higher for DDR4 than DDR3. Especially comparing at similar clocks. That should also improve over time.
As for AMD, they said they're still committed to high end computing, but I'll believe when I see it. I'm not holding my breath for them, until they show something that's worthwhile.
