Much like the recent swathe of X99 motherboard previews we have seen, memory manufacturers are getting on board with showcasing their DDR4 memory modules to use with the Haswell-E platform. Unlike the CPUs from Intel, there is no formal NDA as such, allowing the media to report the design and specifications, although because real-world performance requires the CPU, no-one is able to post benchmark numbers.

The new DDR4 from G.Skill is the next DRAM module manufacturer to come out with an official press release, and following the previous high performance Ripjaws DDR3 range G.Skill will introduce its memory under the Ripjaws 4 moniker with a new heatspreader design.

G.Skill’s press release confirms the voltage ranges for DDR4, with 1.2 volts being standard on 2133 MHz to 2800 MHz kits, with the higher performance modules at 3000 MHz and above requiring 1.35V. The product line that G.Skill is aiming to release at launch is quite impressive with all the 1.2 volt modules in 16GB, 32GB and 64 GB kits. Due to the extra binning and higher tolerances of the more performance oriented kits, the DDR4-3000 C15 will be in 16GB or 32GB kits, DDR4-3000 C16 will be in a kit 32GB and the top line 3200 MHz C16 will be in a 16GB kit only.

G.Skill is reporting full XMP 2.0 support, and that this new module design matches the 40mm height of previous Ripjaws designs, allowing previous CPU coolers to be matched with this generation. As the modules are launched, the three colors G.Skill is pursuing are blue, red and black. I know G.Skill monitors our news, so if you really want another color in there, make a note in the comments.

Preorder pricing puts these modules at:

DDR4-2133 C15 4x4GB: $260
DDR4-2400 C15 4x4GB: $280 / £240
DDR4-2666 C15 4x4GB: $300 / £290
DDR4-3000 C15 4x4GB: $400 / £380

DDR4-2133 C15 4x8GB: $480
DDR4-2400 C15 4x8GB: $530 / £440
DDR4-2666 C15 4x8GB: $550 / £500

    They're definitely a crowd favorite at this point. Interesting to see that everyone's first wave of DDR4 has such high latency. Every kit I've seen so far will likely be 65-90 ns of latency. Not a huge deal because on X99 quad channel I expect these kits will be tearing out 60-90 GB/s.

    GSkill makes incredibly good memory. I prefer it over even Crucial. I've always had great luck with Mushkin, too, but their flair has been missing since the SD-RAM day's.

    Every PC in my house has GSkill RAM. When I upgraged from 4GB to 8 at work, it's GSkill. I've got another 8GB Sniper kit coming Monday.

    And black's enough for me - the blue and red have their place (and I've got both), but I don't always want to color-coordinate my PC. Give me black and I'm good.

    In the end, it doesn't really matter since I don't have a Window in my case. Useless heatsinks, graphics and marketing mean nothing to me. I will just base my purchase on reviews, specs and price.

    DDR3 1600 CL9 had an effective latency of 11.25ns. DDR4 3000 CL15 is at 10ns.

    While the DDR4 modules available in the first badge are obviously not the most high end we will eventually see, its not a step down from mainstream DDR3 at the very least.

    That isn't the effective latency. Run a benchmark right now and you'll see the effective latency. I've never heard of main memory having sub 40 ns latency. It just doesn't exist.

    I do see what you're referring to. Typical high end non-enthusiast kits that have been around for over a year have been 2133-CL9 for lowest latency which works out to 8.43 ns. The lowest latency kit on this page is your cited 3000-CL15 with 10ns. The slowest on this page is the 2133-CL15 with 15 ns of latency. The latency nearly doubles for a lower priced, equal capacity DDR3 kit that's been around for a while (something like the F3-17000CL9Q-16GBZH). You gain the lower voltage if that's a big deal to you (which it isn't in this market segment). It's the cost of new technology.

    Once upon a time we had DDR-3200 GB/s.
    Now we have DDR4-3200 MHz. How things have advanced.

    Once upon a time, we had 64k x 1 DRAM. How things have advanced.

    Once upon a time we had sound waves traveling down tubes of mercury. How things have advanced.
