G.Skill has announced a new series of high-end 16 and 32 GB DDR4 kits for Intel’s Coffee Lake processors. Following in the footsteps of other vendors who have announced similar highly clocked 32 GB kits, the new G.Skill DDR4-4000+ kits offer 2 and 4 matched DIMM sets with high frequencies and CL17 timings. The new Trident Z RGB modules require a high-quality Intel Z370-based motherboard that can deliver “clean” power to them as well as a processor that can handle both high frequencies and relatively low latencies.

G.Skill’s low-latency Trident Z RGB dual-channel kits for Coffee Lake CPUs are rated for DDR4-4000 CL17 17-17-37 at 1.35 V, DDR4-4133 CL17 17-17-37 at 1.4 V and DDR4-4266 CL17 18-18-38 at 1.45 V. The kits consist of 8 GB modules based on pre-binned Samsung’s B-die 8 Gb ICs made using the company’s 20 nm process for DRAMs, just like all the other high-end DDR4 modules today. The new DIMMs come with XMP 2.0 SPD profiles to simplify their installation on supporting platforms.

When we first encountered G.Skill’s Trident Z memory kits for Intel’s Coffee Lake/Z370 platform earlier this year, we noticed that the company relaxed their tRAS sub-timings when compared to DIMMs designed for Intel’s X299 platform. Much to our surprise, the new low-latency Trident Z RGB DDR4-4000+ 32 GB kits shrink all the timings rather considerably compared to the company's other high-speed DDR4 kits. In fact, the new Trident Z RGB modules offer the lowest latencies among all DDR4-4000+ kits announced to date. Apparently, at least some of Intel’s latest desktop CPUs can handle not only extreme data transfer rates well beyond DDR4 specs, but also can do so with CL17 timings, albeit with a 12.5% –20% overvoltage and G.Skill’s tinkering.

To validate its Trident Z RGB DDR4-4000+ CL17 kits, G.Skill uses Intel’s Core i7-8700K CPUs as well as ASUS’ ROG Maximus Hero motherboards. Like other highly clocked 4 DIMM kits announced this fall, this comes with the caveat that not all Coffee Lake processors can handle ultra-fast memory modules in a 2 DPC configuration. Therefore, to take advantage of G.Skill's DDR4-4266 CL17 kit one is going to need some luck. At the same time, the company claims that hitting 4000 – 4266 MT/s is not very difficult on modern platforms and processors that can handle such speeds are not too rare (but a good cooling system is a must  due to DRAM overvoltage).

 

In addition to its low-latency DDR4-4000+ CL17 kits for Intel’s Coffee Lake/Z370 platform, G.Skill has also introduced the absolutely fastest 32 GB DDR4 kit to date that is rated to run at 4400 MT/s with CL19 19-19-39 timings and 1.5 V. The kit naturally requires a high-end Z370 motherboard and a pre-binned CPU with a memory controller that can support such data transfer rates.

With the addition of all the latest kits that G.Skill introduced in the recent weeks, the company’s lineup of modules for Coffee Lake/Z370 platform now looks as follows:

G.Skill plans to start sales of its Trident Z RGB DDR4-4000+ CL17 kits for Intel’s latest platform in January 2018. The manufacturer never touches upon MSRP of its high-end modules in press releases, but expect the new products to be priced well above average dual-channel kits. In the meantime, the fastest Trident Z RGB 32 GB dual-channel kit that can be ordered now is rated for DDR4-4000 CL18 and costs $649.99 (at press time, it was out of stock at Newegg).

    Oh look, more overpriced, price fixed no less, RAM. Sigh... Reply

    I don't think g.Skill is at any fault. They're buying the DRAM chips from suppliers who are currently charging quite a bit right now. They're having to pass those costs to the consumer so they can make their business stay afloat.

    The moment g.Skill can buy DRAM chips for less is when you, the consumer, will see more favorable prices, too.

    Oh, to be clear, I don't blame GSkill, per say. This is a price-fixing scheme from DRAM manufacturers. It needs to end, and these companies need to be prosecuted for creating artificial supply shortages and price-fixing across company lines. It's absurd and it's illegal, no less. But, nowadays, companies basically get away with it by saying "No, we're not doing that! We promise!" and it just continues... It's really become absurd. Reply

    I just built a PC for my nephew for Christmas. I had to pay almost $200 for 16 GB of 2400 DDR4... The very same kit that cost $50 a year ago...
    This is so unbelievable...

    I don't think I ever saw 16GB of RAM for $50 new. Maybe used on Ebay. Reply

    Quickly looking at the cheapest 8 GB module in Germany reveals that it did indeed drop to 23,75€, which would result in ~50$ for 16 GB. However, that was just for a 3 weeks before the price rose again:

    I got a 16GB kit of Corsair Vengeance DDR3 1600Mhz for $80 AUD years back.
    Now their cheapest is $209 for DDR3, $269 for DDR4.

    To say it sucks is an understatement.
    To make matters worst... I had intentions of going LGA2066, so I need a quad-stick kit... Which means the lowest is $600 for a 32GB kit.

    @Beaver: if RAM is that expensive, did he really need 16 GB? RAM is about the simplest thing to upgrade later on. And with SSDs it's not as bad to fill the RAM as it used to be. Reply
