When it comes to overclocking, getting memory speeds high can be quite the challenge when you also need larger capacities. The more memory you have and the more slots it takes up, the more unstable it becomes. G.SKILL has a solution to this with its massive 384GB kit of 12 modules, running at DDR4-4000, a fair bit over the standard DDR4-2666 that most systems default to.
This huge memory kit uses high density 16Gb ICs, and was put to use with an Intel Xeon W-3175X and ASUS ROG Dominus Extreme motherboard. This is the overclocked 28 core Xeon released earlier this year. With such speeds and densities made available, it should help the CPU go much further.
If such huge densities are not required, and you just want the highest clocks possible, G.SKILL also showed off at Computex this year, a DDR4-5200 kit of 2x8GB modules. This is currently the fastest dual channel configuration on the market, going under its Trident Z Royal branding, and features some very low timings for the frequency of CL18-22-22-42. It was paired up with an Intel Core i7-9700KF with an MSI MPG Z390I Gaming Edge AC motherboard.
A sweet-spot kit was also shown with a still very high frequency kit of DDR4-5000, but the timings were pushed to be extremely aggressive at CL17-17-17-37, which is quite a significant jump over the 5200 kit. There were two high-density kits on show too, a DDR4-4300 64GB kit using 8 modules, and a tight timing DDR4-4000 4 module kit with CL16-18-18-38.
Some preliminary kits for AMD’s new Zen 2 series X570 motherboards were on display, although they were not tuned to quite the same degree as the Intel kits, something that AMD has battled since the original Ryzen launch. ASUS has some interesting features on its motherboards that should help with this in the future, but even on a fresh launch, kits were seen working at DDR-4000 CL18, and 32GB kits of DDR4-3600 with CL14.
No prices or availability were listed, but ‘high’ and ‘June’ would be the most likely answers. Still, DDR4 development isn’t dead yet, and we’re not likely to see DDR5 any time soon, so higher speed memory is always welcome, even if there is a point of diminishing returns.
