G.SKILL launches Extreme Low Latency DDR4-4000 CL15 32GB Memory Kits
G.SKILL is releasing an extreme low-latency, high-speed DDR4 memory kit at DDR4-4000 CL15-16-16-36 in a 32 GB (8 GB x4) capacity configuration under the classic Trident Z and the RGB-enabled Trident Z Royal memory series.
Once again, these extraordinary memory kits are manufactured using high-performance Samsung B-die ICs to achieve the world's lowest latency of CL15 at DDR4-4000. At G.SKILL, we are always searching for the ultimate memory kit, tuned not only for speed, but also for efficiency. This means pushing for lower latency timings. Previously, the best CAS latency that memory kits at the DDR4-4000 level could achieve was at CL17. This is surpassed by the new DDR4-4000 CL15-16-16-36 32 GB (8 GB x4) memory kit running under 1.5 V, shown validated on the MSI MEG Z390 ACE motherboard and Intel Core i7-9700K processor in the screenshot below.
Exceptional Bandwidth Performance on AMD X570
A lower CAS latency typically means a bump in bandwidth performance, and this is no different on the latest AMD Ryzen platform. Normally, AMD Ryzen 9 3900X processor bandwidth with popular DDR4-3200 CL14 kit would fall around 50 GB/s for memory read bandwidth in AIDA64. With the new ultra-efficient DDR4-4000 CL15 memory kit, the memory read bandwidth breaks 61 GB/s in AIDA64 with a few additional tweaks, along with over 58 GB/s in memory write and 65 GB/s in memory copy bandwidth speed, as demonstrated in the following screenshot with the MSI X570 Unify motherboard and the AMD Ryzen 9 3900X processor.
Availability & XMP 2.0 Support
This extreme low latency performance memory specification will support Intel XMP 2.0 for easy overclocking and will be available via G.SKILL worldwide distribution partners in Q4 2019.

50ns is not possible.
I'm getting ~61ns with 3900x and 3800c14 1:1 in Aida 64 memory benchmark.
Ryzen == latency

This is more like it.
Its been same old for so long, you can buy low CAS ram with low clocks and clock it high with high CAS, or just buy it like that for silly money.
Now there is high speed low CAS, wooo.
Prices will hopefully change all round now and clock this new ram even higher!
Anyone know what brought this around, a newer type of B die or better perhaps?

it could be a high bin of 8Gb b-die , mainly the very high voltage of 1.5v tells its probably nothing particularly new, seems they took some of their 4600-4800 cl 18 kits and clocked them down to 4000 cl 15, which makes sense, since there is very little point in running such high frequencies at the current time on intel and amd.

but 1.5v can´t cause problems on imc?
