The kits are rated at DDR4-4000 with timings of CL15-16-16-36 and include four Trident Z modules (4 x 8GB) using Samsung B-die ICs. G.Skill points out that its previous latency "floor" was CL17. According to the company, it validated these new modules using an Intel Core i7-9700K octa-core processor and an MSI MEG Z390 ACE motherboard.
Switching over to the AMD side to things, G.Skill shows that the same modules were able to boost AIDA read bandwidth from 50GB/sec with its DDR4-3200 (CL14) modules to 61GB/sec with their DDR4-4000 counterparts. In addition, the company says that memory write and memory copy operations crack the 58GB/sec and 65GB/sec barriers respectively. G.Skill’s AMD testing was performed with a Ryzen 9 3900X processor and MSI X570 Unify motherboard.
It should be noted that these new DDR4-4000 modules are available in one of two styles: the classic Trident Z and the Trident Z Royal. While the former has a stealth black look that is quite unassuming, the latter is decked out with plenty of blingy gold with RGB lighting and crystal-like flourishes. It's definitely an interesting look for a gaming rig, but we’ve grown accustomed to Royal family at this point.
G.Skill has not yet provided pricing for the new 32GB DDR4-4000 Trident Z memory kits, but does affirm that they will be available worldwide later this quarter.
