Designed with a focus on Intel's latest 11th generation Rocket Lake processors and the new memory controller ratios, G.Skill has announced a wave of new memory kits designed to squeeze as much performance out of the platform. The new memory kits for Z590 and Rocket Lake feature speeds of up to DDR4-5333. They will be made available across multiple lines of its range, including the premium Trident Z Royal, Trident Z RGB, and the more affordable Ripjaw V series.

With memory performance and control getting some extra features with Intel's 11th gen desktop, the Z590 chipset with Rocket Lake processors now supports geared memory ratios between the memory controller and the DRAM data rates. The ability of Intel's memory controller in a 1:1 gear ratio can vary, certainly under ambient cooling methods, and not all of Intel's silicon can handle such high frequencies. This is where the gear ratio option becomes beneficial, taking some of the strain off the memory controller and allowing for high frequencies, with G.Skill capitalizing on this with its new memory kits up to DDR4-5333.

G.Skill's Trident Z Royal DDR4 Memory in Gold

The new G.Skill memory kits designed for Intel's Z590 (with Rocket Lake) start from DDR4-4266 with CL19 ratings, with two available capacities: dual-channel 32 GB (2x16) and 64 GB (2x32) kits. Also set to be available include DDR4-4400 kits with CL17 and CL18 latencies, including an operating voltage of 1.50 V in both the 32 GB and 16 GB kits.

Moving up, there's one kit of DDR4-4600 with CL20 with a total capacity of 64 GB (2 x 32 GB) and three different flavors of DDR4-4800; CL17 and CL18 with 2 x 8 GB kits, and CL20 with 2 x 16 GB. There's one 32 GB (2 x 16 GB) kit at DDR4-5066 with CL19 and an operating voltage of 1.6 V, with one kit maxing out at DDR4-5333 and CL21 latencies, with 2 x 8 GB memory sticks.

G.Skill has announced that its new Rocket Lake and Z590 kits have been validated on the ASUS ROG Strix Z590-E Gaming WIFI, the ASUS ROG Maximus XIII Apex, and MSI's MEG Z590I Unify motherboards with an Intel Core i9-11900K processor. G.Skill also stated that its DDR4-4800 CL17 16 GB (2 x 8 GB) kit uses Samsung B-die memory chips but didn't specify if this was the case across its range.

At the time of writing, G.Skill hasn't given us any pricing, but they are expected to launch in Q2 2021. With memory prices set to rise throughout the year, these kits aren't likely to be cheap. The G.Skill Trident Z Royal and Trident Z RGB will likely feature at the higher end of the pricing spectrum, with its Ripjaw Z series sitting as its entry point.

    Wth, those voltages? That's like DDR2 territory.
  • Marlin1975 - Monday, April 5, 2021 - link


    But yea 1.5v+ on DDR4. Thats a little wonky.
  • evilpaul666 - Monday, April 5, 2021 - link

    Yeah, is the warranty like "First POST guarantee!"?
  • nandnandnand - Monday, April 5, 2021 - link

    Get ready for beyond DDR2 territory. From an article on Wccftech:

    T-Force Gaming Confirms Development of Next-Gen DDR5 Memory Modules With Overclocking Support, Can Push Voltages Over 2.6V

    "T-Force also states that DDR5 memory has far greater room for voltage adjustment when it comes to overclocking support. This is primarily due to the upgraded power management ICs (PMIC) that allows for voltages over 2.6V. It is also detailed that existing DDR4 memory modules handled their voltage conversion through the motherboard but that changes with DDR5. The components that are required for the voltage conversion are now moved over to the memory DIMM itself, reducing voltage wear and noise generation while simultaneously offering increased room for overclocking."

    That's generally the realm of extreme overclocking where enthusiasts have chillers on their memory. Here, we are seeing XMP now pushing into 1.5V+ territory which has always been considered highly dangerous especially if memory is only cooled with air.
  • Hxx - Monday, April 5, 2021 - link

    its not gonna hurt the modules but they'll just crash and ofc your system along with it. At 1.5V they can easily hit 65C+ and somewhere between 65 and 70, b die crashes and im assuming these are dual rank b die. DR also runs hotter than SR which only compounds this issue. So these kits are for those willing to run active cooling or have exceptionally good air flow
  • bunnyfubbles - Wednesday, April 7, 2021 - link

    DDR2 voltage is 1.8-2.2, this is DDR3 territory.
  • LauRoman - Monday, April 5, 2021 - link

    What moterboard is that?
  • MenhirMike - Monday, April 5, 2021 - link

    Doesn't look like any released board. It's got an ASUS ROG logo, but none of those boards have those V-Shaped SATA Ports. So either a prototype/engineering sample, or an as of yet unannounced board (probably Z590?)
  • duynguyenle - Tuesday, April 6, 2021 - link

    It's either the Z490 Maximus XII Apex or Z590 Maximus XIII Apex, both of those have been announced (Z490 last year, Z590 since January). Z490 boards are generally available, but the Z590 version doesn't seem to be in stock at any UK retailers as of yet.
