Featuring the AMD EXPO overclocking profile, these specifications are optimized for compatible AMD Ryzen DDR5 desktop platforms and will join the G.SKILL Trident Z5 Neo RGB and Flare X5 series.



In addition to the 256 GB high-capacity kit specification, G.SKILL also offers a high-speed DDR5-6400 CL36-44-44-102 128 GB (64 GB x2) memory kit. Aiming to deliver an excellent balance of speed and capacity, and validated for compatibility on Intel DDR5 platforms, this specification is ideal for users seeking high performance for a wide range of professional applications, AI workloads, and content creation tasks.

Specifications List
For a list of kit specifications based on the high-density 64 GB capacity module, please refer to the table below. It is very important to note that these kits based on 64 GB modules, built with new high-density IC chips, will require a motherboard BIOS update, dated 2025 or newer with 64 GB module support

Availability
These new high-performance 256 GB (64 GB x4) and 128 GB (64 GB x2) DDR5 memory kits are currently shipping to G.SKILL's worldwide distribution partners. Select models are already listed at retail, with a broader range of configurations expected to follow.

Nice kits; I wonder how much they will be asking for them?
It really is too bad, though, that they do not offer any ECC, which I would consider a requirement for any 4x DIMM kits, especially at these capacities.
Seeing as AM5 support Unregistered ECC (both platform, and most consumer CPUs), I really wish it would become the standard for DDR5+

Hopefully @ir_cow you have review sample on the way. Really curious whether AM5 CPUs really can handle this kit without any stability issues popping up.

V-Color DDR5 6400 kit has asking price of $460 on newegg, Corsair and Kingston kits for Intel(CUDIMMs) are bit more expensive. So given this is twice the capacity expect twice the price.

Edit: Finally these high capacity memory kits arent a vaporware.

None is being sent to me that I know of yet. As far as compatibility goes, 2x 2R hasn't changed much. 6000 1:1 (yes), 6400 1:1 (maybe). 2:1 IMC ratio yes.

4x 2R you are lucky if 5200 MT/s works in a 1:1. Haven't tried 2:1 yet myself. In short you will be trading memory latency for memory capacity.

2025 finally became the year of 256gb on consumer desktops.
I'm glad by with 4x64gb setup, that's the sole reason that made me jump from am4 to am5

Even I would love to jump to AM5 just to get 128GB of RAM(64GBx2) compared to running all 4 slots maxed out on AM4 setup. I am worried about stability since current AM5 cpus dont fully enable features of DDR5(Intel Core 200 series has support for sub channels, partial ECC feature on DDR5 and additionally clocked DIMMs) so wont mind waiting for Zen 6 CPUs.

My previous (still in use as a headless "server") AM4 setup had 4x32GB at 3200MHz. Never had any issues with it, rock solid and had multiple months of uptime, only restarting for kernel updates. And it was as easy as just enabling XMP, didn't need to mess with anything.

I am worried about stability since current AM5

I had some headaches tuning my 4x64GB kit, but it was due to a couple of factors, such as my sticks being 4x individual CUDIMM 6400MHz DIMMs, with no other profile stored, and me not having enough free time to mess with the configs that often. I managed to get 4800MHz running stable somewhat quick, and then spent lots of time changing BIOSes and tuning configs until I managed to get 5200MHz stable, which is what I'm using ATM.
As a side note, I totally would not recommend spending the amount of time I did to manage 4800->5200, unless you enjoy tinkering with such OC things. The extra bandwidth that I got was totally not worth the time, but I kinda enjoyed the process.

dont fully enable features of DDR5(Intel Core 200 series has support for sub channels, partial ECC feature on DDR5 and additionally clocked DIMMs) so wont mind waiting for Zen 6 CPUs.

Sub-channels are supported, what do you mean? The current Zen4/5 IOD has 2x64-bit controllers, each controller is capable of addressing the 2x32-bit channels on a stick without issues. If you are comparing that to Intel's current 4x32-bit controllers, that honestly has no difference whatsoever in practice.
Regarding ECC, the on-die ECC feature works fine and is transparent to the actual CPU, so there's no difference on how it behaves on an intel vs AMD CPU. It's kinda nice but not really that relevant integrity-wise. Side-band ECC afaik depends a lot on which mobo you're using, both Asus and Asrock support UDIMM ECC on AM5, not sure about others. Arrow lake on the other hand only supports it on W880 chipset, and not on consumer platforms, which is honestly worse than AMD's case IMO.

Do agree on the CUDIMM support. If the high-end Zen 6 CPU comes with CUDIMM support and more cores, I may get one to replace my 9950x.

128GB DDR5 6000 kits are already listed on Newegg for around $400(for non RGB Flare) and $420 for RGB version.
