G.SKILL Reveals World's First Large Capacity 256 GB (64 GB x4) DDR5 U-DIMM Memory at DDR5-6000 CL32 Overclocked Speed
G.SKILL International Enterprise Co., Ltd., the world's leading brand of performance overclock memory and PC components, is thrilled to unveil DDR5 memory with an ultra-high kit capacity of 256 GB (64 GB x4), overclocked to DDR5-6000 CL32. Built with high-performance SK hynix DDR5 ICs, this overclock memory speed and timing pushes the boundaries of memory overclocking by fully loading 4 modules of high-capacity DDR5 64 GB U-DIMM modules on a single system; marking a new milestone for high-performance computing, content creation, AI applications, and advanced workstation workloads.
Overclocked, Ultra-Capacity 256 GB (64 GB x4) at DDR5-6000 CL32 In content creation and recent advancements in AI, the need for higher DRAM capacity is essential. Whether calculating large language models or working with complex or high-resolution video content, high-speed memory of high-density 64 GB modules would help to provide a smoother and more efficient workflow. Loaded with AMD EXPO memory overclock profiles, see the DDR5-6000 CL32 256 GB (64 GB x4) kit being stress-tested in the screenshots below on the ASUS ROG CROSSHAIR X870E HERO motherboard with the AMD Ryzen 7 9800X3D desktop processor, as well as on the MSI MPG X870E CARBON WIFI motherboard with the AMD Ryzen 9 9900X desktop processor.Showcasing Extreme Overclock at up to DDR5-7000 CL38-50-50 with 256 GB (64 GB x4)
Through extensive research and development, G.SKILL memory also demonstrates the overclock potential and limits of ultra-high capacity 64 GB memory modules. Combining 4 of these high-density 64 GB modules for a total of 256 GB, the following screenshot shows this massive capacity kit operating at DDR5-7000 CL38-50-50 on the MSI MEG X870E GODLIKE motherboard and AMD Ryzen 7 9800X3D desktop processor.
Additionally, the massive kit capacity of 256 GB is showcased in low latency DDR5-6400 CL32 in the screenshots below, on the ASUS ROG CROSSHAIR X870E HERO motherboard with the AMD Ryzen 9 9900X3D desktop processor and the MSI MAG B850M MORTAR WIFI motherboard with the AMD Ryzen 7 9800X3D desktop processor

256GB is good to have primer pro with 4k+ projects together with after effects simultaneously.
128GB can also do it (from personal experience), but it on the edge.
OR, as I always say: "Ram, bam, thank ya Ma'am" hehehe :D
Looking on ebay what's really frustrating is vendor locked TR CPU's are often much cheaper but once you try to get a refurbished DELL then the expense goes right back up on "recertified/renewed" brand name alone. At one point I was just looking at getting some shucked DELL TR board for $125 + PSU + Dell locked CPU for under $800 but then I came to my senses when I realized I'll have to build a case for that kind of Frankenstein motherboard as well as finding a proper wiring harness just for the power switch - ugh no thanks, not that desperate yet.
Just curious :D
I use 128GBs on my current workstation and it helps a bit with my work, but probably less than it would with an AI workload by far. I generally don't use more than 90GBs even with VMs, in truth.
Managed to workaround it for now by really lowering my batch sizes, but now my GPUs are becoming really data starved and training runs are taking 10~20 hours :(
I should really finish testing up my new 256GB rig and move things over to make my life easier.
I lowered the requirements (as in lower batch sizes) for the time being as a short-term (and slower) solution, but the proper one would be more memory within the new setup.
I saw they are using 4 dimm modules. I barely use my 2x32Gib DRAM. The timings for that product in this news piece could be much better compared with my beginner overclocking daily stable result.
I'd even be ok with more lane sharing like the following but nevermind board makers doing anything sensible....
x4 (NVMe for CPU)
Slot 1 = x16 (or x8[x4x4] or or x4x4[x8] or x4x4x4x4)
Slot 2 = x4 (or 8 SATA)
Slot 3 = x16 (bifurcation with 1st slot)
Slot 4 = x8 (or 2 NVMe)
Slot 5 = x8 (or 2 NVMe)
I wonder how in practice it will turn out with people being able to run those 4 dimms at that speed. It's got to be a good strain on the IMC.
Also is it crazy to have this much RAM that's not ECC?
