Big DRAM capacities to tackle large language model processing

Biwin has introduced two new ultra-high-capacity 192GB (4x48GB) DDR5 memory kits to compete with the best RAM. Targeted at AI developers to boost memory-hungry AI applications, the latest kits, dubbed the Black Opal OC Lab Gold Edition DW100 RGB, are comprised of DDR5-6400 and DDR5-6000 models, both featuring a massive 192GB of capacity in total (48GB per stick). The new kits will be available starting late April on Amazon, priced at an estimated $849.

The DDR5-6400 variant comes in a CL30-39-39-108 configuration, and the DDR5-6000 spec CL28-36-36-102. Both configurations operate at 1.4V. The memory DIMMS are RGB illuminated, sporting a black and gold color scheme with clock-like logos on the sides. Both configs come with AMD EXPO profiles for easy integration on AMD systems.

The new DIMMS are advertised for AI-computing and enterprise-focused workloads, such as large language model computing, generative AI computing, and edge computing. These workloads typically benefit from large memory capacities, which these kits come with.

The DDR5-6000 spec was allegedly targeted on purpose for AMD-based systems. Due to the intricacies of the Infinity Fabric and memory controller, DDR5-6000 is widely regarded as the sweet spot for Ryzen 7000 and Ryzen 9000 CPUs. Most chips are capable of running DDR5-6000in a 1:1 ratio. Nothing was said about the DDR5-6400 spec, but more recent BIOS updates for AM5 motherboards have pushed the envelope to DDR5-6400 for many Ryzen CPUs. Inevitably, this is why Biwin created a DDR5-6400 version of its 192GB AMD-focused memory kit.

Both specs were advertised as running memory-testing applications on an AM5-based Ryzen 9 CPU (for some reason, the exact model name was grayed out). The DDR5-6000 kit ran MemtestPro for over seven hours with perfect stability. The DDR5-6400 kit ran TestMem5 for only over an hour but also yielded no errors. The screenshot for the DDR5-6400 test shows the CPU SoC voltage running at 1.26V (1.3V is considered the limit for SoC voltage on AM5 Ryzen CPUs).

The new kits are allegedly validated for compatibility on MSI and Gigabyte X870 motherboards. Nothing stops users from running these kits in other AM5 motherboards (or DDR5 Intel motherboards, even). Still, validity adds extra insurance that these kits will work out of the box without stability issues.

    not touch AM5 yet but how good are the memory controllers (overall average) vs am4 with quad sticks as i know am4 really had to cut speeds to run em frequently (by like 400 mhz in some cases)

    Given the notoriously poor nature of running 2DPC on both AMD and Intel I wonder what the success rate is using these kits. Hopefully some reviewers will get their hands on them so we can see how realistic these speeds are.

    Do they actually advertise that byline or is that your own invention?

    Because at the bandwidth this can offer, LLMs filling this capacity will be too slow to tolerate.

    It's actually to cope with Adobe's infamous memory leaks in Lightroom and Photoshop.

    Enterprise-focused workloads without ECC? 🤔

    I hear that with machine learning the fuzzyness introduced from lack of ECC is actually beneficial.

    Now only the performance barrier remains...
