CORSAIR Enters DDR5 Workstation Market with WS DDR5 RDIMM ECC Memory Kits

[btarunr]

Corsair today announced it is entering the DDR5 Workstation market with the introduction of a range of WS DDR5 RDIMM memory kits. Engineered to offer uncompromising performance and reliability, these ECC RDIMM kits redefine the capabilities of the newest workstations, and are compatible with the latest 4th Gen Intel Xeon and AMD Ryzen Threadripper 7000 processors.

This new range of memory kits boasts capacities of up to 256 GB, setting a new standard for memory-intensive tasks such as high-resolution media editing, 3D rendering, and AI training. Rigorously tested and carefully screened, these modules surpass JEDEC specifications with tighter timings and higher frequencies, ensuring optimal performance for the most demanding workloads.



The DDR5 registered DIMMs (RDIMMs) support Error Correction Code (ECC), enabling real-time error detection and correction for consistently reliable data processing. This commitment to stability caters to the needs of workstation users who rely on uninterrupted performance for their professional endeavors.

Achieving optimal performance is straightforward thanks to support for Intel XMP 3.0 and AMD EXPO. A few clicks to load the faster profile in the UEFI BIOS is all that's required to unleash incredible throughput on compatible hardware, making these DDR5 RDIMMs user-friendly while maintaining top-tier performance.

Understanding the diverse needs of professional users, Corsair offers a range of capacities, including 4x 16 GB kits (64 GB), 8x 16 GB kits (128 GB), 4x 32 GB kits (128 GB), and 8x 32 GB kits for a massive 256 GB of high-speed DDR5 memory. Frequencies reaching up to 6,400MT/s ensure abundant bandwidth to tackle the most resource-intensive tasks.

To help tackle the heat generated during the most intensive workloads, Corsair has integrated a PGS layer, efficiently distributing heat away from the Power Management Integrated Circuit (PMIC) and across the RDIMMs. This design ensures quality cooling and reliability even under the most demanding conditions.
Corsair WS DDR5 RDIMM memory provides professionals with the memory they need to elevate their work to new heights by getting more done in less time, all backed up by a name they can trust.

Since Ryzen also supports ECC memory, these might be interesting to people who aren't running Threadripper too. Probably want them in pairs then though, especially for ITX systems.

Ryzens support ECC U(nbuffered)DIMMs along with standard non-ECC UDIMMs, in theory anyway since the motherboard has to provide support for it, and most of them do. Intel also supports both, but only when running the workstation W680 chipset, and with certain CPU models.
DDR5 always has on-die ECC but that's not the one we're discussing. By ECC I mean DIMMs with 2 extra memory chips, due to each DIMM having two sub-channels as opposed to DDR4 and earlier which had one channel and required only 1 extra chip for ECC.
Unfortunately you can't use RDIMMs in UDIMM motherboards - they are not even physically compatible.

RDIMMs are different to UDIMMs that AMD and Intel's "mainstream/desktop" platforms run. So far there are no mini ITX Threadripper boards(give sometime for Asrock to make one) or even Xeon-W boards.

Agree very much with what you've written *except* your statement about "most" Ryzen motherboards supporting ECC. That's sadly not true. At least not when it comes to the manufacturers' own specifications. Only ASUS and ASRock claim ECC support. Gigabyte and MSI specifically do not. Most of the smaller players (NZXT, eVGA, Biostar etc) do not either.

BTW, since there now always is a form of (on-die) ECC used with DDR5 memory, what was previously referred to as ECC is now called side-band ECC.

Corsair has the worst memory in the market, one brand that fails the most, I own a computer shop and have been building since the late 90s.

You're right of course if we only consider official specifications. However from my experience some designs do connect the extra lanes to DIMMs, so they might work with ECC modules even without official support, just as with previous AM4 generation. Of course there's more to it than that - the firmware has to be complicit in full support and that requires individual testing.

It was always called that
We've just been using the short form to describe the most popular one (side-band) since the alternative modes weren't really popular before DDR5 (on-die) or LPDDR4/5 (link/inline). Certain Intel CPUs even support in-band ECC that sacrifices some capacity and performance of "normal" memory setups to add ECC protection.
