What is on this page

97 listings: 61 Hypertec and 36 CIARA (10 KRONOS, 15 HORIZON, 5 ASTRO, 4 CRIUS and 2 ARIUS), each offered as single modules and matched kits. DDR4 G5 platforms are listed twice, once for RDIMM and once for LRDIMM, so pick the form factor that matches what is already installed. DDR4 LRDIMM pages carry 64GB and 128GB modules with kits to 2TB, and up to 4TB on the ORION RS520D. DDR5 server pages run from 16GB modules to 4TB kits on the larger compute and GPU chassis; 32-slot AI servers such as the TITAN GS680R-G7 carry 16-module kits. KRONOS 545 and 546 workstation pages carry 16GB to 128GB RDIMMs in kits of up to 8, for 1TB. Machines that accept both ECC and NON-ECC UDIMM (KRONOS 540-G2, 540-G3 and 540-G4, HORIZON D12760/T12760, D12770/T12770, T12780 and T15760, and ORION W215R-G6) are listed twice, once per type, and each page links to its counterpart. DDR5 UDIMM pages carry 16GB and 32GB modules, plus 48GB where the machine's maximum allows, in kits of up to 4; DDR4 HORIZON pages carry 8GB, 16GB and 32GB. ASTRO, ARIUS and CRIUS pages carry SODIMMs as single modules and 2-module kits (single modules only on the one-slot CRIUS CO100), with 48GB modules on the 96GB-capable models.

Choosing the right module

Match the form factor first, then the generation. Hypertec servers and KRONOS 545 and 546 workstations take ECC RDIMM (or LRDIMM on DDR4 G5 platforms); ORION W215R and W210R workstations, KRONOS 540 workstations and HORIZON desktops take UDIMM; ASTRO micro PCs, ARIUS all-in-ones and CRIUS laptops take NON-ECC SODIMM only. These types are not interchangeable: never install RDIMM or LRDIMM in a UDIMM or SODIMM machine, or the reverse. Hypertec G5 and G5C systems take DDR4-3200, G6 systems take DDR5-4800, DDR5-5600 or DDR5-6400 depending on the CPU fitted, and G7 systems take DDR5-6400. RDIMM and LRDIMM cannot be mixed in the same system, so on a DDR4 G5 platform stay with whichever type is already populated; LRDIMM is the route to the highest total capacity, RDIMM the lower-cost route at moderate capacity. On machines listed with both an ECC and a NON-ECC UDIMM page, choose one type and do not mix them; on AMD Ryzen based HORIZON and KRONOS models, ECC operation depends on the processor installed. CIARA lists DDR5-6400 and faster on its Intel Core Ultra machines; those speeds apply to CUDIMM and CSODIMM, which NEMIX RAM does not currently supply, so those pages carry standard JEDEC DDR5-5600. The ARIUS 13580 is built on two main boards: the page here fits the Q670 version with DDR5 SODIMM, not the H610 version with DDR4. Populate channels in matched sets and keep densities consistent across a channel. If the installed CPU is rated below the module speed, the system clocks the memory down to the supported speed. If you are unsure which listing applies, send us the machine model and the part number on an installed module and we will confirm fitment before you order.
