Workstation DDR5 RDIMM kit

This V-color OC R-DIMM kit provides 64GB of DDR5 memory across four 16GB registered modules. It is built for W790 workstation motherboards and includes ECC error correction for data integrity in professional workloads.

Platform and voltage check

The modules operate at 1.4V and require a motherboard with W790 chipset support for registered DIMMs. Verify that your board accepts 288-pin RDIMMs and that the BIOS can apply the Intel XMP profile for the rated 6600MT/s speed.

Sustained-load behaviour

A built-in thermal sensor monitors module temperature across the 0 to 85°C operating range to prevent overheating during extended sessions. Premium 10-layer PCBs and rigorously tested Hynix ICs maintain signal integrity under continuous heavy throughput.

Questions about this item

What comes in the box and do I need anything else?

The kit contains four 16 GB DDR5 RDIMM modules for a total of 64 GB. Each module has a heat spreader and the memory uses Hynix ICs on a 10-layer PCB. No extra parts are required for installation on a compatible W790 workstation motherboard.

How do I decide between the listed speed and latency figures?

The modules run at 6600 MT/s with timings of 34-46-46-92 at 1.4 V via Intel XMP. That single rated profile is the only version offered, so choose it when your W790 board supports DDR5-6600 and you want the highest factory overclock with ECC registered operation.

What does 6600 CL34 mean once the RAM is in my W790 workstation?

At the rated 6600 MT/s the CAS latency is 34 cycles, giving low access delay for registered ECC workloads. The modules operate at 1.4 V and include an on-board thermal sensor rated for 0-85 °C, so sustained workstation tasks stay within safe thermal limits.
