Workstation ECC DDR5 kit

This V-color TR516G66S834O kit provides 128GB of DDR5 memory across eight 16GB registered DIMMs. It is built for W790 workstation motherboards and supports ECC error correction. The modules are not compatible with standard desktop PCs or laptops.

Registered design with thermal sensor

Each 288-pin RDIMM uses a 1Rx8 organisation with SK Hynix ICs on a 10-layer PCB. A built-in thermal sensor monitors operating temperatures from 0 to 85°C. The registered buffer and heat spreader help maintain signal integrity in multi-DIMM configurations.

XMP 6600MHz CL34 at 1.4V

The kit runs at 6600MHz with timings of 34-46-46-92 when the Intel XMP profile is enabled on a W790 platform. Without XMP the modules will operate at the standard DDR5 base frequency. Buyers needing higher capacities or lower voltages must choose a different specification.

Questions about this item

What does the DDR5 6600 (PC5 52800) rating mean for real-world throughput?

The modules run at 6600 MT/s with CL34-46-46-92 timings, delivering PC5 52800 bandwidth when the W790 workstation platform enables the Intel XMP profile.

Will these 288-pin RDIMMs fit my W790 workstation motherboard?

Yes, each 16 GB stick is a 288-pin DDR5 RDIMM with a heat spreader, designed for W790 workstation boards and not compatible with standard desktop or laptop slots.

How do I install the 8-module kit and enable the rated speed?

Populate all eight slots on the W790 board, then enter the BIOS and load the Intel XMP profile to set 6600 MT/s at 1.4 V; skipping the XMP step leaves the memory at default speeds.
