Workstation DDR5 ECC Kit

This V-color TR532G64D832Q kit provides 128 GB across four 32 GB DDR5 R-DIMM modules rated at 6400 MHz CL32. Registered ECC circuitry and on-board thermal sensors protect data integrity under sustained workloads. The kit is validated for Intel W790 workstation platforms.

Not for consumer desktops

Buyers building standard desktop PCs or laptops cannot use this memory because it requires a W790 workstation motherboard with registered DIMM support. Systems lacking ECC registered memory capability should select unbuffered consumer modules instead.

6400 MHz CL32 XMP profile

The decisive specification is the DDR5 6400 speed with 32-39-39-102 timings at 1.4 V under Intel XMP. Confirm that your W790 board supports this frequency and voltage before purchasing.

Questions about this item

Will the ECC registered DIMMs need any firmware updates or chip replacements over their service life?

No firmware updates or chip replacements are required; the modules use SK hynix ICs on 10-layer PCBs and carry a limited lifetime warranty.

What thermal limit is reached first when the kit runs at 6400 MHz continuously?

The built-in thermal sensor monitors each module up to the 85 °C operating ceiling before throttling can occur.

How much power does the 1.4 V kit draw and how loud is the cooling under all-day load?

The modules run at 1.4 V with a passive heat spreader, so they add no fan noise and draw only the power needed for the rated speed.
