Speed DDR5 6800 (PC5 54400)

  • 128 GB capacity across eight 16 GB modules for large workloads
  • DDR5 6800 speed with CL34 latency for fast data access
  • ECC registered design detects and corrects memory errors automatically
  • Built-in thermal sensor monitors temperature up to 85 °C
  • Qualified on 10-layer PCB with Hynix ICs for signal integrity

Built for W790 workstations

This registered ECC DDR5 kit delivers 128 GB across eight 16 GB modules rated at 6800 MT/s with CL34 latency. It targets professionals who need maximum capacity and error correction on Intel W790 platform workstations.

Fills every slot on a W790 board

The 288-pin R-DIMM design requires a workstation motherboard with registered memory support and cannot be used in standard desktop or laptop systems. Eight modules occupy all available channels, leaving no room for further expansion.

Sustained operation up to 85 °C

A built-in thermal sensor monitors module temperature during continuous workloads, while the 10-layer PCB and heat spreader help dissipate heat at the rated 1.4 V. Testing covers voltage stability, temperature resistance and signal integrity over long runs.

Questions about this item

How hot can the V-color TR516G68S834O modules get before they exceed their rated operating temperature?

The modules are rated for an operating temperature range of 0 to 85°C and include a built-in thermal sensor to monitor temperatures and prevent overheating.

How much power will eight 16 GB sticks at 6800 MT/s draw from the motherboard all day?

Each module runs at 1.4 V; total power draw depends on the W790 workstation motherboard's VRM design and workload, so consult the board manual for sustained-load figures.

Which motherboard chipset and form factor must I already have for this 128 GB kit to function?

The kit is exclusively compatible with W790 workstation motherboards and will not work in regular desktop PCs or laptops.
