128 GB of DDR5 memory in eight 16 GB modules running at 6800 MT/s with CL34 timing and RGB lighting
This 128GB kit contains eight 16GB DDR5 modules rated at 6800 MT/s with CL34 timings. It targets desktop builders who want high capacity on Intel B660 or Z690 platforms. The unbuffered DIMMs support both Intel XMP 3.0 and AMD EXPO profiles for one-click configuration. RGB lighting and a black heat spreader complete the visual package.
Each module runs at 1.40V with the integrated heat spreader dissipating heat during normal operation. The black aluminium cover keeps temperatures in check without active cooling. RGB LEDs draw minimal additional power. Noise remains silent because the kit has no moving parts.
Under continuous workloads the 34-44-44-84 timings hold at the rated 6800 MT/s across all eight modules. The unbuffered design maintains stability without registered buffering overhead. Voltage stays at 1.40V during extended sessions. The heat spreader handles prolonged thermal load without throttling.

Insert each 288-pin stick into the motherboard slots until the latches click, then enable the Intel XMP 3.0 or AMD EXPO profile in BIOS so the kit runs at DDR5 6800 CL34 instead of the default JEDEC speed.
The unbuffered DDR5 modules have no user-serviceable parts; keep the black heat spreaders dust-free and ensure the 1.40V supply remains stable — if a module fails, replace the single 16GB stick rather than the full set.
The 1.40V operating voltage and 34-44-44-84 timings mean thermal throttling or stability loss will occur before bandwidth saturation if case airflow is insufficient for the eight RGB heat-spreader modules.
