WaterRam RGB DDR4 3200 Kit

The Thermaltake WaterRam RGB delivers 16GB of DDR4 memory in a matched 2 x 8GB kit rated at 3200 MT/s with CL16 latency. Integrated liquid-cooling channels and a full-coverage heat spreader keep temperatures low while addressable RGB lighting synchronises with motherboard software. The modules run at 1.35V and support Intel XMP 2.0 for one-click profile activation.

Upgrade From Standard Air-Cooled DDR4

This kit replaces conventional air-cooled DDR4 modules when thermal headroom or lighting integration matter. The dual-path cooling design handles sustained workloads without throttling, making the jump worthwhile for compact builds or overclocked configurations where standard heatsinks run warm.

Installation Notes

The 288-pin DIMMs seat like any unbuffered DDR4 module; enable the XMP 2.0 profile in BIOS to reach the rated 3200 speed and 16-18-18-38 timings. Common issues include leaving the profile disabled, which leaves the kit at JEDEC defaults, or mixing with mismatched modules that prevent the XMP profile from applying.

Questions about this item

Will the 288-pin DDR4 modules and liquid-cooling barbs clear my CPU air cooler?

Each stick uses a standard 288-pin DDR4 form factor with a built-in heat spreader; the liquid-cooling channels add barbs on the top edge, so measure from the motherboard slot to the cooler base to confirm clearance.

Do I need to fill and bleed the loop before the RGB lighting and XMP 2.0 profile will work?

No — the memory runs at 1.35 V with the Intel XMP 2.0 profile (16-18-18-38 at DDR4 3200) as soon as it is seated; the RGB LEDs are powered from the slot and sync via motherboard software regardless of whether the liquid loop is filled.

If coolant leaks onto the PCB years later, can the 8 GB modules be replaced individually?

The kit is sold as a matched 16 GB pair (2 × 8 GB) validated for the 16-18-18-38 timing at 1.35 V; Thermaltake does not offer single 8 GB replacements, so a leak would require replacing the full kit.
