WaterRam 32GB DDR4 Kit

Thermaltake WaterRam CL-W252-CA00SW-A is a 32GB kit of four 8GB DDR4 modules rated at 3200 MT/s with CL16 timings. The sticks run at 1.35V and carry RGB lighting that syncs with motherboard software. Intel XMP 2.0 profiles are supported for one-click setup.

Liquid-cooling ready RGB memory

Builders who want integrated liquid-cooling channels on their DIMMs will appreciate the WaterRam design. Users needing standard air-cooled modules or lower-voltage JEDEC-only operation should consider other kits. The RGB sync works with major motherboard ecosystems for unified lighting.

Straightforward DIMM installation

Insert the 288-pin modules into the correct motherboard slots and enable the XMP profile in BIOS to reach 3200 MT/s. Common issues include forgetting to enable XMP, mixing with slower kits, or blocking the liquid fittings with large CPU coolers.

Questions about this item

What motherboard slot does the 288-pin DDR4 WaterRam kit require?

The modules use the standard 288-pin DDR4 DIMM slot, so a motherboard with four DDR4 slots is needed to install all four 8 GB sticks.

Can the 1.35 V DDR4 3200 CL16 modules run with older DDR4 DIMMs at lower speeds?

Yes, the kit will downclock to match the slowest installed DDR4 memory, though mixing timings and voltages may require manual BIOS adjustment for stability.

How do I confirm the kit is running at DDR4 3200 with 16-18-18-38 timings after enabling Intel XMP 2.0?

Check the memory tab in CPU-Z or the BIOS memory information screen; it should show 3200 MT/s and the 16-18-18-38 timing row when XMP 2.0 is active.
