128GB Quad-Channel DDR4 Kit

This A-Tech kit supplies 128GB of desktop memory across four 32GB modules. It targets workstations and high-end PCs that benefit from large capacity for virtualization, content creation or heavy multitasking. Each module runs at the standard DDR4 voltage of 1.2V.

Fits Standard 288-Pin DIMM Slots

The modules use the 288-pin UDIMM form factor and are unbuffered, non-ECC memory. They install directly into four compatible motherboard slots to enable quad-channel operation where the platform supports it. No heat spreader is fitted, leaving maximum clearance for large CPU coolers.

CL22 Timing at 3200MHz

Tested at 3200MHz with a CAS latency of 22, the kit operates within standard DDR4 power limits at 1.20V. The low voltage and absence of a spreader keep thermal output modest during sustained workloads. Acoustic impact is negligible because the modules have no moving parts.

Questions about this item

What CAS latency does the kit run at when all four 32 GB modules are populated?

The kit is tested at CL22 timing across all four 32 GB DIMMs running at DDR4 3200 speed.

How much heat and power should I expect from this quad-channel kit during continuous operation?

Each module operates at the standard 1.2 V DDR4 voltage without a heat spreader, so thermal output stays within normal DDR4 limits for sustained workloads.

Which motherboard feature must already be present for this 128 GB kit to function?

Your board needs four DDR4 288-pin DIMM slots that support quad-channel operation and 32 GB per slot density.
