  • 128 GB capacity expands workstation memory for large datasets
  • DDR5 4800 speed delivers high bandwidth for demanding applications
  • ECC protection detects and corrects single-bit errors automatically
  • 1 V operation reduces power draw and heat output
  • Four 32 GB modules populate all slots in the Precision 3660

Capacity and Compatibility

This 128 GB kit contains four 32 GB DDR5 modules built for the Dell Precision 3660 tower workstation. It delivers ECC error correction at 4800 MT/s with a CL40 latency and 1.1 V operation.

Who It Suits

IT professionals upgrading a Precision 3660 for memory-intensive workloads will benefit from the validated ECC unbuffered design. Buyers who need registered DIMMs or a different form factor should look at something else.

Installation Notes

The 288-pin UDIMMs install in the workstation’s standard slots without tools. The most common issue is mixing these modules with existing non-ECC memory, which disables error correction.

Questions about this item

Does the Dell Precision 3660 tower need all four 32 GB DDR5 4800 ECC UDIMM slots free for this kit?

Yes, the 128 GB kit provides four 32 GB modules that fill every DDR5 4800 ECC UDIMM slot in the Precision 3660.

Can I keep any existing DDR5 4800 ECC UDIMM sticks while adding this 4 x 32 GB kit?

No, the Precision 3660 has only four DDR5 4800 ECC UDIMM slots, so installing the full kit leaves no room for extra modules.

How do I confirm the CL40 1.10 V DDR5 4800 ECC UDIMM kit is running correctly after installation?

Enter the system BIOS and verify that all four modules show 4800 MT/s, CL40 timing, 1.10 V and ECC enabled.
