Dell Pro Max Slim memory kit

This 128 GB kit contains four 32 GB DDR5 modules built for the Dell Pro Max Slim desktop. Each stick runs at 5600 MHz with a CL46 latency and operates at 1.1 V. The non-ECC unbuffered design matches the platform's standard memory controller.

Four-slot population

The 288-pin UDIMM form factor fills all four slots on the motherboard, leaving no empty sockets for later expansion. Dual-rank 2Rx8 organisation increases density per channel without requiring registered or ECC support. Installation follows the board's standard DIMM sequence.

Sustained workload behaviour

Operating at the JEDEC 1.1 V baseline keeps power draw stable during long rendering or virtualisation sessions. The absence of a heat spreader means airflow from the chassis fans is the only cooling path. CL46 timing remains consistent as temperatures rise inside the compact Dell chassis.

Questions about this item

Does the CL46 latency become a bottleneck during sustained heavy workloads?

CL46 is the rated CAS latency for this DDR5 5600 kit; actual throughput under load depends on the Dell Pro Max Slim memory controller and cooling.

How much heat does the 1.1V 2Rx8 kit produce when running all day?

The modules operate at 1.10V without a heat spreader; thermal output is managed by the system's airflow and the Dell chassis design.

What Dell Pro Max Slim configuration is needed for this 288-pin UDIMM kit to work?

The desktop must support DDR5 5600 UDIMM memory with four slots and accept 2Rx8 non-ECC unbuffered modules at 1.10V.
