32GB DDR4 SODIMM kit for HP ProBook

This 32GB kit contains two 16GB DDR4 2400MHz SODIMM modules built for HP ProBook 640 G3, 640 G4, 645 G4, 650 G3 and 650 G4 notebooks. The modules run at 1.2V with CL17 timing and use unbuffered, non-ECC 260-pin chips. It is aimed at owners of those specific models who need the maximum factory-supported memory.

Two matched modules enable dual-channel operation

The pair is tested together so both sticks operate at the same 2400MHz speed and 17-17-17 timings. Using a matched kit avoids the instability that can appear when mixing separate modules of different rank or latency. No heat spreaders are fitted, keeping the profile low enough for tight ProBook chassis.

Fills both slots for 32GB total capacity

The ProBook models listed support a maximum of 32GB across two sockets, so this kit occupies every available slot. It suits heavy multitasking, large spreadsheets and virtual machines that benefit from the full 32GB. Systems limited to 16GB or a single socket cannot use the full kit.

Spurningar um þessa vöru

Will the 2Rx8 DDR4 SODIMM chips need replacement after years of daily use?

The kit uses standard unbuffered DDR4 modules rated for 1.2 V operation with no moving parts, so no scheduled replacement is required under normal conditions.

What limit appears first when both 16 GB sticks run at DDR4 2400 continuously?

The platform caps memory speed at DDR4 2400 with CL17 timing, so bandwidth is fixed regardless of load duration.

How much heat and power do the two 1.2 V modules generate during all-day workloads?

Each stick runs at the standard DDR4 1.2 V without a heat spreader, producing minimal heat and drawing only the power needed for CL17 operation.
