Match each RAM module type and form factor to its corresponding physical pin count, operating voltage, and power/channel architectural characteristic.

DDR4 Desktop DIMM288-pin full-size module operating at 1.2V with power regulation handled entirely by the motherboard.
DDR5 Desktop DIMM288-pin full-size module operating at 1.1V with an onboard Power Management Integrated Circuit (PMIC) and dual 32-bit subchannels.
DDR4 Laptop SODIMM260-pin small form factor module operating at 1.2V designed for compact systems and laptops.
DDR5 Laptop SODIMM262-pin small form factor module operating at 1.1V featuring an onboard PMIC designed for compact systems and laptops.

Answer

DDR4 Desktop DIMM matches 288-pin full-size module at 1.2V with motherboard power regulation; DDR5 Desktop DIMM matches 288-pin full-size module at 1.1V with onboard PMIC and dual 32-bit subchannels; DDR4 Laptop SODIMM matches 260-pin small form factor module at 1.2V; DDR5 Laptop SODIMM matches 262-pin small form factor module at 1.1V with onboard PMIC.

Matching relies on recognizing form factor (DIMM for desktop vs SODIMM for portable systems), pin counts (288 pins for both DDR4 and DDR5 full-size DIMMs, 260 pins for DDR4 SODIMMs, and 262 pins for DDR5 SODIMMs), operating voltages (

1.2\text{V}

for DDR4 vs

1.1\text{V}

for DDR5), and power regulation location (motherboard for DDR4 vs onboard PMIC for DDR5).

Step-by-Step Solution

Differentiate between full-size desktop modules (DIMMs) and laptop/compact modules (SODIMMs).

Desktop DIMMs utilize 288 pins for both DDR4 and DDR5 generations, whereas SODIMMs use 260 pins for DDR4 and 262 pins for DDR5.

Form factor directly dictates physical size and pin density suitable for motherboard expansion slots.

Analyze standard operating voltages and power delivery architectures for DDR4 versus DDR5.

DDR4 operates at

1.2\text{V}

with power delivery controlled by the motherboard VRM. DDR5 operates at

1.1\text{V}

and features onboard power management via a Power Management Integrated Circuit (PMIC).

DDR5 moves voltage regulation from the system board directly onto the RAM module for improved power efficiency and signal stability.

Map each memory generation and form factor combination to its corresponding specification pair.
