ADATA Value 16GB (DDR5-4800, CL40) Desktop RAM

Description

16GB Single-Stick DDR5 — Dual-Rank Configuration

The AD5U480016G uses a 2048×8 dual-rank IC configuration — two ranks of DRAM chips on a single module, allowing the memory controller to interleave between ranks for improved effective memory bandwidth. This is a meaningful topology advantage over the 8GB’s single-rank 1024×16 arrangement, particularly in workloads with high memory access parallelism. At 16GB in a single slot, it’s the most capacity-efficient single-DIMM DDR5-4800 entry point in this range.

DDR5 Platform Features

All DDR5 architectural advantages carry through to the 16GB variant. ADATA DDR5 memory modules deliver frequencies of up to 4800MT/s and feature bandwidth of 38.4GB/s — 50% higher than DDR4-3200 — with the maximum frequency increased 1.63 times compared to DDR4. On-die ECC provides additional protection against single-bit errors inside DDR5 arrays, and the built-in Power Management IC (PMIC) delivers enhanced power supply stability. Operating at 1.1V, it is 8% more power-efficient than DDR4.

Performance Profile

The AD5U480016G runs at DDR5-4800 (PC5-38400) with CL40-40-40-77 timings at 1.1V via JEDEC specification — no XMP profile, no BIOS configuration required. Speed is natively achieved at DDR5-4800 on any compatible platform straight out of the box.

⚠️ No XMP on this module: DDR5-4800 is achieved via JEDEC specification natively — no BIOS tuning required.

DDR5 Platform Requirements

DDR5 is not compatible with DDR4 motherboards or slots. DDR5 U-DIMM modules have the same dimensions and pin count as DDR4 modules, but the most obvious difference is the position of the fool-proof notch — DDR5 also integrates I/O resistors with CMD/ADD resistors. DDR5 requires a DDR5-capable motherboard and CPU — Intel 12th generation Alder Lake or later on a DDR5-compatible board, or AMD Ryzen 7000 series (AM5) or later.

⚠️ DDR5 is not compatible with DDR4 slots: Verify that both your motherboard and CPU support DDR5 before purchasing. Many Intel 12th and 13th gen boards were available in both DDR4 and DDR5 variants — confirm your specific board’s memory type before ordering.

8GB vs 16GB Value DDR5-4800

The 16GB AD5U480016G delivers double the capacity of the 8GB AD5U48008G in a single slot, using a dual-rank (2Rx8) configuration vs the 8GB’s single-rank (1024×16) arrangement. For systems targeting 16GB total in a single slot, the 16GB variant is the more efficient choice; for 16GB dual-channel configurations, two 8GB sticks may be preferred.

⚠️ Single stick = single channel: For dual-channel bandwidth, install a second AD5U480016G in your motherboard’s recommended paired DIMM slots. Refer to your board’s manual for the correct slot configuration.
