In the comfortable environment of an air-conditioned office, any RAM will do. But put a computer inside a traffic control box in Arizona, or a 5G base station in Norway, and standard RAM will fail.
The ADATA Industrial AD4WS3200732G22-BSSCI is engineered for exactly those extremes.
It is a 32GB DDR4-3200 SODIMM rated for Wide Temperature operation (-40°C to +85°C). Beyond just handling heat and cold, it features fixed-BOM control (likely using premium Samsung ICs) to ensure long-term stability for industrial projects.
This guide decodes the complex part number and highlights the compatibility traps you must avoid.

1. Decoding the Part Number
ADATA Industrial part numbers contain the entire spec sheet. Here is the breakdown for AD4WS3200732G22-BSSCI:
| Code Segment | Meaning | Detail |
|---|---|---|
| AD | Brand | ADATA Industrial. |
| 4 | Type | DDR4 SDRAM. |
| WS | Form Factor | Wide-Temp SODIMM. (Standard temp is usually just 'S'). |
| 3200 | Speed | 3200 MT/s (PC4-25600). |
| 732G | Capacity | 32GB. The '7' implies 16Gb (2048M x 8) IC density. |
| 22 | Latency | CL22 (Standard JEDEC timing). |
| BSSCI | Suffix | Bulk / Samsung IC / Single Rank? / Commercial? / Industrial Grade. |
Note: The suffix "BSSCI" confirms the use of high-quality ICs (Samsung) and the Industrial temperature screening.
2. Technical Specs: Built for Extremes
1. Wide Temperature (-40°C to +85°C)
Standard consumer RAM crashes below 0°C or above 85°C. This module is tested to start up in freezing conditions (critical for outdoor kiosks) and operate in fanless enclosures where internal temps can soar.
2. Fixed BOM (Bill of Materials)
For industrial certification, you cannot change components halfway through production. ADATA guarantees that the chips (Samsung), PCB, and resistors used in this part number will remain consistent, preventing "silent updates" that break compatibility.
3. Anti-Sulfuration
Industrial RAM often includes sulfur-resistant resistors. This prevents the "Black Screen of Death" caused by corrosion in factories with high pollution or sulfur gas (e.g., tire manufacturing, oil & gas).
3. Compatibility Alert: 16Gb Die Density
This is the #1 reason for returns.
The "732G" code indicates that this 32GB stick is built using 16Gb (Gigabit) DRAM chips.
- The Problem: Older memory controllers (CPUs) were designed when the maximum chip size was 8Gb. They literally do not know how to address a 16Gb chip.
- Compatible Systems: Intel 6th Gen (Skylake) and newer; AMD Ryzen (Zen) and newer.
- Incompatible Systems: Intel Bay Trail / Cherry Trail (Atom), some older Xeon E3 v3/v4.
Check your datasheet: If your Industrial PC uses an old Atom or Celeron processor, you likely need a module built with 8Gb dies (which would be Dual Rank 16GB max, or Quad Rank if supported).
4. Why "Industrial Grade" Matters
Why pay 3x the price of a consumer stick?
- 30µ Gold Plating: Consumer RAM has thin gold plating (3-10µ) on the connector pins. Industrial RAM uses 30µ gold to prevent fretting corrosion caused by vibration and thermal expansion/contraction.
- Underfill (Optional): Some variants offer underfill to glue the chips to the PCB, protecting against shock and vibration (check specific BSSCI datasheet for confirmation).
- Longevity: Guaranteed availability for 5-10 years, ensuring you can buy spares in 2030.
5. Sourcing & Replacements
Industrial memory supply is stable but specialized.
Direct Replacements:
- Innodisk: M4S0-AGS1QCEM (32GB Wide Temp).
- Apacer: 76.D305G.D360B (Industrial 32GB).
- Samsung: M471A4G43AB1-CWE (Original Samsung 32GB module, though strictly "Commercial Temp").
Sourcing Tip: Always request the "BSSCI" suffix specifically. A generic "ADATA 32GB" might get you a commercial stick (SGN) which will fail in your thermal chamber test.
6. Conclusion
The ADATA AD4WS3200732G22-BSSCI is a critical component for ruggedized computing. By combining massive 32GB capacity with -40°C tolerance, it enables Edge AI and heavy data processing in the harshest environments on Earth. Just ensure your CPU supports 16Gb density before you buy.
