The 6ES7648‑2AJ70‑1MA0 combines 8 GB of DDR3‑1600 capacity with ECC error correction — for SIMATIC IPCs that must handle large, data‑intensive workloads without sacrificing data integrity. The ECC mechanism corrects single‑bit errors on the fly, while the 8 GB headroom accommodates large runtime projects, extensive recipe archives, or memory‑hungry operator interface graphics.

ECC for Data Integrity

• Unbuffered ECC: each 64‑bit data word carries an 8‑bit ECC checksum — single‑bit errors are corrected, multi‑bit errors are detected, preventing silent data corruption.
• Industrial qualification: tested for 24/7 operation in the same demanding environments as the listed IPCs.

Compatibility and Installation

• Designed for SIMATIC IPCs that support ECC memory: refer to the specific IPC model documentation to confirm ECC support before ordering.
• Plug‑in installation: snap the DIMM into the 240‑pin slot — no BIOS configuration required beyond verifying ECC is enabled.
• Do not mix with non‑ECC modules.
