When the RAM slots of your SIMATIC IPC are maxed out and you need more headroom for a growing WinCC application or a local database, the 6ES7648-2AL81-0QA0 adds 32 GB of DDR4‑2666 memory without any configuration effort. It is a Siemens‑qualified non‑ECC DIMM that fits the exact memory‑expansion slots of the listed IPC models, so you can insert it, close the case, and let the system recognise the extra capacity immediately — no BIOS tweaking, no compatibility hunting.

Compatibility & Installation

• Tested and released for SIMATIC Box IPC627E, IPC847E, Panel IPC677E, IPC647E, Field PG M5, and IPC RC620E.
• Plug‑in installation: the DIMM mates with the standard 288‑pin socket on the IPC motherboard.
• Non‑ECC, single‑rank — matches the memory architecture of the supported IPC models.
