This 16 GB DDR4-2666 SODIMM module provides standard-capacity memory expansion for SIMATIC Field PG M6 programming devices and compatible IPC platforms. Factory-configured as a single 16 GB stick, it upgrades the base memory for engineering workstations running STEP 7, WinCC, and other Siemens automation software.

How does this compare to the 32 GB ECC variant?

The 32 GB module (6ES7648-3AK20-0PA0) offers twice the capacity at DDR4-3200 speed with ECC protection. This 16 GB module runs at DDR4-2666 without ECC — sufficient for most Field PG M6 engineering workflows. Choose 16 GB for standard programming and configuration tasks; step up to 32 GB ECC for large WinCC projects, data logging, or virtualized environments where memory integrity is critical.

Which devices are compatible?

Primary compatibility is the SIMATIC Field PG M6 programming device. The module uses the standard 260-pin SODIMM socket. Also compatible with selected SIMATIC IPC platforms that support DDR4 SODIMM at 2666 MT/s — verify your specific IPC model documentation for supported memory configurations.

Frequently Asked Questions

Does this module work with the IPC BX-39A?

While the BX-39A supports DDR4 SODIMM, Siemens recommends the 6ES7648-3AK20-0PA0 (32 GB, ECC) as the primary memory option for that platform. Check your IPC documentation for the validated memory module list before ordering.

Is this plug-and-play?

Yes — the Field PG M6 and compatible IPCs automatically detect the installed SODIMM and configure memory parameters. No driver installation or BIOS configuration is required. Power off the device before installation.
