CRM Desktop Memory FAQ
Is the memory for the DFI MB330-CRM and SB330-CRM the same?
Not necessarily. While both use DDR3-1600 Non-ECC DIMMs, compatibility lists differ. Always check the product description to confirm it is validated for your specific CRM board model (MB or SB).
Can I mix a 4GB and an 8GB module?
It is not recommended. For optimal stability in an industrial setting, use identical modules (same brand, size, and specs) in matched channels if your board supports dual-channel architecture. Mismatched modules can lead to instability.
Why is Non-ECC memory specified?
DFI's CRM-series consumer-grade chipsets are designed for Non-ECC (Error-Correcting Code) memory. ECC RAM is for server boards and will not function in these desktop-oriented industrial platforms.
How do I physically install the RAM upgrade?
Power down and unplug the system. Ground yourself. Open the case, locate the DDR3 slots, release the side clips, align the module's notch with the slot key, and press firmly until the clips snap back into place. Reassemble and power on.
