FAQs

Q: Is this module ECC and Registered?
A: Yes. It is an ECC Registered (RDIMM) module for server platforms.

Q: Will this run at lower speeds if my CPU or motherboard does not support 5600 MT/s?
A: Yes. The module will downclock to the highest speed supported by the platform.

Q: Can I mix 2Rx4 with 4Rx4 modules?
A: Many platforms require matching rank and organization per channel. For best stability, use identical type, speed, and rank as specified by your server’s memory guide.

Q: Is this compatible with any DDR5 desktop board?
A: No. RDIMMs are for servers/workstations that explicitly support DDR5 ECC RDIMM.

Q: Can I mix different capacities with this 128GB RDIMM?
A: Some servers allow mixed capacities, but you should match DIMM type, voltage, and speed; consult your server’s population rules.
