FAQs

Q: Is x4 better than x8 for reliability?
A: Many enterprise platforms prefer x4 devices for certain RAS features; check your server’s memory guidelines for recommendations.

Q: Can I combine this 32GB module with smaller capacities?
A: Yes on many systems, but matching capacity and rank per channel is recommended for best performance.

Q: Will this run at 3200 MT/s in all CPUs?
A: Actual speed depends on CPU, memory population, and firmware; it will train to the highest supported JEDEC speed.

Q: Is this compatible with desktop systems?
A: Typically no; desktops rarely support RDIMM. Use UDIMM unless the board explicitly lists RDIMM support.
