Server memory upgrade for Supermicro H11DSi

This 16 GB DDR4 3200 ECC RDIMM is built for the Supermicro H11DSi platform running AMD EPYC processors. Registered buffering and on-die error correction keep data integrity intact under sustained server workloads. The single-module design lets administrators scale capacity one slot at a time.

288-pin registered DIMM with major-brand chips

Modules use Samsung, Micron or Hynix components tested under load for stability in mission-critical environments. CL22 latency at 1.20 V balances throughput with power draw in dense chassis. No heat spreader means the stick fits tight clearance slots without interference.

Replaces non-ECC or lower-speed DDR4 in EPYC servers

The jump is worth it when workloads demand registered ECC protection and 3200 MT/s bandwidth on the H11DSi. Systems already running 3200 CL22 registered memory gain capacity only, not speed. Buyers needing DDR5, unbuffered DIMMs or consumer desktop compatibility should look elsewhere.

Questions about this item

Does DDR4 3200 PC4-25600 run at 3200 MT/s on the Supermicro H11DSi?

The module is rated DDR4 3200 PC4-25600 CL22; actual speed depends on the EPYC processor and BIOS configuration on the H11DSi.

Will this 288-pin 2Rx8 RDIMM fit the H11DSi DIMM slots?

Yes — it is a 288-pin DDR4 RDIMM with 2Rx8 organisation, matching the H11DSi registered DIMM slots.

How do I install this ECC RDIMM and what step is often missed?

Power down, open the chassis, align the notch on the 288-pin module with the slot key, press firmly until both latches click, then verify in BIOS that ECC is enabled.
