Supermicro X9DRI-LN4F+ DIMM Slots: Specs & Config Guide 2026

The Supermicro X9DRI-LN4F+ motherboard boasts 16 DIMM slots in dual-socket LGA 2011 design, supporting up to 2TB DDR3 ECC RDIMM/LRDIMM. Ideal for 2026's enterprise servers handling AI workloads and virtualization, this board remains relevant via legacy upgrades.

Explore slot layout, population rules, and optimization for peak bandwidth.

DIMM Slot Layout & Capacity

Dual 8-slot banks per CPU (CPUS 1/2). Slots labeled P1-DIMMA1 to A8, B1-B8.

Max: 16x128GB LRDIMMs for 2TB. Free slots depend on config—start with quad-channel.

Optimal Memory Configuration Rules

Balance for performance:

  • Populate matching kits per channel.
  • CPU1 first for single-socket.
  • Mix RDIMM/LRDIMM? No—pick one.
  • Speed: Up to 1866MHz with both CPUs.

2026 tip: Hybrid configs for HPC.

Installation & Troubleshooting

Power down, ESD protect. Fill A1/B1 first.

Issues: No POST—reseat. Beeps—incompatible mix.

2026 Upgrade Paths & Benchmarks

Pair with Xeon E5-2600 v3. Benchmarks show 20% bandwidth gain in full populate.
