Memory Memory speed on the R440 ranges from 1866 to 2666 MT/s depending on installed DIMM type and configuration, with the default set to the highest speed common to both CPUs and DIMMs. DIMM type DIMM ranking Capacity DIMM rated voltage, speed RDIMM 1R/2R 8 GB, 16 GB, 32 GB DDR4 (1.2 V), 2666 LRDIMM 2R 64 GB DDR4 (1.2 V), 2666 PCIe Expansion Cards Expansion card riser PCIe slots on the riser Height Length Link Riser 2 (LOM riser) Slot 1 Mezz Type Mezz Type x8 Right riser Slot 2 (R1) Low Profile Half Length x16 Slot 2 (R1A) Full Height Half Length x16 PCIe passive bridge Slot-integrated Low Profile Half Length x8 Internal PERC riser Slot-integrated Low Profile Half Length x8 Left riser Slot 3 (R2) Low Profile Half Length x16 Riser 1A (Config 1) Riser 1 (Config 2) Riser 2 (Config 2) Boot Options Non-virtualized OS setups are best paired with BOSS, while virtualized environments run better on IDSDM. IDSDM or vFlash card The IDSDM with vFlash module sits in a dedicated rear-chassis slot, using a Dell EMC-proprietary PCIe x1 slot with a USB 3.0 interface. On the PowerEdge R440, card size moves from SD to microSD, supporting 16GB, 32GB, or 64GB for IDSDM and a fixed 16GB for vFlash, with a write-protect switch built directly onto the module. Boot Optimized Storage Subsystem (BOSS) As a fast, alternate location for OS installation, BOSS keeps drive-based storage dedicated to data rather than the operating system. This RAID card handles up to two 6Gbps M.2 SATA drives via an x8 connector on PCIe Gen2 x2 lanes, available only in low-profile, half-height form factor. Storage Controller Options Combining PERC 11 adapters (H750, H350, HBA350i) with prior-generation adapters (H740P, H730P, H330, HBA330) in the same system isn't supported.
