Dell PowerEdge R750

The R750 opens Dell's 15th generation: Ice Lake CPUs, DDR4-3200, PCIe Gen4 — the platform where used pricing meets near-current performance.

Knowledge pages are educational references, independent of sales inventory. Items without confirmed sourcing are reference-spec — quoted on demand.

Typical uses

Consolidation of older clusters, Gen4 NVMe storage, mainstream AI-adjacent preprocessing.

Platform at a glance

CPU support	Intel Xeon Scalable 3rd Gen (Ice Lake), 2 sockets
Memory platform	32 × DDR4-3200 slots (16 per CPU, 8 channels); up to 8TB with LRDIMM+PMem variants — 32GB DDR4-3200AA RDIMM is the volume module here
Drives & RAID	Up to 24 × 2.5" incl. NVMe-heavy variants · PERC H745/H755
PCIe & accelerators	PCIe Gen4 risers; up to 3 double-width accelerators (config-dependent)
Power & networking	Dual PSU 800W–2400W

Memory rules & limits

8-channel CPUs: populate in multiples of 8 per socket for full bandwidth. 2666/2933 modules run, but at reduced platform value.

How it compares

vs R740: +33% DIMM slots, Gen4 I/O, higher per-core performance. vs R760: 16th Gen moves to DDR5 — a different memory economy entirely.

Common buying mistakes

Populating 12 DIMMs per CPU and losing channel balance
Buying DDR4-2933 "to save money" on a 3200 platform
Ignoring Gen4 riser differences when planning NVMe

Used-unit inspection checklist

BIOS/iDRAC firmware reasonably current
Memory at 3200 in BIOS readout
PSU wattage vs planned accelerators
No bent pins on CPU sockets (if de-lidded units)
