PowerEdge R760xs

The Dell - Alienware R760xs is engineered for dependable scale with 2× Intel Xeon Scalable 4th Gen processors, 8 memory channels per CPU and an 8‑DIMM slot topology capable of supporting up to 4 TB Reg ECC RDIMMs (1 TB with current Kingston parts) using DDR5 RDIMM ECC.

Why IT teams choose Proven Match™: we convert controller rules and system topology into deterministic upgrade kits that install cleanly, train at the correct frequency, and avoid unsupported mixes—so upgrades behave like OEM and deliver predictable results in production.

• CPU Sockets: 2 × Intel Xeon Scalable 4th Gen.
• Channels per CPU: 8.
• DIMM Slots: 8 total (up to 2 DIMM(s)/channel).
• Memory Type: DDR5 RDIMM ECC.
• Controller speeds: 1DPC up to 5600 MT/s; 2DPC typically 5200 MT/s.
• Max capacity: 4 TB Reg ECC RDIMMs (1 TB with current Kingston parts).
• Last reviewed (freshness): 2026-02-12.

Speed behavior (what to expect): the CPU’s memory controller determines the real memory bus speed — at 1 DIMM per channel platforms commonly reach up to 5600 MT/s and at 2 DIMMs per channel many controllers step to ~5200 MT/s for stability; kit listings show configured speed, not just the DIMM label.

Bank Schema (population map)

• Fastest (1DPC): populate one DIMM per channel across both CPUs for maximum per‑channel bandwidth.
• Balanced (2DPC): add the second DIMM per channel mirrored across sockets to preserve symmetry and capacity scaling.
• Maximum: fill remaining slots symmetrically for total capacity.

Proven Match™ only surfaces controller‑safe, topology‑compliant configurations so you don’t end up with unstable or unsupported mixes.

Compatible Memory Types & Rules

• Curated DDR5 RDIMM ECC modules from Samsung, Micron, and Hynix are selected for Proven Match™ kits.
• Zero‑mix policy: we never mix RDIMM with LRDIMM and we enforce symmetric densities per channel to honor controller and JEDEC topology rules.
• ECC is required for server workloads; unsupported combinations are filtered out of the catalog before you buy.

Validation Tokens (what we check)

Every Proven Match™ kit must pass three independent validation gates before it appears in the catalog:

1. JEDEC DDR5 compliance.
2. Intel Xeon Scalable 4th Gen controller rules for 1DPC/2DPC.
3. OEM slot topology verification.

Only kits that pass all three are sold — stable, balanced, and performance‑true.

Mid Tier — predictable capacity and bandwidth for:

• Virtualization (higher VM density)
• Databases / OLTP
• Application servers
• Streaming ETL

Max Tier — for latency‑sensitive, memory‑heavy compute:

• In‑memory analytics (Spark / Arrow)
• AI/ML fine‑tuning and smaller training jobs
• ERP consolidation
• Large VDI deployments

Outcome‑oriented upgrades: choose the Proven Match™ tier that delivers the capacity and bandwidth scaling you need without surprises.

Pick your target: Fastest (1DPC) or Largest (2DPC/Max). Every kit shows real‑world configured speed and carries the Proven Match™ stamp so installs are smooth and predictable.

• Lifetime warranty
• Advance replacement
• Server‑savvy support
