The R760 is Dell's flagship mainstream 2U for the DDR5 era, and memory is both its superpower and its invoice shock: thirty-two RDIMM slots across two 4th- or 5th-gen Xeon sockets, eight channels each, scaling to 8TB on 5th-gen silicon. In the 2026 shortage, populating those slots is routinely the most expensive line on the build sheet — which is why this page exists: Dell's verified rules on top, the live cross-brand market underneath, no configurator markup in between.
Every module in the table below passes the R760's documented rules — DDR5 registered ECC only, at or above the platform's operating floor — and prices refresh on the same rolling cycle as the rest of this site. The upgrade scenarios further down price real configurations against today's listings, not against what memory cost when the server was quoted.
4800 MT/s RDIMMs with 4th Gen Xeon SP; 5600/6400 MT/s with 5th Gen; operating speed reduces to 4400 MT/s at 2 DIMMs per channel, and the processor may reduce the rated DIMM speed.
Two-socket, 4th/5th Gen Intel Xeon Scalable. Max 4TB with 4th Gen, 8TB with 5th Gen. DDR4 not supported.

Operating speed depends on CPU generation and DIMMs per channel — 4800 MT/s RDIMMs with 4th Gen Xeon SP; 5600/6400 MT/s with 5th Gen; operating speed reduces to 4400 MT/s at 2 DIMMs per channel, and the processor may reduce the rated DIMM speed.. Always verify against Dell's QVL for your exact configuration.

Each scenario is priced from the cheapest compatible in-stock module at that capacity, at the timestamp above. Configurations never exceed the platform's 32 DIMM slots. Populate channels per the OEM rules below for full bandwidth.
Memory is organized into eight channels per processor (two sockets per channel), 16 sockets per processor and 32 per system. 96GB RDIMMs are not supported in 2- or 4-DIMMs-per-CPU configurations.
Speed behavior on this platform: 4800 MT/s RDIMMs with 4th Gen Xeon SP; 5600/6400 MT/s with 5th Gen; operating speed reduces to 4400 MT/s at 2 DIMMs per channel, and the processor may reduce the rated DIMM speed. Faster-rated modules from the table above are safe — they operate at the platform's supported speed for your configuration rather than their label speed.
Paraphrased from Dell's official documentation. Anything the manual does not state is omitted here rather than guessed.
Start from your CPU generation, because it decides the whole shopping list: 4th-gen Xeon configurations buy 4800 MT/s modules (the platform's rated grade), while 5th-gen owners can weigh 5600-rated parts against their premium in the live table. Then decide 1DPC versus 2DPC honestly — sixteen larger DIMMs keep the higher speed grade, thirty-two smaller ones trade a grade for capacity, and at DDR5 prices the $/GB spread between capacity tiers often decides the question the bandwidth argument started.
For a phased fleet upgrade, buy each server's full increment in one order: DDR5 listings move enough week to week that splitting a sixteen-module purchase across a quarter means paying three different prices for one configuration. The scenarios above give the live baseline; each module's linked detail page carries the 90-day chart that tells you whether today's number is a dip or a plateau.
Every specification in the rules box above was verified against the Dell document linked beneath it before this page went live — nothing is inferred from forum lore or reseller listings, and any field the document does not state is simply absent here rather than guessed. The compatibility table applies those verified rules mechanically to our tracked module catalog: generation must match, the module type must appear in the platform's allowed list, speed must meet the documented floor, and per-DIMM capacity must respect the stated maximum. What survives that filter is sorted by live $/GB — computed against true 1024-based capacities — and refreshed on the same rolling cycle as every price on this site.
Two honest limits worth stating. First, our catalog tracks the retail module market, not Dell's option-part universe — a module absent from the table is not declared incompatible, merely untracked; the rules box tells you what any candidate must satisfy. Second, a compatibility table is not a QVL: Dell validates specific part numbers against specific configurations, and the disclaimer above the table is not boilerplate but the actual final step. Use this page to find the market's honest price for compliant memory; use the vendor's QVL to bless the exact part before a production order.
R760 memory buyers usually arrive in one of three states. New deployments balancing channel population against a procurement ceiling — where the scenarios below show what each rung of capacity actually costs today. Established fleets adding VM density, where the discipline is matching what is already in the channels. And repurposed units inheriting new workloads — analytics, in-memory caching — that were never in the original spec. All three end at the same table: the cheapest compliant module per capacity tier, updated every few hours.
One R760-specific note worth the emphasis Dell gives it: 96GB RDIMMs — the non-power-of-two tier that often prices attractively per GB — are not supported in 2- or 4-DIMMs-per-CPU configurations on this platform. If your loadout is minimal, step around that tier or step up the DIMM count before using it.
Dell's documentation puts the platform maximum at 8TB across 32 DIMM slots, with single modules supported up to 256GB. Reaching the maximum requires the largest supported DIMM in every slot — most real upgrades target far less, which is what the live scenarios above price.
DDR5 RDIMM at 4400 to 6400 MT/s, per Dell's documentation. Consumer non-ECC and XMP/EXPO kits are not supported — every module in the table above is a verified ECC server part of the correct type.
Dell's stated rules: Memory is organized into eight channels per processor (two sockets per channel), 16 sockets per processor and 32 per system. 96GB RDIMMs are not supported in 2- or 4-DIMMs-per-CPU configurations. Mixed speeds, where allowed, run at the slowest module's speed — buying identical part numbers per channel remains the safe pattern.
Yes — modules rated above 6400 MT/s downclock to the platform's supported speed and run normally, which is why the table marks them "runs at up to 6400 here". Modules rated below 4400 MT/s are excluded from the table because Dell does not list them as supported.
8× 64GB fills 512GB and leaves 24 of the 32 slots free for later growth. Fewer, larger DIMMs preserve expansion room; more, smaller DIMMs are sometimes cheaper per GB — the live table above lets you price both routes at today's numbers.
For DDR5 platforms like this one there is effectively no refurbished market yet — the fleets that would feed it are still in service. Buy new, verify the part against Dell's QVL, and use each module's 90-day price chart (linked in the table) to time the purchase.
With 5th-gen Xeon Scalable processors, yes — Dell's memory specifications list 5600 and 6400 MT/s RDIMMs for 5th-gen configurations. With 4th-gen processors the rated speed is 4800 MT/s, and any configuration drops to 4400 MT/s at two DIMMs per channel.
