01 — Overview
The R770 at a glance
Our read of Dell’s documentation: where the R770 is strong, and the limits worth knowing before you spec one.
Strengths
+Forty front E3.S Gen5 bays plus four at the rear; Dell puts the front alone at 2457.6 TB raw.
+Room for two double-wide GPUs at up to 450 W, H200 NVL and RTX Pro 6000 included, or six single-width L4s.
+In builds without GPUs, Dell’s air-cooling tables clear all 23 processors at 35°C inlet in every storage layout, 350 W parts included.
+Eight Gen5 slots (six at x16), two OCP 3.0 bays and a 3200 W Titanium supply for the heaviest configurations.
+A front-I/O version with B35 blind-mate power rails for racks serviced only from the cold aisle.
Watch-outs
!No 3.5-inch bays, no SAS and no hard disks: Dell’s drive list is E3.S NVMe, 2.5-inch NVMe and 2.5-inch SATA SSDs, where the R760 offered 12 × 3.5-inch.
!Double-wide GPUs need riser configuration 6-2 or 11-2 with HPR Platinum fans, and none are supported with the 40-bay E3.S front.
!H200 NVL and RTX Pro 6000 are power-capped to 450 W here and need Ubuntu 24.04.02 with kernel 6.11 or later, plus a minimum iDRAC version.
!Rear drive bays exist only in riser configuration 14, and a chassis uses front risers or rear risers — never both.
!Weight varies more than the headline figure suggests: Dell’s comparison gives 28.53 kg, but its weight table reaches 32.08 kg for 24 × 2.5-inch SATA builds.

23 supported processors, mapped
The R770 takes the same 23 Xeon 6 processors as the 1U R670 — six E-core and seventeen P-core models — but its 2U airflow changes the picture: in non-GPU builds Dell’s tables cool every one of them on air. The chart plots each by core count and TDP.

Without GPUs, processors use HPR Silver fans in most layouts and HPR Gold fans with the 16, 32 and 40 × E3.S fronts, all rated for a 35°C inlet.
Heat sinks follow TDP and GPU presence: without rear GPUs, a 1U standard heat sink below 200 W and a 2U extended one from 200 W; with a GPU shroud fitted, 1U extended up to 250 W and L-type above 250 W.
Direct Liquid Cooling is optional, and Dell states it imposes no thermal restrictions on any processor.
Dell’s processor tables record turbo only as a yes/no entry, and both sockets must carry the same model.
03 — Memory
32 DIMM slots, 16 per processor
Thirty-two DDR5 RDIMM slots in eight channels per socket, the same arrangement as the R670. Large modules carry a cooling cost here: Dell requires High-performance Gold fans whenever 128 GB or 256 GB DIMMs are fitted.

With CXL 2.0 cards in riser configuration 7, a P-core R770 filled with 32 × 96 GB reaches 4608 GB using four cards of 4 × 96 GB. With 32 × 128 GB and 128 GB cards the total is 6144 GB, which Dell listed as post-launch.
8 TB means 32 × 256 GB on P-core processors at 5200 MT/s. The 6700E parts are limited to 32 GB or 64 GB DIMMs and 1 TB per socket.
CXL needs every native slot filled, at least four DIMMs on each card and no more than two cards per processor.
All listed modules are rated at 6400 MT/s, though Dell notes the processor may run them more slowly.
04 — Storage
11 drive-bay layouts, up to 44 bays
Twelve internal layouts, from diskless to 40 E3.S Gen5 bays with four more at the rear. The 2.5-inch options top out at 24 SATA bays, or 16 SATA plus 8 NVMe, and the whole list is solid-state — there is no 3.5-inch cage and no hard-disk support.

Rear E3.S bays need riser configuration 14, and Dell’s thermal tables pair them with an extra rear fan.
Front PERC H965i, H365i or H975i controllers provide RAID (ESXi needs 9.0 or later for the H975i); external shelves use the PERC H965e or HBA465e, and there is no software RAID.
The operating system can boot from a BOSS-N1 DC-MHS RAID 1 pair of M.2 NVMe drives, an M.2 interposer board or internal USB.

Riser configurations 6-2 and 11-2 are Dell’s GPU-ready layouts. BlueField-3 DPUs go in configurations 1, 2, 6-2 or 11-2 and need a full-length riser.
iDRAC shared-NIC redirection works only from the OCP card in slot 10 (rear I/O) or slot 38 (front I/O).
For rear-I/O cabling at 25 Gb and above, Dell calls for passive DAC or active optics with an 85°C rating.
The front-I/O chassis has no bezel option, and Dell pairs it with B35 blind-mate power rails.
06 — Power & cooling
11 power supplies, 800–3,200 W
Eleven supply options in two sizes: 60 mm units from 800 W to 1800 W, and 73.5 mm units at 2400 W and 3200 W. Two are fitted, 1+1 redundant or non-redundant 1+0 / 2+0, and Dell marked three of the eleven as arriving after the September 2025 launch.
AC277 VAC / HVDC
The 3200 W Titanium supply is high-line only: it delivers 2900 W at 200–220 V and 3200 W at 220.1–240 V, and it uses a C19 lead, as does the 2400 W unit.
Low-line (100–120 V) ratings drop to 1400 W for the 2400 W unit and to 1050 W for both the 1100 W and 1500 W units.
For 277 VAC / HVDC sites there are 3200 W and 1500 W Titanium units on APP / Saf-D-Grid cords; telco racks get a 1400 W −48 to −60 V DC supply.
H200 NVL and RTX Pro 6000 builds need slot-specific GPU power cables, which Dell identifies by part number for slots 2 and 7.

The 128 GB DIMMs call for HPR Gold fans. The CXL route needs riser configuration 7 and every DIMM slot filled, is not in the configurator, and its 6144 GB version was post-launch. A Universal backplane order also needs a SAS/SATA drive for full factory validation, so we confirm the eight-bay backplane when we quote.

12 — FAQ
R770 questions, answered from the documentation
What is the maximum memory of the Dell PowerEdge R770?
Thirty-two DDR5 RDIMM slots take the R770 to 8 TB with 256 GB modules, which require P-core processors and run at 5200 MT/s. Keeping one DIMM per channel for 6400 MT/s limits a build to 16 modules, or 2 TB with 128 GB parts. Dell’s CXL option adds memory cards on top of 96 GB or 128 GB DIMMs for 4608 GB or 6144 GB.
Which GPUs does the R770 support?
Six NVIDIA models: up to six single-width L4s, or two double-wide H100 NVL, L40S, A16, H200 NVL or RTX Pro 6000 cards. The H200 NVL and RTX Pro 6000 are capped at 450 W in this server and need HPR Platinum fans, a minimum iDRAC version and Ubuntu 24.04.02 with kernel 6.11 or later.
How many drive bays does the R770 have?
Up to 44 E3.S Gen5 NVMe bays: 40 at the front and four at the rear with riser configuration 14. For 2.5-inch drives the maximum is 24 SATA bays, or 16 SATA plus 8 NVMe. There are no 3.5-inch bays.
How many PCIe slots does the R770 have?
Up to eight PCIe Gen5 slots, six of which can be x16, fed by 88 PCIe 5.0 lanes per processor. Dell documents eleven riser configurations, and a chassis uses either front or rear risers. The two OCP NIC 3.0 bays are in addition to that slot count.
Which processors does the R770 support?
The same 23 Xeon 6 processors as the R670: six 6700E E-core models with 64 to 144 cores and seventeen 6700P/6500P P-core models with 8 to 86 cores, from 150 W to 350 W. Without GPUs, Dell’s tables air-cool all of them at up to 35°C, and liquid cooling is optional.
What power supplies does the R770 use?
Eleven are listed: 800 W, 1100 W and 1500 W units, 1800 W high-line, 2400 W and 3200 W Titanium, 1400 W −48 V DC, and 1500 W or 3200 W units for 277 VAC / HVDC. The 3200 W supply gives 2900 W at 200–220 V and needs a C19 lead.
How big and heavy is the PowerEdge R770?
It is 86.8 mm high and 482 mm wide. Depth is 802.40 mm with the bezel in the rear-I/O build (801.51 mm without) and 814.52 mm for front I/O, which takes no bezel. Dell’s weight table runs from 25.89 kg to 32.08 kg fully populated, depending on the drive layout.
What changed from the R760 to the R770?
In Dell’s comparison the processors change from 4th/5th Gen Xeon Scalable, at up to 64 cores, to Xeon 6 at a maximum of 86 P-cores or 144 E-cores, and memory speed rises from 5600 to 6400 MT/s. Double-wide GPUs rise from 350 W to 450 W, all eight slots are Gen5, and the 3.5-inch and SAS layouts give way to up to 40 E3.S bays. The same table shows it 7.57 kg lighter.
How does the R770 differ from the R770AP?
The R770AP is built on the Xeon 6 6900-series — 128 P-cores and 500 W at the top — with twelve memory channels and 24 DIMM slots for 3 TB, 96 PCIe lanes per processor and NVMe-only storage, and it has no GPU support. The R770 keeps 32 slots and 8 TB, GPU options, SATA layouts and up to eight PCIe slots.
Is the Dell PowerEdge R770 end of life?
Dell’s R770 guide gives no model-wide end-of-sale or end-of-support date, and several options were still marked as post-launch in its May 2026 edition. Standard hardware warranties last one or three years depending on model, and ProSupport contracts extend them. Our end-of-life checker tracks dates once Dell publishes them.
