The R7615 puts one 4th Generation AMD EPYC 9004 processor in a 2U chassis and spends the extra height on drives, slots and accelerators rather than a second socket. Up to 36 E3.S bays, eight PCIe slots and three double-wide GPUs hang off a single CPU with twelve DDR5 channels. The sections below map Dell’s documented options and the thermal rules that come with them.

Our read of Dell’s documentation: where the R7615 is strong, and the limits worth knowing before you spec one.
Strengths
+Three double-wide 300 W GPUs from a one-socket server — one more than the two-socket R7625 is rated for.
+Storage on a par with the two-socket R7625: 36 E3.S Gen5 bays, 28 × 2.5-inch, or 12 × 3.5-inch plus four rear bays.
+Eight PCIe slots, four of them Gen5, with every riser configuration driven by the one processor.
+The same 23 processors as the 1U R6615, but with Dell’s full table: base clock, threads, default TDP, cTDP range and L3 for each.
+Supplies from 700 W Titanium to a 2400 W Platinum unit, plus 277 VAC / HVDC and −48 V DC choices.
Watch-outs
!Memory stops at twelve DIMMs and 3 TB, exactly as in the 1U R6615 — the extra height buys no extra memory.
!GPU builds exclude the 12 × 3.5-inch front and any rear drive module, and liquid-cooled systems take only the single-wide A2 or L4.
!With the 12 × 3.5-inch front, 400 W-class processors are not supported on air and the 300 W class is rated at 30°C.
!On 100–120 V the 2400 W supply falls to 1400 W, and the 700 W and 1800 W units need 200–240 V.
!Dell’s R7715 comparison lists the R7615 as air-cooled only, whereas the R7615 guide offers optional Direct Liquid Cooling.

The chart uses each processor’s default TDP; the cTDP ranges Dell prints are 200–240 W, 240–300 W, 320–400 W, 340–400 W and 360–400 W.
Dell’s processor overview puts Genoa at up to 128 PCIe 5.0 lanes on its platforms, and notes that AMD quotes 160 lanes for two-socket systems.
Air-cooled builds take a 2U standard or extended heat sink depending on processor and front; GPU builds use the 1U extended heat sink.
Some combinations in the thermal tables carry a 30°C inlet rating instead of the standard 35°C.
03 — Memory
12 DDR5 DIMM slots
Twelve DDR5 RDIMM slots on the single processor, one per channel — 3,072 GB with 256 GB modules. Dell lists modules rated at up to 6400 MT/s and clocks them all to 4800 MT/s.

Sizes are 16, 32, 64, 128 (dual- or quad-rank) and 256 GB; the supported-DIMM table has no 96 GB module, although the thermal tables carry a 96 GB row.
Unbuffered DIMMs are not supported, and every module runs at 1.1 V.
Twelve DIMMs is also the one-processor figure for the two-socket R7625, which reaches 24 with both sockets fitted.

Nine supplies, fitted as a 1+1 pair: 60 mm units from 700 W to 1800 W and an 86 mm 2400 W Platinum, plus a 1400 W 277 VAC / HVDC unit and an 1100 W telco DC unit.
AC277 VAC / HVDC−48 V DC
At 100–120 V the 2400 W supply delivers 1400 W and the 1100 W and 1400 W supplies 1050 W; the 700 W and 1800 W need 200–240 V.
Cords differ by unit: the 2400 W needs a C19 lead and the 1800 W a C15, which a C13 lead can reach through a C14-to-C15 jumper; the 277 V / HVDC model uses Dell’s APP 2006G1 cable and the other AC units take C13.
The PSU rating table heads the 1800 W column “Platinum”; Dell’s other tables call it Titanium.
The rating section describes up to two AC supplies, although the option list also includes the −48 V DC unit.

R7515 → R7615 → R7715
Dell’s R7615 guide compares it with the R7515, and the R7715 guide with its EPYC 9005 successor. The R7715 table credits the R7615 with up to four Gen5 slots and air cooling only; the R7615 guide adds four Gen4 slots and optional DLC.
The R7615 is the one-socket half of Dell’s 16G AMD 2U pair; the R7625 adds a second socket and twelve more DIMM slots. The 1U R6615 and R6625 draw on the same EPYC 9004 family, the EPYC 9005 R7715 follows, and the Intel R760 shares the 2U height.

GPU builds need High-performance Gold fans, the GPU shroud and the 1U extended heat sink, and rule out rear drive modules and 12 × 3.5-inch fronts. On 100–120 V each 2400 W supply is limited to 1400 W.
VDI is one of Dell’s named workloads for the R7615, and the A16 is among the double-wide cards its GPU table lists, three at most. A 32-core 9354P, 1.5 TB of memory and SAS SSDs on the 16-bay front for user profiles complete the host.

Twelve 20 TB SATA disks reach the 240 TB Dell quotes for the 3.5-inch front, and the rear module adds four SAS SSDs for metadata or a landing zone. A 16-core 9124 from the 240 W class is enough for a backup repository and keeps the 35°C rating with this front-and-rear combination.

The 12 × 3.5-inch layouts take a PERC adapter or HBA in a PCIe slot, the rear module needs riser configuration 6, 7, 9 or 10, and GPUs are not supported with this front. Dell’s matrix also lists a rear 4 × E3.S option here, but its thermal tables give no rating for that pairing.
Thirty-two front and four rear E3.S Gen5 drives, all direct-attached on S160, is the largest drive count Dell lists for the R7615. A 48-core 9454P and 1.5 TB of memory suit a scratch tier or a software-defined object store.

Dell’s matrix pairs this layout with S160 software RAID and no PERC, so any redundancy comes from software. Rear modules need riser configuration 6, 7, 9 or 10, and the thermal tables label their 32 × E3.S rear column as a 2.5-inch module rather than E3.S.

12 — FAQ
R7615 questions, answered from the documentation
What is the maximum memory of the Dell PowerEdge R7615?
Three terabytes, or 3,072 GB as Dell writes it. Twelve DDR5 RDIMM slots — a single DIMM on each of the processor’s twelve channels — take 256 GB modules at most. The module list reaches 6400 MT/s, but every DIMM is clocked to the 4800 MT/s the processor supports.
Which processors does the R7615 support?
Twenty-three EPYC 9004 models, including the 9654P, 9554P, 9454P and 9354P and the large-cache 9684X, 9384X and 9184X. They span 16 to 128 cores, 2.20 to 4.10 GHz base clock and 200 W to 400 W default TDP.
How many GPUs does the R7615 support?
Up to three double-wide 300 W cards or six single-wide 75 W cards. Dell’s GPU tables name the NVIDIA A2, A16, A30, A40, A100, H100, L4 and L40 and the AMD Instinct MI210. GPUs are not supported with 12 × 3.5-inch fronts or rear drive modules, and liquid-cooled systems take only the single-wide A2 or L4.
How many drive bays does the R7615 have?
Thirty-six, counting 32 EDSFF E3.S Gen5 drives at the front and four more in a rear module, all direct-attached on S160. For 2.5-inch storage the top layout is 24 front plus four rear, and a twelve-bay 3.5-inch front can also take a four-bay rear module.
How many PCIe slots does the R7615 have?
Up to eight — four Gen5 and four Gen4 — across fourteen riser configurations, all run by the one processor. Riser configuration 4-2 provides three double-wide full-length slots for GPUs.
Which power supplies can the R7615 use?
Nine, run as a 1+1 redundant pair. The AC range covers 700 W to 2400 W; a separate 1400 W Titanium unit accepts 277 V AC or 336 V DC, while the telco option delivers 1100 W from −48 to −60 V DC. On 100–120 V the 2400 W drops to 1400 W and the 1100 W and 1400 W units to 1050 W.
How big and heavy is the PowerEdge R7615?
A 2U chassis, 86.8 mm tall by 482 mm across, measuring 772.13 mm deep with the bezel and 758.29 mm without. Fully populated it weighs up to 34.5 kg; without drives and supplies, 25.7 kg.
Why choose the R7615 over the R7625?
The R7615 has one socket and 12 DIMM slots (3 TB); the R7625 has two sockets and 24 slots (6 TB). The R7615 takes three double-wide GPUs to the R7625’s two, and its processor list includes P-suffix models that the R7625 list does not.
What changed in the R7715?
Per the R7715 guide’s comparison, the successor keeps one socket but uses EPYC 9005 parts of up to 160 cores, and memory doubles to 24 DIMM slots at 5200 MT/s. Front storage reaches 40 E3.S drives while the rear bays go, every one of the eight slots is PCIe Gen5, GPUs step up to three 400 W double-wide cards, the largest supply is 3200 W, and iDRAC10 takes over management.
Is the Dell PowerEdge R7615 end of life?
No end-of-sale or end-of-support date appears anywhere in Dell’s R7615 technical guide. The guide’s services chapter points instead to Post Standard Support, which Dell describes as extending hardware support past the initial seven years of ProSupport by up to five years. Dates Dell publishes appear in our end-of-life checker.
