01 — Overview
The R6715 at a glance
Our read of Dell’s documentation: where the R6715 is strong, and the limits worth knowing before you spec one.
Strengths
+One socket reaches 160 Zen 5 cores with the EPYC 9845; Dell’s 18-processor list starts at the 8-core, 125 W EPYC 9015 and tops out at 400 W.
+Two DIMMs on each of 12 channels give one processor 24 slots and up to 6 TB — twice the slot count of the previous-generation R6615.
+Eight storage layouts, from a diskless chassis and four 3.5-inch drives up to 20 EDSFF E3.S Gen5 bays with two more E3.S at the rear: 22 NVMe drives in one rack unit.
+Two OCP NIC 3.0 positions alongside the x16 Gen5 slots — three PCIe cards with one OCP card, or two with two — plus OCP ports up to 400 GbE and a BlueField-3 DPU option.
+Air or Direct Liquid Cooling; with DLC, Dell lists no processor thermal restrictions at all.
Watch-outs
!All 24 slots filled means two DIMMs per channel: memory falls from 5200 MT/s to 4000 MT/s with 32 GB and larger RDIMMs (4400 MT/s with 16 GB single-rank).
!The EPYC 9275F is marked not supported on air in all three layouts Dell tabulates, so it needs liquid cooling; the 9535 and 9455 are missing from the air-cooling table altogether.
!Dell does not plan CXL support on the R6715, even though the processors have it — the R6725 and R7715 both accept CXL Type 3 memory.
!There is no software RAID, and without Tri-Mode a single controller cannot serve SAS, SATA and NVMe drives together.
!The only GPU Dell names is the NVIDIA L4, three at most, and the 1800 W supply was not available at the November 2025 launch.

02 — Processors
18 supported processors, mapped
Dell’s processor table for the R6715 has 18 EPYC 9005 parts: core counts from 8 (EPYC 9015) to 160 (EPYC 9845), TDP from 125 W to 400 W, five F-suffix models and three P-suffix models — the 9355P, 9555P and 9655P. The chart plots each one by cores and TDP. Read the notes before choosing, because Dell’s cooling matrix does not agree with its processor table on every power figure.

Table 17 gives each processor one TDP; the air-cooling matrix prints a cTDP and a maximum cTDP instead. Two parts disagree: the 9335 appears there at 280 W cTDP / 300 W maximum against 210 W in Table 17, and the 9655P at 320 W / 400 W against 400 W.
The maximum cTDP runs above the processor table for the low-power parts: 155 W for the 125 W 9015 and 9115, and 240 W for the 200 W 9135 and 9255.
The 24-core 9275F is marked not supported on air in all three tabulated layouts; Dell’s accompanying note calls it a 400 W part, while Table 17 lists 320 W.
Table 17’s memory-speed column reads 6400 MT/s (6000 MT/s for the 9535 and 9455), but the R6715’s own memory tables set 5200 MT/s as the one-DIMM-per-channel speed.
Every air-cooled processor uses the C-type heat sink.
03 — Memory
24 DDR5 DIMM slots
The single socket drives 12 DDR5 channels with two slots each, for 24 RDIMM slots and up to 6 TB. Dell spells out the speed cost of that capacity: one DIMM per channel runs at 5200 MT/s, while populating the second slot drops the bus to 4400 MT/s with 16 GB single-rank modules and to 4000 MT/s with every larger size.

4400 / 4000 MT/s*
* 4400 MT/s applies to 16 GB single-rank RDIMMs; the 32, 64, 96 and 128 GB dual-rank and 256 GB eight-rank modules run at 4000 MT/s two to a channel. Every DIMM Dell lists is rated 6400 MT/s at 1.1 V.
The 6 TB ceiling needs 24 × 256 GB and therefore a second module in each channel; kept to one per channel at full speed, 256 GB DIMMs stop at 3 TB.
RDIMMs only — Dell does not support UDIMMs in the R6715.
In Dell’s air-cooling matrix, DIMMs of 96 GB and larger need HPR Silver fans in every layout, and in the 16 × E3.S chassis every DIMM size does.
Three NUMA modes are available — one, two or four domains per socket (NPS1, the default, NPS2 and NPS4) — though some processors cannot run NPS2 or NPS4.
For three L4 GPUs Dell recommends 108–144 GB of system memory, 1.5 to 2 times the GPU memory.
04 — Storage
8 drive-bay layouts, up to 22 bays
Eight internal layouts, from a diskless chassis to 20 EDSFF E3.S Gen5 bays at the front plus two E3.S at the rear. Only that last layout has rear drives, and only one riser configuration permits it. Dell’s thermal matrix tabulates just three of the eight — no backplane, 8 × 2.5-inch and 16 × E3.S.

Universal backplanes accept SAS/SATA and NVMe drives; for full factory validation Dell requires at least one of each on the order.
PowerEdge does not support Tri-Mode, so SAS, SATA and NVMe drives never share a controller, and software RAID is not offered.
Internal controllers: PERC H975i (x16 PCIe 5.0, 1 GB DDR4 and 192 MB cache), H965i (x16 PCIe 4.0, 8 GB DDR4) and H365i (x8 PCIe 4.0); external: H965e and HBA465e. The H975i needs ESXi 9.0 or later.
Every riser configuration uses a front-mounted PERC, so the internal RAID controller does not take one of the three PCIe slots.
Boot sits on a rear BOSS-N1 DC-MHS module, with an internal USB port as the alternative.

GPUs, PCIe and networking
GPU support stops at single-wide cards. Dell rates the R6715 for up to three 75 W GPUs and names one, the 24 GB NVIDIA L4. The R6715’s cooling tables give no GPU-specific rules; Dell’s general note is that the component with the lowest temperature limit sets the inlet ceiling for the whole server. Up to three 75 W single-wide GPUs (NVIDIA L4, 24 GB); DPUs: BlueField-3 B3220 (150 W) in riser configuration 3, B3140H later.

PCIe
Dell’s OCP table rates the slots at PCIe Gen5 x16, but its NIC appendix says the HPM board wires the OCP connection at x8 and an x16 card falls back to x8.
Riser configurations 2 to 6 are all single-processor builds; configuration 6 (R2s + R4a) is the only one that allows rear drives.
Dell’s weight table names two riser builds: RC4 with three x16 full-height slots, and RC5 with two x16 low-profile slots plus the second OCP card.
Beyond OCP, the R6715 accepts up to three PCIe add-in NICs (400 GbE × 1 or 100 GbE × 2) and up to two Fibre Channel HBAs at FC32 or FC64.
OCP cards reach 400 GbE by running a 2 × 200 GbE card as a single 400 GbE port.
The BlueField-3 B3220 DPU (2 × 200 GbE, 150 W) fits slot 1 in riser configuration 3; the 400 GbE B3140H was not available at launch.
06 — Power & cooling
8 power supplies, 800–1,800 W
Up to two hot-plug M-CRPS supplies in the 60 mm form factor, 1+1 redundant. Dell lists eight: Platinum and Titanium units at 800 W and 1100 W, a 1500 W Titanium, a 1500 W model fed from 277 VAC or 336 V DC, a 1400 W −48 to −60 V DC telco supply, and an 1800 W Titanium that was not offered at the November 2025 launch.
AC277 VAC / HVDC
At 100–120 V low line the 1100 W and 1500 W units are rated at 1050 W; the 800 W units keep their full 800 W, and the 1800 W supply has no low-line rating.
Dell’s comparison table lists the 1800 W supply as 100–240 VAC, but its PSU specification and rating tables give 200–240 VAC or 240 V DC only.
Every AC and 240 V DC supply, the 1800 W included, uses a C13 lead; the 277 VAC unit uses an APP/Saf-D-Grid connector and the telco unit a DC power cable.
Fit matching wattages: with mixed supplies at POST only the larger is enabled and the BIOS warns, and a supply added while running stays disabled unless it matches.
The −48 V DC unit draws up to 33 A.

R6615 → R6715
Dell’s guide sets the R6715 against the R6615, the single-socket 1U model it follows. Height and width are unchanged, depth with the bezel grows from 772.13 mm to 816.921 mm, and almost everything inside moves on.
Source: Dell PowerEdge R6715 Technical Guide (June 2026, Rev. A06), Table 2 — Comparison of PowerEdge R6715 and R6615.
The R6715 family side by side
The R6715 is the single-socket 1U member of Dell’s EPYC 9005 rack line. The R6725 puts two processors and 500 W parts into the same 1U depth, the R7715 takes the single socket into 2U with eight slots and double-wide GPUs, and the R6615 is the EPYC 9004 predecessor. The bars compare each model’s documented limits.

Software-defined storage
16-bay E3.S storage node
Software-defined storage is one of the three workloads Dell names for the R6715. Sixteen E3.S Gen5 NVMe drives give 122.88 TB raw in 1U, and a 64-core 9555P leaves cores for data services. Dell’s matrix supports this 360 W part on air at 35°C in the 16 × E3.S chassis, with HPR Silver fans.
1 × AMD EPYC 9555P — 64 cores @ 3.2 GHz, 360 W
12 × 64 GB DDR5 RDIMM — 768 GB, one per channel at 5200 MT/s
A 128-core 9745 and all 24 DIMM slots filled with 64 GB modules give 1.5 TB for VM density, accepting 4000 MT/s at two DIMMs per channel. Eight U.2 NVMe drives hold the local datastore. The 400 W processor is supported on air at 35°C in the 8 × 2.5-inch chassis with HPR Silver fans.
1 × AMD EPYC 9745 — 128 cores @ 2.4 GHz, 400 W

Keeping 5200 MT/s means stopping at 12 DIMMs (768 GB with 64 GB modules). Riser and fan choices for the exact NIC and drive mix are confirmed at quotation.
The 9175F pairs just sixteen cores, clocked from 4.2 GHz, with 512 MB of L3 cache, which keeps the licensed core count down. The eight-bay Universal backplane takes SATA SSDs behind the PERC H965i alongside two NVMe drives — and Dell requires at least one of each drive type on a Universal-backplane order for factory validation.

12 — FAQ
R6715 questions, answered from the documentation
What is the maximum memory of the Dell PowerEdge R6715?
Six terabytes, using 24 × 256 GB RDIMMs. Because one processor has 12 channels, filling all 24 slots puts two DIMMs on each channel, and Dell’s tables then run memory at 4000 MT/s. With 12 DIMMs, one per channel, memory runs at 5200 MT/s and 256 GB modules give 3 TB.
Which processors does the R6715 support?
Eighteen 5th Gen AMD EPYC 9005 models, from the 8-core 9015 to the 160-core 9845, with TDPs from 125 W to 400 W in Dell’s processor table. The list includes five F-suffix and three P-suffix models. The 24-core 9275F is not supported with air cooling, so it needs Direct Liquid Cooling.
How many drive bays does the R6715 have?
Up to 22: 20 EDSFF E3.S Gen5 NVMe bays at the front and two E3.S bays at the rear, which need riser configuration 6. The other fronts are 16 × E3.S, 10 × 2.5-inch (all SAS/SATA or with four Universal bays), 8 × 2.5-inch Universal or U.2, and 4 × 3.5-inch SAS/SATA, plus a no-backplane option.
How many GPUs does the R6715 support?
Up to three 75 W single-wide GPUs, and the 24 GB NVIDIA L4 is the only one Dell names. For three L4s Dell suggests 108–144 GB of system memory. For double-wide accelerators, look at the 2U R7715, which takes up to three.
How many PCIe and OCP slots does the R6715 have?
Three x16 PCIe Gen5 slots (1, 2 and 4) and two OCP NIC 3.0 slots (2 and 5). Slot 2 is either a low-profile PCIe slot or the second OCP card, so the choice is three PCIe cards with one OCP card, or two with two. Dell notes that the OCP connection runs at x8 on the HPM board.
Which power supplies can the R6715 use?
Two hot-plug 60 mm supplies in 1+1 redundancy, chosen from 800 W and 1100 W Platinum or Titanium, 1500 W Titanium, 1500 W for 277 VAC or 336 V DC, and 1400 W for −48 to −60 V DC. An 1800 W Titanium unit is listed but was not available at the November 2025 launch; Dell’s comparison table gives it 100–240 VAC input, its PSU tables 200–240 VAC only. On 100–120 V the 1100 W and 1500 W units are rated at 1050 W.
How big and heavy is the PowerEdge R6715?
It is 42.8 mm high, 482.0 mm wide and 816.921 mm deep with the bezel (815.141 mm without). Dell’s weight table gives 19.41 kg to 21.19 kg with every bay filled, depending on the layout, although its comparison table quotes 19.96 kg as the maximum.
How does the R6715 differ from the R6725 and R7715?
All three use EPYC 9005 and 24 DIMM slots with a 6 TB ceiling. The R6725 is the two-socket 1U model: 12 slots per processor at one DIMM per channel and up to 6400 MT/s, processors up to 192 cores and 500 W, and CXL memory. The R7715 keeps one socket but moves to 2U for up to eight PCIe slots, 40 E3.S bays and double-wide GPUs.
What changed from the R6615 to the R6715?
Dell’s comparison moves from one 4th Gen EPYC with up to 128 cores and 12 DIMM slots to one EPYC 9005 with up to 160 cores and 24 slots, with memory speed rising from 4800 to 5200 MT/s. The R6715 adds a second OCP slot and a 20-bay E3.S front, moves from iDRAC9 to iDRAC10, and drops S160 software RAID and the optional LOM.
Is the Dell PowerEdge R6715 end of life?
Dell’s R6715 technical guide carries no end-of-sale or end-of-support date, and several options in it are still flagged as post-launch additions. Official dates will appear in our end-of-life checker once Dell publishes them.
