What is the maximum memory of the Dell PowerEdge XE7740?
Thirty-two DDR5 RDIMM slots reach 4 TB with 128 GB modules, running at 5200 MT/s with two per channel. One module per channel keeps 6400 MT/s and gives 2 TB with 128 GB parts. Dell also sets minimums by GPU count: eight H200 NVL, H100 NVL or RTX Pro 6000 cards need at least 1.5 TB.
Which GPUs does the XE7740 support?
Up to eight double-wide PCIe cards at up to 600 W — NVIDIA H100 NVL, H200 NVL, L40S or RTX Pro 6000, or Intel Gaudi 3 — or up to sixteen single-width NVIDIA L4s. They sit on a PCIe Base Board behind four PCIe switches, and double-wide cards go into the four middle odd-numbered slots (25–31) before the outer ones (21, 23, 33, 35).
Does the XE7740 support NVLink?
Yes, through bridges on the NVL cards. H100 NVL pairs use three 2-way bridges each, six for four cards and twelve for eight, while H200 NVL uses one 4-way bridge per four cards. Dell advises bridging only cards under the same processor. There is no NVLink baseboard as in SXM systems such as the XE8640.
Which processors does the XE7740 support?
Three Intel Xeon 6 6700P P-core models: the 6747P (48 cores, 2.7 GHz, 330 W), 6767P (64 cores, 2.4 GHz, 350 W) and 6787P (86 cores, 2.0 GHz, 350 W). Two are always fitted, and all three are rated for 35°C inlet on HPR Platinum fans.
How many network slots does the XE7740 have for a GPU cluster?
Eight Gen5 x16 full-height, half-length slots for adapters of up to 150 W each, plus one Gen5 x8 OCP 3.0 slot. Dell’s port table lists add-in NICs up to 1 × 400GbE or 2 × 200GbE and a B3220 DPU with 2 × 200GbE, while OCP cards top out at 2 × 100GbE.
What power supplies does the XE7740 need?
Eight hot-plug supplies in two zones: two for the CPU tray and six for the GPU zone, with at least one required in each. Options are 3200 W Titanium (2900 W below 220 V), 2400 W Titanium and 3200 W for 277 V AC or 336 V DC. Eight 600 W GPUs on 2400 W units need all eight supplies and cannot use A/B grid.
How many drives does the XE7740 hold?
Eight EDSFF E3.S Gen5 NVMe SSDs at the front, up to 122.88 TB, plus a BOSS-N1 boot module with two M.2 NVMe drives in RAID 1. There are no rear bays and no PERC or software RAID option.
How big, heavy and loud is the XE7740?
It is 4U: 174.3 mm high, 482 mm wide and 899.56 mm deep with the bezel, weighing up to 71.35 kg, which puts it in Dell’s server-lift class. Dell measured up to 10.3 B of sound power at 35°C and advises against acoustically sensitive locations, recommending ear protection.
How does the XE7740 differ from the XE7745?
The XE7745 keeps the same dimensions, GPU slots and power zones but uses two AMD EPYC 9005 processors of up to 192 cores and 24 DIMM slots for 6 TB. Its GPU list adds the AMD Instinct MI350P and RTX Pro 4500 and drops Gaudi 3. The XE7740 has 32 DIMM slots and Intel Xeon 6.
Is the Dell PowerEdge XE7740 end of life?
Dell’s XE7740 guide (Rev. A04, April 2026) publishes no end-of-sale or end-of-support date. Our end-of-life checker shows Dell’s dates once they appear.
