• Using AMD EPYC 4th generation processor to deliver up to 50% more core count per single socket platform in an innovative air or liquid-cooled chassis.
• Enables DDR5 at 4800 MT/s memory and PCIe Gen5 with double the speed of previous Gen4 for faster access and transport of data optimizing application output.
• Optional DLC is available to more efficiently cool high-performance processors.

• Deliver more virtual machines per physical host using increased core count and higher memory footprint than previous generations.
• Improve responsiveness or reduce app load time for power users with up to 6x single-wide full-length or 2x double-wide full-length GPUs.

• Scale your storage using up to 33% more E3.S NVMe drives* and reduce your carbon footprint.
• Deliver more memory density with DDR5 (up to 6 TB of RAM) providing greater memory capacity.
• Support lower latency higher performance NVMe SSD in a hardware RAID solution helps maximize compute performance.

There are a few chassis options.

• Up to 8x 3.5" SAS4/SATA (HDD/SSD)
• Up to 12x 3.5" SAS/SATA (HDD/SSD)
• Up to 8x 2.5" SAS/SATA/NVMe (HDD/SSD)
• Up to 16x 2.5" SAS/SATA/NVMe (HDD/SSD)
• Up to 24x 2.5" SAS/SATA/NVMe (HDD/SSD)
• Up to 8x EDSFF E3.S NVMe Gen5
• Up to 16x EDSFF E3.S NVMe Gen5
• Up to 32x EDSFF E3.S NVMe Gen5

Rear drives are supported on only two Drive Bays. The 12 LFF and the 24 SFF. If rear drive bays are installed, you will not be able to install any GPUs, and some PCIe slots will be occupied.

• Up to 2x 2.5" SAS4/SATA/NVMe (HDD/SSD)
• Up to 4x 2.5" SAS4/SATA/NVMe (HDD/SSD)

The Dell PowerEdge R7625 Rack server supports up to two AMD EPYC 4th Generation 9004 Series with up to 128 cores per processor. The CPU has enhanced performance with 32MBs of L3 cache per core. Integrated I/O support for up to 128 lanes with PCI Express 5 on Dell platforms (AMD supports up to 160 I/O lanes with 2P). Perfect for the High-performance Computing (HPC) Workloads.

The R7625 has two cooling options, Air cooling or Direct Liquid Cooling (DLC) for the AMD Processors. If your system has air cooling it will have up to six High-performance Silver or High-Performance Gold hot plug fans. All GPUs need the Gold Fans installed and an L-Type Heat sink installed. The Standard heat sink is too tall.

The Optional Direct Liquid Cooling (DLC) is for required CPU SKU and/or configurations. With the DLC installed the 12 Bay Chassis will need Gold Fans installed. Also, any Socket of 400W TDP must use the DLC for cooling. 400W TDP CPUs will need the DLC. When installing the DLC you must take note of what DIMM is installed as well as what chassis. Not all systems support the DLC. Please read the Tech Manual below for all the details. There are a lot of limitations for the DLC, please read the manuals and check out the "Thermal Restriction Matrix" for more rules and guidance.

The R7625 supports up to 24 DIMMs (12 per socket), with up to 6 TB of memory and speeds of up to 4800 MT/s.

The R7625 support registered (RDIMMs) which use a buffer to reduce memory loading and provide greater density, allowing for the maximum platform memory capacity. Unbuffered DIMMs (UDIMMs) are not supported.

• Supports registered ECC DDR5 DIMMs only
• DDR4 DIMM memory is not supported.
• Memory DIMM slots are not hot-pluggable.
• Do not mix DIMM module types within a memory channel
• All must be RDIMM or 3DS RDIMM module types with same ECC configuration.
• Do not mix x4 and x8 DIMMs with a memory channel.

The PowerEdge R7625 system supports up to two 10/100/1000 Mbps Network Interface Controller (NIC) ports embedded on the LAN on Motherboard (LOM) and integrated on the Open Compute Project (OCP) cards.

• LOM: 2x 10GbE
• OCP: 4x 25GbE

There is a max of eight PCIe slots on the Dell PowerEdge R7625 Rack server. Six Full Height or Two low profile riser slots with up to 6 x16 slots. With over 13 PCIe expansion riser configurations, you are bound to find the correct configuration for your workload. If you install rear drives they will take up a few of the PCIe slots.

Up to two double-wide 300W, or six single-wide 75W accelerators. “High-Performance GOLD Fan” to be supported on all GPU configs. GPU is not supported on 12x3.5-inch configs and system configs with rear module installed. This system only has two rear drive options supported by the 12LFF and the 24SFF Chassis.

• Slot 1: 1 x8 Gen5 or 1 x8 Gen4 Full height, Half-length
• Slot 2: 1 x8/1 x16 Gen5 or 1 x8 Gen4 Full height, Half-length or 1 x16 Gen5 Full height Full length
• Slot 3: 1 x16 Gen4 Low profile, Half-length
• Slot 4: 1 x8 Gen4 Full height, Half-length
• Slot 5: 1 x8 Gen4 Full height, Half-length or 1 x16 Gen4 Full height, Full length
• Slot 6: 1 x16 Gen4 Low profile, Half-length
• Slot 7: 1 x8/1 x16 Gen5 or 1 x8 Gen4 Full height, Half-length or 1 x16 Gen5 Full height, Full length
• Slot 8: 1 x8 Gen5 or 1 x8 Gen4 Full height, Half-length

Dell’s RAID controller options offer performance improvements, including the fPERC solution. fPERC provides a base RAID HW controller without consuming a PCIe slot by using a small form factor and high-density connector to the base planar. There are cabling guides in the Manuals below for more information on how to set these up.

The system supports a Hot-Swappable Boot Device (BOSS-N1) which holds 2x M.2 NVMe SSD cards.

The system also has a slot for an Internal USB stick for booting as well. For more detailed information about the Boot Options, please read the manual below.
