Processor | 4th Generation Intel Xeon Scalable
Up to two 4th Generation Intel Xeon Scalable processors, with up to 56 cores and optional Intel® QuickAssist Technology. 8470Q and 6458Q are supported only in liquid cooling configuration. Mixing of the processors is not recommended. If a liquid-cooled processor is installed in one socket, then the second processor used must be of the same type.
- Faster UPI with up to four Intel Ultra Path Interconnect (Intel UPI) at up to 16 GT/s, increasing multi socket bandwidth
- More, faster I/O with PCI Express 5 and up to 80 lanes (per socket)
- Enhanced Memory Performance with DDR5 support and memory speed up to 4800 MT/s in one DIMM per channel (1DPC) and 4400 MT/s in two DIMM per channel (2DPC)
- New built-in accelerators for data analytics, networking, storage, crypto, and data compression
Cooling Options
The Dell PowerEdge R660 supports Liquid Cooling and Air Cooling options.
Heatsink & FansThe PowerEdge R660 system supports up to four sets of standard (STD) cooling fans or four sets of High-performance gold (HPR GOLD) cooling fans. The fan's selection is based on the TDP of the processor.
If rear drives are installed in the 10SFF Chassis you will need Gold Fans.
If you have a processor over 185W TDP then you will need the Direct Liquid Cooling Module installed.
For more information about cooling please refer to the installation manual of the R660.
Air ShroudThis system has a few cooling shrouds for specific configurations. All air-cooling configurations require a CPU shroud. You must Install a PCH shroud for no riser configuration.
The Rear drive shroud is needed for air-cooling with 2x 2.5-inch rear-drive configuration.
If you plan to install an A2 GPU, you will need to install the blank on R1p riser for correct airflow.
Memory Options
32 DDR5 DIMM slots, supports RDIMM 8TB max, speeds up to 4800 MT/s
Supports registered ECC DDR5 DIMMs only.

NOTE: If you are removing the memory module permanently, install a memory module blank if TDP >=250W. The procedure to install a memory module blank is similar to that of the memory module.
Networking OCP 3.0
The PowerEdge R660 system supports up to two Network Interface Controller (NIC) ports embedded on the LAN on Motherboard (LOM) card and up to four ports integrated on the Open Compute Project (OCP) card.
The system allows either LOM card or an OCP card or both to be installed in the system.
PCIe Riser Configuration Options
The PowerEdge R660 have a no riser option. If no risers are installed you will need to make sure the PCH Air Shroud is installed for the correct air flow.

GPU
With 3 PCIe slots on the back of the server, you have the ability to fill all 3 PCIe slots with 1 Single Wide 75W GPU. If you plan to install the A2 GPU there is a special Air shroud for it. Install A2 blank on R1p riser for FH riser configuration with A2 GPU. Only the Risers with a P on them hold GPUs.
Storage Controllers - Front PERC
Dell 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.
16G PERC Controller offerings are a heavy leverage of 15G PERC family. The Value and Value Performance levels carry over to 16G from 15G. New to 16G is the Avenger-based Premium Performance tier offering. This high-end offering drives IOPs performance and enhanced SSD performance.
