Note: Global Standard Products (GSP) are a subset of Dell’s relationship products that are managed for availability and synchronized
transitions on a worldwide basis. They ensure the same platform is available for purchase globally. This allows customers to reduce
the number of configurations managed on a worldwide basis, thereby reducing their costs. They also enable companies to implement
global IT standards by locking in specific product configurations worldwide. The following GSP processors identified below will be
made available to Dell customers.

Note: Processor numbers are not a measure of performance. Processor availability subject to change and may vary by region/
country.

• 3200MHz memory in the 7920 Towers/Rack will not run at that frequency. It will automatically clock down to the maximum fre-

Intel Optane DC Persistent Memory is offered with select Xeon Cascade Lake processors. It runs at 2666MHz and requires standard
RDIMM memory as cache— which is not included in overall memory capacity. Intel DCPMM is supported in memory mode only on the
Precision 7920 Tower and is not “Persistent” in memory mode.

Note: 2666MHz RDIMM memory used as cache in Optane DC Persistent Memory configs has transitioned to 3200MHz RDIMM
memory as part of an industry transition. However the 3200MHz memory will automatically clock down to a maximum of 2666MHz.

and Japan

Precision systems ship out of the factory with PCIe AUX graphics power connectors (dongles) as needed for the supported graphics
cards. NOTE: Dual Graphics with NVIDIA NVLink and SLI (Scalable Link Interface) options available with select cards.

power cabling and connectors . (Requires 2nd CPU to be installed).

1. 220V input/line cord with the 1400Watt PSU is required for 750-900W configurations i.e 3X RTX 5000, 6000, 8000 .
for customers in 100-120V countries (including U.S. Canada, Japan). Please note.

2. 900W configurations have the following restriction: maximum 2x 150 watt processors or no LRDIMMs

3. The 7920 Tower system ships with 3x 6+2 pin (8 pin) aux graphics power connectors (dongles). The 3rd 6+2 Pin connector is

located at top of the system with the 2x additional PCIe x16 slots which are enabled when a 2nd CPU is installed.

4. Up to 6x 6+2 dongles can be configured out of the factory as required for high end graphics cards.

5. A splitter customer kit (492-BCQP) to convert a standard single 6+2 connector dongle to two 6+2 connector dongles is available.
This is only for chassis with upgraded 8A aux power cable/dongle assemblies—look for CL in the Chassis SKU description.

6. A customer kit (470-ADUR) to upgrade older 7920 Tower chassis to 8A aux power cable/dongle assembly is also available.

POWER

NOTE: These form factors utilize a more efficient Active Power Factor Correction (APFC) power supply. Dell recommends only Universal Power

Supplies (UPS) based on Sine Wave output for APFC PSUs, not an approximation of a Sine Wave, Square Wave, or quasi-Square Wave.

1. PSUs are single rail (like servers) which means additional power can be delivered on demand to cards/subsystems as needed.

2. A safety interlock will shut down powered system 3 seconds (audible alarm) after side door is opened.

CH ASS I S ENCL O SURE & V ENT I L ATION R E QUI R E M EN T S

ENCLOSURE VENTILATION

If your enclosure has doors, they need to be of a type that allows at least 30% airflow through the
enclosure (front and back).

ENCLOSURE MINIMUM CLEARANCE

Leave a 10.2 cm (4 in.) minimum clearance on all vented sides of the computer to permit the airflow

required for proper ventilation.

ENCLOSURE DOOR AREA

The intake and exhaust door areas should be, at a minimum, the same size as the system intake and exhaust areas.

RECOMMENDED ENCLOSURE

Do not install your computer in an enclosure that does not allow airflow. This restricts the airflow and
impacts your computer’s performance, possibly causing it to overheat.

OPEN DESK MINIMUM CLEARANCE

If your computer is installed in a corner, on a desk, or under a desk, leave at least 5.1 cm (2 in.) clearance
from the back of the computer to the wall to permit the airflow required for proper ventilation.
