Setting Up SLI and PhysX
SLI and PhysX are NVIDIA developed technologies supported by EVGA
motherboards. SLI is a means of dividing the graphical load between multiple video
cards, similar in theory to how dual- or quad-channel memory works, or even how
RAID0 works. However, the software (e.g. game) needs to support SLI to gain from
this technology.
PhysX is an NVIDIA technology that can be assigned to a graphics card or CPU for
programs supporting NVIDIA PhysX. As long as the PhysX driver is installed, which
occurs during a normal NVIDIA GeForce driver installation, the system will allocate
resources to support PhysX based on CPU or GPU load. You may, however, go into
the NVIDIA Control Panel and dedicate the CPU or a GPU to this function manually.
For a complete list of NVIDIA PhysX supported titles, please see this link:

SLI requires two or more video cards that support SLI; have the same GPU family
(GTX 2080 Ti, GTX 980, etc.); have the same memory type (GDDR6, GDDR5X, etc.),
volume (11GB, 8GB, etc.), and datapath width (128bit, 256bit, 384bit, etc.). SLI also
requires a motherboard that supports SLI, and an SLI or NVLink bridge for each card
in SLI. Providing the above conditions are met, compatible graphics cards with
different GPU and/or memory clock speeds will not prevent SLI from being enabled.
Note:
For questions and concerns regarding NVIDIA Surround™ and full setup instructions,
please see

. As the possible combinations of setups between SLI, monitors, and
cabling are far too vast to label in this manual, also see

walkthrough.
Installation:
1. Physically install your graphics cards, then install an SLI or NVLink bridge; examples
include a Flexible bridge (included with this motherboard), an EVGA HB Bridge or
NVLink Bridge. Current NVIDIA graphics drivers support 600 Series cards up through
GTX 2080 Ti and Titan RTX cards. Driver support is determined by NVIDIA; please
check GeForce.com to confirm compatibility with drivers and SLI.
