Speed
PCIe Gen3.0 is normally quoted as 8GBps per lane. Data rates will never reach these
speeds on a real device because some signalling bandwidth is used by bit encoding,
TLP, DLLP and PLP overhead. On a correctly functioning PC with a single PCIe
device connected; you should typically see measured maximum speed results shown
in the below table:
PCIe Gen3 Lane width
Expected speed
X1
985MB/s
X8
5500MB/s
The PCIe Test Card has a maximum bandwidth of 5500 MBps, so the card cannot
benchmark up to the PCIe gen 3.0 maximum x8 bandwidth of ~7880 MBps).
Electrostatic Discharge Caution
To prevent ESD damage:
•
Use an ESD wrist or ankle strap and ensure that it makes skin contact.
•
Connect the equipment end of the strap to an unpainted metal surface on the
chassis.
•
Avoid touching the adapter against your clothing. The wrist strap protects
components from ESD on the body only.
•
Handle the adapter by its bracket or edges only.
•
Avoid touching the printed circuit board or the connectors.
•
Put the adapter down only on an antistatic surface such as the bag supplied in
your kit.
Windows Installation:
Step 1
– Installing the PCIe Test card in a PC Chassis
Make sure the computer is completely off. Insert the PCIe card into a vacant PCIe
slot. When the card installed in the PCIe slot, power is provided from the ATX power
supply 4-pin peripheral connector through the ATX adapter cable which is plugged
into J52 on the PCIe Test card.
CAUTION!
ESD can damage electronic components when they are improperly
handled and can result in total or intermittent failures. Always follow ESD-
prevention procedures when installing or removing the PCIe test card.
