32. Probe-IT Header
This header allows you to monitor motherboard voltages in real-time with a
multimeter or voltmeter. You must first connect the Probe-IT cable accessory
that comes with the Z270 Classified K to allow your multimeter or voltmeter to
attach. The pinout is listed on the motherboard – behind the Probe-IT
connector – and can also be found on the EVGA FAQ site at:
http://www.evga.com/support/faq/?f=59395.
33. Rear Panel Connectors (Figure 2)
This is the section referred to as the I/O Hub. This panel contains the
hardwired USB, Sound, and Ethernet connections. Please see Page 15 for a
component level breakdown.
* There are two numeric references for PCI-Express, one is physical, which is the actual
footprint, and the second is electrical, which is a reference of how many PCI-E lanes are
routed to the slot.
As PCI Express is designed to be a universal architecture, you can install x1 cards, such
as sound cards or USB controllers into a x16 slot. Many types of cards can use different
amounts of PCI-E lanes, while some applications use only certain parts of a card, such
as compute apps which allows a card to run off of a single PCI-E lane. This is why
there are x16 mechanical slots with x1 electrical PCI-E lane. Using the entire length of
the slot is NOT needed, nor does it have any adverse effect to have a shorter form-
factor bus card than the slot it is attached to.
