Intel DZ87KLT-75K – The Last Intel Motherboard

Intel DZ87KLT-75K – The Last Intel Motherboard

Since the Core i7-4770K chip is only compatible with LGA 1150 socketed
boards, Intel sent us another product in their review kit. The
DZ87KLT-75K motherboard is the latest from Intel featuring the Z87
chipset and LGA 1150 socket to support Haswell processors. Before going
into detail, i’d like to mention that the board would also be the last
which Intel manufacture’s on their own. Don’t worry though since
partners of Intel would keep on making their own motherboards while
Intel focuses on more important tasks. Following is the official
statement by intel:
We disclosed internally today that Intel’s Desktop
Motherboard Business will begin slowly ramping down over the course of
the next three years. As Intel gradually ramps down its motherboard
business we are ramping up critical areas of the desktop space including
integration of innovative solutions for the PC ecosystem such as
reference design development, NUC and other areas to be discussed later.
The internal talent and experience of twenty years in the boards
business (which until recently has been largely focused on desktop tower
type designs) is being redistributed to address emerging new form
factors — desktop and mobile – and to expand Intel’s Form Factor
Reference Design (FFRD) work and enable our partners to develop exciting
new computing solutions.
The Desktop segment continues to be a major focus for Intel with
hundreds of products across many subsegments and applications. Intel
expects the broad and capable DT motherboard ecosystem (ie Asus,
Gigabyte, MSI and many others) to fully support Intel’s growing roadmap
and large worldwide customer base. Intel’s Desktop Motherboard Business
will not develop any new Intel branded desktop motherboards after
completion of Haswell-based 4th gen Core launch products in 2013 and
will continue to support all products sold through the warranty period
included with the specific product.
Intel remains very committed to the desktop business. We are making
significant investments in the enthusiast platform with our K SKU
portfolio and new 3rd Gen Intel Core Extreme Processors. In fact,
Intel’s roadmap includes 227 desktop SKUs at 34 different price points,
offering desktop solution for a wide range of customers… Intel will
continue to support a broad portfolio of CPUs, on 3 different sockets,
including LGA 2011, LGA 1155/1150, and BGA parts for entry level
platforms. We maintain a broad portfolio of desktop products, covering 5
different power envelopes. Future product roadmaps will be evaluated
based on platform performance and power needs.

Unboxing the DZ87KLTT-75K Motherboard

Back to the board itself, the DZ87KLT-75K falls under Intel’s Extreme
series brand featuring the cool Extreme series skull logo on
the packaging and heatsink. The front of the cardboard package has a
black design with a theme similar to the Haswell CPU package.

The back of the box provides labels to the key components and
features of the Intel motherboard. It comes with three years warranty,
SLI, Thunderbolt, CrossFireX support. You can also see the new Visual
BIOS interface for easier overclocking that we will detail later in this

The motherboard is packed inside a anti-static sheet with both ends
held by thick polyfoam sheets. It ensures that the motherboard isn’t
damaged while carrying the box.

Below the motherboard are a variety of accessories that come with the
package. These include a Bluetooth 2.1/ WiFi 802.11 b/g/n module,
backpanel plate, front header USB cable, 2-Way SLI connector,
integration guide and the most coolest accessory which is a bundled
mouse pad with the extreme series skull logo. I have always been a fan
of the skull logo and its nice to see Intel providing enthusiasts with
an additional cool accessory free of cost.

Four DDR3-DIMM slots offer supports for upto 32 GB of memory with
native speeds of 1600 MHz and 2400 MHz O.C+. We can also spot Power
On/Off and Reset switches near the memory slots.
DZ87KLT-75K_SATA (Large)
The motherboard comes with 6 native SATA 6 GB/s ports and two SATA 3 GB/s ports. The motherboard supports Raid 0,1,5,10 modes.
DZ87KLT-75K_Expansion (Large)

Expansion slots include three PCI-e 3.0 x16 slots (electrical; x8/x8,
; x8/x4/x4). There’s also three PCi-e 3.0 x1 and a single PCI legacy
DZ87KLT-75K_PCH (Large)
The PCH sits beneath a large heatsink besides which lies a mPCIe
connector which can be used for expansion card such as Wi-Fi or MSATA
SSDs. There are two Debug LEDs located beneath the motherboard.

Cooler Compatibility With LGA 1150 Socket

While Haswell processors ship with their own boxed coolers and cooler
makers providing retention brackets for LGA 1150 compatibility, it
should be noted that LGA 1150 socket is easily compatible with both
reference LGA 1150 boxed coolers and custom products.
So if you’re upgrading from LGA 1155 to LGA 1150, you can easily
equip your cooler on the latest socket from Intel without any sort of

It should be noted that due to improvements in 4th generation core
processor power efficency, the requirements for the processor’s power
supply have also been altered. Intel reccomends that the users running
the Haswell cpu platform check the list of tested PSUs for ones capable
of supporting fourth generation core processors. The list can be found
at: http://www,
From the filters at the top right of the page, set 12V2 Min Load 0A
to “Yes” to see which PSUs have been found to support the processor’s
new power requirements. By default, the DZ87KLT-75K BIOS disables
“Lowest CPU Idle power setting”. To make use of the power supplies that
meet the 12V2 Min Load 0A, you have to enable the “Lowest CPU Idle power
setting”. This option is located under the power tab section and you
must set the “Intel Dynamic Power technology” to custom in the primary
power settings section in Visual BIOS.
