I was double checking the expansion options that this processor supports and for PCI Express Revision is 2.0 and the PCI Express Configurations it supports are 1x16, 2x8, 1x8 & 2x4.
So as long as the FPGA PCIe card that you have meets these requirements there should be no problem at all.
It will be really helpful if you can get in contact with the manufacturer of the card, to check if there is a driver needed or some other specs that this card needs.
I have been actively researching every piece of information I can find. I've been to dozen's of forums, communities, outlets, and I jump on every topic that has anything to do with my concern. I have lost thousands of dollars due to this issue of Gen 3 and PCIe 3.0. The Intel X79 Chipset and the Z77 Chipset both have brought me face to face with some very serious questions and concerns and yet finding an open door where people are eager to say, "Hey, that is me! If this guy is going to do something about it, then count me in!" Here is my lastest response to a question sent to me by Asus as it relates to their P9X79 WS motherboard and the advertised promised of PCIe 3.0 capability. In just the past couple of weeks Asus has tagged an even smaller notification regarding PCIe 3.0 capability and the need for necessary components. Asus is now saying that the CPU not only needs to be REV. 3.0 but also must be 22nm. Up until this point I was moving towards my last attempt to salvage something of this "wasted" generation of components, by buying the only Asus product that advertises compatibility with the XEON E5-1660, which is Rev 3.0 capable. The on-sight Asus rep at the "egg" has been in contact with me and assured me that this was the one "safe" road. But when I recently asked about 22nm and what that meant, my question was met with a question. For the X79 Motherboards there is no such product known to consumers that are below a level 25 clearance with the National Security Agency! Here is my reply:
I specifically want to know if I place the $1,100 XEON
E5-1660 CPU into the ASUS P9X79 WS 2011 socket, because the XEON E5-1660 is not
a 22nm CPU, does this mean that this CPU, although listed as compatible with
the Asus P9X79 WS motherboard, will NOT ENABLE THE PCIe 3.0 that is advertised
as only capable of working provided the right components are used?
I have an EVGA GTX
680 FTW+ 4GB PCIe 3.0 certified Graphics Card. I have an ASUS P9X79 WS PCIe 3.0 Capable Motherboard.
I have an Intel XEON E5-1660 certified
REV 3.0 capable CPU.
BUT this NEW 22nm additional requirement added to the ASUS
X79 WS, which can now be found on the outside cardboard sleeve of the box- in
the upper right hand corner of the front of box, along with Intel's insistence
that ONLY INTEL GENERATION 3 CPU's will enable true PCIe 3.0 capability, has
forced me to return TWO purchases of these motherboards.
The ASUS P9X79 WS I purchased from Amazon actually had its
listed features of the motherboard changed; reading PCIe 2.0 X 16 capable and
had removed the once mentioned PCIe 3.0. PCIe 3.0 was not to be found anywhere
in the Amazon advertisement of specs.
I brought this change to the phone representative’s attention
and she checked your Asus site and matched up the discrepancies and notified
the Amazon technical team. Within one hour the specs read: PCIe 3.0 X16 as it
had before, but the very next day it was gone and replaced by PCIe 2.0.
This has forced me to sell at a considerable loss, an unused
ASUS P9X79 PRO motherboard as I kept it beyond the 30 period being told that a
resolution was coming.
I sold my Intel Sandy Bridge E 3930K CPU as I was unable to
get GEN 3 readings using utilities such as GPU-Z.
I am now looking to sell my $1,100 Intel Xeon E5-1660, which
was new and now used, as I was told it would work with the ASUS X79 PRO.
There currently is no way I can afford any more financial
loss by being told it is worth "trying" the XEON E-1660 on the Asus
P9 X79 WS motherboard. For once I open that Asus X79 WS motherboard I will not
be able to return it to the seller and avoid a restocking fee because it is
When Intel, Asus (and all X79 Intel Chipset motherboard
producers), Evga (and all NVidia based 600 Kepler graphic card producers), and NVidia
( the provider of all necessary support such as drivers), all became, by choice
or by deception, involved in creating an advertised promise that was literally
impossible to fulfill, I at this point can only do what is financially
expedient; sell as much as I can as fast as I can of any components that are
directly or indirectly tied to “Area X79”.
When the Intel Roadmap disappear into what I call "AREA
X79" one thing became glaringly obvious; an entire generation of
components from motherboards to video cards, and to CPU’s were all financial “interim”
money-makers supporting the weight of Moore’s Law, until a justified and
sensible line of products were shipped to consumers around the world.
I have lost money on the sale of an unused but
"tested" $570 Intel 3930K CPU.
I have lost money on the sale of a brand new, but tested
Asus P9X79 PRO motherboard.
I have lost money having purchased an Evga GTX 680 Graphic
Card worth $560, as it will never run in an X79 Motherboard slot at full
potential during the entire course of what is the typical life-span of a “new
line” of graphic cards.
When the day finally comes where there is a ”rebranded” X79
motherboard with a truly “Native and Functional” PCIe 3.0 X 16 slot and enough
additional other neglected promises obscured by the PCIe 3.0 mystery, such as
lots of “native USB 3.0” ports, and X79 Chipset supported SATA 6GB/sec hard
drive ports, and the disappearance of so many unfamiliar manufacturer
names who’s products were substituted for
the “real thing”, just what will this nearly 2 years of wasted hopes, supported
by wasted money on a wasted generation of components, in hindsight have to say?
When one of the most praised and promised future-proof 2011
socket is finally matched with what will emerge from “AREA X79”- the expected
and long-awaited Intel CPU which will contain the “mystery key”, making it the
final and available necessary component for every PCIe 3.0 advertised promise, will
it be both a tick and a tock which together might be enough to restore a hope
for long-awaited magical expectations of
so many heart-broken as well as financially-broken enthusiasts, gamers, work-at-home
high-end users, and your faithful and loyal build-it-yourselves consumers?
Yes of course it will work. It is and always has been a part
of the trusted Intel Roadmap. But will it do more than just work? All of those 600 series graphic card owners
will be watching those that “stood this dance out”, dropping into newer and
better rebranded X79 motherboards, a newer and better, more powerful and faster
and cooler 700 NVidia series graphic card; cards with a new architecture,
motherboards with features that make Thunderbolt chasers look like gold
pan-handlers arriving 10 years after the rivers and streams had surrendered all
they had to give.
And will the thrill of the pursuit of “smaller and better”
shine bright enough so that the tech specs (sunglasses) will polarize out the
sale of tried but not true, motherboards, graphic cards, and CPUS?
