PCIE capability issuse of 3rd-gen-core CPUs

[idata]

hi

i am developing a FPGA PCIE card. the PCIE end-point controller is Xilinx 7 series integrated block, the configuration is GEN2 x8

i use the mother board which is ASUS P8Z77-M PRO, an Intel Z77 chipset.

both 2nd-gen-core CPU, a Pentium G620 and Core I3 2120 work fine with the Xilinx FPGA PCIE controller, (link GEN2 x8)

however, the system cannot find the PCIE end-point while using a 3rd-gen-core CPUs Pentium G2010.

is there any solution to fix the issue? i am afraid the 2nd-gen-core CPUs are out of the date, there may be a big issue if there is some capability issues between Xilinx FPGA PCIE controller and Intel 3rd-gen-core CPUs

thanks for the supports!!

Hi Yilei,

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 nota 22nm CPU, does this mean that this CPU, although listed as compatible withthe Asus P9X79 WS motherboard, will NOT ENABLE THE PCIe 3.0 that is advertisedas 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- inthe upper right hand corner of the front of box, along with Intel's insistencethat ONLY INTEL GENERATION 3 CPU's will enable true PCIe 3.0 capability, hasforced 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 andhad removed the once mentioned PCIe 3.0. PCIe 3.0 was not to be found anywherein 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 notifiedthe Amazon technical team. Within one hour the specs read: PCIe 3.0 X16 as ithad 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 aresolution 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 AsusP9 X79 WS motherboard. For once I open that Asus X79 WS motherboard I will notbe able to return it to the seller and avoid a restocking fee because it isopened.

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 choiceor by deception, involved in creating an advertised promise that was literallyimpossible to fulfill, I at this point can only do what is financiallyexpedient; sell as much as I can as fast as I can of any components that aredirectly 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 ofcomponents 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 andsensible 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 fullpotential during the entire course of what is the typical life-span of a "newline" 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 enoughadditional other neglected promises obscured by the PCIe 3.0 mystery, such aslots of "native USB 3.0" ports, and X79 Chipset supported SATA 6GB/sec harddrive ports, and the disappearance of so many unfamiliar manufacturernames who's products were substituted forthe "real thing", just what will this nearly 2 years of wasted hopes, supportedby 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 expectedand long-awaited Intel CPU which will contain the "mystery key", making it thefinal and avail...
