Pci express status test

I ran PC-Doctor on my older HP Destop. I got the message PCI Express Status Test #7 Failure. I also was encouraged to update my graphics driver - which I did. I still get the Test # 7 Failure message. What could this mean?

X-Fi Fatal1ty PCI/-Express - All Hardware Acceleration Crashing, Significant R

Hello,
I've made a few posts on the forums recently about various topics to help me isolate the issue I am having. At this point, using the latest stable drivers for either a PCI or PCI-E X-Fi Fatalty, any hardware acceleration of sounds is causing my system to bluescreen, freeze or crash the application. Some games give me no option of not using hardware acceleration (ie. Rainbow6 Vegas 2), resorting in my having to change my Sound Acceleration down to Emulation Only. This setting greatly eases off on the sound latency buffers, resulting in sounds that are delayed an entire second. The good news is no crashes and sounds actually sound correct.
A few things to note about my setup,
) I am an extreme computer professional, programmer and developer. My Windows XP SP2 installation is incredibly streamlined; I only have 6 services running and all non-essential drivers removed, resulting in only 69MiB commit charge at startup across processes and ~950 threads. Suffice to say, my system is baby-cheek clean, and I aim to keep it that way.
2) I have been using this setup for many years now. I have been using NVIDIA video cards for the past 5+ years, currently I have a GTX280, and all of them have behaved perfectly with my streamlined setup. I even unregister every single one of NVIDIA's DLLs and stop all of their services, and the 3D Settings Per Application and Color Control Features still all work. Suffice to say, NVIDIA's drivers, although a trite on the large side, are written well enough to keep drivers away from OS services (as it should be).
3) My other hardware is not at fault. I have tested the X-Fis against multiple PSUs, different video cards, multiple fresh installations of Windows and more. I don't use utilities to clean my drivers; I do it by hand. I know exactly what's on my system and what I want removed. Though it may be egotistical to state, I'm pretty much knowledgable of every component my system has running.
4) As a result of this knowledge and my desire to keep my system clean, I ONLY HAVE INSTALLED the drivers necessary for my X-Fis to work. I DID install Creative Audio Console, but the application seems to have too many dependencies on OS Services, since it never runs, either reporting that my audio device cannot be found, or the application simply does nothing and a bogus error is written to the event log. I have enabled DCOM to make sure it wasn't dependent on that, and it still does not work. To summarize, yes, I have tried enabling every service I could find that it might depend on, and none worked. Creative Audio Console is, to me, a piece of ill-written software. In comparison to NVIDIA's excellent control panel which works no matter how much stuff I remove, Creative's Audio Console fails.
I do not have the Creative Audio Licensing Engine, I do not have the Creative Audio Control Panel, I do not have the Creative Labs Audio Engine Service, I do not have CMSS or any other OS-level services that normally get installed. Remember people, drivers are NOT TO BE DEPENDENT on OS services; they are protocols defining to the OS how to communicate with the hardware. Any necessity of additional "service" software is way past the acceptable standards of drivers.
5) That being said, I had no issues with stability using older drivers on my PCI X-Fi Fatalty cards. These drivers were dated early 2007, and did not install all of the X-Fi Effects, Utility Effects, 20x Effects, etc. drivers. Mind you I preferred these drivers since they were much simpler to track, as they only had a few .sys files.
As it stands, I want to use my PCI-Express X-Fi Fatalty, but I want to use it without all of Creative's bloat. I want streamlined, driver-only installation that does not NEED external applications to reinforce its stability. Creative, IS THAT POSSIBLE? Can someone, by definition of the Windows Driver Management signature system, just use your drivers alone for stable gaming? If not, you're violating standards and should never have received WDM cert. on any drivers. I highly recommend you do NOT spit back, saying that for proper functionality, performance, stability, etc. you must install all of Creative's supplemental software. These requires are in violation of the ethics behind software drivers and receiving Digital Signature Certification from Microsoft on your drivers.

Infinity7,
I do not want to sound arrogant, but the list of options you provided me with is the stereotypical laundry list of system configuration information for any piece of hardware. I'll address everything though.
) No, I'm not using an NVIDIA chipset. I'm using an ASuS Maximus Extreme, just like you said, which uses the X38 chipset.
2) I'm using Windows XP 32-bit, SP2. I have 2 GiB of memory and do NOT have PAE enabled.
2) I don't have onboard sound; our motherboard has a PCI-E sound card which I do not have installed.
3) I don't have any spyware. I don't browse the web on my system. I know every program running and have no rootkits. Nothing is hiding from me.
4) I don't use antivirus programs. I've been on the internet for 5+ years now and have never needed an antivirus program, since I know when I have a virus and I remove it manually.
5) I have the latest version of DirectX, June 2008 Redistritutable. Note that most of the post DX 9.0c revisions are meant for D3D, and have nothing to do with DSound.
6) I've tried every PCI-E slot I have, including both PCI-E x slots and both PCI-E x6 slots. The card is currently in one of my x6 slots.
7) Any 998+ system is going to have IRQ sharing. Between ACPI BIOSes (more IRQs), Windows XP and drivers, IRQs are rarely in conflict, aside from occasional USB device IRQ sharing. To answer your question, yes, currently both my video card and sound card are sharing IRQ 6. I have done enough work to isolate that IRQ sharing is NOT the issue, though, especially through my testing of the PCI card and the PCI-E card experiencing the same issue.
8) The output sampling rate of games is not always configurable, and never makes a difference. The X-Fi always upsamples everything it gets as it is, though I guess there is some validity to the sampling rates that are streamed into the buffers.
Now, to address the rest of your suggestions I say read my post. I specify that changing acceleration to emulation results in perfect stability and sounds that sound correct, however the relaxed latency results in sounds? that are easily delayed by second. This is unacceptable for gaming, obviously.
As for your ordering of driver installation, it really is through lack of knowledge that people state what order drivers must be installed in. Even NVIDIA's drivers probe for any change through the interfaces they use when the system starts, so any chipset drivers that drastically change the devices in Windows will be detected as changed by other drivers. Be that as it may, I didn't even have the X-Fi in my computer when I installed this latest version of Windows. Only after I had installed everything did I begin to install the Creative Drivers (whilst avoiding all bloatware).
Most importantly, note that I determined when the crashing started occuring with my original PCI version of the card. After I installed the drivers that started including the additional .sys files (X-Fi Effects, 20X effects, etc.) the crashing occured. As far as I know I cannot use older drivers with the PCI-E model, so rolling back to those previous drivers is out of the question.
Lastly, for my system specs,

Sonnet Tango PCI-Express Firewire 400/USB 2.0

Had my new Mac Pro less than a week and as I didn't want to move it out from under my desk too much I fitted an extra 500Gb HD and a Sonnet Tango PCi-Express Firewire 400/USB 2.0 card before I started it up for the first time.
If I put the Mac to sleep it won't wake (I have to restart using the power button) and the status light flashes in a '3 flash then pause and repeat' way indicating failed RAM.
I've replaced the 3x 2Gb RAM sticks (as fitted by my local Apple reseller) and replaced them with the standard 3x 1Gb as shipped… No change… I've run the AHT and Memtest and everything checks out fine there. Remove the Sonnet card and the problem is gone, I've tried the card in a different slot and the problem returns… I don't have another PCI-Express card to try… Any suggestions as how to proceed? I need those FW400 ports!

I've contacted Sonnet and they've been very helpful… They tell me that I'm the first person to report a sleep issue with this card (really?) and that I need to contact the retailer that I bought it from as it must be faulty. As yet I've had no reply from the retailer and Sonnet have offered to contact their UK rep on my behalf if I don't hear anything in the next couple of days. I'll keep you posted…

Need PCI Express Firewire

I did a search here, and on Google. The cheapest card found was $55, and that had only 2 ports. I'm not a cheapscate, but this is my first purchase for my new G5 and the last FW card I bought for my G4 was $22. Is express always that much more? I definitely need it, because I seemed to have gotten one of the Dual 2G with a bad FW port. I did all the tests and the only thing Apple will do is take the thing apart, and I'd rather not have them do that for one port.

Hi Claude;
If Apple is going to do this under warrenty, then I would strongly suggest that you allow them to do it. Personally, I think that not allowing them to fix the problem now might end costing you in the long run.
To answer your question, yes PCI Express cards are generally more expensive. It appears this is true for two reason. First PCI Express is new and new always costs more. The second reason is that generally PCI Express card have greater performance then either PCI or PCI-X.

Firewire PCI Express cards

I'm sorry if this is semi-redundant with the usb pci express card page already posted, but I was wondering if anyone knew if either of these would work on the Mac Pro:
http://www.aaxeon.com/products/Productdetail.aspx?cate=8&modelno=FWB3414#specs
http://www.macmall.com/macmall/shop/detail.asp?dpno=709052
If so, does anyone have any experience with either or know which is better? Any help would be greatly appreciated. Thank you in advance!
Mac Pro

I checked OWC and they are saying Aaxeon for any PCIe Mac (dual core, quad, and Mac Pro). SIIG is probably, as usual, just reselling and putting their name on someone else's (and probably someone else's firmware, too).
I don't like the "20MB/sec writes based on manuf's tests" part though. But I probably will pick one up nonetheless.

Anything else you think is relevant: Using a PROMISE SuperTrak EX8350 RTL PCI-Express x 4 SATA II Controller Card.
Ok, here is my problem:
I can not, for the life of me, get this PCI-Express raid card to show the raid's BIOS screen (or get my BIOS to see the controller so I can boot off it). Basically this is needed to setup the array, see the array status when the system boots, and boot off the array, etc.. If I was running windows I would be totally screwed for booting off the array but with linux I can boot off of it as I can load the kernel (only the kernel) with the drivers on it from another boot drive and boot off the array.
I had to put the raid controller in another one of my comps (had to put a PCI vid card in that one as it only had one PCI-E x16 slot) to setup the initial array. The controller works perfectly fine with this mobo (as it is detected/acessible from linux) the only problem is when my system POST's I have no way to manage the RAID array which is quite annoying. I already tried updating to the newest BIOS for my mobo and I think it is something specific with this mobo or something as I had no problems using my sister's comp which is an AM2 socket mobo (also nforce chipset) which is the same brand (MSI).
Some things I have tried already:
Upgrading to the newest BIOS version
Taking out the geforce 8600 gt and putting in a PCI vid card and trying the raid controller in each of the x16 PCI-E slots (running in x8 mode because the board is set to SLI mode (the raid controller requires atleast a x4 slot).
Any ideas or am I SOL?
Also, maybe this should be in the BIOS section?

Just thought I would mention, this board as listed as a compatible product for my mobo here:
http://global.msi.com.tw/index.php?func=prodtestreport&prod_no=1141&maincat_no=1&cat2_no=170&cat3_no=#menu
If you click on SCSI controllers it gives you a link to here:
http://global.msi.com.tw/uploads/test_report/TR2_1141.pdf
And my card is listed on the very bottom entry of that pdf file. Not having any access to the RAID controller's BIOS is pretty lame.

Problem of PCI express link width and speed

hello,
I instantiate the pci express core v1.7 into a pci express endpoint and the core was configured as GEN I x8 or GEN II x4. By using the example design Xilinx offered in the ipcore dir, I could read and write device by PIO mode.
However, when I check the device’s link width and speed by using lspci –vvvv in Linux, I found that no matter what configurations I set, the device link is always trained as GEN I x1, which means the throughput of device, reduce 8 times. May the most important problem is that all logic in the user layer upon transaction layer are written at 250MHz, and if link width and speed are limited 2.5G/T and x1, I need to change user logic circuit which is a huge work.
So my question is how to change the PCI express link width and speed in OS side, or I need to change a new motherboard?
(I guess it related with motherboard, and I check that the PCI express slot in motherboard support GEN II X16. Another issue, when I insert a PCI express GEN II x8 device, the device is also trained as GEN I x1).

2x K8N Neo 4 - PCI express problem

Hi,
I've received 2 motherboard K8N Neo4 MS-7125 and both of them have the same problem ie the PCI express seems dead (bip error indicating a video problem). When I use an old PCI video card, I've an initialization and something on the monitor but I'm unable to boot or access the bios.
Of course, I've tested both motherboards with several PCI-Express video cards, new PSU, new DDR, resetting the bios, unplugged all devices like HDD and optical drives.
I'm surprised to see two motherboard of the same type with the same failure at the same time. They are a little bit more 3years old (3y+4months and 3y+1month)
Anybody with the same problem ?
(I hope it's not a default of this K8N series as I have also this motherboard model in one of my computer )

Quote from: Svet on 04-July-09, 00:32:13
Not all PCI-E gen2 VGA's can works in PCI-E v1 slots...
The RX700 and NX6600GT were previously installed on these motherboards. They are working on another computer too.
I'm relatively sure that it's a motherboard problem in both cases.
I'm just surprised to see 2 motherboards with the same 'default' at the same time.

MSI G41TM-P31 PCI-EXPRESS X16

Hello everyone,
I am new here
i wonder what version of pci express x16 my motherboard have> ( G41TM-P31 )
I run on it an ati hd 4850 1gb
and gpu-z tells me it runs at (pci ex16 1.1 @ 1.1 x16 )
while other programs like AIDA 64 and hwinfo told me it runs at ( pci ex16 2.0 @1.1 x16)
MY PROBLEM NOW ..
i will upgrade my vga to hd 7750 which support pci ex version 3.0
i am afraid it will not run at my current mobo.
i read that if my mobo support pci-ex 2.0 it will work ..
and if it supports version 1.X , it will not work.
SO I WANT TO KNOW WHAT THE REAL VERSION OF PCI-EXPRESS X16 MY MOTHERBOARD SUPPORTS ?
and if it supports version 2.0 why my 4850 run at 1.1 in power saving and high performance modes ??
thanks in advance.

Quote from: zizomania on 27-November-12, 04:43:00
seems it is 1.1 :(
> so how HWINFO & AIDA 64 says my motherboard support v 2.0
and how i know that i have this model of g41 chipset (82G41) ?
so ... 7750 will not boot with this motherboard ?
It's v1.1 for sure.
Now talking about your HD 7750 ...
Nvidia GTX 560 is more powerful and it runs without any bottleneck on PCI Express 1.1
The main problem with many AMD (PCI-E 3.0) graphics cards is that they are NOT backwards compatible.
You need to test it and to see how it goes.

Is it possible to add an extra Graphics card: ATI X300 SE PCI express

I have a PowerMac G5 with ATI Radeon 9600 XT(AGP) installed. Recently my friend gave me a ATI X300 SE PCI express card and I am wondering whether I can add this card in the G5 and hook up another monitor to it.
The ATI and Apple websites didn't mention this card is supported, so should I just give up this idea? Thanks.

Another reason you can't use the ATI X300 -- it has Windows PC ROM code. You can only use cards in the Power Mac with OS X compatible firmware.
As of this date, the fastest AGP card you can buy to replace your old one is the Mac Edition of the Radeon X800 XT. It runs $399 from various sources (ATI online store, Apple online store, MacSales.com, SmallDog.com, and Buy.com).

Tecra M9 - PCI Express Error at start-up

Hello Everybody ..
I own a Toshiba Tecra M9 (PTM91E-04R03TEN)
http://www.toshiba.ie/innovation/jsp/supportMyProduct.do?service=IE#tab0;
On switching on,- Its Showing the Toshiba splach screen and then "PCI Express error." on a black screen
I can't get beyond this Black Screen
and I can't get into BIOS ??..
One time it did manage to boot up fully, I left it running for a while as I save information from the HDD. but then the problem started again .
I believe this is a problem with the nvidia GPU ( Fatigue cracking on the BGA )
I have the Laptop stripted down .. and have purchased ArctiClean , Thermal Pad, & Arctic Silver for the "repair"
Should I have somebody scan the hardware and to find the troublemaker ? ..OR.. should I just reflow the GPU .
I'm technically minded .. but not a PC / Laptop technican :(..
any Instruction on how to proceed would be greatfully received ..
Should i just " bung it in the oven" and see how it goes ? :) :) .
Regards,
Peter

Hi
I found and read your other post regarding this issue and in my opinion the PCI Express error is related to an PCI device (i.e miniPCI module like WLan / Bluetooth, etc ) connected to the motherboard.
Of course I cannot say for sure that this issue isnt related to a GPU malfunction.
Usually such details can be provided only by an service engineer who checked the notebooks hardware.
Generally I dont recommend to disassemble the notebook. Its very tricky to perform such procedure and of course there is always a risk of part damage doing such procedure without any instructions.

Can I add a PCI Express eSATA card to my G5

Hi All,
Not clear if this will work...I have a late 2005 model Power Mac G5. I'd like to add this eSATA PCI Express card: http://www.worldofcables.com/store/viewItem.asp?idproduct=9232
So I can use this external drive with it's faster eSATA capability: http://www.macmall.com/p/Fantom-Drives-External-Hard-Drives/product~dpno~7819677 ~pdp.ffadahe?store=macmall&source=MWB23824
It's not clear to me if my mac can accommodate this card...does anyone have more insight than me?
Thanks in advance,

I am a long time Mac User but I must confess I am not really a "power user" I use my mac to edit my gigs and thats about it. I have acquired a 6TB G-Raid External SATA drive with tons of footage and I need to be able to interface my G5 PPC to it. I need to add a ESATA card to my rig so I can get to that footage. Please, Please, Please help! If anyone can suggest a card that will work I would be so very happy! I would be happier still if it was affordable!

X58 pro i7 pci express 2.0 issue with sata controller

hello
i installed rosewill rc-225 (marvell controller) pci express 2.0 x1 card. my crucial m4 ssd maxes out at 271MB/s
it is installed in the x16 slot. i tried gen 1 x1 slot i was getting pathetic 130MB/s what is going... on new egg people with this drive and the controller are getting more than 400MB/s
btw i overclocked pci express and it improved the speed i dont get it what is going on...

Quote from: brasstech on 12-September-11, 09:33:56
Running Windows 7 Ultimate 64Bit, Video card is EVGA GTX295, Marvell 91xx Sata 6G Controller Driver is 1.0.0.1034.
Oh wow that is crazy.
So there are only 2 explanations left since I only have GTX260.
1. I have some fluke Rev 0 motherboard.
2. Marvell chip doesn't like Crucial SSDs. Which I did hear kind of on Crucial forum. (I am thinking this).
To finally conclude it is Crucial SSD, can you take me which revision/model of motherboard you have? I think i seen it on a corner of the motherboard printed. Or in the bios.
I'll get mine from the BIOS tonight.
Also I wonder if overclocking the CPU increase the speed.... I asked brasstech if he overclocked... I hope he did, that would explain things.

Desktop is not defaulting to PCI Express video card

Installed a Nvidia GTX 560TI w/appropriate power supply AFTER disabling secure boot and enabling legacy support. The computer booted to the video card after the second try reboot, drivers successfully installed. Later after attempting to wake the computer from sleep it has defaulted back to the onboard video WITHOUT restarting. Now will not recognize PCI express card.

Hi,
What power supply are your using? The stardard HP 460 watt power supply is insufficient for the NVIDIA 560 TI as it requires two 6 pin PCI-E power connectors.
Go back into the BIOS and make sure that Legacy mode is enabled and Secure boot is disabled. Save the changes and power off. Now power up and see if the system recognizes the discrete video card.
BTW - the PC needs to completely power down and back up before the BIOS will rescan for hardware changes.
