    ASRock X79 Extreme4 PCIE-3.0 Stutter

    Whenever I run my card in PCI-E 3.0 mode I get random stutters/black screens/driver crashes, etc... usually 30min to an hour into gameplay, this doesn't happen with 2.0

    I've been doing some research and it looks like this isn't an issue specific to the X79 platform, as other users are having the same issue with different chipsets.

    My question is, does anyone here know about a "fix" for this issue? Other than using PCI-E 2.0; I'm aware that there isn't really "much" if any perf. diff between the two in the average video game. That said it's still an odd issue and I'm curious if anyone has found a solution...

    I am aware Intel released a microcode update around June this year that I've heard was intended to address an issue with the PCI-E bus signal timing issues, I'd like to know if ASRock has applied this update to the 2.10 bios or if they intend to add it to the next release as it seems to address the issue I'm experiencing... http://downloadcenter.intel.com/Deta...dType=Firmware

    Also, please don't blame this on the sandy bridge e microarchitecture for not being truly pci-e 3.0 compliant, as it's an issue that's also occuring with some ivy bridge users as well...and there's 3930K users out there running in pci-e 3.0 mode without this problem.

    Just to be clear I am not blaming ASRock for anything, I am just asking if it's something within their power to fix/address.

    NVIDIA released a new WHQL driver today, which might help:

      Hi parsec,
      I tried your suggestion and installed the latest drivers from NVIDIA *306.23*, however I am still having the issue with PCI-E 3.0, unfortunately it doesn't solve anything with that at all.

        Do you have the latest version of the Intel Management Engine (IME) installed? The version on your boards download page is not really new, and is the same one Intel supplies for their own X79 boards, so yours may be up to date, but just a thought. The IME is needed to get the PCIe 3.0 lanes working correctly.

        Intel has a newer version of the inf files installation program, 9.2.3.1023, which is newer than the one on your boards download page.

          Yeah, I've been running the latest ones from Intel's site, the only thing I've got from the ASRock download page is the USB 3.0 drivers, I'm still having the PCI-E 3.0 bug even with the latest Intel drivers from the Intel site.

            Bump

            Come on! surely someone from ASRock can comment on this, I'm willing to test any beta bios you could make to correct this issue etc, I just want to know whether you're willing to address this issue or if it's nothing you can address at all. Which would be unfortunate seeing as how some SB-E users don't have this particular issue which leads me to believe it can be addressed in a bios revision. However, if not I'd rather you let me know as that would be the fair and right thing to do as opposed to avoiding this topic alltogether.

              I would try contacting Asrock support. The chances of getting any kind of answer at all is better than on the forum, although they do surprise you sometimes. I've put in support tickets before with a phone number and they have called me, FWIW.

                Been there done that .. finally some guy emailed me and after a few correspondances he said he'd push it up the chain, but that was a long time ago now and I still haven't heard back on that. I'll keep pressing the issue with him, but hey, I figured that the "wheel that squeekes the most is the one that gets oiled" or however that saying goes, thus it couldn't hurt my chances to post my issue in here as well, since they've got this linked on their site for forums reg. discussuion of their products. Anyways... thanks for the suggestion

                  I don't blame you . I probably got lucky, but I had a pretty big thread on here for a while.

                    just run it in pci-e2 slot for the time being,you wont se any performance drop,only maybe a few fps in tri sli and super resolutions

                    as to what the cause is idk,what motherboard memory are you using and tested it for stability? could be bios bug or nvidia driver bug,i know they suffer from microstutter

                      Yeah, hopefully it won't be on for too long, like I've said I'm really just looking for either of two possible replies from ASRock, something like "no this isn't in our power to address, and this is why etc..." or "yes we can fix this, here's an eta etc..." whichever is fine I just would like an honest, concise answer...

                      My memory's listed in my specs, I've thrown prime, occt, ibt, hyper pi, memtest, and anything else I could think of at it, it is definitely stable. As I've said, the issue only happens when in PCI-E 3.0 mode, not in 2.0
                      I'm really leaning towards it being a signal timing issue, as I said earlier. I'm just curious if ASRock applied the latest microcode update yet. I'm running in PCI-E 2.0 for the time being like you said, I agree that the perf diff isn't really noticeable. I don't see the correlation between microstuttering and an issue experienced on the PCI-E controller resulting in the signal training going too quickly causing an unstable signal and signal timing...that's a cpu/mobo issue if you ask me, which is why Intel releases those updates for manufacturers to apply. On a side note, it'd be nice if those BIOS rev "release descriptions" gave a little more in-depth info than "update cpu code..." like what cpu code they updated, or if it was from intel, (the date of the release *if intel code update*)... It's possible ASRock's using the latest updates but I'd still be confused seeing how some users with different motherboards but the same cpu and gpu, don't have this issue in PCI-E 3.0 mode, as in true 3.0 as verified by bios desc, gpu-z, nvcontrol panel, etc, not overclocked 2.0 lanes.

                        Update 9/19/2012:

                        The PCI-E 3.0 issue is strictly related to NVIDIA kepler gpus, current gen3 amd gpus don't conflict with x79/sb-e. By flashing my GTX 670 to Palit's bios, I can now run my video card in Gen3 mode without any problems at all. This is definitely not an ASRock issue/problem. I've attached a copy of the GTX 670 bios that fixes the Gen3 stutters/crashes/blackouts for me. Just make sure and apply the X79/SB-E Gen3 patch found here: http://nvidia.custhelp.com/app/answe...QvaDEzbE45X2s=

                        Note: I'm using the PNY Geforce GTX 670
                        Driver version 306.23
