Did you reboot after running the force enable ?

Thanks for the quick replies. Yes I rebooted after running the patch. The patch looks like it runs as I can see the edit line afterward. Nvidia control panel shows 2.0 as well. So does Nvidia inspector. I'm using GPU Z 8.0.

Thanks Sajin My bios is not the most recent but is updated to a version that does include support for pci-e 3.0. Gen 3 was working and reflected in GPU-Z until today when I installed the 970 using driver 344.48. Now it wont go to 3.0 with the patch or even the manual regedit for win7. I read through the thread you provided but don't see anything I haven't tried other than updating the bios to the newest version. I'd like to avoid that because my OC settings will be lost. Unless I'm missing something I shouldn't need the most recent bios since it was working this morning on my 670. Any other thoughts? Much appreciate the help!
 

Gen 3 is set in the bios for all 3 slots. The card is in slot 1. As I understand it a Sandybridge board with an i7 3820 needs the patch for 3.0 to work. I just don't get why it was working with my 670 and all I changed was the installing the 970. Computers...gotta love em!

Wait so you're saying the patch doesn't work with a 900 series card but does with older cards? Wow if that's true it's kinda surprising isn't it. Sure not changing a good cpu for pice 3.0. On a single card it probably makes minimal difference anyway.

Ask yourself this question..............
"What incentive does Nvidia have to continue to provide a workaround to an issue that Intel created by not following thru on PCI-E 3.x certification on SB-E CPU's when they debuted w/ X79 chipset (as Intel had said they would)?" Personally I don't see any......
 
It's your money to do as you wish but this is how I see it............................
 
1.) If you're planning to upgrade to DDR4 stuff then I wouldn't spend any more money on this platform....save it for the new one.
2.) If you're planning to hold on to your 2011 stuff then I would do the mobo BIOS upgrade & get an Ivy Bridge-E CPU (or just do the mobo BIOS upgrade) to end this issue so that you can have some peace of mind going forward. IMHO the TDP advantage of IB-E over SB-E is something to consider as well...................
 
I myself am planning to keep my 2011 platform for a LONG time thus I've already taken care of this. Ain't falling for the trap that I believe X99 is this time around.............
Somehow I believe that Intel will put out a limited run of DDR3 Haswell-E socket 2011 CPU's as a swan song gesture to entice upgrading to X99 & DDR4 before they finally kill 2011/X79 support...............
 
I may be naïve here but I'm gonna wait em out....................
 

 

The 3.0 enable patch worked ok on my p9x79 Pro with a 3960k processor and I am using EVGA GTX 980 SC SLI. I always right click the app and run as administrator and restart.

The SNAFU
Is the 3960 different than the 3820 in terms of pci e 3.0 support? If not then I don't see why adding a
970 has resulted in the inability for me to get PCI e 3.0 on my p9x79. I am led to believe the patch doesn't work for 900 series cards. But your case seems to suggest otherwise. Again it was running 3.0 with my 670.

No See  i7-3820 3930K 3960X and 3870X and look under PCI Express Revision on the chart.

Thanks everyone for the input. Seems to me I'm back where I started. I should be able to get 3.0 using the patch but for some reason no joy. It's more the fact that apparently it should work than it is a significant loss of performance that keeps me seeking a solution. Any ideas to try are welcome.

Any ideas to try are welcome.

Let's clean up your graphics driver, registry & windows startup programs then we can try to manually enable the patch. Let's start with cleaning up your graphics driver, registry & windows startup programs first...
 
#1 Create a system restore point. 
 
#2 Download & Install CCleaner & Driver Sweeper 3.2.0.
 
#3 Remove all NVIDIA software from add/remove programs.
 
#4 Reboot into safe mode with networking. This will allow you to access the net while inside safe mode.
 
#5 Uninstall Precision X/Afterburner if installed, make sure to select "no" to saving profiles when asked.

 #6  Run driver sweeper 3.2.0, check mark NVIDIA - Display & NVIDIA - PhysX, select Analyse button, if a list of entries pop up select the Clean button, when asked to reboot select Cancel. Do the scan again to make sure all entries are removed/deleted, if all entries cannot be removed/deleted please post that the entries cannot be removed/deleted along with a screenshot showing what cannot be deleted. If the entries were removed/deleted successfully continue onto the next step...
 
#7  Run ccleaner, select the registry tab, select scan for issues button, select fix selected issues button, when asked to backup the registry select "no" (we made a restore point earlier, we don't need to worry about backing up the registry entries.), select fix all selected issues button. Do the scan again to make sure all entries are removed/deleted.
NOTE: Two entries may still appear after multiple cleanings (it should be one or two and no more), this is normal and should be ignored, all other entries should be gone. 
 
#8 Delete NVIDIA GUID's using regedit. Click the start button and type regedit and hit enter. For windows 8 hit the windows key + r and type in regedit and hit enter. Navigate to...
- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Video (highlight the Video key and press the delete key.)
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video (highlight the Video key and press the delete key.)
NOTE: When deleting the video key you will be prompted with an error saying "Error deleting key, Cannot delete Video: Error while deleting key." Just ignore the error and select OK, all keys within the Video key will be deleted except for ones that cannot be deleted.
 
#9 Perform a clean boot of windows. This will cleanup your windows startup programs.
- Instructions on how to perform a clean boot of windows can be found HERE.
 
#10 Reboot PC into normal windows mode.
 
#11 Perform a clean installation of video drivers.

1. Download & save 344.65 driver to your desktop. 
2. Double click on 344.65-desktop-win8-win7-winvista-64bit-english-whql.exe located on your desktop & run the extractor.
3. Select custom advanced install, under custom installation options uncheck all options but physx system software, if you are using audio over HDMI please select the HD Audio driver, if you have a 3D capable monitor and would like to use 3D at some point select the 3D Vision driver also, check mark perform clean install, then click next to install the driver, reboot when asked.
4. Re-install Precision X/Afterburner if you want.

 
 
 
Now that we have the graphics driver, registry & windows startup programs cleaned up let's try enabling the patch manually...
 
#1 Click the start button and type regedit and hit enter. For windows 8 hit the windows key + r and type in regedit and hit enter.
 
#2 Navigate to... HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Video.
 
#3 Identify the correct registry folders for each of graphics cards you have installed. There will be one associated folder for each card installed. To identify the correct folder for each card, you will need to review the names of each folder within the “HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Video” registry directory. The folder associated with a graphics card will have three or more subfolders (depending on how many PCI-E slots available on the motherboard). The values listed for each subfolder will be 0000, 0001, 0002, 0003, 0004, and Video. Review only the subfolders labeled as "0000". You will know you have selected the correct "0000" subfolder when you see a registry labeled “DriverDesc” with a value that matches the graphics card you have installed. Example, the value in my “DriverDesc” registry value reads “NVIDIA GeForce GTX TITAN”. 

#4 Right click on the folder labeled “0000”. Select “New”, then select “DWORD (32-bit) Value“, then enter “RMPcieLinkSpeed” for the name of the new key. 

#5 Right click the “RMPcieLinkSpeed” registry you just created, then select “Modify”, then enter “4” as the data value and verify that the “Hexadecimal” option is checked under “Base”, and then select “OK”. 

 
#6 Repeat steps 4 and 5 for each graphics card associated folder (named “0000”) 

#7 Once you have completed creating the RMPcieLinkSpeed registry for each card, close the Registry Editor window.

#8 Reboot PC.

#9 Run GPU-Z and verify that the “Graphics Bus interface” value shows PCI-E 3.0 for your card. 
 
#10 Report back with results.

What motherboard BIOS version are you currently running?

I don't even see a 1302 BIOS listed on the ASUS website. http://www.asus.com/us/Motherboards/P9X79/HelpDesk_Download/ the latest version is 4801, you should really update your BIOS.
 
To install driver 344.65 try installing the 344.65 overtop of your current driver following step #11 above. 
 
To locate which process on your computer is causing the high load do the following...
- Download process explorer and run it.
- Select view (top left), select columns, select process gpu, check mark gpu usage (this will create a column on the main screen called "GPU", you will be able to monitor what process is using your GPU the most when idle.)

The SNAFU
So I should just install 344.65 without deleting .48 and should do so checking clean install?

Yes. No problem. Happy to help out.
