DRIVER_IRQ_NOT_LESS_OR_EQUAL (igdkmd64.sys) Blue screen of death potential resolution.

I have been recieving the above error in a BSOD at various points in both Rocksmith and Rocksmith 2014 on my Lenovo Y510p. The desktop with intigrated radion worked properly so I just thought it was a windows 8.1 issue. But it appears that is not the case.

igdkmd54.sys points to the Intel HD 4600 graphics card built into the chipset on the lenovo y510p for gaming and other High demand applications the Nvidia Optimus software is supposed to switch the graphics to the Geforce 755m chipset. Apparenlty in rocksmith this does not happen and it triggers an IRQ Fault when the Intel Driver flakes out.

Here is the solution that I got to work so far. The default global settings are Intigrated Graphics and well the Intel HD 4600 while not terrible is not the 755m
Open the Nvidia control panel
Click on Manage 3D settings
Click on the Global Settings tab
under preferred graphics processor select High Performance Nvidia processor.
Click apply

Click on the Program Settings Tab
Click the Add button under select a program to customize Select Rocksmith 2014 and under preferred graphics processor select High Performance Nvidia processor.
Click apply

Repeat for Rocksmith if you
Use the default settings ingame as when I turn it up to 1080p the application crashes but the computer does not bluescreen.

I was able to play for 3 hours with out any issues if anything changes I will figure out the solution and update this thread.

That's not quite what that means. IRQ = Interupt ReQuest. These are normal, and happen all the time. A peice of hardware (or it's driver) asserts an IRQ when it needs the CPU's attention. If it's got a higher IRQ level then whatever is currently going on, it gets attention immediately. Otherwise, it has to wait it's turn.

That STOP basically means that the driver in question is trying to talk out of turn. Since the OS now has no idea if memory has become corrupted or not, it BSOD's and forces a reboot.

It's almost definitely something wrong with the Intel graphics driver (or possibly a hardware problem.) The NVIDIA optimus stuff only applies if you actually have a laptop with that kind of hardware in it. Otherwise, the probable solution will be to visit Intel's site and get an updated Graphics Driver .

what you can do is change your "assign IRQ to PCI devices" option in your bios , sometimes it causes issues , especially with windows since it's a plug and play OS.

you should be able to see all of your assigned IRQ's in your device manager - view - by type

although honestly it's really not that common anymore , back in the old days of win95 it was common to have irq issues , i know i have had to manually assign IRQ's to several devices to make them cooperate with eachother.

Thanks for the comments, I changed the above fix to reflect the fault vs interrupt. I used the wrong term.

So If you know of anyone else witha laptop running Nvidia Optimus feel free to direct them to this potential fix. It worked on one computer perhaps it will fix others.

DoTA has this particular problem as well.
