Not enough resources (code 12)

[Ivars_D_]

I am having problems getting my Xeon Phi 5110P to work on my current hardware.

Motherboard: Asus Z97-P

CPU: Intel Core i7 4790K

RAM: 8gb

OS: Windows 7 Enterprise 64x

According to motherboard manual, it has the "Above 4G decoding" option, which I enabled. Then I followed the setup guide and installed the newest drivers. When I go into Device Manager, I can see that my Xeon Phi is recognised but I get this error message: "This device cannot find enough free resources that it can use. (Code 12)". I found few other people having the same issue, but as far as I know no one managed to sort this problem.

From the Xeon Phi hardware requirements I tick all the boxes, but I am clearly missing something.

Any input would be much appreciated. Thank you.

In looking around on the Internet, I found a number of pages talking about this issue. In one case, it was because the connector wasn't complete seated, but in general, the problem was that another driver thought it was using some resource that the coprocessor actually needed.

In device-status-this-device-cannot-find-enough-free it says:

This error can occur if two devices that are installed on your computer have been assigned the same I/O ports, the same interrupt, or the same Direct Memory Access channel (either by the BIOS, the operating system, or both). This error message can also appear if the BIOS did not allocate enough resources to the device.

You have enabled 4 GB addressing, so it is unlikely the BIOS is not allocating enough resources. For all other causes, the advice seemed to be - find the driver that is using the resource needed by the coprocessor and remove it (in some places it said remove all the drivers - yikes!), remove the driver for the coprocessor, reboot and reinstall the coprocessor. Being a Linux person, myself, I'm not sure how much trouble you can get yourself into doing this but the solution will probably be somewhere along those lines. I would suggest you consult Microsoft or Asus documentation for the best solution.
