Xeon E3-1245 v5 Windows 7

[Zuzek__Peter]

Hi,

We are trying to use the Intel OpenCL compute capabilities of the HD P530 GPU on the Xeon E3-1245 v5.
Although we were successful in getting the P530 to work under CentOS 7.2 (using the patched Intel kernel 4.4), the same machine running Windows 7 (in dual boot) does not show the GPU while running clinfo, nor does manually querying for the GPU using clGetDeviceIDs return a valid GPU device. 
Windows 7 is fully updated, the version of the GPU driver is 15.40.25.4463, the motherboard is Supermicro X11SSD-F, the GPU is enabled in the BIOS, recognized in Windows 7 Device Manager and, again, fully operational on the same machine running CentOS.

Is there something else that needs to be enabled to get the P530 to work in Windows 7?

Thank you and best regards.

Hi Peter,

There are no additional requirements from an OpenCL perspective.  Thanks for adding the background on what you tried with CentOS.  This shows that BIOS, chipset, and related concerns are ready to go. 

The first place to look is probably the graphics driver install.  The processor you've listed isn't officially supported by this driver.  This isn't an automatic showstopper but it may help to look deeper to ensure that the driver install was completely successful. 

• Does device manager show that the Intel display adapter is available, using the 4463 version of the driver?
• Do apps based on other graphics APIs work with GPU acceleration (DirectX, OpenGL, Media SDK?)

Thanks, Jeff

Hi Jeff,

thank you for responding. We are aware that the processor is not officially
supported by the current driver, but were under the impression it might have
been supported by an older driver - could that be the case? Is there a version
of the driver that does support this processor? We tried installing older
drivers, though, with no success. We were able to get the HD 530 GPU to work on
Windows in a different machine, so we thought the HD P530 wouldn't be much
different.

The Xeon E3-1245 v5 was meant to be used as a compute-only node and is not
attached to VGA, so it cannot be used for OpenGL or similar GPU accelerated
tasks. The Device Manager does show the HD P530 as a Display adapter, listing
the correct driver version.

Thank you.
