I’m in the process of setting up a Tesla S1070 connected to a server running Windows 2008R2 64-bit. The Tesla driver installs nicely, but in the device manager one of the four Tesla CPUs is marked as not being installed correctly. Upon further inspection the reason is “This device cannot find enough free resources that it can use. (Code 12)”
Has anyone else experienced this problem?
The server is an HP Proliant DL380 G5 with 2 quad core Xeons, 16GB RAM, 2 GigE NICs and a HP P400 RAID controller. The RAID controller is attached to one of three PCIe 8x slots, while the Tesla boards are connected to two PCIe 16X slots on a riser card. (It is not possible to move the RAID controller to any of the other slots due to the bulk of its connectors). BIOS, RAID-controller and NICs are updated with the latest firmware. The Tesla driver version is 196.28
There’s a MS KB article on resource problems with PCIe riser cages, http://support.microsoft.com/kb/942959/, but it doesn’t say if it applies to 2008R2 or not. I’ve tried the workaround from the KB, but the described registry setting seems to have no effect.
I’ve also tried disabling as many devices as I can to free up IRQs etc, to no awail. Any other ideas?
