Just curious what prevents S1070 to work with Windows – it should just appear as 4 PCI-E devices, right??
Is it a problem with WIndows PCI-E enumeration that is NOT seeing the devices attached via the PCI-E extendor cables?
Is the host-adapter designed for use in host system NOT working properly with Windows?
I also can confirm that S1070 works with XP64. I’ve tried 181.20 and 185.20 (from laptopvideo2go.com), both seems to work okay. The only ‘hack’ in my case was to extend windows desktop onto all C1060, without this they are visible in Device Manager but CUDA reports no devices.
