I ran bandwidthTest with very low memcopy results:
Host to Device: 160MB/s
Device to Host: 200MB/s
Device to Device: 65GB/s (is ok)
The Tesla C870 Card is plugged in the pci express x16 slot in the mainboard ASUS P5B.
In another PCI slot a GeForce FX 5200 is installed. I hope thats not a problem…
Any ideas to solve this problem? Maybe any special Drivers/Settings in BIOS or WinXP necessary?
Can you advise some tools to check if the mainboard pci express bus works correctly?
EDIT: I’ve looked in the NVIDIA Control Panel -> Help -> System Info for Tesla C870. In Details of Tesla is Bus only set to PCI Express x1 instead of x16… I’ve checked the mainboards User Guide, google and so on… What is wrong???
Thanks for help!!!
