I have to ask this question again.
My motherboard is Intel S5520SC. I disabled its integrated graphics card.
I installed GeForce 9500 and tesla C1060.
using nvidia-settings, it shows
GeForce 9500 works on PCI Express 16X
But Tesla 1060 works on PCI Express 8X
Someone reminds me to double check the motherboard to make sure all 16 lanes are electronically connected. I’m sure on that. I also change the GeForce 9500 to the slot where C1060 was on, it also works fine.
I also did some search, someone said it does not matter. Then my question is why my C1060 has to behave differently from what she was supposed to? Also is it really equivalent for working on 16X and 8X?
Thank you. It explained something. I’m checking the specification of the motherboard (hard for me). Does the distribution of PCI lanes depend on hardware address? I mean if I exchange the location of the two gpu cards, will the number of lanes for each exchange also?
About the second point, I don’t know how to test the bandwidth of C1060? How did you get the value 1~2GB/s? Isn’t this value the same for all Tesla C1060?
