Guys please help, my asrock h81 pro btc arrived and i set it up with pci usb extenders and 6 750 ti , but windows is showing me only 5 cards , i cheked everything , changed slots , but nothing , the best i can get are 5 cards. Is there a driver issue or something else , i have a a friend who has the same board and puts 6 amd cards with no problem. Huh

?

I hope you get this sorted soon, i am looking at getting that board with the usb extenders soon

right now i am feeling the hate for getting a expensive motherboard as my has

2 x PCI Express 3.0 x16 slots (PCIE2/PCIE4: single at x16 (PCIE2) / x8 (PCIE4) or dual at x8/x8 mode)
1 x PCI Express 2.0 x16 slot (PCIE5: x4 mode)
2 x PCI Express 2.0 x1 slots

if only it was 3 @ x1
as you cant run the x1 risers in the x16 slots i believe?
and i know they don't make x16 usb risers

On a side not, has any tested what difference using longer usb cables poses?
For example mos are sold with 1m cables, but what is stopping you using 5m cables?

please someone test this xD

Yes i sorted it out , i disabled the onboard video and it turned out that one of the extenders was not very well , and now I am a proud 6 x 750 ti rig owner. But i can tell that for good results , you should be using at least 8gb ram , i couldnt get them runnig with my previos settings , wanted more ram.

Interesting, where did you turn off onboard video? I'm running an i3 in mine and couldn't find a simple setting in the bios like my Gigabyte board has.

I also noticed the ram thing but thought it was a page file issue since I was using 18 of the 20gb drive i had in there previously. I currently have a larger drive and 4gb ram in there. I'll have to try 8gb now and see if that is stable.

FYI, it seems I was only able to detect 6 cards when I updated to service pack 1, so if you haven't yet, you'll need to make sure it's all updated.

I have to find a 5 m cable first... and i will write back

As for disabling the onboard video , you go into the bios and set vga device to pci-e and a little lower there is an multimonitor option - disable it and you a good to go.
I am having other issue now , the cpu runs 50% with -H 2 and i can`t understand why? Task manager says cudaminer is using it.
