HI Omi
I am hoping you can help me
I have searched for hrs and cannot resolve this problem. I have the P8Z68-vPro/Gen3 board with the 1101 flash.
I am running 2 GTX 560 TI direct II cards and basically as soon as I install the nvida drivers the machine just reboots in a loop ..
If I take the drivers off it will boot into Wins 7 (pro).
I have tried updating bios, gone down to one card, and i am set to pcie/
I cannot understand what is wrong.
I hope you can help
thanks
Hi,
You don't mention the other system specs with which to make a better assessment of your issue.
I'm assuming you have [strike]a Z68 board.[/strike] A few ideas come to mind.
Mainly this sounds like a bus contention issue with the cards. Here are a few suggestions.
- Turn "off" any internal video in the bios with any SLI/Xfire setup.
- Set bios to PCI-E as the primary video bus selected.
- Start from scratch again after removing all video drivers (nVidia, Virtu) and only a single card in place at PCI-E 1.
- Start with one video card. Boot to this card without any drivers loaded (Generic MS driver at base 640x480x60)
- Add the video drivers at this point. Set the resolution to the base resolution.
- Boot to this configuration at least 2 times to ensure the changes made have been seen/preserved by the opsys properly.
** if that appears normal then proceed to add the OEM (not nvidia) video drivers.
- If this is normal, then proceed to install the second card in PCI-E 2 (No A/C power connected) and proceed with the SLI setup as outlined in your MB manual.
That usually solves most issues like this (barring any true hardware flaws in the devices themselves).
Note:
You also may want to test each card individually first. That is to say.. use each card in a single card configuration only. Use this to verify they each operate as expected and have no descreet hardware issues apparent on either device.
Addendum - I meant to say a good Power Supply, not Z68 board .. Busy day.
2x 560Ti will need at least an 800 Watt (Silver 80 SLI or better). Toward 1000 watt if you have many HDD's and multi monitors.
**Sorry for the mistype... my mind can get way ahead of me sometimes.
