I need some help correctly placing my PCIe cards into my Maximus VI Extreme motherboard for maximum performance. The cards i have are:
*nVidia GTX Titan (PCIe 3.0 x16) - Performance priority at the expense of any other card.
*nVidia GT210 (PCIe 2.0 x16) - This is only used for CUDA and PhysX so bandwidth/performance is not a big concern.
*Adaptec 6405 RAID (PCIe 2.0 x8) - Performance and bandwidth matters but GTX Titan takes complete priority.
*Auzentech X-FI HomeTheater (PCIe 1.1 x1) - Only x1 support so performance doesnt matter at all.
I currently have them configured like this:
1. PCIe 3.0/2.0_x16/x8_1 - Adaptec 6405
2. PCIe 3.0/2.0_x16_A2 - GTX Titan
3. PCIe 3.0/2.0_x8_3 - GT210
4. PCIe 3.0/2.0_x8_4 - X-Fi
In this configuration the BIOS refuses to POST with the GTX Titan. To see the BIOS I have to plug the monitor into the GT210. I have not yet booted into windows with the GT210 to confirm if the GTX Titan starts working there. The GTX Titan works fine in both BIOS and Windows if I remove the GT210. The manual only covers how to set the cards up for SLI and not for normal non-SLI multi PCIe card setups. Can someone suggest a slot configuration or BIOS setting that will solve my POST issue and maximise the GTX Titan performance please? I heard rumor that slot 1 native x8 may be faster than slot 2 x16 but I havnt been able to find any solid info.
Thanks.
