Issue with devices working together

hintermirischeinwand · June 24, 2015

Hello,

I tried to install my old Intel NIC and sadly ran into some issues I can't really solve. I'm not actually a noob in PC stuff, I even work in the IT, but this Problem drives me crazy... Tried a lot but can't imagine what's the Problem and thus don't know how to fix it, so I hope someone can help me out with this.

My PC specs:

Mainboard:

X87 XPOWER from MSI

PSU:

HX1000 from Corsair

1x 20+4-Pin ATX
2x 4+4-Pin ATX12V / EPS12V
6x 6+2-Pin PCIe

GPU:

GTX780 Ti

Audio:

Essence STX II

NIC:

Intel CT-Desktop Adapter

I had everything running for months (without the NIC) and I wanted to install my old Intel NIC. So I installed it into the x16 PCIe Slot and booted the PC. I tried to install the Drivers, but it told me that there was no Intel NIC found in my System. Then I shut down my PC again and swapped the Audio Card and the NIC from the x16 to x1 Slot. After I booted up the PC again, the NIC was working and I installed the Drivers, but I noticed my Audio Card was not working anymore.

To make things short:

I played around with the PCIe Slots. Swapped the GPU/Audio/NIC around and it never worked properly. The only way the NIC and Audio Card work together was when i put the GPU into the 1st PCIe Slot (which according to MSI is not recommended. They recommend Slot 2 for single GPU). But the Problem is, that the GPU will only run as x8. In the 2nd Slot the GPU runs at x16, but then only 1 additional Card will work -> Audio or NIC, but not both

I checked the Mainboard instructions and read that there is an additional 6 pin ATX power connector for the PCIe Slots. But my PSU does not have another ATX cable. I tried a PCI-E cable instead that had 6 Pins, but I am not sure if that works, at least it didn't fix the Problem -> so maybe no power Problem?

Does anyone know what's the Problem and knows how to fix it?
