GPU Upgrade not working. Need help

[ggny]

I was on these forum a few week ago asking for GPU upgrade help i bought one and it isnt working. My friend told me it is because it is for PCI Express 3 and my computer he think doesnt have that.

Its a XPS 8300 and i bought a Gigabyte r9 270. Does anyone with knowledge know if a XPS 8300 has PCI Express 3 or not?

PCI version largely doesn't matter. They're all compatible.

Is the PCI-E power (6 pin) plugged into the card?

Everything seemed to be plugged in properly

We couldnt get the monitor to display we tried a few different monitor and connecters. I dont know much about it but he seemed to think it was because of the card being PCI-E 3 and not 2.1

So the new GPU should work fine with my computer? Its either something wrong with the card or us?

PCIe 2.x and 3.x are totally cross-compatible. That is not a problem for you.

Should. Try pull out the card and re-insert it. Also try different PCIe slots if possible. The card slots arent best designed thing in the world, and sometimes it looks like you have the card bottomed out and connecting properly but it isnt.

if your motherboard has a onboard video card you may need to disable it or set the primary display to PCI-E.

PCI-E v3 doesnt matter , also check to ensure your power supply is getting enough power through the 12V+ rail if your GPU needs 35 and your only getting 20 you need a better power supply.

hope this helps you fiqure out the issue
