So i recently changed motherboard from a mini itx H67 motherboard to a full blown asrock z77 extreme 4, Everything seemed fine untill i checked the PCI-Ex16 slot and found that the PCI clip was broken off (seemed like a minor issue since my last MB had the same issue x3) regardless now that everything is installed i am getting much lower fps and am noticing SIGNIFICANT stuttering. I've tried changing to the 2nd slot and that gave me even lower fps on avg.
On skyrim i see 60-30fps and on games like battlefield i see 45fps average, no matter what settings.
someone send help and doritos :"(
Specs:
I5 3570k
Gigabyte Mini ITX GTX 970
8gb Corsair Vengeance Ram (2x4)
120gb Kingston SSD
3TB 7200 Seagate HDD
Hyper 212 Dual fan
500w Fractal Design PSU

As i said even if i put everything to ultra it does not increase or decrease FPS i also reset my bios and i am in the midst of reinstalling my mobo drivers :(

Did you just switch boards and not reinstall windows ? It sounds more like the GPU is sharing an interrupt with something else; which might happen if you just switched boards and windows happened to decide to share it with something that also has a high priority. In this case, uninstalling your GPU drivers and rebooting with onboard graphics, then shut down and reinstall the card on a different slot and redo drivers may help. It usually causes windows to recheck and reconfigure the hardware.

If that and clearing the CMOS doesen't help, maybe a pin in the slot is damaged.

I have two x16 slots (8x/8x for sli use) and both slots have the same issue, is it possible for both slots to be broken ?

Yeah, I was thinking it might be a driver mess, but I've switched lots without reinstall and never had it slow down. Just re detecting stuff took all day. This was only 7 and up, cause XP would bsod. AFAIK those old drivers are ignored and not loaded, but I am no programmer or anything, just a long time user.

Since you reinstalled it shouldn't have put your GPU on a shared IRQ but it's possible. According to Nvidia, it should have it's own if possible because they don't share well. Even if it get's stuck having to share, it shouldn't be sharing with something like your sound for instance, or mouse IRQ.

I hope you get it sorted.

Hey! thanks for all the help so far! i have (after some fiddling) removed my gpu,booted onto my igpu, removed all my graphics drivers and i am now doing a windows "reset" since i do not have a windows 8.1 usb drive on me right now .

Nonetheless i feel that it must be software related since it's very improbable for BOTH pcix16 slots to break on a brand new board.
