EVO is normal 2.5" SSD, Gfx card is Asus gtx 1080 strix A "non ti". Yes 8pin is plugged as is every other cable, dont think system would even start if 8pin wouldnt be plugged in :)

All the relevant hardware is mentioned at the opening post. Top of those Fractal Define C case, 3x case fans and noctua D14 cpu cooler.

Ram kit is: CMK16GX4M2B3000C15

Well as non native english speaker i could of probably describe it better, didnt mean anything bad. But really case fans or cpu cooler shouldnt really have impact to PCI-E lane speeds.

Do you have ANY other PCIe cards plugged in besides the Gfx card ? If you do.. which PCIe slot is it in ?

No other cards/PCI-E devices plugged in. If i plug gfx card to the primary x16 slot (closest to cpu) it runs at x8 3.0 instead of x16, if i plug it to secodary x16 slot it runs only at x4 speed.

I have now tested it with 3 different gfx card which are all verified to work on other systems, and behaviour is same with all of those. Allready filled RMA form to the shop i bought the mobo & cpu as either of those is faulty.

Quick update. Send the parts back to the shop some days ago, today got email from them that parts are faulty and they send the replacement motherboard and cpu for me. They didnt describe was it mobo or cpu or even both, but it was hardware fault anyway.

I hope the new parts works, kind of sucks to buy new hardware via post just to find them faulty.

Thanks for letting us know and good call sending both the board and CPU back. It really could be either so better both than the wrong part Wink

Good luck with the replacements, let us know how it works out Thumbs Up
