Motherboard is broken ? GPU detected as DDR3

[ShadowTrolll]

Hi, i bought a new grapics card about month or two ago, its RX 560 2GB. From the beggining of me using it, i thought that games should run faster cuz it was supposed to be slightly better than my friend has. His games run 60 FPS high graphics, but when i play the same game i can barely sustain 60 FPS on low details. I already tried to do something with this problem but it didnt help so i gave up thinking the card is just weaker. But recently, i noticed something in SiSandra scan. The card is detected as DDR3 but its supposed to be GDDR5 and it runs only PCI-E 2.0 x8 while supposed to run on PCI-E 3.0 16x (already knew that but someone told me it doesnt make much difference, but i think it does). So i thought it could be because of the motherboard. Am i right ? Do i need to get new motherboard ? Or should i just take the computer to service and ask them to fix this ? Thanks for help

Whats the rest of your system ?? Cpu, board, ram etc.

Gpu spec looks fine , thats an error on scisoft sandra.
The amd driver clearly shows gddr5.

For full specs on gpu use gpu-z

For full specs on cpu, board, ram (you can switch tabs for each one) use cpu-z

It shows PCI-E 2 x8 but my screenshot program breaks it so it shows 1.1, but the render test puts it back to 2

Your board only has pci express 2.

Hence the readings in gpu-z

Further complicated by the fact that the rx 560 is only a 8 lane card,half the traces on the connector are not connected to anything.

What you're seeing in gpu-z is absolutely normal.

Pci-express 2 x8 will not hold back rx 560 performance in any noticeable way.

You have the fully shader enabled version of the 560 (the most powerful one) so if your friend has the same card you shouldnt really be getting any worse performance.

Then why do i have much less FPS in the same game on the same settings ? Is it CPU ? Or the fact i have HDD ? Or is the GPU just, well, too weak ?

I dont know ,what setup is your friend running exactly ??
What game are we talking about?

Id expect the 560 to game fairly well at medium settings on most title's but maybe not at a locked 60fps.
Vice versa the i5 2400,itll still game ok but not at 60fps all the time.

He is away now but i am quite sure its quad core 3.4Ghz, R7 260x and 16gb ram, 1tb SSD. He goes full red.
We are playing R6 Siege

And what should i upgrade for the biggest performance spike ? I have money only for 1 good component so i want to choose wisely.
