Hello guys!
So my problem is: Computer won't post(vga led is enabled) when GTX1070 is in Primary PCIE 3.0 X16(i've been waiting for 5 mins).
The computer pass post only if my GTX1070 is in PCIE 2.0 X4.
Currently RAM works pretty well 3000mhz dual channel, cpu ez overclocked to @4.0, but gtx1070 loss over 35% in fps while set in PCIE 2.0 X4.
PC posts only when gtx 1070 in secondary PCI slot(PCIE 2.0 x4)

I have bought:
1. New Ryzen 5 1600x
2. New Gigabyte b450 Aorus PRO
3. New 16gb Kit G.skill Aegis 3000mhz
4. New-used Inno3d GTX1070.
5. New Corsair RM750X - tested on many systems.

What I tried to do:
1.Go to bios -> set PCIE to use GEN3 and GEN2 - didn't help.
2.I've test my GTX1070 in MSI Z87(it has PCIE 3.0 x16) - and everything was fine.
3.I even bought second MSI b450 tomahawk but the issue was the same.(Vga led enabled, no post)
4.Update to latest BIOS.

So for now im sure:
1.RAM is fine
2.GTX1070 is fine
3.B450 motherboard is fine
4. But RYZEN 5 1600x i dont sure, maybe it has broken legs or something else?

What else could i try to solve the problem?





 
Solution
Ok so you've proven your graphics card works in another system. The next step i'd take is to run out to a local shop and purchase a different graphics card.
If the issue doesn't replicate with the other card, then that means there's some sort of compatibility issue with the graphics card and that particular motherboard.
Dependent upon the outcome, you can make use of the return policy for a full refund.

Could be a broken PCI-E slot or a broken pin on the CPU. I'd recommend taking out your CPU and making sure no pins are bent.

Yep i think so, coz i had 2 new b450 mobos, and noone of them work with my Ryzen 5 1600x

Well there's your problem, it's the CPU. Look for any bent pins, and give them and the socket a quick dust with compressed air just to be sure it isn't dust.

If it's just the one board, it could be a broken trace on the board, but they are quite hard to find.
