Okey, and as said previously i have amd drivers installed if thats a problem? Becuase i had a pc some time ago and i had this problem aswell. I fixed it with pluging in the old gpu and installed drivers for the new gpu and then it worked. But sadly i dont have my amd gpu anymore so i cant do that in this case.
-
The cpu im using is a brand new i7-7700k
-
If you mean that i should start the pc with no gpu in it and the monitor conected to the mobo. Ive already done that.
-
Emh, yes i think the pc starts normaly and sounds exactly the same as when i had the amd gpu's. But with no signal on the monitor
-
Yes, the monitor is connected to the gpu, ive tried connecting it to the mobo but no diffrence there.
-
Hi, iv'e just bought a new gtc 1070 but gets no signal on the monitor. Before this gpu i had amd rx 480 and had no problems, but now i cant get a signal. Can it be the drivers? I have the amd drivers installed currently. But its weird becuase i cant even get up the bios during start up. Ive also tried starting the pc without the gpu but it didnt made a diffrence.

Hi again , i have now tried with the corsair psu and the gpu usage changed a bit. Now the usage on the upper card is a bit more stable than before, now its between 65-100% almost all the time. But the seccond card is still jumping in usage from 0-100% The corsair was only 650w, do you think it will improve even more if i get a more powerful psu?
-
Will try the corsair psu then. How do i know if a psu have a good quality? What psu would you recommend IF the corsair does a better job than the evga one? Becuase i kinda need the corsair psu for another build.
-
Yea im not so much into overclocking, but do you think the problem can be the psu? Does the pc dont get enough power to run both cards but only one?
-
Okey, i have another psu witch is a corsair rm650x. Do you think that will do the job? And also, i havent tried furmark, but i ran the benchmark on heaven and i got the usage results i posted earlier from there.

im currently testing my pc on battlefield 1 with Dx11 with ultra settings and no AA, 1080pwhen im only using one GPU i get a stable usage on the gpu.(https://gyazo.com/2319bade693ae39294a013f8056435c0 (GPU2 is GPU1, its just displaying wrong name))but when im using two GPUs in crossfire i get this realy unstable usage(https://gyazo.com/e8af157cc1c176a475dd512b3e95e60e (same here, GPU2=GPU1 and vice versa)) The bad usage on crossfire is causing lower fps and fps dropps / unstable performance, in-game graphics flickering and worse overall performance than one card. does anyone know how i could fix this problem? I have tried both cards sepatately one by one and both have a stable usage. specs:gpu: ASUS Radeon RX 480 Dual OC 4GB (two of them)cpu: Intel Core i7-6700K 4,0Ghz ram: HyperX Fury Black DDR4 2x8GB 2400MHz mobo: msi Z170A krait gaming 3xssd: 240gb corsairpsu: EVGA SuperNOVA 750B1 750W

iv'e tested the GPUs separately and get a steady usage on both cards. but when i use crossfire the usage is jumping. here is the usage while in-game with only one card. (it says GPU2 but it displays wrong name, it's actually GPU1) https://gyazo.com/2319bade693ae39294a013f8056435c0 and here is the usage with crossfire (still, GPU2 is GPU1 and vice versa) https://gyazo.com/e8af157cc1c176a475dd512b3e95e60e and the usage issue on crossfire is causing fps drops, graphics flickering, and just worse performace overall.
-
Does it matter what test program i am using? Will i have the same ish results if im using furmark or lets say heaven benchmark?
-
okey will do that, just FYI the build is brand new, one 2 days old so i think both cards work propperly
