I've definitely read some of the other stuff online about PLX issues with the board, but I haven't found anything to help resolve the issue on my setup. Most of the cases I have heard of online seem to have been ironed out. So far, I've had no luck. I already RMA'd the board once - I may have to try to get ASRock to replace the board with a different motherboard if they agree (again, they are currently insisting that they got a similar system to work and that I should check the GPUs and CPU in a different system...), just not looking forward to once again being out of a working system for a couple weeks while it gets sorted out.
BTW, I was running GTX 970's in SLI on the previous board in slots 1 and 5 no problem before I RMA'd it after getting the 980 Ti's because it no longer worked. I figured at the time that the PLX chip somehow died after installing the 980 Ti's, but like I said, the new board still doesn't work, though for completely different reasons (slot 5 on the first board wasn't even properly detecting the card at all times).
I am going to replace the motherboard as a last resort (either by asking ASRock to do it, or by simply buying a new one), however, ASRock is claiming they were able to get 2 980 Ti's to work in SLI just fine with the same motherboard and CPU (again, they were using EVGA SC+ 980 Ti's instead of reference like mine, which is why I decided to see if flashing my cards would fix the issue).
Still scratching my head as to what it could be....
just connect the os and the hdd to sata 1 ports which is near the mobo power connector , dont connect any thing else , better still if you can take out the mobo from the casing and place it out side to check.
1.check the molex connector that gives extra juice to the mobo is it properly seated .
2.did you flash to the latest bios ..if so did u choose default settings.
3.is the os a new one or being carry forwarded form a old build.
4.from what it seems the gpus are ok might be some thing going on with the mobo ...if my removing every sata hdd etc and just hooking the os and 1 hdd the problem does not go away do a fresh os install with clean drivers and check again .
if the problem comes back i would recommend u return the mobo and get 1 from asus or evga .
