On the new H97 Anniversary ASRock Boards, if you have 3+ cards it wont boot unless you plug in the molex on the board. At least that was my experience, even with USB PCI-e risers.
I confirm that, I have a H97 Anniversary and mobo doesn't boot if you don't connect the molex on the board. I'm using it with 5 cards.
At the end my mobo is fried.
This morning I checked it because I couldn't connect via SSH ... and...
The problem is like roitpls said, if you don't connect the molex in the H97 Anniversary, the mobo don't startup...
Now I'm thinking buy a H81 Pro BTC, if the mobo let's the user connect the cards without connect the molex...
Well, now waiting for a new mobo
I run H81 mobos in all my rigs and have done it for years. I have never used the molex connectors because i have always used good quality powered USB risers.
Ok, I know it, and I readed a lot of information about not connect the molex to the mobo, ... but the problem with H97 Anniversary is that the mobo doesn't boot with +3 gpus if you don't connect the molex.. a message is displayed, and it's impossible boot.
Ok, then I will buy a H81 Pro btc. I expect the memory and cpu are ok!. 1st lesson!
Did you message say if you press the N button and it will boost and will never ask the same question again?
I don't remember if a pressed N, I don't think so. But I remember that the mobo couldn't boot, and I remember also that the screen doesn't show any messages about press any key to pass the check of molex.
I readed before about don't plug the molex connector, but as a said I couldn't boot the mobo. The rig was running about one month. Now, is too late to check if I can press the N key to pass the check.
To me it's really important to know if it's possible pass the check pressing N in that mobo, because I need to buy a new mobo and also in the future I think we couldn't find a H81 Pro BTC. Do you have a H97 Anniversary mobo without molex connected?
