Hi everyone.
I'm running several rigs without problem using old parts (7950 and am3+ cheap mobo) without pb since 1.5 year.
I just ordered 6 new rig with boxes; as I plan to sold them later as computer.
I have :
mobo : ga-z77x-d3h Core : i7-3770 Ram : 16Go Sapphire 280x : X3 PSU : 1000w gold+
My problem is that only two cards are recognized by every OS i've tried, when the 3 are plugged in.
I tried with a powered X1 riser and the last card was showing up (in bamt), but not hashing, when temp was showing 511° (card was cold).
I have 6 mobo and 18 cards waiting in there boxes, and I really want to avoir riser cables.
Can it be one bad mobo ? I don't want to unpack if I have to change them; so only one is usually open (the one i'm testing obv)
If it's a mobo problem, which mobo can I take in exchange; if I want everything to work on the mobo pci-e slots.
When u read this I'm going to try underclocking every card to check if it's a PSU pb, but with three cards it shouldn't be a problem before mining starts.
I'm giving a 1ltc tip for the best answer (if it solves my problem.)
I'm so stressed as this investment is not only mine; so THANKS IN ADVANCE GUYS.
