by the way. The 2 7950s I currently have going arent screwed/fastened on to anything they are just sitting there plugged in vertically on the horizontal motherboard. Is it a bad idea not to have them fastened on?
Typically as long as your board is in a stable location(away from fur beasts and other gremlins that might knock it about) that'll be fine, otherwise it's easy enough to use a small strip of aluminum and some sheet metal screws to create a bracket for some stability(or pick up a free/cheap pc case and cut it up)
gotcha. anyone else have problems with risers? I find alot more crashing with risers/ no post or boot. Ive changed the pci x16 to gen 1 which helps but doesnt solve.

I have the z77 extreme6 also and am running 2x7970s. It run just fine, though one card runs quite hot (91 on factory clock) because the card sandwiched between the CPU and other GPU doesn't have a lot of space to breath on this board. You may need to underclock it to get to safe temps, though the 7950s probably won't generate quite as much heat.
thats what ive been doing with 2 cards so far. i get high temps on the first one too. My risers always seem to cause issues, but connecting the cards direct to the boards has been successful.

7950s and 7970s dont mix well when mining. 7970s need g=2 while 7950s need g=1. You can't set "g" to two different settings in any mining software. The cards will work together, but, to make hashrates normal on one card you'll have to sacrifice hashes on another.
should be ok with 2 cgminer instant

Just start two instances of cgminer.
One for the 7950 cards, one for the 7970 cards.
Select the cards you want to use in each instance with the -d parameter.

Gotcha. It's a 7790 actually

You probably won't blow the board. The main problem with boards is whether or not they have enough memory to support so many cards, but with only three you should be fine. Also, most people would agree that 3 cards is within the amount of cards where no added molex power is safe.
awesome! thanks for the help. This is my remaining board so thats why i am a bit iffy..... ill follow your advice.

Hello all,
I want to run 2 7950s and one 7790 on a z77 motherboard. Should i be worried about blowing the board? I can connect the extra molex for crossfire if that makes a difference.
Thanks!
