Want to make 0.01 btc? All good advice on mining rig wil get it.

[KoningSilk]

I've been trying to setup my mining rig. I've come close to getting it work, but sadly im not yet there. Everyone that gives a solid advice which gets me closer to my goal, will receive 0.01 btc if I get my rig working.

This is what im working with:
asrock h81 btc
6 times radeon 270
windows 7
vengeance 8 gig ddr3 memory
2x 650 seasonic

So far I managed to get it working with 2 graphic cards plugged in. However, if I plug in a third graphic card, it doesnt want to turn on. Sometimes though, everything works (led, fans on motherboard, fans on graphic cards), but I don't get an image on my screen. (working screen, tried different graphic cards to plug in the hdmi connection). Anyone got a clue about what it could be?

I grounded both my PSU's together with a piece of steel.

This is about a mining hardware problem, not a cryptocurrency question. Thx anyway.

This forum is for bitcoin hardware IE ASICs and FPGAs. Alt-coin hardware questions should be posted in the alt-coin mining sub forums where they belong. You'll actually find answers there since GPU miners post there.

Edit: See? Your post is now where it belongs. Magic.

Have you tried presence pin shorts in the GPU slots?

When you manage to get to windows with all 6 cards plugged in, how many cards do you see in the device manager?

Also, try adding one card at a time.

Use BAMT or upgrade to Windows 8.1.  I had issues with Windows 7 getting 5 cards to run.  Windows would recognize all 5 cards but one would have an error 43 and would not install the driver correctly.  Once I installed 8.1 it had 0 issues.  BAMT is also a good choice but you cant underclock the cards.  How do you have the PSU set up on the cards?  I would run 1 PSU with the 2 main cards and then another PSU with your remaining cards.  Might be a power problem.  Try 1 PSU with 2 cards then add 1 more card on 2nd psu at a time.
