I'm in the process of building a 6 gpu rig. although now I'm considering sticking to 4, spend a bit more on more Mother boards, etc. but I'd like to run the 290 cards as well.
Suggestion on best mobo for these cards?
Thanks for the insight guys!

Win8 x64 supports 6 gpus but some driver tweaking might be required.
Here is a guide for it:

I pretty much wrote the steps for this a long time ago. This website is just adding pictures to my steps.
Also, this guide is invalid for any of the new R7/R9 GPUs (or radeon 7790), as they will not be supported with the 12.6 driver, which enables 6 GPU in win8.

Should really use linux with a rig like that. You spent that much dough on it but you are running Windows? Quite tragic... Linux is easier than people think. Your uptimes alone will be worth the switch.
i tried bamt, ubuntu, xubountu. i cant get pass boot. as soon as i click install the screen goes blank (black with underscore blinking).. apparently its something to do with my uefi bios or gpus or usb port or usb partitioning. will research later when i have more time. frustrated by now. ok gotta go to work now. hashing four cards right now at 825kh. thanks for all your help lads - will update this as i go along.

i tried this but the guide only has custom drivers for upto 7xxx models. i got new r9 290 video cards and totally stalled right now.
Windows 8 will do 5 gpu's out of the box no problem. Install different version driver than the other 5 for the 6th is also a trick I hear sometimes work. Then you got all 6 cards running.

I've had more than 4 cards working on Vista 64 bit so W7 should be no different
December 14, 2013, 12:53:54 PM
The !! ones in device manager is a driver/windows problem, unfortunately. You will be limited to 4 GPU in windows 7 (doesnt matter 32 or 64 bit), and probably 5 in Windows 8. Look up linux solutions to get all 6 working. I'm not fluent in linux, so unfortunately i can't help with that. Most linux guys here seem to keep to themselves as far as actually setting it up software-wise.

np np making progress now 
might need to install the drivers manually for the ones showing !! in device manager.
There's also another setting in the BIOS which can help, I can't for the life of me remember what it was........something to do with the pci-e lanes bandwidth. I know the setting was 96 or similar but can't remember the option. Something like "pci express lanes"
in all honesty I found windows with that amount of cards to be flakey, and went over to BAMT - apparently it does litecoin now too

It's been 3 years since I GPU mined but I think it had to do with the slot not recognizing when a card was plugged into it when using a riser

wow! thank you! i just shorted the presence detection pins and now i get all six cards in device manager, though two are with explanation marks! gotta work out what that means now. thank you Olly_K & ssateneth!

i had this board when BTC mining "back in the day"
I'm pretty sure I had to short 2 of the pins in the PCI-E slot. Even on the x1 slots.

could you elaborate please. i never done that before.

The motherboard should be fully capable of utilizing all 6 cards. The problem lies in using Windows, and driver support. Windows 7 will support 4 of these cards at the max. Windows 8 may support 5 (In my experience, Windows 8 would be able to operate 1 more card than Windows 7. This was with Radeon 7970's)
There are reports of being able to use all 6 cards with Linux.

you see it would make sence if i had all cards connected at the same time. but in my case i removed all cards and just attached master x16 card and second card through PCI_E1 - device manager shows one card only. then if i attach the same gpu with same riser to PCI_E2 slot then device manager shows two cards. in this particular moment its motherboard issue. i wonder if it has 2 faulty slots..

found this msi forum thread. some dude on reply #2 mentioned that 990 chipset only allows upto 4 gpus. in my case i just cant get PCI_E1 & PCI_E5 ports working even with only one master card connected - making 2 effective gpus connected to the motherboard. could somebody please confirm that.
https://forum-en.msi.com/index.php?topic=170785.msg1246971#msg1246971
here in the 990fx spec sheet we have mention of upto gpu 4 cards possible to be connected, though in crossfire. will they still be recognised without crossfire?

here is the little peek of how it looks like now. waiting for 3 140mm fans to go in front of those babies. there are three 750W corsair psus.

ok. little update. i had some time today to tinker with this project of mine.
i disconnected all but master card. checked all x1 risers - all working. then checked all pcie x1 ports on the motherboard one by one to see if device manager would see the cards. checked all cards - they all get recognised except when put in PCI_E1 and PCI_E5 ports. basically my motherboard dont see any card on those ports. ill google all i can but if you have any tips for me id really appreciate that. thank you.
btw im using 5 risers just like in the picture. i just cut the plastic limiter off to go into x16 cards:

What are you trying to mine?
anything that is profitable or easy to mine for the timebeing.
