What OS are you using for 7 cards startup?

Xubuntu 12.04

Jumpered all my x1 slots

UEFI Settings.... didn't touch any over clock stuff, disabled everything I'm not using (ethernet, sound, SATA, etc), disabled USB 3.0 as I assume my USB wifi was causing issues.

Can anyone verify that all 7 pcie slots work? I've been working on this for several days. I've got jumpers and the changed pcie settings in uefi. I still get nothing but problems when I install more than 4 GPUs. I'm runing Ubuntu 13.10, and it won't even boot half the time.
System browser in UEFI does recognize that I have a 5th card installed.

If someone has gotten this to work, please let us know exactly what you did: Jumpers, UEFI settings, OS and drivers.

I haven't been able to mine much, but help us out and I'll certainly send some coins your way!

I have 7 x R9 290x GPU's On this Mobo

-Use Windows 8 or 8.1
-Use LBR's modded drivers in the litecointalk forum, which allows windows to have more than 5 Cards, or else you will have 5 working and 2 with CODE 43 in Device Manager
-Make sure The 1st PCI-e Slot you have a 16x - 16x Extendor
-In Bios Make sure Link Speed on PCIE - 16x Are set to Gen 2, Gen 2, gen 2 I was previously told Gen 2, Gen 1 , Gen 1, But I realised Gen 2 Also Works. (I dont know what the difference is )
-MAKE SURE - you Short ALL the 1x Slots
-Make sure Your computer NEVER Sleeps, And Display Never switches Off In Windows Power Options

Thats what I did, And I used Powered risers on all slots, Not sure if that matters but I just did anyway

Interesting. While I don't have this setup I do have 5 - 7950's in a machine, Win8, 990FXA-UD5. Can you post a link to the modded drivers?

EDIT: Making sure windows display turns off doesn't seem to matter ,<<
Here is the link to the Litecoin thread and drivers

I have the same board. Use the "System Browser" under "Tools" in the UEFI setup at boot. You can see what slots have cards that are detected. I had to jump all my x1 slots as depicted above to use any cards in them. I used powered risers on the x1 slots.

You need to short ALL the 1 x Slots and then go to Bios and change the PCIE 16x to Gen2 , Gen 1, Gen 1

In that order and then you can plug anything into the PCie 16x slots.

I was told all 7 are good to go and very stable.

Hi, you can describe a connection order in detail? Not really I understand in English (
That means "need to short ALL the 1 x Slots" what exactly it is necessary to make, put crossing points on all PCI-E 1x? So?

win 7 4 gpu max ( able to do 5 on 12.6 ccc and 2.7 sdk, but if you got r9 280x your win will see r7990 with lower hashrate -550k/hash)
win 8 5 gpu max
All pcie enabled ? look on bios, try change the pcie slots, powered risers checked ?
what drivers ,sdk you got ??

I was able to get 5 to show in device manager but triangle on one. Novymivo care to share which order of slots are ideal for 4-5 gpus?

Just to update on this, the day after my initial post this board started smoking and took out the cpu with it. Luckily all the gpus and psu survived. I returned it to the shop and got a refund.

What video cards? Any with Dual GPUs? I believe windows has a limit of 8 GPU Cores and once you pass 3 they seem to be fickle about the Catalyst, SDK, and mining software versions.....

Hey i know its been a day but did you ever get the 5th card and get it in the board. I was looking at getting one of these boards for my next machine as i want to run 5 cards maybe 6 with two psu's if windows will allow it.

I have a 1150w aerocool & an antec 650w both gold...trying to get 3 gpu's from the aerocool & 2 from the antec, have managed to get 4 into windows now after updating bios...I think I may get there, albeit slowly.
