Ok I give up. I need help
I have a
MSI-Z77A-GD65
Intel G1620
4GB Ram.
2 PSU's 1 powering the mb the other powering the cards (500w on the mb, 2000w server psu on the cards)
Sapphire r9 290x cards
I'm using usb power risers. I've tried win 7,8. I'm using all Sapphire r9 290x cards with the 13.12 drivers. I can't seem to get anything to run with more than 3 cards. I've tried every pcie slot combo possible. PCIe-Gen3 is set to auto in the bios and the pcie latency settings is set to 65 (also tried 32 and 128)
What am I missing? Why can't I get past 3 cards? Any ideas? This rig is pretty stable with 3 but I can't get it to boot with 4. ideally I'm shooting for 5.

You can set the PCEI to generation 1 or 2 if possible.
You may short the PCIE pin A1B17, the card presence pin.

Hiya Guys,
Has anyone tried out the new H81 asrock PRO BTC mobo?
I`m using 2x 6990 and 4x 5870 on it, and currently I got 2x 6990 mining with 3x 5870 by using a GPU card as the one which supplies the monitor.
If I`m using the onboard GPU (ivy bridge) to supply the monitor, I can only recognize 6x GPU cores.
Has anyone been able to get 8 cores running?
I`m using newest drivers as 11.12 isn't compatible with the 6990's.
I do NOT use powered risers since the H81 pro btc mobo has 2 Molex connections on the board for additional power to the PCI-e slots
For the rest I use the following
H81 Pro BTC
Celeron G1820
4GB Ram
Kingston SSD
Windows 7 64bit 13.12 drivers
Edit: 0.1BTC bounty for the one who solves this!

I'm using Asrock H81 pro with a 5870, 5970, and 3 x 280x. I can use the onboard GPU and still see all GPU cores: onboard GPU core + 6 pci GPU cores.
I'm using windows 8.1 and never have to load any drivers: just let windows decide what drivers to use. I highly recommend windows 8.1. You can get a CHEAP win 8.1 key on these boards for your rig.
cheapest 8gb ram for h81 pro btc?
how do I use onboard video for single use and gpu for mining? how do I set it up on sgminer or cgminer?
I don't think it really disables the GPU since Win8 still recognize ng GPU. Now, what might cause this issue?
I'm really close in buying new motherboard that supports 6

Maybe there is issue with the driver?
Check if any GPU has yellow "!" in the Device Manager.
The problem I have is that it appears that some slots are not active if another slot is in use.
When I plug a card into a slot and it's running fine, then I plug another card into another slot and the first card disappears.
Even though I have 6 slots on my mobo, I can't get more than 4 actually working at any time.

Other question:
If the card is blowing it's fan for 100% at startup and it's not recognized, is that a driver problem or a presence problem?
So if there would be a driver issue, it would be recognized in device manager but with an exclamation mark or something?
Cheers,

I think that's not a driver issue. 100% fan is triggered by card bios so it's alive but not seen by motherboard for some reason.
Can you seed all card's with flash tool from dos?
I have 6 cards per rig, 3 of them on powered risers... two rigs... 3 Seasonic 1250 Watt gold power supplies. Each power supply powers 4 cards.
I have the Gigabyte 990FXA-UD5 and the MSI 990FXA-GD80 and they both can handle 6 GPU's I believe (still waiting on 1x risers to arrive). It looked like they had been out for awhile so I didnt know if there was anything better on the market that most people were using or not.

Newbie question...
You have at least one PSU supplying PCIE 12V to 2 different rigs at the same time?
From my understanding, all the PSU's need to have GND tied together so that the 12V is not floating in a different spot between them. You wouldn't want to have a significant potential difference between any of the 12V legs or that could fry somthing (from my understanding).
I have spare PCIE power from a G1600, but didn't want to connect it to a second rig because I was worried about this.
Can you confirm how the 3 PSUs are shared on the 2 rigs? Thanks
I've read allmost the whole thread thru and would like to ask a question that has been asked around, so to speak.
Is it possible to use: MSI Z77A-G45 - Socket 1155 - Chipset Z77 - ATX
And all of it's 7 pci-e slots for mining with linux-distro (ubuntu or alike).
Thank you for your answers in advance.

I'll try to explain what I can since I can't make my 6 280x GPU to work with Asus P9X79 Pro motherboard.
I'm using 6x 280x + i7 3820 + P9X79PRO + Windows 8.1 Pro.
The problem lies between X16_2 and X16_3 (white slots).
When I plug risers on both X16_2 & X16_3... system can't detect gpu plugged in X16_2.
So, I shorted X16_2 and detects the gpu but the X16_3 seems to have a problem with GPU-Z sensors.
I don't think it really disables the GPU since Win8 still recognize ng GPU. Now, what might cause this issue?
I'm really close in buying new motherboard that supports 6

cant run even 5 cards on MSI MPOWER Z87 (280x cards)
only 4 are working
using BAMT 1.3
and 1x-16x power and non powered risers
g1820 cpu
do i have to shorten 32x slots to make them work?
board explorer shows that 2 x 32x slots are not present

I've just succesfully launched 4x7990 on Asrock FM2A88X Extreme6+, Win8
anyone uses 990FXA-GD65?
can anyone confirm it runs 6 gpu?

I can anyone give me advice on a nice 5 or 6 slot AM3 mobo? No mods requeird.
I got the ASRock 970FX EXTREME4 but its driving me crazy never get more than 3 cards working, got x1-x16 powerd risers.

Im having problems getting more than 4 cards to run on here this mobo. I bought it because i thought it would be smooth sailing with those 6 - 16x PCIe slots. How did you are you running more than 4 cards. Please crack an egg of knowledge over my head.

Hey guys,
I'm contemplating this board for my 5x 280x rig: http://www.newegg.ca/Product/Product.aspx?Item=N82E16813130727
MSI Z87-G55
Has anyone successfully gotten 5+ cards to run on this board yet? Perhaps 280x cards? If yes, what slots did you populate?
I ask because an older rig of mine runs on the Z77-GD65 and needed presence pins in ALL three 16x slots for six GPUs to run properly.
Thank you in advance
If you're only going to be using 5 GPUs, get the 970A-D3P. It's much cheaper than the one you linked, and I can confirm it runs 5x 280x or 5x 290 just fine. I'm contemplating this board for my 5x 280x rig: http://www.newegg.ca/Product/Product.aspx?Item=N82E16813130727

Did this board need presence pin shorts for any of the slots?
