Has anyone had an issue with this board where after installing more than 2 GPUs the BIOS boot or the new Windows 8 splash screen won't load? With 2 GPUs everything works fine, however as soon as I add more no more BIOS boot!
Updated to the latest BIOS 1.30 but same issue. Is there a specific order of PCIe slots to install these into, currently only using the PCIe on non-powered risers.

I keep answering this, but this forum doesn't do a lot of searching 
Just use USB risers and the board is fine. It's got great bios, it's CHEAP and has six working slots. Preferably my risers, if you want.

Did you plug in double molex?
Yup, sure did

My opinion of this board- its a POS, gonna go w/ another board and powered risers, preferably USB powered risers

I sure did. I have 4 R9 290X running happy as clams with NON powered risers. All cables are cool and happy.
I would urge you to use the search function on the site and search on:
Asrock H81 powered risers
and see what you find, Youtube video not withstanding.

here is a youtube where you can see a guy installing the H81 PRO BTC http://www.youtube.com/watch?v=WfqfEpanpig
Hmmm he seems to say DO NOT USE POWERED RISERS.

I second the use of powered risers for any rig with 4 cards or more. Especially with 7970 or higher cards. They pull way more than 200 watts per card.
Always use powered risers if you are using more than 3 gpus ,if not than non powered is also fine.

These boards SPECIFICALLY have a power plug on the motherboard that you plug into that allows you to run unpowered risers.
Did you ask ASROCK? They made these board for mining.

Another question. I'm running a AX1200i and some of the power supply's PCIe cables have two PCIe adapters coming off one cable. My 270's have two PCIe plugs. Can I power that card with the one cable or do they need separate cables for each plug?
Stupid question...
Can I powered risers without plugging them into power? Will they operate just as unpowered risers would?

I am running 2 rigs with powered risers without plugging them into power without any problems. I have only 3 cards per rig though...

No make sure to plug them in. I wish we could as i would just use USB risers for everything.
A update was able to get ALL working. One card still runs slower then others 600ish isntead of 700ish. But much better then the 80 i was getting. Turned out i disabled and then enabled devices one by one it worked. So far 5+ hours up and running.
Will be splitting between two rigs tomorrow adding another card.
So motherboard can do 6 unpowered with a lot of messing around. Looking back 5 with powered usb risers might have been way to go. But I cant complain with them mining away dodge.

I really like the H81, i just wish i was able to get all non/powered. After multiple testing I was able to get 5 cards running good with non-powered risers. One card no matter what with non-powered one seems to run around 80khs (all cards are 280x's) so that is horrible. As soon as parts get here Monday splitting between two motherboards. Using two corsair RM 1000's as PSU's.

Is it better with powered riser?
Hoping to find that out soon when some hardware hopefully arrives (hopefully today). All my powered risers were in use and didn't want to take apart working rigs. My review so far is good motherboard, but a little over hyped from them. Looking back I should have just used all usb riser's and gotten the extra distance on risers.

Thanks! Have you encountered any issues when using powered risers with your h61 pro btc? Cause I have. https://bitcointalksearch.org/topic/lepa-psu-g1600-kills-powered-risers-454205
I did not attach the molex plugs onto the mobo, only onto the powered risers.

Yeah one of my mobos failed because I had a voltage issue. Idk what the real problem is maybe something to do with the rails and powered risers but I thnk from now on I am only gonna power 3 cards out of 6, and the 3 cards I power will be the ones I connect to the mobo.
