Hi guys and sorry for waking an old thread.

My concern is: Am I good with one 1200w platinum ATX for: Asrock H81 pro BTC, Intel pentinum G3258, 6x MSI RX 580 8GB, 8gb DDR3 ram and 120gb SSD?
or... Should I buy a seperate ATX something like 450w for PSU and 1200w for GPUs?
Also, are powered riser cables neccesary for Asrock H81 with these videocards? I've heard Asroch H81 doesn't need a powered ones.

Thank you guys!!

Yes, a 1200W Platinum is sufficient. You are looking at somewhere around 800W - 1000W depending if you dual mine and undervolt the cards. It's always best to run a single PSU that can handle the draw at around 80% of the rated power for best efficiency if it has enough VGA connectors to use up to two per strand max and preferably one. Using dual PSU's is a cost savings measure on larger rigs since single high output ATX PSU's are very expensive. The PCI-E v3.0 specification allows more power to be delivered though the PCI-E slot. Newer cards draw more power from the slot than older cards and the wires on unpowered ribbon risers are too thin to be used under constant load safely. I would go with 6-pin 1x PCI-E USB powered risers.

May have found a work around... Plugged a monitor in to a 290 HDMI port in order to boot. The moment I saw the ASROCK bios logo pop up, I unplugged the HDMI cable. RDC worked after that, and I've got all 6 290's working great at solid has rates (just under 900khs/ea). In the past if I've yanked the cable the card it was on would loose hash rate after and eventually go kaput. But pulling it before I'm in the BAMT OS seems to have worked.

The real question will be when I restart the rig again...will everything be happy? Doubting it but will report back later when I do. For now want to see if this rig stays stable at 5300+ kh/s headless.

I'm doing the same thing.. Really annoying that this is a MB specifically designed for mining, yet doesn't support headless operation on 290s.

Anyone also tried the BIOSTAR mining board?

Unless it's dirt cheap, I don't see any advantages with this board over most others.

Actually it is cheap and in stock.

That's the exact same board as the pro btc, isn't it. Also, not in stock.

It is in stock atleast here in Canada.

It looks very similar, but I didn't see the two 4 pin power ports.

Both on the USB slots, at least I think. I don't change that often but I usually plug into the 3.0 slots on everything else. These boards were very easy to setup for me, no issues at all. Fire them up first time with a single card mounted on the mobo for the linux install, get everything installed, turn it off and plug in 6 cards on risers. They all start perfectly.

I've got zero problems booting headless on pro btc boards with xubuntu. Six cards on risers, no dummy plugs, no monitors.

There goes the theory everyone has that the BTC boards' BIOS is what is preventing it from booting... I don't think BAMT would be the issue, right? (if only because I can boot headless on all my other rigs with BAMT just fine... just not the ones with BTC H81 mobos)

RickJamesBTC: are you also able to boot to USB 3.0 ports on the H81, or only the 2.0 ports?

I'm rocking 6x 290 Sapphire Tri-X on the H81 with BAMT, so far so good, 3 days now. Only frustration is that I can't get it to boot headless.

Anyone found a work around to this? I also can't get it to boot on the USB 3.0 slots, even though I'm using a very high quality ultra fast USB 3.0 stick.

From googling around, looks like I'm not the only one with the headless problem.

Conversely, some say they can boot to the USB 3.0 slots fine... but no-one seems to be able to boot headless.

Bueller? Thanks in advance! Happy to toss some Doge for anyone who has Much Solution.

That board is worth its weight in gold! Super easy setup and configuration - 6 cards, ultra stable! Highly recommend

Great video! In it you mentioned that one card wouldn't come up in Windows 8.1 (exclamation mark in device manager), but that you just uninstalled/reinstalled it and all came good...

I'm having the same issue with my sixth Sapphire R9 290 card in my H81 PRO BTC - except it doesn't come good after uninstalling / reinstalling. Any ideas?

BAMT does recognise all cards on the same machine and work ok, so seems to be a Windows thing...

Any help appreciated!

Cheers

Hi coincowboy,

I'm really sorry man, but it's 6 card rigs I'm looking at building, and I wouldn't feel good about non-powered risers with that kind of build.

Thanks tho, I appreciate your reply!
