That board is worth its weight in gold! Super easy setup and configuration - 6 cards, ultra stable! Highly recommend Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: atp1916 on January 29, 2014, 03:34:53 PM Just ordered me 2 of these boards for another set of x6 270 rigs. Very awesome to see such results.
However, the one thing you did not mention (or perhaps i missed) was the exact driver revision you guys used in Win8.1. I would assume latest Betas or 13.12s, but would like confirmation.

Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: Ritual on January 31, 2014, 08:20:48 AM Bittydude, wrt to running on one PSU - you can, if you can find one large enough. That's the tricky bit :)
Anything over about 1500W is very hard to find. Not to mention seriously expensive. Rit. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: RickJamesBTC on January 31, 2014, 08:22:11 AM Well I couldn't get any of my 270 non-x cards stable with those settings, but I did work them up to 470kh each with i 19, engine 1100 and memclock 1450
Rigs were crashing if I tried anything higher, intensity or the clock settings.... That's with powercolor r9-270 cards, I'm happy enough with them to use them instead of paying more for 270x cards if they stay stable long term at 470. They use much less power and only have one pci-e power connector to deal with wiring up. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: Dabs on February 01, 2014, 02:53:58 AM Mine are Sapphire 270 (not X). I may have to slow down my settings a bit to make it more stable, but it looks stable to me, having run it like that for the past 2 to 3 days.
Also, I'm on Litecoin BAMT 1.3, not Windows. A local supplier says he got a few of those motherboards on order, so I reserved two. Let's see if they get it. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: RickJamesBTC on February 01, 2014, 02:58:41 AM I'm not using windows either. I still can't get these cards to be stable at such high settings. They get sick or crash every few hours. Back down to 430 a card for now until I find a better way. I have a bunch of these pro btc boards on the way, retail prices, I hope they work fine with 6 cards each.
Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: kcobra on February 01, 2014, 07:59:46 AM What's the consensus on whether powered risers are needed or not with the H81 Pro BTC motherboard? Seen a lot of posts saying they are not needed while I've seen other posts still saying they are needed.
Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: Wipeout2097 on February 01, 2014, 10:16:53 AM This video is excellent, except his rant regarding the MB being Intel based and fanboys and all that.
The core issue is coin mining, not marketing, fanboyism or other drama. What matters is performance/cost and if the hardware works. One uses components that suck less and get less in the way of mining. Intel based allows one to use a Intel CPU with integrated video which stays completely out of the way of mining and the videocard that is plugged on the PCI-e 16x slot. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: coincowboy on February 08, 2014, 01:10:38 AM I am seeing ATI driver crashes with a single 7990 on this board. If I even put a moderate amount of load, it crashes. Anyone else seeing this? I'm wondering if its the board or something else? This is driving me a little crazy.

Seen a lot of posts saying they are not needed while I've seen other posts still saying they are needed. People keep asking this, but the main thing to consider is that with the usb risers you can put the gpu cards far away from the motherboard, which allows for much better use of space and cooling options.

If so, could I ask you to check your PMs please? I need to buy some and had sent you a message for details, as requested in your thread. Hoping for a reply soon :)
Rit. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: coincowboy on February 08, 2014, 05:41:23 PM I have some non-powered 16x to 16x risers if you are interested. PM me.
Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: Ritual on February 08, 2014, 05:44:52 PM 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! Rit. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: RickJamesBTC on February 08, 2014, 06:56:00 PM I'm always selling them! I just shipped the last ones of last week though. Taking orders for the next shipments now.
Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: Ritual on February 08, 2014, 08:26:38 PM Hiya Rick,
Thanks for your PM. Looking forward to ordering ASAP! Rit. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: searrching on February 09, 2014, 05:28:19 AM http://youtu.be/t3iup26oUN4 (http://youtu.be/t3iup26oUN4) 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 Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: K01N on February 24, 2014, 01:42:18 AM 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. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: K01N on February 24, 2014, 01:53:23 AM 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. Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: RickJamesBTC on February 24, 2014, 02:18:57 AM I've got zero problems booting headless on pro btc boards with xubuntu. Six cards on risers, no dummy plugs, no monitors.

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? Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: RickJamesBTC on February 24, 2014, 09:03:39 AM 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.

Title: Re: BBT Episode 7: 6 GPU Mining Rig with ASRock H81 PRO BTC Post by: Antspaar on June 13, 2017, 01:20:49 AM 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!!

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. |
