I have following parts:
- 4x Sapphire Radeon 6990 - Gigabyte GA-990FXA-UD7 Motherboard - 2x Antec 1200 Watt PSU's coupled together - 4x 16x PCIe extender with power connected to the PSU directly. - Windows 7 64-bit - ATI 11.8 drivers
However, I can't get everything to work together. Up to 3 cards, everything works stable. When I add the 4th, the system almost always (99% of the time) doesn't boot and stops at BIOS error code 25h: Early PCI initialization: - Enumerate PCI bus number - Assign memory & I/O resource - Search for a valid VGA device & VGA BIOS, and put it into C000:0
From my testing it seems that there's something wrong with the first card even though it works perfect in a 2-way and 3-way setup. When the system powers up, the 3 other cards seem to start and spin up, while the first, even though it spins, doesn't make as much noise and doesn't generate as much 'wind'. I also have to move my monitor to the 2nd card or I don't get a picture...

Have you tried using the "bad" card on its own with no other video cards?

That same card works fine in the same slot in a 2-way setup...

Seems to me a Clear PSU Problem. Are you sure the two power supplies Are correctly connected? Meaning same Ground (that should be ok otherwyse you would not have a motherboard or other components by now. And maybe a lot of smoke ... ) And pin 14, the green wire for ATX power up and boot. Seems to me the pin 14 is not correctly connected on Both ATX connectors. Hence One of the PSU's that feeds the cards does not boot, does not deliver power. The fact that the fans do not work properly almost proves the point. By the way, Googling I found the same error 25 and somebody solved the exact same issue. Regards.

Did you actually checked for the pin's actual electrical connectivity with a multimeter ? These thing can be pushed and disconnected no matter what brand they are ... Do you have the link, I'm not finding it http://www.aoaforums.com/forum/epox-motherboards/39886-post-error-code-25-a.htmlCheck post 11,12 ... Regards.

It's fixed now. There's not enough resources available to start the machine when there 4x dual GPU cards installed. When I disable the F-USB3.0, eSATA3, GSATA3 and R-USB3.0 controllers in the BIOS, the machine starts up with all 4 cards...
It's working fine now...

I know your mobo is high end, But i've had a couple of broken gigabytes. I'd be using powered molex connectors on your extenders if i was you on at least 2 of them cards as they'll be drawing ALOT of power through the mobo. I had 1 board sending power down the EARTH and burn the 24 pin on my Akasa 1200W, which i now use just in the video cards and is fine. Just a word of warning from my experiences. Interesting someones got 4 of these beasts running in windows (8 GPUS). I feel for your wallet though..... i hope your doing it for the BTC and not profit...... at least until it goes back upto $5 at least with the cost of them beasts. I'd be suprised if you get 2.8G/hash out of it. Be nice see CGMiner with 8GPU's running in it

Just a word of warning from my experiences. Interesting someones got 4 of these beasts running in windows (8 GPUS). Why would you be surprise to get 2.8GH/s out of it? That's only 350MH per GU which is pretty easy for a 5970. I got 2.9GH/s out of 4x5970 but found 3x5970 to be "easier" (no need for powered extenders, ability to use single PSU, etc). To OP nice catch on BIOS resource issues. I usually shutoff all that extra junk just to save wattage. Never would have thought that would cause a resource limitation issue though.

I'd be suprised if you get 2.8G/hash out of it. Be nice see CGMiner with 8GPU's running in it BTC is one of the reasons, but this machine has other uses as well. And I get approx. 3G/hash out of it... I'll see whether I can get cgminer running, currently it's using GUI Miner.

Sounds good mate, Well done on getting it all going. I recon you'll squeeze a bit more than 3 with CGminer over GUI miner, there a topic about flags (1st page) in hardware, Should be near top as taxesanddeath and p4cman have a grudge about me giving advice and help because 'BTC's' are not worth mining. Maybe not in there world Taxes - 8 5850's Oc'd like mine will beat 4 5970's/6990's, at less than 1/3rd of the price. Why cant you accept that haha. Nevermind 5870's. They wont need OC'ing! No offense to the OP cause its nice see someone get 4 of them cards working. Hence why i help but finacially there a silly buy. Specially with the new lower price. It's because of people like you who whore your coins that they go down in price, and yet you moan the loadest... noticed that

Maybe not in there world Nobody has a grudge. You just foolishly tried to defend how mining at a loss makes sense because you can double your money and assorted other nonsense.

As it has been pointed out to you 5970s have be found in the past for $400 new and easily obtained used for $300 - $350. You did not find 5850s for $50 ea so your claim is false. Nobody is building rigs out of $700 GPU (except in your mind so you can "beat" them). 3x5970 = <$1000 MB, RAM, CPU, USB drive, LinuxCoin, 2x 120mm fans = <$240 1200W PSU = $250 Total <$1500 for 2.3GH/s and higher electrical efficiency than 5850s (a pair pull 300W+ without overclocking making them horrible for power efficiency). BTW still waiting on that 10 BTC you promised for finding you a 5970 (the card you thought didn't exist) for sale.

Stop blurbing, I DO ALOT WITH MY BTC's, that is what i said, AT LEAST DOUBLE THEM. Thats fact mate. You want a picture of how many i have as evidence or what. Will that be enough? haha. I changed that post quick time when i read it back as you noticed, i did get 5990 in my head, not 5970 i admit for a second. But it is the 6990 that replaces the 5970. And i live in rip off britain and i payed £120 each for the 5850's. I'm happy bro, More than lol. Back on topic, Wouldnt mind seen a pic of the rig if possible...

So hopefully the next time you decide to spam a thread off topic you won't make asinine references to stupid people using $700 5970s given that no smart miner pays $700. £120 a card? Thats what $180 ea or $360 per pair, plus worse efficiency and horrible UK energy prices on top of that. Maybe just maybe 5970s miners know what they are doing building ultra efficient rigs. Then again some of us want to mine at a profit not mine at a loss and then justify it.

Then again some of us want to mine at a profit not mine at a loss and then justify it. I use OCUK for reference, as there BIGGEST sellers in UK and i just noticed, they've stopped stocking the 6990, probably because of there £600+ price tag! I'm mine cause i enjoy it, because it takes the banks out of the loop and many other reason you people so obsessed with profit couldn't even fathom out. I give help and advice to people who want to push there hardware or whatever and you cant get it out of your head that i 'assumed' i was still making a profit. I would call it border line as i well over estimated things, so yes, i may not be making a profit mining at current price of BTC's but im in it for principle. I've invested in FPGA boards so have a bitch at me about them using to much power Here you go, silly money... http://www.amazon.co.uk/mn/search/?ref%5F=nb%5Fsb%5Fnoss&url=search-alias%3Daps&field-keywords=6990&x=0&y=0&rd=1

Here you go, silly money... http://www.memory4less.com/m4l_itemdetail.aspx?itemid=1453725275&partno=100282-2GVXSR&rid=fd_10Just because you can't find cost effective 5970s doesn't mean they don't exist. I have noticed how every thread involving a 5970 you make comments about the person throwing the money away, getting ripped off, should have used 5850s, and dual GPU are for clueless people. The reality is there 5970 is one of the highest performance per watt cards AND can be obtained for low cost per MH (at least by some people) AND has extremely high density. A win-win-win.

The main issue in the UK is availability, and this drives up the cost of dual-GPU cards to uneconomic levels. If you can find me a card with good availability in the UK, plus a price close to the prices you pay in the USA, then I'll agree with you about the 5970s. My point wasn't that you must use 5970 just pointing out his claim that 5970s are for idiots w/ money to burn are off base. The claim one can build a faster rig at 1/3rd the cost is also off base (outside of the UK). For those who have access (and there is a never ending supply of used ones on ebay) they are efficient, cheap, and very dense (2.3 GH in 6 slots w/o extenders). Remember that if we import from you, we get import duty and then 20% VAT bunged on top of the cost of the card, delivery AND duty. What about used? Is there still a 20% VAT and import duty? What if it was shipped as "non-functional" or "damaged" computer components? Being serious because if there is any ways around the 20% VAT & import duty I think there would be a way to circumvent the British blockade. If the import duty and VAT is ironclad well I agree 5970s simply don't make sense in the UK. It sucks when governments restrict free trade.
