Title: Instead of GPUs - PCI based Mining hardware? & Non tradidional PCs Post by: Zillions on August 27, 2012, 03:53:58 AM Ok stupid question considering you need a computer to run all current hardware to run any of the stand alone mining hardware.
Why hasn't any one made a PCI based card to mine coins? Yes it's more power efficient but if you just plug a card into your computer that has a already being used PSU, why do I need to have another power leeching wall wart? Is there any one that I could contact for such a thing to get one made to get the ball rolling? Maybe get a kickstarter program going. If any one that is designing the Opensource hardware could we maybe get a vote going what style of hardware you'd prefer? Title: Re: PCI based Mining hardware?

Title: Re: PCI based Mining hardware? Instead of GPUs Post by: crazyates on August 27, 2012, 04:25:39 AM I'm gonna guess and say USB controllers are cheaper and easier to work with than PCIe controllers. The KISS rule always trumps.
Title: Re: PCI based Mining hardware? Instead of GPUs Post by: pieppiep on August 27, 2012, 04:57:45 AM The cooling of my computer isn't the best. I don't want another heat producer inside it.
Besides, for the people who really want to mine big, the total number of pci/pci-e/whatever type of cards is limited to a very low number. usb goes up to 127 devices each controller.

it's possible to use a DD-WRT based router instead. Title: Re: PCI based Mining hardware? Instead of GPUs Post by: Lethos on August 27, 2012, 07:56:29 AM As already mentioned, using usb is just a little easier all round.
But enterpoint as a long time maker of general use FPGA's makes all kinds, they have done really big chip arrays that are PCI based. http://enterpoint.co.uk/products/asic-development-high-performance-computing/merrick-3/ Their merrick-3 is one of their biggest spartan 6's and when it came to entering the bitcoin market, they still choose an entirely new design which was USB based. So if you want a concrete answer I'd ask Yohan at enterpoint why. Title: Re: PCI based Mining hardware?

If I remember rightly, the molex connect can handle 5amps on the 5v and 12v line, so you looking at: 60w and 25w. Then you have the PCIe itself, so that is another 75w. So short answer, is no. I'm not seeing how they could do it, with just 1. But not all spartan 6's use 10watts. Title: Re: PCI based Mining hardware?

Lets say the did use XC6SLX150 chips (What the ZTEX, ModMiner, Lancelot, Icarus, X6500, and Cairnsmore all use), but not a full 24. They could fill half the board and use 12 chips, and have the card draw < 150W for 2.4GH/s. It'll cost you 3x any of the previously mentioned chips, but hey, who cares? :P Title: Re: PCI based Mining hardware? Instead of GPUs Post by: Zillions on August 27, 2012, 07:19:48 PM Power? We just plug another molex into the card just like we power video cards nowdays.
My whole thing is I still need a fully functioning PC to do mining some what of a waste I used to power my PC down every so often but now leave it on constantly. I have a 850w power supply and would love to just throw in a couple PCI cards into empty slots to fill out. I know somebody has done a rasberryey pi (honestly no idea what OS) but some one just mentioned that they used a DDWrt router to mine wth how'd you get that running is there a guide you can point me to? I have 2 old routers that I believe can be ddwrt'd that I'd love to conver into low power dedicated miners. Any channce for a couple of links? Also I can't find it right now but I heard some one was working on an android mining clinet? that would be awesome as I have a tablet that's basically a Alarm clock bedtime webrowser/video player. Title: Re: PCI based Mining hardware? Instead of GPUs Post by: crazyates on August 27, 2012, 08:16:45 PM Lets take these things one at a time.
Power? We just plug another molex into the card just like we power video cards nowdays. That's what we're discussing. The board he linked only has 1 molex power plug.My whole thing is I still need a fully functioning PC to do mining some what of a waste I used to power my PC down every so often but now leave it on constantly. I have a 850w power supply and would love to just throw in a couple PCI cards into empty slots to fill out. There is no such product out there right now. Realisticly, if you have empty PCIe slots and a PSU to power them, start buying more GPUs!I know somebody has done a rasberryey pi (honestly no idea what OS) but some one just mentioned that they used a DDWrt router to mine wth how'd you get that running is there a guide you can point me to? CGMiner on a DD-WRT can be found here (https://bitcointalk.org/index.php?topic=76685.0). A RPi guide can be found here (https://bitcointalk.org/index.php?topic=69183.msg919685#msg919685).

Assuming you're not actually trying to mine on the tablet itself (you're talking piddly squat for performance), the problem with that is that most Android phones/tables do not have a USB host controller. If you found one that could act as a USB controller and not a slave, you could possibly hook up an FPGA and run some mining software. If you're really serious about that, I'd start a new thread, and maybe check out this (http://www.ubuntu.com/devices/android). Title: Re: PCI based Mining hardware?

I was about to get all excited when I said myself "Sure I have a USB port on My Asus Transormer Prime!" then realized that the charging port was what connected to the USB for data transfers too bad I don't have the docking station might be the perfect low power PC.

I've seen a lot of people use old laptops when mining with FPGAs (or just use whatever they have. Any old dell you pick up on ebay for < $100 with working USB and LAN ports can run Ubuntu and mine with as many FPGAs as you want. And when they idle at < 20W, the power cost is pretty small.

If you want to spend $100 on a used one, you might as well pick up a cheap, low power laptop (https://bitcointalk.org/index.php?topic=102144.0), and not worry about the extra 10W power draw. ;)Title: Re: Instead of GPUs - PCI based Mining hardware? & Non tradidional PCs Post by: Zillions on August 28, 2012, 11:14:50 PM Like what? a netbook?

IIRC laptops and netbooks still draw40w-95w depending on the AC adapter. What? My netbook draws 12W. It's only got a 35W adapter! Yes most smaller laptops will have a charger somewhere in the 60-95W range, but that's MAX LOAD! That's like saying my desktop tower with a 1000W CM PSU uses 1000W. A laptop mining on a bunch of FPGAs will not use 95 or even 60W.

Has any new options opened up that I'm not aware of? I see very little alt coin development is that because this site is more geared toward bitcoins?

I'll have to look into VMC never heard of them. |
