Topic: Sapphire 5850 dummy plugs? - page 2. (Read 10355 times)
I only used one resistor on the DVI plug attached to the card. I use three on the VGA side of a dummy plug. Maybe one would work, maybe it wouldn't. The information I had said to use three, so I use three. If resistors were $4/ea. it might matter a little more, but they're like $0.89 for 5.
So why does everyone use three resistors when I hear that just one works fine? Or is that the reason that elcasey's card blew - he was just using one, so it was an uneven resistance load on the card between the three channels?
It shouldn't make a difference whether you do it on DVI or VGA - they use the same wires, VGA just extends and reorganizes them.

People are putting resistors across all 3 channels, but they don't need to. I'm running 3 x HD5870, one with a monitor and 2 with 1 x resistor across 1 channel.

If you're using Windows you have to 'attach' the dummy monitor in the properties tab, so that Windows will use it.

Careful with DVI dummy plugs, if you short one of the resistors it can blow the video card itself. The VGA guys are far safer, at worst you're out just the adapter.
The 4 pins and earth 'cross' are the analogue output from the HDMI port. You are putting a resistor across the same pins, so it doesn't matter if you do it on a VGA plug or on the HDMI port. As long as there is a resistor across the R, G or B channel, Windows thinks you've got a monitor attached.
oh boy, you just killed a bitcoin-dummy-plug industry in its infancy, how cruel.
HAHAHA!
Just trying to help, and you know some people are always going to think that's too complex or dangerous for them, or are just plain lazy (nothing wrong with being lazy if you're willing [and able] to pay someone else not to be!).You guys can feel free to send me money to make these for you!
Dummy plugs go for around $4.50 (including resistor cost), shipping + materials (padded envelope) is $9. So we're looking at $13.50 my cost for shipping one of these to Estonia.
So if you're up for one for 2BTC, I'm willing to do it. I'll ship one out within 1 business day of receipt of payment. Just PM me on here for payment details and to confirm that you've sent payment.
If you can find someone to make one and ship from Europe I think it'd probably be a much better deal, but I'm happy to help. I just can't let it cost me money, as I'm sure you understand.

This is what I'm using now on 2 other cards - no problems whatsoever.

If there's still some interest in a few days I will figure out how much dummy plugs and resistors cost me and ship a few (worldwide).
I would just like to confirm that shorting the DVI connector on the card itself can destroy the card. Because it happened to me. Sapphire 5770, used a single 68Ohm resistor, card showed up in Catalyst and poclbm, seemed to be working fine ... and then I had to reboot for an unrelated reason. Win 7 would hard lock within 60 seconds of login. Even the reset button didn't work (which I didn't even think was possible). Pulled the card, works fine. Just got a replacement after ~2 weeks. How much money did that cost me, losing ~178MH/s for 2 weeks? So it's not worth it, boys.
I used this 5 Second Dummy Plug guide. It seemed like sound reasoning, but don't bet on it.

PM if interested in dummy plugs, I think I have 2 or 3 extras. 75 Ohm is the "ideal" resistor, apparently, but my local Radio Shack only stocks 68s and they seem to work fine. It's not hard to make them and 5 resistors cost a buck.

Is anybody shipping these to Europe?
I insulate between resistors. No Worries!

O_O That did it! I didnt know you had to enable the cards displays. Thank you!!

Ive got some trouble in relation to this too, Ive got 68 ohm resistors and dummy plugs for my cards, but in the guiminer only one of the cards is shown to be able to mine. Im running Windows XP Pro (because I had it laying around) and the newest catalyst/OpenCL. One card will mine, but the other three arent an option even with dummy plugs. I plugged in my 2nd monitor to the 2nd card, and still no display output. Im NOT running these in crossfire, but Ive got 4 Sapphire 5850s in this machine, and only one works. Is this an XP thing? In the device manager all 4 cards show up, and all show to be in different PCI-E slots. Im not sure what Im doing wrong...
I'm selling dummy plugs for .8 BTC each or 6 for 4BTC. Free shipping in US.

Do either of you give discounts for buying more than one at a time? I imagine shipping would be a fixed cost...
.8 BTC or 6 for 4BTC.. Shipping is free in US .5BTC Canada should do unless you order > 24...

Anybody here still selling dummy plugs?
I am selling the resistors to build dummy plugs for bitcoins. Well at least at the current exchange rate... less then .4 btc shipped.
http://cryptoanarchy.us/
I am also shipping to Canada for the same price, .99 cents in BTC. So currently 3 resistors shipped is around .35btc plus you can add a bumper sticker for about .2 btc.
I will ship to Canada. Just send an extra .5BTC.
Excellent. I don't need the plugs right now but maybe in a week or two when I can find a second cheap 5870 (motherboard doesn't support crossfire -hence need for dummy plugs). I'll PM you then if that's alright with you.
Cheers!
No problem. Let me know when you are ready.
