Title: Sapphire 5850 dummy plugs? Post by: csshih on May 15, 2011, 12:32:07 AM Hey all,
Has anyone else been having problems with getting dummy plugs to work with their Sapphire 5850s? I've just about given up on them as I should be doing everything right! 74.8 ohm resistors, I've tried 3 resistors and 1 resistor, I've even tried adding solder to the leads to assist in connection. nothing. I've tried all 3 adapters (DVI TO VGA) to no avail... plugging in a monitor works, though! strange! Craig Title: Re: Sapphire 5850 dummy plugs? Post by: Kick on May 15, 2011, 12:47:49 AM dummy plugs are there to emulate a monitor if you didnt figure that out.
u can always just plug a monitor in start up miner then unplug it Title: Re: Sapphire 5850 dummy plugs? Post by: csshih on May 15, 2011, 12:59:41 AM right. I'm trying to avoid doing that every time I start up the PC.

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! Title: Re: Sapphire 5850 dummy plugs?

Post by: um0rion on May 17, 2011, 09:14:57 PM 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...
Title: Re: Sapphire 5850 dummy plugs? Post by: TenthReality on May 17, 2011, 09:34:18 PM If you're using Windows you have to 'attach' the dummy monitor in the properties tab, so that Windows will use it. This is the dummy plug I'm using: http://blog.zorinaq.com/?e=11 (http://blog.zorinaq.com/?e=11) 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. Title: Re: Sapphire 5850 dummy plugs? Post by: um0rion on May 17, 2011, 09:50:32 PM O_O That did it! I didnt know you had to enable the cards displays. Thank you!!

Title: Re: Sapphire 5850 dummy plugs? Post by: elcasey on May 18, 2011, 02:41:00 PM 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 (http://blog.zorinaq.com/?e=11) guide. It seemed like sound reasoning, but don't bet on it. This is what I'm using now on 2 other cards (http://www.overclock.net/folding-home-guides-tutorials/384733-30-second-dummy-plug.html) - no problems whatsoever. 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. Title: Re: Sapphire 5850 dummy plugs?

Title: Re: Sapphire 5850 dummy plugs? Post by: elcasey on May 18, 2011, 02:57:23 PM 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. Title: Re: Sapphire 5850 dummy plugs? Post by: elcasey on May 18, 2011, 02:59:12 PM oh boy, you just killed a bitcoin-dummy-plug industry in its infancy, how cruel. HAHAHA! ;D 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! 8) Title: Re: Sapphire 5850 dummy plugs?

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. Title: Re: Sapphire 5850 dummy plugs? Post by: SgtSpike on May 18, 2011, 06:01:30 PM 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. Title: Re: Sapphire 5850 dummy plugs?

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. Title: Re: Sapphire 5850 dummy plugs? Post by: elcasey on May 18, 2011, 06:10:08 PM 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.

Post by: Basiley on May 20, 2011, 04:22:04 AM there is no way to just tweak Windows registry to ensure catalyst thats monitor was plugged-in and card must be operational ?
anyone there with Catalyst inner space knowledge can confirm/disagree with that ? or someone with DDK/disasm/debug skills :P or by card BIOS adjusting ?[RBE ?] Title: Re: Sapphire 5850 dummy plugs?

HDMI plugs have analogue outputs as well as digital ones. The converter just converts the connection type from HDMI to standard VGA. All you are doing is putting a resistor across the Red or the Green or the Blue channel (or all 3 if you use 3 resistors). These are the same channels at the HDMI output as the VGA output on the converter. Title: Re: Sapphire 5850 dummy plugs?

Title: Re: Sapphire 5850 dummy plugs? Post by: allinvain on May 25, 2011, 04:13:13 AM So do you need one dummy plug for each card? Someone else said you can just do 1st card for 1/2 and the 3rd card for 3/4. You only need dummy plugs for secondary displays/cards. What I mean by that is that there will be one card that is always active as the system display card. That one does not get turned off by the drivers when no monitor is connected to it. I dunno about 3rd card for 3/4..I never tried it with 3 cards. I do use two cards per system so I use the dummy plug on the second card. Title: Re: Sapphire 5850 dummy plugs?

Having read this I am glad I decided not to buy from this guy. I instead ended up searching on ebay and ran across some guy who runs this site: cablesaurus.com I ordered two dummy cables from him for a reasonable BTC price and I just received them today. I'm wondering if the admin of that site is on this forum.... Title: Re: Sapphire 5850 dummy plugs?
