If anyone wants to sell resistors, put up a job on forbitcoin.com!

You can rest easy there as it's an escrow service

One interesting thing to note... dummy plugs are usually NOT required if you run a single card system with no monitor attached.

I realize that but I'm adding a second card
and we all know what happens in WINBLOWS

With current btc to dollars it really hurts to get screwed so bad for 3 resistors on a $1 plug
didn't mind a little for time & postage but $50 hurts especially not getting anything
Either negotiate with the seller or buy them at radioshack.  Problem solved.  No reason to spend $50 on them...

Just go to radio shack and get the 68 ohm 1/2 watt resistors, a 5-pak is $1.19 USD. It only takes 3 to bend and stick in  . . sooper easy works like a charm! I just did it today! Good luk!

Damn, that sucks. Hope you get this issue resolved somehow.

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....

I'm selling dummy plugs for .8 BTC each or 6 for 4BTC. Free shipping in US.

Send Coins to 12h4UCpyxpEzKcQZMifXNyEAqRM17i4JY1

PM me with your mailing address and amount sent

lol. a price war for dummy plugs is about to start Wink





Do either of you give discounts for buying more than one at a time? I imagine shipping would be a fixed cost... Smiley

.8 BTC or 6 for 4BTC.. Shipping is free in US .5BTC Canada should do unless you order > 24... Grin

Dafishman

how about no shipping period

anyone ever get what they ordered from this guy ??
three wks now and a couple bit coins later

no delivery ... no pm ... took the money & ran

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.

How do you know if the dummy plug is working or not?

You'll be able to see the second card as a valid OpenCL device without having to plug a monitor into it.

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.

3 resistors is needed when you use a DVI-VGA adapter.  1 resister is needed if you plug the resistor directly into the graphics card.


Here is the guide to the 3 resistor dummy plug.

Not true. You only need 1 resistor in either case. 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.

You sure about that? I never had to attach a dummy monitor *shrug*

I did in Windows XP to get BFI_INT to work, but this may not be the same for all Windows OS if others haven't needed to.

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 Tongue
or by card BIOS adjusting ?[RBE ?]

this thread took an interesting turn. I never figured out why it wouldn't work.

oh well. on linux now and loving it!

Did you read my original post?

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:

i.e. In Windows just the dummy plug isn't enough.

I saw your post, that probably would have fixed it but I already have both my rigs headless through SSH - not going back now! Smiley

Ha, that it did. I hate when someone asks a question and all the replies are basically "Works For Me (TM)". But I guess that's exactly what we did, as well as shameless advertising.  Tongue
