Title: Which version of Catalyst do not require dummy plugs ? (hd 7950s) Post by: N1CKH0LAS on May 27, 2013, 04:02:49 PM I have 13.2 beta and it still require dummy plugs, for a couple of hd 7950s. If there's anyone that's using multiple GPUs without dummy plugs, please post here your catalyst driver version and SDK. ( windows )
Thanks in advance :) Title: Re: Which version of Catalyst do not require dummy plugs ? (hd 7950s) Post by: miningdude on May 27, 2013, 04:36:17 PM I'm using 13.1 on Sapphire 7950's. Full build list at http://www.coinminingrigs.com/quad-7970-mining-rig/. No dummy plugs were required, though once I did have to temporarily plug in a monitor on one to 'activate' it.

It seems 13.1 works ( tested it today ), but i get way more "display driver stopped responding and has successfully recovered" messages than before. For example, after I close cgminer, the driver always crashed, then recovers. It didn't happen with the 13.2 beta drivers.
So, any other driver that works without dummy plugs ? Title: Re: Which version of Catalyst do not require dummy plugs ? (hd 7950s) Post by: nwoolls on May 28, 2013, 02:55:55 PM I use 12.8 without dummy plugs with 2 GPU's (7950's). No crashes unless I'm messing with stuff ;).
Title: Re: Which version of Catalyst do not require dummy plugs ? (hd 7950s) [Solved] Post by: N1CKH0LAS on May 31, 2013, 12:19:46 PM Thanks both of you for answers. I can confirm both 13.1 and 12.8 versions do not require dummy plugs, at least with 7950 cards.
I've changed the title to [Solved] Title: Re: Which version of Catalyst do not require dummy plugs ? (hd 7950s) Post by: HellDiverUK on May 31, 2013, 12:24:40 PM I've never needed dummy plugs? 12.4, 12.8, 12.10, 13.2.....Windows 7, Windows 8....6 different ATI cards from a HD5870 to a HD7950....
I don't understand why people think they need them? Title: Re: Which version of Catalyst do not require dummy plugs ? (hd 7950s) Post by: deslok on May 31, 2013, 01:18:59 PM Most of the 12.x and 13.x driver revisions shouldn't require dummy plugs but i've found even though we're not supposed to need them does not make them useless, as a side note i advocate 75 ohm resistors in place of plugs due to their absurd cost.
