Title: win 7 x64 , 4 cards fine, last one (fifth) with code 43 :(. Bounty Post by: novymivo on January 17, 2014, 03:29:53 PM hi all
I making my first rig with 5 gpus. I used amd r9 280x with catalist 13.06 beta, but last one card got code 43. Card is ok, slots as well, motherboards as well asrock btc 81. Which drivers i should use ? do I need SDK or what ?? Tip will be given to for right advice. Kind regards Title: Re: win 7 x64 , 4 cards fine, last one (fifth) with code 43 :(. Bounty Post by: nachius on January 17, 2014, 08:04:46 PM If you are sure the card is good ie tested in another slot and you know the slot is good ie tested another working card in that slot then it should not be the drivers or sdk. It could be your Intensity or thread concurrency, but start with hardware info:
How much system memory and what is the power supply? Title: Re: win 7 x64 , 4 cards fine, last one (fifth) with code 43 :(.

It could be your Intensity or thread concurrency, but start with hardware info: -pcie slots checkedHow much system memory and what is the power supply? -risers checked -gpu-s checked -psu lepa 1600 -4gb dual ddr3 or something like that :) When I try to connect fifth card then one is off with error 43 is visible in devices list but off due to error 43. I ve been told that win 7 support only 4 gpu like r9 280x. I am downloading now catalyst drivers 12.6 - someone gave me that advice. Any more info will be appreciated Kind regards Title: Re: win 7 x64 , 4 cards fine, last one (fifth) with code 43 :(.

It seems to be board dependent on boards tha twill run more than 4 gpu cores from this thread. I didn't look specifically for your board, but catalyst driver, sdk, motherboard all seem to factor in.

Bounty Post by: novymivo on January 18, 2014, 04:54:55 PM Catalists 12.6 + SDK 12.7 + cgminer 3.7.0 (not 3.7.2) = 5gpu on win 7 :D
DONE BUAHAHA r9780x is seen as r7990 Title: Re: win 7 x64 , 4 cards fine, last one (fifth) with code 43 :(. Bounty Post by: nachius on January 20, 2014, 04:16:06 AM Good to hear and I'll keep this thread for reference for the sdk/catalyst driver combo if I decide to build a 5+ card rig. All my rigs run 3-4 cards....

I have 3 R7990's and 2 work sweet (4 gpu's). Since 1 7990 is 2 gpu's it would make sence why I've been fighting with getting the 3'rd one working (total of 6 gpu's), never knew there was a limit. I'll go from here! thx

I had 5 cards and all were detected but 1 of them would not load the drivers. Updated to Win 8.1 and everything worked. I had tried everything up to that point. (old drivers, new drivers, switching cards and pcie lanes.)
