Title: 4870x2 only using 62% of one core? Post by: flyingmonkeycrap on May 12, 2013, 06:19:44 AM Hey guys,
I had a couple 4870x2s lying around so I decided I would give em a try mining (I currently get free power from school so not concerned with how inefficient they are). Well I hooked one up, installed the proper drivers and sdk, and started up scrypt gui miner. When both gpus are active, I get 100% usage on gpu0 but only 62% usage on gpu1. Seperatly I can get 100% usage on either one, however once both are active, gpu1 throttles to 62%? additionally gpu0 isnt coming out of its power saving mode and so while its mining the clocks are stuck at 500/500 (should be 750/900) any idea why? Thanks http://i676.photobucket.com/albums/vv130/airdraft/4870x2.png (http://s676.photobucket.com/user/airdraft/media/4870x2.png.html) Title: Re: 4870x2 only using 62% of one core?

Thanks http://i676.photobucket.com/albums/vv130/airdraft/4870x2.png (http://s676.photobucket.com/user/airdraft/media/4870x2.png.html) Disable ULPS (ultra low power setting) 1.Open regedit 2.Then select Computer>HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet 3.C+F "enableulps" 4.Change every value that comes up to 0 5.Press F3 to go to the next value. There will probably be a lot 6. Restart Title: Re: 4870x2 only using 62% of one core? Post by: flyingmonkeycrap on May 12, 2013, 09:10:03 AM Went through all the ULPS values and changed them all to 0 however it hasnt seemed to have had any effect the first core is still stuck at 500/500 and only ~60% of the second core is being used. Any ideas?
