Title: catalyst 11.12 negatively impacts mh/s? Post by: pandemic on January 13, 2012, 08:32:13 PM I just updated to CCC 11.12 and I'm getting about 10-15mh/s less now. Anyone else experiencing that? The only other changes I made was maybe a .NET update and a smaller PSU because my other one died.
Title: Re: catalyst 11.12 negatively impacts mh/s? Post by: DeathAndTaxes on January 13, 2012, 08:38:40 PM Yes. it is the SDK 2.6 you need to reinstall SDK 2.5 (or earlier) even uninstalling drivers won't fix this.
If you search the forum you can find instructions. Title: Re: catalyst 11.12 negatively impacts mh/s?

Title: Re: catalyst 11.12 negatively impacts mh/s? Post by: DeathAndTaxes on January 13, 2012, 08:50:35 PM so it's .NET? No it is AMD Open CL SDK. Each driver includes a specific version of SDK (AMD wraps them all together now). SDK 2.6 blows. The only solution is to get rid of it. Title: Re: catalyst 11.12 negatively impacts mh/s? Post by: pandemic on January 13, 2012, 08:56:10 PM gotchya. So uninstalling and reinstalling CCC 11 would resolve it then I assume? I wonder what they screwed up, lol.

I wonder what they screwed up, lol. No as I said in the first post if you do that it will keep SDK 2.6 and you will see no improvement. There are a couple of detailed threads with exactly step by step how to fix it. |
