Title: Crashes with Catalyst 11.5
Post by: Sjalq on July 13, 2011, 07:28:35 AM
Hi folks,

Since installing Catalyst 11.5 from the auto-updater my miner has been quite unstable over the past few days. Has any one else noticed similar instability with 11.5 or should I look for another cause?

Did you compare hash rates with 11.5 vs. 11.6?  I saw a significant decrease in hash power when I 'upgraded' to 11.6 on my 5870. From 440 MH/s down to 380 MH/s. :(

No decrease marked.

Check your AMD overdrive settings in catalyst, maybe they changed. (Performance -> AMD Overdrive)

You were right I did see a decrease, as fas as I can tell it was because the over clocking settings under "Performance -> AMD Overdrive" set the additional power back to 0% as opposed to + 20% where it was and because the clocks were set down from what their max was.

Please remember to use this in conjunction with MSI Afterburner to fine tune your fan speeds.
