Title: CGminer help
Post by: smracer on January 20, 2012, 05:07:56 PM

Hello,

I am trying to raise the Engine clock on some 5870's and everytime I try to go over 900Mhz it says

"Failed to modify engine clock speed".

I have seen tons of posts where people can go over 900Mhz. What am I doing wrong?

Ubuntu 11.04 on a 4GB USB Drive, 890FXA-GD70, 4X5870's, cgminer.

Thanks

Bo

I had problems getting CGminer to overclock my 5830s, in the end I gave up and did the overclocking myself... Running nicely at 950MHz [Running under windows though]

What driver version? I believe at some point the driver allows overclocking above the limit. I know 11.6 does.

Linux 2.6.32-5-686 #1 SMP Mon Oct 3 04:15:24 UTC 2011 i686 GNU/Linux
AMD driver ver. 11.11 && AMD APP ver. 2.5

just an example:

Code:

Adapter 0 - AMD Radeon HD 6700 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    1005           510
             Current Peak :    1005           510
  Configurable Peak Range : [500-870]     [510-1430]
                 GPU load :    99%
...

EDIT::Oh, since it isn't obvious from the uname output: it's Debian.
