GPU speed sudden reduction - eliote - 10-31-2011
Hey all;
I've recently deployed a proper installation of oclhc using the latest ATI driver(regarding to my hardware) as well as STREAM SDK; which means I'm able to utilize my ATI Radeon 4670 hardware for recovering hashes.
The actual problem is, the first time I used the oclhc - right after the installation - the GPU speed was at around 247M/s(don' remember exactly), but after a system reboot, when I used the oclhc, the GPU speed has been drastically dropped to 19M/s.
could anyone help me with this problem? Is there any relation to the hyper-threading feature of my CPU? oh, by the way I'm using core i7 950.

please read this: http://hashcat.net/wiki/oclhashcat_catalyst_forceware
in short: install cat 11.4 + sdk 2.4 and try again

Is there any tutorial showing that how to clean UNINSTALL the previous versions of Catalyst and SDK?

With superuser permissions, enter the command: aticonfig --uninstall
for sdk you just need to delete the directories.

But drivers seems to be kinda stuck in the system, I've removed my previous installed drivers version- 11.9 - and then installed the 11.4 version over 3 times; each time I checked if the process went well, the Catalyst information shows that I still got the 11.9 version!!! which was not what I looked for...
I think It would be call as a mess up! right?

yeah, installation catalyst and SDK on linux is crazy. check if your distribution itself adds a catalyst package. maybe its enought just to remove it and then the cat 11.4 is used by the system. sometimes you also need to rebuild some init-ramdisk with "update-initramfs -u" but this is very specific to your distribution.
