http://www.xtremesystems.org/forums/showthread.php?t=81429, following this guide here i installed the hotfix and the dual core driver and optimizer a few weeks ago after a fresh install, all was good until i started getting random pc lockups, and just recently stutters in bf2 etc. I do have my cpu overclocked but this can't be the problem as i have sp2004'd it etc all seems stable and i got these problems even when it was at stock, so using that guide i uninstalled all the drivers hotfixes etc and suprise suprise i get no freezes etc so far, i wont hold my breath as these have plauged me for week's popping up at random times so could still pop up at any minute. I ran 3dmark 05 and 06 as soon as i booted up without the hotfix, driver and optimizer suprise suprise i got 30 points more in 05 and 10 more in 06, fair enough this isnt a big gain at all but it brings up the question, what really is the point in this driver, optimizer and hotfix?.
