ollehto Posted July 14, 2009 Share Posted July 14, 2009 so here is my problem in a little more detail having a perfect install after following DigitalDreamers guide for this mobo, i had to do a reinstall after a disk failure. reinstalling the same way using the script chameleon 2 and a dmg of my 10.5 retail instal disk + 10.5.7 combo update. in this new instal im experiencing a sever decrease of performance. First of all, only 4 cores are detected even though hyperthreading is enabled in bios. secondly, playing games like COD4 results in extremely varied fps rendering the game useless. same experience in geekbench and xbench which will output at its best only half the score of what it used to and at its worst something more like a G4 PPC. i have tried updating the bios with several different ones including reverting back to the original without that making any difference reinstalling again produces the same result. on my windows7 install everything is working as it should so it cant be hardware failure anyone with similar experiences? or a clue for what to do or where to look? here is 3 xbench results made with a minute pause in between each one. no other programs are running strange..?
