Hi yall! Decidet to post a separate Thread for this! 1.) In my older desktop I have a 2GHz Celeron (20x 100MHz) Well - the bios lets me change the FSB and right now it's running at 2.20GHz - plays 360p youtube with no stuttering (2GHz = %100 CPU 2.2GHz = %91 CPU utilization) How far can I go? (133 didn't work!!!! - black screen....had to clear CMOS) 2.) Also - the Fan on this PC (Motherboard: 8VM533M-RZ newest Bios) is always at %100 - no option in the bios that lets me change it - All drivers up to date, newest Bios - looked everywhere - nothing FAN / SPEED related........it's a Stock Cooler MAster Socket 478-FAN. It's 3 pin and i have already tried everything in my toolbox to fix this......It has a 266 Via Chip, which i have had on my previous AMD-Athlon XP rig - it did support Fan speed adjustment. Temps are 25c - 40c RPM: 3000 It has temp 4 sensors all under 40c new thermal paste already applied.....ANY IDEA why the fan is always on %100 speed?? I have also already tried a different FAN..... Appreciate every bit of help!!!!
