Q6600, Abit IP35-Pro, and Voltage Levels
Last response: in Overclocking
Specs:
Q6600 G0 stepping
Abit IP35-Pro mobo
2x2GB G-Skill DDR2 800 5-5-5-15
Visontek HD 4870
Corsair 750w PSU
I'm new to OCing so I started off just taking the Q6600 up to 3.0GHz (333 x9) which was successful without a hitch. Now I'm trying for 3.2 and seem to keep running into problems. I tired 400fsb x8 but it wouldn't boot, I read that the P35 boards sometimes don't like 400+ fsb so I tried 355 x9 which boots up fine. Temperatures are all good (43-57C in Prime95) but on the second Prime95 test (length 8k) my voltage alarm goes off. I have it set to:
CPU Core: 1.305 V
DDR2: 1.8 V
CPU VTT: 1.2 V
MCH (NB): 1.25 V
ICH (SB): 1.05 V
ICHIO: 1.5 V
The alarm only goes off once all threads are on that 8k length test and ends the second I stop the test. CPU-Z reads a Core Voltage of 1.27 V at the time. Am I doing something wrong? Or is it possible I have a faulty sensor? Any help/advice would be appreciated.

More about : q6600 abit ip35 pro voltage levels
I am pretty sure P35 has no problem with 400+ fsb, that was the nvidia ones that had that issue. The Abit IP35 Pro can hit 500mhz+. I also own the IP35 Pro and Q6600 combo and I hit 3.6ghz (400x9) no problem. Hitting 3.7ghz was a bit harder and required a fairly high voltage increase. 3.8ghz however required almost least 1.6v any more voltage than that I would bsod. My temps were ok the entire time. Turns out that this board can't hit the super high clocks with quads because it has 4 phase pwm instead of 8 phase. Due to this anything above 3.6ghz is a battle. I know this isn't entirely relevant but I just wanted to give you a heads up.
As for your problem the IP35 Pro has a pretty bad vdroop issue. Try upping your voltage a bit and see if you still get the alarm. If you can't get rid of it you can disable the alarm in the bios.
