-12v goes all the way to -13.3 on the abiteq reading. Is it bad?

[nowallet]

Here is my setup:

1. nf7-s
2. kingston 2x256 value ram pc3200
3. barton 2500+
4. antec 350 smartblue psu

When I try to overclock to 3200+ the system is unstable. the vcore reading is at 1.67v. Tried to increase the voltage on the vcore to 1.725 but it doesn't seem to help. What might be the reason why my system is unstable? Please help. This is my first custom built unit.

The minus 12v isn't used on current systems anymore, they just include the output for 2 reasons: 1.The ATX specification calls for it. 2.Someone might want to buy a new psu for an old computer. And if you want to be able to hit 200mhz fsb, you need to raise your vcore (cpu voltage). Most people, with the latest Baron 2500's are needing between 1.75v & 1.80v to make it to 200fsb stably.

thank you for your input myocardia. But from reading several threads, people seem to overclock to 200mhz with stock voltage and it is running stable on their system. I hope it is not psu that is causing the problem, if so I can return it now rather than regretting it later.

That power supply should handle what you have with no problems whatsoever, but if you think it's the psu, check your voltages with the cpu under heavy load. I would download Prime95, and use the "maximum heat" portion of the torture test. By the way, what are your temps running? Oh, and the people who say that they are hitting 200fsb on stock voltage aren't the people who just bought their processor, they are the people who got the earlier ones.
