Problem with volts, maybe?

post #1 of 3
Thread Starter 
I recently experienced a "lockup" while running a version of SETI@Home that has been optimized to take full advantage of SSE3 intel chips, the lockup was nothing new but it gave me the need to figure out why this is happening when I stress my system. I first thought it was an unstable OC but not now.



Got the lockup, decided to run a stress test to see if I could reproduce it and noticed that my volts are considerably lower than what they should be. System specs are in my sig, running Vista x64 Ultimate.

Could this be causing my lockups? Components requiring power that isn't there?
Am I using the wrong tool to measure this?
What would you recommend I use to verify my volts?

Check an empty 12v molex with a volt meter for true, accurate results.

If the 5V was at 4.56V and the 12V was at 10.65V then yes, you would be having major problems. Voltages need to be within +/- 5% so those would be very out of spec. But since using software to measure voltages isn't reliable, do like bill said check with a multimeter. Here's a nice guide: http://jongerow.com/BFGPower/troubleshooting.html#DMM
