Recently I was troubleshooting some hardlocks that have been happening on my Vista Ultra Sli Nvidia ultimate gamer rig (tiger direct special) its got a Core Two Duo 3.00 ghz processor, 2x nvidia geforce 9600 gso graphics cards in Sli configuration and I had to replace the 4gb Crucial Balistix Tracer ram with corsair Xms2 ram .. the old sticks went bad and were found faulty by Windows memory Tester.
I was troubleshooting the Hardlocks .. and what seems to keep it working the longest was a tweak to the power management section so it wont sleep but during the Trouble shooting phase I ran a program Cpuid and it says that my Twelve volt power supply is givng only 10.37 volts. The psu that came with this pc is a 600 watt OCZ model ocz600mxsp and is 80 plus certified .. Could a 12 volt rail this low be the cause of some issues and is it worth replacing the psu?
Good replies so far I was wondering if I didnt jump to too many conclusions from just the one test so far I have been browsing Nvidia for a untility for power supply testing. I have checked the bios before for voltages but havent seen it yet, I will look again tho. I tried the Occt stresstest .. I must admit I got a bit Squemish when I saw one of my temps on my gpu go up to 71 I am guessing that is celsius so I stoped it short at 7 minutes .. one card is running ten degree's hotter .. but thats probaly not a real issue .. maybe I didnt get enough dust out of the fans.
I can run it more for the sake of a better picture but even in that short time its showing a trend of under voltage .. if there is anything else I can try .. or run it longer let me know
Thanks for the replies I got the Multimeter and the 12v rail is giving 12.29 I guess I have to take these programs with a Grain of salt .. --- my pc hard locked during this reply so I guess its back to square one .. when I saw the voltage was out or range on that program I was hoping it was the problem .. too eager to check the certainty.. at least its not every five minutes when I boot up .. thanks for the replys .. I will have to keep looking
