EliteKiller Posted December 3, 2007 Share Posted December 3, 2007 If your +12V rail were truly that low you probably would not post. You can never rely on software voltage readings from Speedfan, Everest, MBM, etc. since they poll the info from the mobo in different fashions. Instead you need to use a DMM to test the 3 main rails. IMPORTANT - Testing Your PSU Rails Have you ever tested for stability using Memtest86+ or Orthos? How to guide: Memtest86+, Prime95, and SP2004 Link to comment Share on other sites More sharing options...
avata Posted December 3, 2007 Author Share Posted December 3, 2007 hi elitekiller yeah i know i shouldn't rely on software for level indicators....but in all the cases ive seen of people doing just that, the numbers they have seen have usually been only small % off from spec..i'm off by over 2 voltage points...now if that much of a difference in software monitors is normal, then wow...software monitors suck a big one. now don't get me wrong im gonna get myself a multimeter tonite and test them....but it just seems that even in speenfan a reading of 9.8v on a 12 volt rail shouldn't be happening.

Garvin Posted December 3, 2007 Share Posted December 3, 2007 If were actually that low, you wouldn't be able to post. SpeedFan and all other such utilities usually lag in the ability to read newer components by at least six months. They also aren't able to read all sensors correctly. It's usually best to check the site for their list of motherboards and components thy are capable of reading before installing them. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 3, 2007 Corsair Employees Share Posted December 3, 2007 Garvin and EliteKiller are right, if the 12v rail were really at 9.xx volts, the system wouldn't post. Let us know how you make out with the multimeter! Link to comment Share on other sites More sharing options...
