The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

What is the proper AGP voltage?

Asked by kklarson in General Computer Systems

Tags: agp, voltage, hardware, proper

I recently purchased a new system including a Soyo KT400 Ultra motherboard and OEM Radeon 9000 4x AGP card (Sapphire).  The BIOS and Soyo Hardware monitor both reported that the AGP voltage was high at 2.0 volts, with the normal being 1.5 volts.  I tried manually changing the voltage in the BIOS, but that had no effect.  I contacted the seller who agreed that there was probably a problem with the motherboard and exchanged it.  Unfortunately, the replacement motherboard shows the same voltage reading.  I temporarily tried an old ATI Rage Fury Pro 128 2x, and the reading for it was 1.6.  I contacted the video card distributor.  Initially they said that this was a motherboard problem.  When I re-stated that the motherboard was replaced, the reply was:  "Well, all video cards draw its voltage from the motherboard if the motherboard reads 2.0 volt then I guess that's what the motherboard has distribute to the video board.  Remember these video card supports 2x=3.3 volt and 4x =1.5 volt so anything running between these numbers you should be safe."  Everything I have read states that the correct voltage is 1.5 and overclockers push is to 1.7 or 1.8, but I've not seen 2.0 as acceptable.  I don't want to burn out my video card and can't seem to get a straight answer on this.
