Dual Channel Problems

  1. Okay, I am trying to upgrade from 1 stick of 512 MB RAM (RAM: 1 x Kingston 512MB Non-ECC, CL3 PC3200 DDR 400MHz) to 1GB. I first purchased another stick of the exact same type of RAM, installed it in DIMM 2. This made the system unstable with blue screens, reboots, etc. I installed and ran MemTest 3.2 and came to the conclusion that the second stick I just purchased/ installed was bad. The mem test resulted in many errors.

    I sent that back to where I purchased it and ordered a 1GB kit (2x512MB). I took out the 1 lonely original stick of 512MB and replaced it with the 2x512MB sticks, DIMM 1&2. The system is now unstable. I ran MemTest3.2 on both sticks independently and they both came up with errors. I have since put my original lonely stick of 512MB back in and the system runs fine. I am going to return the 1GB kit.

    Is it possible that I am not setting up the bios correctly for Dual Channel or to handle 1GB? What is the trick to install Dual Channel efficiently?

    I can't believe that I have purchased 3 bad sticks of RAM in a row!!

    For dual channel mode you need to install the RAM in slots 1 and 3 or 2 and 3. Abits web page should have a list of RAM that was tested with your board. Ive heard of problems with double sided RAM in newer boards.
