I just got a Gigabyte GA-8IK1100 and installed 2 X 512MB PC3200 running Dual Channel on it. After a little bit, running programs that use a lot of ram, the programs crash. But when I only have 1 chip in, it never crashes. I have ran many RAM testers on my system and it only has errors when 2 chips are in. I'm not sure what the problem is, is it the MB, or is it the RAM, and what can i do to fix it. Thanks.
