Hi Guys, I'm currently using 2 x 512MB sticks of RAM in my Asus P5AD2-E (i925XE). I want to go up to 2GB of RAM. Are there any disadvantages running 4 sticks as opposed to 2? Not interested in whether the RAM won't overclock as well, I'm running it well within its capability (550MHz DDR 1:1) at the moment so that won't be an issue - I'm more interested in whether anyone knows whether PAT is disabled with 4 sticks on the i925XE chipset/etc ... or anything else like that. Cheers, Gibbon.
