Hi, I have the Dfi Ultra-d with a Venice and 2x 512 G.skill GH sticks. My ram does 260mhz 1.5-2-2-5 1t 24/7 I have ordered an Opteron 146 becouse for its nice overclockability an for its 1mb L2 cache that i will be neading when upgrading to 2gb of ram. My cuestions are: 1. Will 4x 512 run in 2x dualchannel? 2. If 4x 512 wont do dual channel would 2x 1gb, in dual ch, be faster? Kaeping in mind that the 512's will overclock better.. 3. Will 4x 512mb sticks overclock as good as 2 sticks? I know that i can go as fast as the slowest stick but are ther any known isseus that prove not to run 4 stick together? Any opinions welcome becouse i dont have a clue..
