For three channel memory which would be best: Three, two gig modules (one per channel) or six, one gig modules? Also, if the modules run at 1.65 v. can this be provided in the BIOS without selecting other component, such as CPU, voltages?
ll six DIMMS draw more voltage than three and, from what I have read, sometimes need a core voltage boost to remain stable.
2 sticks or 4stick should use pretty similar voltage since all RAM is rated at same voltage. When you need more DRAM voltage is because you are using overclock (changing specs of RAM). Try at stock voltage, should work without problems.
