I've always wondered; what does the DDR2 REF percentage do?

you need 50% of your ddr voltage to be supplied to the dimms to function properly...this becomes very important when you overclock the dimms...so...that percent tile for DDR2 REF is an adjustment factor for that 50%...i always go for the +2%....never set anything less than 0%.

while we are talking about ddr voltage...i measured mine on the board and it is spot on with what i set in Uguru...i've read at least one poster in another forum complaining that his ddr voltage was sligthly lower than what is set...it just goes to show you how the same board can vary in performance for each user.
