i haf one piece of 1x512MB BT-D43 single sided..was shocked to received it as the other ram in the rig (my bros rig) is double sided, it cant dual channel due to tidak sama bank amount. So no choice take out one of my dual sided BT-D43, xchange wit my brother lo..cos im on SC due to 2.4C high fsb and BT-D43 cannot act on divider on DC and high fsb DC giving massive artifacts! But, tat single ram was able to cook way 270+ FSB on 3-4-4-8 SC with my other dual sided BT. Prob is, my cpu aint stable for more than 2hrs prime, only stable 1:1 at 264FSB, to low my low multiplier 2.4C, so now on 5:4 286:231 2.5-4-3-7 2.7V.
