err.... swaping out a70 for . d14? I hope u plane on changeing out the fans too. your swaping for a sideways swap. noting going to improve much.
Anyways on point. I had 2 920 c0 and 1 920 do and now on 930 do.
920 c0 chip 3.8 ghz @ 1.4 volts.
920 d0 chip 4ghz @ 1.38 volts.
930 d0 chip 4ghz @ 1.2785 volts
Now i got 6 gb of ram across all 6 dimms , qpi volts are 1.35-1.40, all depends on all system components but the volts your going to get is different. Mostly if i where you. strat with low volts @ stock and see how low u can run stack @ lowest volts to run,
920 was 1 volt
920 do was .975
930 is .925 volts @ stock
it lets you know a little more about your chip @ start. the lower the volts are @ stock the higher in the end u mite be able to take it faster. I know i dont have your mobo but its the same chipset. i say looking @ my other chips . U can hit 4 ghz on it @ high volts but i like my chip to hit a max of 70 degs so for me thats my limit. i can hit 4.2 on this chip but in folding it hits 75 degs
so i got it @ 4 ghz.
hope you good luck .
Good cpu stress tester is . Linx cpu stress. i do 10 runs for fast. then 500 do make sure @ the volts/speed is recorded and move up. takes days to find good temps /volts/speeds also load up games and run fraps to see in that games that u play if it makes a difference.
