Can anyone explain tightening and losening up ram? I'm currently running Kingston Hyper X 1600MHz with 9,9,9,27 at 1.65v recommended timing and voltage. Also would it be faster to run 1300MHz with the CPU-Z recommended JDEC of 9,9,9,25 at 1.5v? Thanks for the advice....

"Tightening" means decreasing the timing numbers, giving more speed. "Loosening" is just the opposite. You would need a very good memory benchmark program to tell the difference between the two.

Your memory system will use about 20% more power at 1.65 volts than it will at 1.5 volts.

Got ya. Thanks for the info. One more question. If I'm running with a multiplier of 19 at 3.82Mhz and 1.296V. What should my FSB be running at? Its currently set at 2400MHZ. Im new to this so thanks for the advice.

Divide your clock speed(MHz) by your multiplier (3820/19=201MHz) will give you your FSB speed in MHz.

Or, download CPU-Z and it will tell you exactly.
