Hello, I want to know how to underclock a core 2 quad q6700 2.66Ghz to 2.13Ghz so that it will be just like my core 2 duo e6400 2.13Ghz, because the Core 2 quad is arriving soon, but Im not sure it will work due to my 275w psu and Im sure heat will be a problem, my motherboard model is Intel Q965/Q963 Express Chipset Familu. Please let me know if this is enough information and if Im underclocking too low.

Thanks For Any Help.

Im sorry I should have gave more information, I want to save power because im planning on putting a Core 2 quad q6700 AND R5 240, and im afraid that it will go over the 275w psu limit, I did insert my pc specs on a psu calculator online ( coolermaster.com/power-supply-calculator ) WITH the Core 2 quad q6700 and the R5 240 and it said the the psu reaches 276w wow 1 watt over is this ok... but when I decreased the ghz on the cpu from 2.66 to 2.13 the total load wattage was... 260w 15 watts below the limit so now at this point the load wattage is safe.

Now knowing this please tell me how to underclock OR let me know if the watts with the Core 2 quad q6700 and R5 240 in the optiplex 745 SFF are safe enough.

Thank You
