Increase your HTT (default 200). HTT * CPU multiplier gets you core frequency. So like if you left it at 15 multiplier and upped your HTT to 250, 250 * 15 would land you at 3.75ghz (just an example, you probably can't set it that high). As you increase the speed of your processor, you will probably need to increase the CPU voltage.

Now, a few other things rely on the HTT clock. As you increase it, your NB frequency, HT Link frequency, and RAM frequency will increase. All of these work on multipliers, so just try to keep your RAM close to stock frequency, keep your HT Link close to 2000mhz, and keep your NB frequency between 2000mhz and 2400mhz to start out.

i dont understand what u are saying. plz simplify your explanation.
post #4 of 6
I have the same CPU.

CPU Ratio: 15x
FSB Frequency: 250
NB Frequency: 10x
HTT Link: Auto
Drop your RAM Multiplier down so your RAM speed is less than it's supposed to be.*
CPU Voltage: 1.4

*My stock RAM is 1333MHz. I dropped the multiplier from 6.66 to 5.33 (250 * 5.33 = 1332MHz).
