Hey guys I am wondering if any of you could give me advice on over clocking my AMD Athlon II X4 635 processor. Here are my specs as follows.

CPU:AMD Athlon II X4 635 @ base clock 2.9 ghz. (have gotten it to 3.6ghz on my own but it aint stable.)

Motherboard:Gigabyte GA-78LMT-USB 3.0 (has a 760g chipset)

RAM:6 gb of 1333mhz ram

GFX: GT 610 2gb.

I have been overcocking before by only modifying the Clock ratio thingy and usually have it set at 235 for a stable 3.4ghz. my temps are in the 20's with a CM gemin S524.
any help would be appreciated. this isn't a black edition so i can't modify the multiplier. The stock voltage is 1.2v

Aiming for 3.7 ghz. I want to play watchdogs on low settings with a gtx 660 i am ordering and need to make sure my cpu is ready which it aint.

Learn the secret Gigabyte handshake to expand menu options. If you do not know what this is, read the BIOS section of your motherboard manual.

The sweet spot in the system clock for DDR3 1333 is 250MHz. If you drop your memory setting from 6(.)67 to 5(.)33 your memory will be running spec speed. Your HT Link multiplier should be 8x (or, 1600MHz). Set your IMC/NB multiplier to 9x.

The system clock at 256MHz will slightly OC your RAMs to 1365MHz -- if they cannot take it you will have to loosen the timings.

256MHz X 14.5 = 3.71GHz

If the temperature is fine but it is unstable at a higher clock speed then you should increase the voltage until it doesn't crash. You want the lowest possible stable voltage. I hope you're using an aftermarket cooler for this.

when i change the ram to 5.33 it says 1066mhz not 250mhz, and the main system clock according to the bios is 200 mhz.
