pls help oc phenom 2 x4 955 on mobo 990xa ud3

i have the follow
mobo : Gigabyte 990xa ud3
ram : 6gb
cpu : phenom 2 x4 955
cooler : cooler master evo 212
the normal room temp is about 35 c
i oc it from 3.2 to 3.8 and raised the voltage from 1.404 to 1.429 and the max tem goes from 58 to 65 c when i reach the 3.8 but what makes me afraid is that my NB temp is 67 c
should i return to 3.6 or there is something i can do or that is normal and i can go for the 4.0 GHZ

  1. That is getting pretty hot, and your room temp ( 35 c???) is very high. I suggest backing off the cpu freq. and voltage, and just getting the northbridge to 2600 ish. Takes a fair bit less voltage, so less heat, and still makes quite a bit of difference in performance.
    Or go to something like a H100i watercooler on the cpu, but imo that is not worth the cost for the gains you will get.

    I would try to keep normal cpu operating temps below 55 C. Closer to 50 C is better for long chip life.

    thank you for your replay ,, if i raised the nb to 2600 that will make litle temp ? and yes that is my room temp i am in the middle east "africa" :)

    You might not be able to get to 2600 NB, it depends on the individual chip. Even 2400 will add a fair bit of performance though, and probably take very little extra voltage. So no, it will run at pretty much normal temps for you.
    This assumes you do not overclock the cpu itself, or overclock it very little.

    I would advise asking assistance in the AMD overclocking forums, and doing things one small step at a time.
    I back my 975 off from 4.1 to 3.9 in the summer, , my room temps are 25 ish C in the summer here.
    But I leave the northbridge at 2600 all the time.

    Do not use overclocking software to do this, read up to learn how to do it manually in the bios. And be very sure of what you are going to do before you do it. You will get better results this way, it just takes longer.

    Link to Tom's AMD overclocking thread. Good luck!

    *edit. Raising the NB will speed up the HT link. Letting it get too high causes problems.
    See above linked thread, read as many Phenom 2 OC guides as you can find before going too far with this.
