im building a new rig and i never overclocked before. i was wondering if i could get some help please.

from what settings in bios needs to be changed and to how much recommended .
voltages
speeds what ever needs to be changed

i will be reading as much as possible on other threads but would like some detail help

With that CPU, its as easy as changing the CPU multiplier in BIOS. For a more complete tutorial, look under toms CPU articles and there is a primer there for AMD cpu overclocking.

for small overclocks you will not likely need to change voltage but the more you push the cpu the more voltage it is going to need. so if you are planing on getting to 3.6 plus you are going to need to give it some extra voltage. get it to enter windows and then run a program like prime 95 to stress the cpu to make sure it is stable. if it crashes then you will want to slowly increase voltage. do this til you are happy with the speed you are going and the lowest voltage that keeps the cpu from crashing under stress

You'll only need to change the voltage if you plan to OC anymore than 5-10% I'm not sure what the 955 is good for, but I'm running my 965 3400Mhz @ 3800 Mhz without any voltage change. I just upped the multiplier to x19. Your motherboard will have the OC settings in the first option in the menu... M.I.B or something like that. You'll see where you can change the multipler/FSB... Multiplier x FSB = CPU Frequency... So simply up your multiplier a little for a free overclock with no voltage changes and probably almost no difference in heat. I got such little change in heat it was rediculous. Great CPU's.


Don't go changing voltages until you're more comfortable. I'd ditch that video card and go with an Ati 5xxx series though if you still can :) 

ya it all depends on how lucky you got on your cpu some will overclock no problem with little to no voltage while other with not like to go anywhere with out increasing voltage so you just have to play with your cpu until you find out what it likes.

could someone give me a guide line like where to look at in the bios to change the multiplier. i really wanna try this. i know how to build pc's but i was never willing to over clock before so i never tried. id really appreccieate a detailed guideline. i saw the performance increases over clocking to 3.8 and that where i would like to be.
and to buzznut could u gimme that link to the reference u were looking at.

Well remember when you change your multiplier you're changing your CPU frequency (clock speed) but when you change your FSB, you're changing everything including memory speed. I'd stick with the multiplier until you do more research on overclocking memory, etc. before you change anything else.


Once you finally up your multiplier to a point where you can't pass stress tests like Prime95 (or even boot Windows for that matter), you'll have to up your voltage to overclock anymore past that. Raising your voltage however is when you start to experience more heat and potential consequences.


If you overclock to the default voltage max, you really have nothing to worry about in terms of CPU degradation or life-span issues.

Overclocking ram comes down to being a shear enthusiast.. In most cases you won't notice a performance difference like you will with the CPU, say frames per second in gaming for example. You can run benchmarks like Sandra or Everest and see the improvement but you won't really feel it.

You shouldn't OC your RAM unless it's ready to do so (has a heatspreader, etc.) Your RAM can be overclocked some, I have G.Skill too. But you can't OC it like you can a CPU, you have to change timings, etc. etc.

Sometimes you can get better performance by underclocking your ram and tightening the timings. I actually get the best performance with my 1600Mhz G.Skill by running it at 1400 with 7-7-7-20. I can't keep it stable though, so I have to play with it to get it tweaked out. I'm just running default 1600 9-9-9-24 though because there's not a lot of point in it. G.Skill is cheap too, so there's not much you can do timing-wise.


I wouldn't worry about OC'ing the RAM bro.

sometimes to get that last little bit of umph out of your cpu you can play with the fsb speeds but keep in mind this will effect the speeds of your ram as well so the system might crash if you push the ram to far

i see
so fsb affect the ram speed, frequency speed of the cpu, hyper transport and northbridge. since they all are connected. do those have voltage changes also if i decide to over cloock the fsb
