how do i overclock my GPU and CPU....???

Question

GPU = nVIDIA 7900GTX 512MB 256bit GDDR3 650mHz eng clock 800mHz mem clock 400mHz RAMDAC
CPU = AMD Athlon 64 x2 Dual Core 6000+ (3.0 gHz) 2000mHz HT speed FSB 2x 1MB cache 125w power consum
MB = ASUS A8M2N-LA
*my cooling may be insufficient for max OCing, but i got a 630w power supply and sev fans. input please if you got the knowledge and dont mind sharing it :) ty

added detail based on 1st few answers: many of my fellow gamers OC their CPUs and GPUs, getting 10-20% more out of them without reducing the life of the processing units. its not that my sys specs are lacking now, but i want to be able to run next years games with the graphics settings turned up high while not losing performance, heh.

Answer 1

For processor overclocking, read this:

For GPU, try Ntune, VDO Tool and would you believe, ATI Tool.

For coolers, best would be the Thermalright Ultra 120. If space is tight, get the Ultra 90. Also consider the coolers from Scythe.

Overclocking is great for the lower Ghz chips. Usually you can play around with a large headroom. In the case of that X2 6000+, its 3.0Ghz default speed is pretty close to the max.

Answer 2

If you don't know how to do it, I suggest you don't attempt to. I will go so far as to say it is generally done in the computer BIOS. You can go two routes:
1) Increase the CPU clock multiplier. This is the most common way to overclock, as the CPU clock speed is Front-Side-Bus (FSB) times the clock multiplier.
2) Lower the CPU multiplier and max out the FSB. This is the most dangerous way to overclock, and is the diehard overclockers method. You really need a top of the line board (and CPU) to go this route.

Answer 3

the only issues you "constantly" start up with is disabling CPU unfold spectrum and disabling PCIE unfold spectrum. additionally set PCIE to 100mhz manually (not vehicle). those are secure and cautioned for any equipment. in many situations I up FSB first and dial interior the utmost velocity my ram can look after and be rigidity examined. I manually set RAM timings yet I basically use extra constructive high quality ram and that i'm positive with the manufacturers timings. Then I up CPU multiplier and rigidity attempt that. If i'm not getting comparable speeds to what others are on that particular CPU/RAM i glance into the ins and outs like voltages, LLC, C states, APM, HPC, and so on. lots is particular on your BIOS and good factors there. basically touch voltages in case you will desire to and easily as low as you will desire to. heavily however i'd save in mind each and every little putting you have available on your BIOS and interpreting up on them and precisely what they do. as quickly as you recognize what all the little issues mean you will understand what to show off or on, how secure that's, and if that's even going to make a distinction.

Answer 4

I suggest don't over clock, it will reduce ur PC's life + u don't need to over clock anyway.
optimize ur pc, that is what u need.
anyway, there are softwares available, like Rivatuner etc to over clock

Answer 5

Not a good idea ! You will sooner or later burn out your CPU.

Answer 6

Why would you need to? That system is good enough already.
