please someone give me a complete guide to overclock my processor (amd athlon 64 x2 4400+ 2.3 ghz)
my other cpu specs
2 gb ddr2 ram
ati 6670 1gb ddr5 graphic card
450 psu
msi pci expressed motherboard (MS-7373)
is overclocking safe for my cpu?

It is for the cpu..perhaps not on that motherboard, though.

so you are saying i can't overclock my cpu....

I don't know much about that motherboard. But if it is anything like my X2 3600+ overclock here is what you need to focus on:
1) FSB - front side bus
2) HTlink - hyper transport link
3) DRAM ratio (don't remember what it was actually called, but it basically takes your CPU speed and divides it by a number.)

First check your CPU temps under 100% load with PRIME95. Make sure the temps without OC are ok for the CPU.

Then get into the BIOS. Before you change anything look for those 3 settings listed above and write down their current settings. Then make sure the motherboard allows you to adjust each of them. If the mobo doesn't let you change all 3 of them you probably shouldn't even bother trying to OC because you'll hit stability issues with the ram or HTlink.

Change the HT link to 4:1. HT link works by multiplying the FSB by the ratio. so HTlink 5:1 will take the 200 FSB and multiply it by 5 = 1000. If you OC the FSB to 250 then the HT link needs to drop to 4:1, etc, etc. So drop the HTlink to 4:1 so you are not overclocking it. If you somehow push the FSB above 250 then drop the HTlink down to 3:1.

Next drop DRAM ratio. On my board the DRAM ratio was took the CPU speed and divided it by a number. It was like CPU/8. So at a speed of 3.2 ghz = 3200mhz the ram speed was 3200mhz/8 = 400mhz which is actually 800mhz for DDR2. Change the ratio to whatever it takes so that your ram is not OC'd above the rated specs.

Last lets look at the FSB. Your CPU has a multipler of 11.5. So take the FSB (200 x 11.5 = 2300 mhz = 2.3 ghz.) If you raise it to 250, for example, you will have a CPU running at 250*11.5 = 2.87 ghz. Start OC by raising the FSB in increments of 10. Don't go to far too fast.

I never hurt my CPU even in all my trials and errors, so I doubt you would either. But OC does raise the temp pretty substantially. I went from 1900mhz to 2600mhz and the temps probably went up by 20 C in the process. Pretty hot. I had it running at OC'd speed for almost 5 years before I upgraded.
