I am new to overlocking and would like to take part in it. I bought this MOBO for a reason. I don't know the specific timings and latency's etc. to overclock.
MY INFO:
Mobo: XFX 790i Ultra sli (i have latest bios)
CPU: E8400 (dual core 3.0 Ghz)
Graphics card: XFX 9600 GT
Ram: OCZ XTC Special Ops Edition OCZ3SOE13332G (not the best but i hope it will do. I will also be willing to upgrade my ram)
OS: XP Professional 32-bit
is there any more info you need to know just ask i will get it. Thank you hope we can figure out how to OC my board THANKS  |

i do have an after market cooler. ARCTIC COOLING Freezer 7 Pro 92mm
I have read a little amount into OC'ing, even about my MOBO, but i found that pretty much nobody runs my RAM. So i don't want to go and try it and have everything crash

Its just trial and error.
If you set the memory to default speed so it is not linked to your cpu you can consentrate on just overclocking you processor.
You will need to get app's to monitor temps, actual cpu speed etc....

If you motherboard has a good BIOS for overclocking, you should be able to overclock the CPU, but not the memory.
That's why you should read Aaron's artical.
Edit:
Too Slow.

Ok, i will try unlinking it. do i have to adjust anything else on the ram, like the timings. right now i'm at: 7-7-7-20-1T
What are good increments to adjust the FSB by? | |

You don't need to mess with your timings yet, if you adjust one thing at a time it will make it much easier to realise what caused the problem.
I would to begin with raise it to say 3.5Ghz, then bump up the fsb by 10 or so till it fails to boot, then raise your v-core a little (less v-core the cooler your chip will be), don't go over 1.45v I personaly would'nt go over 1.4v. Once you have raised voltage a little check your temps, and run Prime95 to check your temp's at full load. You can leave it running to make sure the overclock is stable if not it will report error's.

Errr... 45nm cores you want to keep under 1.3625. 
That's the max intel recommends... | |

But then again companies always under specify such things. Its like expiry dates on food. One or two days or even one or two months (for things like canned foods) over the date is usually safe.

Keep it under 1.3625v? My E8600 is currently sitting at 1.4375vcore. lol
A couple helpful things to know when overclocking an E8x00 CPU are the VID and Stepping (Revision in CPUz).
The VID is your CPU's default voltage and CoreTemp can tell you what it is. These chips are rated within a range and different CPUs have different VID - some lower, some higher. Some motherboards increase the vcore automatically when you overclock if the setting is left on Auto. Because of that, it is best to manually set the vcore to your CPU's VID in BIOS.
There are two Steppings for the E8400, C0 and E0. C0 is the original and usually those revisions need higher vcore & run warmer than an equally overclocked E0 revision.
As you can see, my E8600 is an E0 and the VID is 1.2125v.
