Listen please, I have an AOpen AX4SPE-UN Motherboard wich let me change the latencies of the memory it's voltage and frecuency, and the FSB speed, that's why I think this is enough for overclocking. Well I have on it a 2.8C P4 CPU, 2 x 256Mb of Corsair CMX256A-3200C2 memories (wich says it runs at 400Mhz and 2.3.3.6.T1 of latency times), a HIS Excalibur Radeon 9600 Pro video card, an Audigy sound card, 2 x 80Gb Maxtor ATA100 HDD, and so on.
Well my problem is that I don't know how exactly to overclock my system, and I want someone to show me how to do it without breaking it.

Please Help me, I'm interested on the overclocking world!!! :eh?:
 
You have a great setup. The ony question is if you have/and are able to find the settings to adjust CPU FSB. Those 2.8C's usually do at least 3.2Ghz on stock Voltage but you will be pushing your RAM too far so you'll need to start testing with the RAM ratio at 5:4 (or 320Mhz) Look for these settings in your board's manual, take your time and do a lot of reading up in these forums. That's how we all learned!
 
On intel, upping the FSB is the (only) way to go. As lancelot said, make sure your RAM can keep the pace by having it run slower with different dividers (5:4 or 3:2 rather then 1:1). Those timings are great, keep them!

Keep an eye on temps (using Motherboard Monitor for example), and up the voltage if neccesary. Load temps of <65 degrees centigrade are advisable for Intel.
 
Thanks a lot for the help, but I wonder if changing the voltage of the RAM to 2.7 is safetly...!

Seen some guys running 3.6v for ddr600 :santa: till 3.2 should be fine with some airflow over it
 
Thanks again and pardon my ignorance but I'm new on this. What is exactly the meaning of this terms: (5:4, 3:2, 1:1, ect)
 
If you run 1:1, which is most common, the ram runs as fast as the FSB.

Usually, the FSB can be increased more then the RAM speed (eg, the rams maximum is lower), so you would want to run the ram slower then the FSB, to reach a higher speed in total.

If you have ram that will run 200Mhz, but a CPu that can do 250Mhz FSB, you can use the divider 4:5, so that the ram runs 200 while the FSB runs 250.

2:3 same story.
 
Thanks a lot Sjaak and all the other people who help me!!! thanks again, I've learned something new.
