A little help OCing my rig

[chev19elle68]

Hey guys,
This is my first post here on your forums and im wondering if anybody can give me some pointers on how to tweak my system for some better performance. My rig is as follows:
P4 3.0 Prescott 478
Asus P4P800SE Mobo
2 dif kinds of mem - 1 Mushkin 512mb pc3200, 1 Corsair 512mb pc3200
550W PSU
Sapphire Radeon HD2600XT GDDR3 AGP

I'm pretty sure these are all of the vitals, I have air cooling and a pretty decent flow in my case so cooling shouldn't be a huge limiting factor. If anybody has some advice as far as values I should try out in my BIOS that would be greatly appreciated. I haven't dabbled much in OCing before, so this should be pretty interesting. The computer is used mainly for gaming with a lot of multi-tasking.

Any help would be greatly appreciated, thank you!

i would start by locking your agp/pci bus to 66/33

after that i would slowly bump up the fsb and then test until you hit a wall at which time you can slightly bump voltage. after that you can do some other things but I will let someone else chime in since I'm not the most experienced person here by far.

Alright I will try that out. I read bumping it by 5 at a time is recommended so i'll try that when I get back from work. Once I do hit that wall, which voltages should I play with? The VCore, or others? Thank you Ian for posting!

any progress?

also once you hit a wall you can try a few things...not neccessarily all at once...bump up vcore, raise ram voltage, and sometimes slightly bumping up agp volts can stablize things.

Yeah, I got my FSB up to 215 before it started to become unstable. I think I shouldn't have fiddled with my setup though. In conjunction with overclocking my processor I used the application RivaTuner to overclock my new video card, and now my screen is sort of shaking. It's not too bad while on the internet or in word processing, but when I play video games (which is most of the time) It has started to shake pretty bad. I have reverted all of my settings back to their original preset values, however the shake is still there. I wouldn't think just adjusting some settings would result in this so I dont know what happened. Thank you for the replies Ian, once I get this screen shake figured out I think I might start back up on my overclocking.

lol... I had that happen with my old x800 when I overclocked it.

I put everything back to normal, and after a reboot it was fine.
