ASUS P4B533 Mobo: Tweakign the BIOS for MAXIMUM performance.. What R your settings?

[WayneTeK]

Ok

I just made a new system and i don't OC that much...

I want to OC my new 1.8A P4 but i don't know what to change in the BIOS settings... I don't want to damage my system to accidently leaving it at a 1.7voltage core or something to that nature...

So if anybody has this particular MOBO or has any recommendations, could ya please help out?
What are your settings like for OC???

System Specs are listed in my signature.

Thanks!

I have an Asus P4T-E mobo, so I may be able to help.

From what I've read, and experienced, the P4 1.8A is GREAT for OC'ing. But, doesnt this CPU have a locked multiplier of 18x? How can that be run on a 533MHz FSB? 18 x 133 = ~2.4GHz So wouldn't the mobo automatically OC this CPU by default? Someone, please help out my n00bn355.

Anyways, I can stabley (word?) run mine at 2.34GHz with my current cooling solutions and no hacked bios or voltage mods. It's really easy to OC it. Go into your BIOS setup and enter the advanced screen. (At least, this is where it is in mine.) In there you should see settings for your FSB. Since my FSB is 400MHz, it's default at 100MHz but allows me to set it up to 133MHz (533MHz.) I don't know what your board has for settings, but I believe it should have an FSB setting ranging from 133MHz to 150MHz, if not higher. Just ease up from 133MHz one step at a time, boot up, and run SiSandra or another CPU intesive program. If this runs fine, crank it up another notch. If you find a point where it locks up, increase the voltage in small increments to give it more juice. Keep repeating this process until you can no longer. I have had my system running with 1.65v for extended periods of time with no problems. Of course, every machine is different. If you're skittish, research cooling options. Although, I do notice you have an aluminum case, which is a very good thing. I have a Lian-Li myself.

I have RDRAM, so I don't know what (if anything) you'd have to do about your memory. I say this since with Rhambus, you change the clock multiplier from 4x to 3x so as to not over-tax the memory and crash the system.

Can't answer the question - but welcome to AT and "stably" (not stabley) is a word.

I've got a P4B533-E which is exactly the same as P4B533 bioswise (the only difference between the versions is the raid-controller). Use a 1.6A @ 2.64 with ddr433 ram (via a hack setting some jumpers you can run the ram asynchroneus from the cpu)

The P4B533 can go from 100fsb (which you are on now) in 1Mhz incrementsjust raise it like DLWebmaestro said. Do it in small increments, but as most new 1.8As do at least 2.4 you might as well try setting it to 133 from the beginning and see it won't work right away. Then raise/lower it until it's unstable/stable. Then you can raise the voltage to make it stable, then up the fsb again etc. Just keep below 1.7v and you shouldn't have any problems.

EDIT: Oh, and this thread belong CPUs and OC'ing, there you'll find many people with the same board who'll help you
