P4 1.6A quick question..

Hi,

I am relatively new to overclocking, so forgive the newbie nature of this question:

I just bought a P4 1.6A running on an Epox 4T2A3 (i850 chipset) using 256mb of PC800 RDRAM.. Geforce2 video, etc...

I'm not totally sure I want to overclock since the performance seems ok, but I was just curious if you could provide a quick step-by-step on how to overclock. I used to have a Tbird 850 so because of the unlocking issue, I never bothered to overclock it, but I understand that P4s are pretty easy to speed up. Can anyone give me any pointers?

Thanks.

It looks like all my voltage and bus speeds are controlled by either BIOS or dip-switch.. is there any physical modification I need to make to the P4 before I can overclock?

no, just start bumping up the front side bus speed. when you hit a speed that is unstable, slowly up the voltage until it gets stable or your temps get too high. generally, a little extra voltage will get you a couple hundred more mHz.

I have a ASUS P4T-E with Rambus. You do overclock through the FSB but be aware that Rambus is very sensitive to overclocking. I can get my P4N 2.2GHz to a 2.6+ @ 120 MHZ FSB with the core @ 1.65 v. without a prob. But remember when you overclock, heat is generated so be aware! If you can, get a better heatsink and fan as I did. Just to let you know, It cranks when done right! My Rigs
 
i don' t have rdram like you and i don't have the epox board. but i do have 1.6a and asus p4b266 board. i'm relatively new to oc'ing as well and i did hours of research before i oc'ed, but i found it to be relatively easy and not dangerous as long as you keep it modest.

first, you have to get into the bios and look for the fsb. your computer speed is comprised of fsb*cpu multiplier. the multiplier is not changeable and is set at 1.6 for your 1.6a chip. then your default fsb is 100, which shows 1.6*100 = 1600 mhz. so to oc your comp, simply raise your fsb a little by little.

second, if you're computer is not loading say past fsb = 133 but boots fine at 132, then at fsb = 133, raise your vcore one notch until your cpu boots up fine.

that's it. i could tell you about oc'ing your ram and stuff too, but i don't have your board, so i'm of no use there. hope this helps...
