p3v4x no post > 135FSB. Help!

begood · 4th November 2002, 4:30 PM

Hi there fellow enthusiasts. I know the P3V4X is one of the greatest p3 boards around.

Here's the system lowdown.
1) P3 600(100fsb) Slot 1.
2) GlobalWin V0S32 Cooler (Very efficient cooling)
3) Antec TruePower 380 PSU
4) Asus GeForce4 MX460
5) 1 x 256mb: Tonicom PC166 (CL2) SDRAM
6) 1 x 256mb: Corsair XMS150 (CL2) SDRAM

The machine can't seem to POST if I set it above 135 Mhz FSB or/and it makes strange sounding bios beeps.

I'm starting to think it's a motherboard problem because I can't figure out what the problem might be. Cool it be something wrong with the CPU? Have I reached the overclocking limits of the CPU???

The RAM has high potential for overclocking, there's enough power from the PSU, there's enough cooling from the CPU cooler.

Help muchly appreciated. Cheers!

If your slot one P3 is a Katmai core (cant remember when they changed to coppermine) then it might be that the off die cache is not very happy at that speed, i could be wrong though.
Have you tried going to the asus site and finding the manual for your board and read up on what the bios error message beeps are all about? and what the different ones mean?

http://www.asus.com

Or if you have the users manual then i reckon perhaps reading it would really help your plight

The P3V4X doesn't much like two different brands of RAM. That could be a problem. Try running the RAM timings 'By Spd' then see if you can overclock further since both sticks should hit 150Mhz+ at default timings.

If it is any consolation, my ASUS A7V133 refuses to run stable with any FSB overclocking whatsoever.

Has nothing to do with the CPU either as I can reduce the multiplier and its still an unstable piece of crap.

You could also perhaps try pulling 1 RAM module out, and see if it works with just the one (or the other). Just another option to try.

Have a P3V4X at work which has run like a charm for three years. It has a PIII 733 (fsb 133) in a slotket in the slot. Went up to work and tried an overclock with the old Legend RAM in it (256 Mb).

The bastard wouldn't even overclock to 135 without booting into BIOS and a nasty message about BIOS detecting a wrong FSB speed and please set it back or I'll .....

Go figure...

So I set it back to 133 and all is happy and well again.

I think boosting the FSB from 100 to 133 is a bit hopefull for a slot 1. Try backing off a little.

stick a heatsink on the clock generator!
this was an old tweak from back in the day

the clockgen on the p3v4x can get quite hot, and putting a heatsink on it helped a lot of people get past 133mhz fsb.

I have come to the conclusion that the CPU is pretty much maxed out. But some lucky folks are able to do higher with the same CPU and board. Cheers!
