Overclocking advice needed.

My current build is a Pentium 4 2.4 Ghz Northwood (stock cooling), 512mb Samsung DDR333, MSI SiS645DX mobo with ATI Radeon 9000 Graphics. I want to practice overclocking my CPU before i try it on a new computer i plan to buy but i've run into a few problems. Speedfan is listing my cpu and chipset temps as temp1 and temp2 and i don't know which is which. Idle/Load Temp 1 : 41/48 Temp 2 50/65. Before I begin overclocking my system I was wondering what are safe temps for my Mobo and CPU. Thanks!

Update 1:

I am now running at 2.8Ghz, FSB 155.7, 1.5V with the case open getting Idle Tems for CPU/NB 33/37. Having some major issues trying to run stress tests though. SuperPI pops up an error saying SQR NOT CONVERGENT and an assortment of other errors within 5 seconds and Orthos runs into a fatal error when I start the test. Any ideas how to fix?

Update 2:
Using WinRAR to compress huge files my system crashed. VCore is up to 1.575

You need good case fans and decent memory. The 533 2.4 wasn't a great overclocker; the 800 2.4 could easily run at 3.0-3.2. I had random reboots with my msi board, so if you want maximum stability, I no longer recommend overclocking to anyone. I gave it up when I switched to socket 939. Temperature wise, 58c under load is a good limit.

Your 2.4B should easily do 2.8 Ghz, but your RAM will be holding your overclock back. As far as SpeedFan goes, temp 1 is your processor, and temp 2 is your northbridge chipset. Since your motherboard doesn't have a fan on the northbridge heatsink, you'd need to attach a 40mm fan to it, before trying to overclock; 65C is awfully hot for a chipset.

northwood is the best P4 ever made ;)

My 2.8Ghz northwood runs at 3.6Ghz on ninja cooler. Just make sure your mob and ram are decent quality. Increase the FSB slowly and then increase the power to cpu if needed.

Also get a Tuniq Tower 120 or some good cooler like.

Correction:

Also get a Tuniq Tower 120 or some god-like cooler.

:D

Yea i tried overclocking it a little last night I'm at 2.5Ghz but the system runs very very hot. The NB is at 68 degrees after half an hour on SuperPI... Looks like im going to need some cooling before i can go any further. The RAM is actually DDR333 not DDR266 like originally posted. Maybe ill leave my case open to get some lower tems...

leaving the side cover off of the case will not help with cooling the parts that need cooling down. add a fan or two to help pull the heat out of the case and get a better cpu cooler.

I'm thinking of opening up the side of the case and blowing a normal home fan into it and try to hit some better clocks without ramping my NB much higher than 65 degrees. I really dont wanna spend money on such an old coputer. Will this work or should I just give up trying to overclock this thing because the NB runs so damn hot.

CPU Tems are okay but NB is is running extremely hot this should help the NB rite.

you'd have to put a new heatsink on the northbridge, or see if you can't rig a bigger fan onto the heatsink. other than that, you'd have to back off on the fsb to get the temps down, which would mean a lower overclock.

that's all i can think to lower those temps. afaik sis boards aren't known for their overclocking prowess, make sure nothing else is being overclocked (pci bus, sata ports [i dunno], etc), that could possibly stress the northbridge, causing unnecessary heat.

Taking the side off the case will help, IF your case had bad airflow to begin with. It'll lower ambient temperatures. The easiest way to cool your northbridge would be to just get a small super cheap heat sink and paste it on there. Never fails.

From what you guys are saying looks like i might have to spend a lil to overclock this thing anywhere.

What do you guys think of this monster. It should fit because my graphics card isn't that big. Right now the heatsink on the NB on my SiS645DX is less than 1cm high with no fins or pins rising out of it. Any estimates on termperature change for load tems if i install this one. Case airflow is not very good.

All you need is to superglue a 40mm fan to your northbridge heatsink. You've got exactly the same NB heatsink that my Socket 754 MSI motherboard had: pic, and my temps dropped 20°C after mounting a 40mm fan on it: screenshot. That's at idle, but it never made it to 40°C, even while overclocked.
