More volts; 4.1ghz.
Make sure your temps are all right. I got mine to 4.3 on a good motherboard, and its stock is like 2.8. Your stock speed being higher, and temps lower you should get a good OC well above 4ghz. My P4 took 94C when I was testing out effects of no thermal paste, and toothpaste, without throttling.

My 3.0C can hit 3.7 GHz with a memory divider but each CPU is different.
You can go to 1.6 volts or a little over but beware of SNDS. (Sudden Northwood Death Syndrome) You can destroy your processor at 1.7 and getting close to that is not recommended.
If you add volts keep a sharp eye on your temps and don't go over 70 deg C
If you are crashing at 3.6 it could be the top end of the processor or your memory could be holding you back if you are running it at the same FSB as the CPU. To test the CPU alone, set the RAM ratio to 5:4 and test at 3.6 again.
NvidiaOCmaster: Are you sure that was a Northwood and not a prescott? I have never seen a 2.8 get to 4 GHz. I think slower is better for a beginner like the OP and 94 deg is certainly not good for your processor or mobo.

idk anything about northwoods, but I would say 1.55 to be safe, but wait to see what fabulouscoops has to say.

i getting real confused now guys as it seems i getting told different things lol
i would be real happy if i was to get my cpu to 4ghz, but is that just wanting to much? and if it is possable would i just have to up the volts to 1.6250 (maybe 1.6500) and change the fsb?
if my ram is the problem and im guessing its not as it was preformance ram when i got it then i could just slow it down like said yeah.

Its as close to 1.7 as you want to risk. Here is some background.

I run mine 24/7 at 1.6 volts.

k to be safe i think i will go no more then 1.6 volts. roughly what would you guess be the max fsb that would work at that volt or is it just the case of keep trying. also if i find one that wont post, is that the end or would there be others slightly higher?

You just have to find the best spot for your particular CPU, motherboard and memory. Each one is different. The multi is 15 on your processor and I'd say the ballpark ceiling is about 250 FSB (3.75 GHz). If you don't get a stable OC then back off 5 MHz and try again. If you start to feel comfortable and want to push the envelope, try upping the voltage a notch.
Its all trial and error.

Just a quick message from a friends pc..
Going on what was recomended i managed to get my system to run at 4.2Ghz!! Didnt have time to run Orthos prime to check stability as lunch was ready so was going to do that later... only while having lunch my fire alarm sounded of... my room had a horrable smell and a popping sound.
i have killed my pc
nah only kidding
thanks for all your help guys but i think i gone as far as i dare go... cos i cant afford to replace my cpu
I have managed to get it to 3.45Ghz so thats a 450Mhz gain.
anything above 230mhz fsb seemed to crash with a 1.6volts (dont want to rase it any more due to SNDS)
dont know how stable i am at the moment but all seems to be ok. will run Orthos prime tomorrow if i can while at work to see how stable it is.

thnx
i must confess tho that alough i know nothing about overclocking ect i know plenty about computer hardware as have build many computers both for personal use and for my job (used to build computers for BBC - big tv company in england)
my biggest worrie with overclocking was how much was to much and not wanting to fry my cpu.
ill run the test tomorow while at work to see if its still stable when i return.
only thing that does worrie me is my cpu heat is up to 52C and i have not been doing to much, only downloading/playing mp3's... would this be classed as normal for a overclocked pc?

Very nice 15% OC.
52 deg is not too bad for light load with a P4. I think you have a good chip and good memory. Have fun with it.
