Tried more vcore? Could also be your board doesn't have AGP/PCI locks.

Could be either of Yiffy's suggestions, and possibly the RAM that's limiting you, as well. If you could post CPU-Z screenies (of CPU and RAM tabs) and let us know what RAM you have, that would be helpful.

Do you know what timings the RAM is rated for? I don't think it will make a difference, as you are not yet even running at the RAM's rated speed, but it wouldn't hurt to change CAS Latency from 2.5 to 3, just as a tester. All in all, that's not a bad initial overclock on a Williamette. The most my old 1.6 ever did was 2010 mhz...and then it died.

You might want to try some more vcore, if you can adjust it. Stock vcore should be 1.75, so you should be safe up to 1.85v. Also, do you have a PCI/AGP lock? If you don't, then I would say this is most likely going to be the ultimate limiter, regardless of what else you do.

alrighty thanks for all the help, i shall try upping the vcore. where can i go from here if i do have a PCI/AGP lock?

After locking PCI/AGP, the aforementioned tweaking of RAM timings and vcore adjustments would be your next steps.

awesome. this is my first ever OC so if i cant go any further im happy with the results.

no sign of being able to lock it... but i can change the frequencies, same with DDR reference voltage and AGP VDDQ voltage.
which freq. for AGP/PCI:
66.66/33.33
72.73/36.36
80.00/40.00
?

You want 66.66/33.33. Im pretty sure it should be default

Especially on a willamette core, those things are just blah for overclocking. I got my 1.8 willamette to 2.25GHz, but it was a little unstable because my board didn't have AGP/PCI locks.

lol sry if this sounds noobish but could he not raise his fsb to 200 and lower his multi for the same clock speed and a better FSB? *this is assuming both his mobo and RAM support 200FSB would this cause issues? just wonderin...

Intel processors have the multipliers locked, can't change them.

my "512mb" is 2 x256.. and only one of them is rated at 200Mhz, i think the others only 166.

Ahh ic, are they unlockable like some AMD procs? or are they like my da*n sempron *glares at it* and its not unlockable.

Ahh ic, this would hold you down then, but you could still go for that instead of 125. but after hearing about the multi lock then maybe not... I do amd, not intel

I have never seen nor heard of anyone successfuly fully unlocking a P4. You can buy engineering smplaes off ebay sometimes that are fully unlocked though. On the new Prescott cores, some motherboard makes have exploited a flaw in the CPU identifcation bit that allows the use to select either a x14 multiplier or the stock multiplier, but that's it.
