kruni, it was clear to me from the first post that you have just jumped up with the OC "no limts".
first thing first - what do you want with your PC? If "office", you don't need OC, if gaming - in all honesty, you have a p45 mobo and a
P4 
, so despite economic crisis my first advise is go buy a C2D or a C2Q. build a more balanced pc. and what's your vga?
second, guys, don't jump on kruni at this time, although he deserves criticism. I can understand if he read abut incredible overclocks with INTELs. hence, the thing he might not have realised is the difference between capacities of different CPUs to overclock. Kruni - here are some examples:
- my (allendale) C2D e4300, has a stock speed of 1,8GHz and it OCs very easliy and very high and temps are just a few degrees higher, although the temps are high as such, probably as hot as a P4. Very easy overclocker, no voltage addition.
- my old (sckt478) p4@2,8ghz is basically a typewriter now - I OC'd it from 2,8 to 3Ghz and can go higher without voltage increase, but didn't need to and heat is a bit of a concern with this one, as well as its one core efficiency.
So keep in mind there are spectacular results, but there is also difference between the CPUs, but the approach is the same -
daft is right, only +5FSB increase for starters, then test.
Now, if you didn't, install CPU-Z to check your processor OC and Memory information (frequency, timings) and other temperature monitoring software. Read their data before you OC. In CPU-Z read the first page and then Memory tab, write them down.
Finally, I guess I shouldn't ask you if you have done the previous OC through BIOS, that's right, isn't it? Get BIOS to initial settings, clear CMOS. That'll bring you back to 2,94GHz. Now, you already know that CTRL+F1 will unlock all the features in Gigabyte BIOS.
Anyway, I'll repeat - enter in BIOS the MB Intelligent Tweaker:
a) Now shadow7037 is right about memory (kruni how much ram do you have, just out of curiosity?) - anyway, kruni, Memory frequency will also go up when you OC your processor - raising the FSB will raise the memory speed as well - so from the very start see what memory frequency you have at the beginning of OC (I guess 800). now enter the System Memory Multiplier on the MB IT of BIOS and change it so that you have a lower memory frequency. as soon as you apply (press enter) a lower multiplier the BIOS will show you the future speed of your memory (on the same MBI page), just be sure its lower than 800.
b) Enable CPU Host Clock Control. In CPU Host Frequency type 138, press Enter.
c) Now boot, you should have 3.036Ghz without any voltage increase. Now install and run Orthos or OCCT. See if it works without overheating and failures. Report back.
----------------
I suggested you to upgrade if you want gaming - just to give you an idea of how good the new processors are OCing. The C2D allendales, conroes [series e2xxx, e4xxx, e6xxx] or even better - newer C2D wolfdales [series e5xxx, e7xxx and e8xxx] - OC like hell. My older allendale e4300 went up from 1,8GHz to 2,88GHz without raising the voltage, just adjusting the memory multiplier. That's 60% overclock so that's why kruni may have been expecting soemthing not less spectacular, guys. Temperature is a few degrees higher than at stock. however, allendales are hot, basically as hot as a pentium4. Wolfdales seem to be much better. Kruni, even with such a remarkable overclockability I did not dare to push my e4300 to 2,4GHz at once - instead I first increased to 2GHz and then tested, 2,2GHz tested, etc.
