    Ok , im back with some results: after running the intel burn test ( it said that i completed it succesfully) i tryed tweaking VTT and PLL ( i set PLL to 1.6 - it doesnt boot) and with vtt ( cpu termination) 1.2 doesnt boot either ( i did the test with these set on auto ) ........the temp wasnt higher than 63....maybe need more tests or tweaks ?

    Your IBT core temperature results are in the normal range.
    Running IBT with threads = 2 (for your dual core processor) and memory = 2048 will probably raise temperatures another 5 - 7 C.
    I wonder what HWmonitor or Speedfan is reporting for your system voltages.

    It will be most helpful if your IBT screen-shot also includes the same windows that you used in post #6.

    Can you beg, borrow or steal another set of memory and a different psu to test with?

    Ok ill do the test again - with the programs required.....still cant tweak voltages ( it surprises me that some can easily achieve 450-550 with low voltages and i , for 450, have to raise the voltages sky high ) but ill run the test ......i cant use another memory stick because the computer case is sealed ( is in warranty , its only 10 months old )...

    This overclock that im interested in is for games ;i play some shooters ( fps games) online and i have read that theyre cpu dependent.....also some guys said that what should i be interrested in is to raise that FSB for the games ( they said this way it will send more "data") and that frequency is not so much important .......

    Here are some results (450x7 ) the rest of the settings are the same ( cpu termination and CPU PLL and all the rest are on AUTO - cant do nothing without putting them on auto;i tryed recommended voltages for PLL and termination but it wont boot....same with the ram voltage) ; the temp are even lower (this time the highest is 60 while last night was 63 ) ...the test is run with IBT on 2 threads but memory is 1024 (though i said ok when it asked for 2047) because it said i have OS on 32 bit and for 2048 i need OS on 64 bit .......it seems temp are not a problem for my pc but rather high voltage requirements to achieve some modifications......however i wont give up and im opened to any suggestions

    Mine is: lower CPU PLL to 1.6v or below, and see where you can get with it, before it's too late (it may be too late already).

    Thank you for the reply and for the patience .....i understood the danger of PLL voltages the first time you told me and also i set them lower ( to a stable config ) that time too ( i did the IBT test with that voltage but after that i restarted and changed back to a boot-able "standard")......anyway heres a new config i tryed ( dont worry i wont leave it on unless you all say its ok - i just made it to ask for an opinion ); i made some modifications ( 8 multiplier lowered the PLL and termination ; MCH core 1200 - default on bios says its 1100-and DRAM voltage 2.02) .....the config is stable (orthos and IBT included )....any ideas furthermore?

    Those look fine to me, if stable, save BIOS profile (press F11 in main BIOS screen) and you are good to experiment higher with FSB.
    Any special reason to set ICH/IO below default?
    Does the case hase a side intake fan, or anything special to cool the NB?

    Ok i saved the settings .......also ive experimented with 9.5x450 (4.27gb) in same other conditions ( voltages the same ram etc etc ) - it works! therefore IBT test ( threads 2 - i set it even on high ) and orthos ( 20 min ) stable - max temp 68 ( on IBT) and on orthos some random 62-61........regarding the ICH ( no special reason just .....random experiment- is it bad, should i change it? )......still cant reach 500 ( any ideas to tweak RAM?)

    Don't take it all the way to 500, 10 MHz FSB at a time I'd think.
    Loosen Static tRead, 11 or 12 till you reach max possible FSB, a bit more on DRAM Voltage up to 2.1v, and MCH Core 1.2-1.28v.
    CPU/MCH Clock Skews usually needed only at high FSB but you can try 50-100ps on each (8 combinations)
    I think ICH/IO is best left at default unless it needs tweaking. This is SB settings, not sure what exactly (MCH or peripheral side).

    Ok heres what i did : till 460-470 FSB it works (though not tested with IBTetc because i was sad of not reaching 500 ) -i set Tread to 12 ;DRAM voltage 2.08 ( i was afraid to put 2.1 because in my bios is with pink colour then it becomes red -sort of redline like the car`s rpm) MCH core ( 1.25-1.28 ) .....Skews i went to 150ps ( tested 50-100-150 on both CPU and RAM settings ) ........it boots hard at 470 but after that - nothing- tryed for fun 500 and it doesnt boot , though it takes a lot longer ( some improvement i think , maybe something minor i missed?)
    Right now im at my old backup ( 4.2 -9.5x450) which goes ok ( maybe i cant reach 500 , FSB gap or somthin? if so 450 will do , though a bit sad seeing others 500x8 , and i was wondering what to do to optimise RAM )
    Cooling problem i dont have , i have a 120mm fan that runs at full speed all the time; i have stable 38 celsius at idle and at full load around 60 on orthos and 65-68 on IBT (high) .......
