Hi, I have Intel Pentium 4 HT 524 (3.06) wich i am currently overcloking upto 3.68 Ghz with a core 2 duo fan installed, system is running nicely and the heatsink is warm not hot, i cant get the temeperature in windows. any ways i want to buy a dual core processor and intel has a dual core series of 1.6 and 1.8 which have same cores as core 2 duo and 65nm. so would 1.8ghz be better then my current cpu or not ?

my system specs are i have P4 Ht 524 3.06Ghz at 533 FSB motherboard is Asus P5B Wifi/Ap 946Gz Ram 1GB TwinMoss 577 bus Power Supply 430 Watts (CoolerMaster) my mother board has overclocking profiles when i overclock it to 20% its stable but when i overclock it to 30% it restarts on windows screen so should i stop overclockin it at 20% or try it at 30% with a water cooling? is it worth the effort ????

You don't need watercooling, you need to learn to overclock the right way. That means manually configuring the BIOS settings, not using some dumba$$ preconfigured profiles.

manually its complicated. but ill try

there are four options when i manually try, they are :- 1 CPU Frequency which can be adjustable from 133 to 400 2 Memory Frequency which cannot be adjusted only "auto" and "DDR-577" comes so i have it on auto 3 PCI-E Frequency which can be set from 90 to 150 but i have it on auto as well because no card is installed at the moment. 4 V-Core lots of temperature upto i guess 1.5 something but i have it on 1.4000 i have only changed 133 to 166 which takes my cpu to 3.81 GHz and it is stable at this position. i havent try 167 or 168 i jumped to 200 and problems started from word go the system wont give display and restarts so i gave more vcore about 1.415 but same result and when the system comes back it says overclocking failed or overvaultage failed. is this mean that i cant go further than this or do i have to do something else.. i opened CPU Z it showed that FSB:DRAM is 1:2 how can it be changed from bios or is this ok...

There is no "DDR-577"...do you mean DDR2-667? And while we're at it, is your board an "ASUS P5B Deluxe/WiFi-AP" rather than an "Asus P5B Wifi/Ap 946Gz"? And could the "946Gz" actually be the "P965" chipset? The CPU:DRAM ratio should be 1:1, not 1:2. In other words, if the CPU freq is 166MHz, the RAM freq should also be 166MHz (DDR2-333). AI tuning should be set to manual. The PCI-e freq should be locked in at 100MHz. PCI clock should be locked at 33.33MHz. Spread Spectrum should ALWAYS be disabled. RAM timings can be adjusted once you settle in on a RAM freq.

yeah sorry its not 577 its DDR2-533, and the board is Asus P5B-MX/Wifi-AP 946Gz. i now tried 168 and system is fine, ran games too, but i cant find the ratio of FSB:DRAM
