with a stock cpu cooler, you wont get very far, i wouldnt try overclocking with one, unless you had a nice aftermarket HSF, but if you dont, dont buy one, for $92 with free shipping, you can get a core 2 based allendale cpu @ 2.4GHZ, it will destroy your pentium D, even overclocked VERY high, get it here

you can try with the stock cooler. the main thing to watch is the cpu temp. i believe the max rated for that chip is around 68C. you can download any number of programs to do this. hwmonitor and speedfan are two favorites. they are easily found with google.

The main problem I see here is the NB chipset. The 945G will not overclock at all. I suggest you get a new motherboard. Something like the Gigabyte P35-DS3L would allow you to get the 925 D to nearly 3.8 Ghz.

i o.c. that cpu to a max 4.2ghz stable
benchmarks results are almost equal to c2d 6600
but use to much energy

could be, but i would try the current board first just for fun. never know, you might get lucky. also, you gain valuable experience using something you might be expecting to replace anyway. always a plus, especially if you break something

Oh of course. What kind of being would we be if we allowed a motherboard to go untested? By all means push it!

Hi Bud

Myparents have a Pd 805 @ stock its 2660Mhz.
They have the same mother board as me because we built both pc together at the same time

They use a asus strike cooper pipe coolerbecause my old man likes to play flightsim and *****. This weekend i managed to get 3.2+ ghz out of it and PC mark 5 score of 85** this was with a 7600GT only slighty overclocked but i didn't do a prime test so i don't know how stable it is but my old don't care he just loves play that flipping game
