If that is so I would consider increasing the CPU Voltage (vcore) more than what it is currently set at. As Taeric has said 1.7v is the recommended maximum value for the CPU voltage, still if your CPU is going to remain cool (55C or lower) then I would not worry that much about going a bit over that value.
Also make sure that your memory is still running at or below its rated speed or else this could cause stablability issues with the system. You can of course overclock your memory but make sure that it is operating correctly (standard test is to run memtest86 on it).

If you are convinced that it is actually not your CPU that is hindering you I would look in other places, logically I would look to the memory first, if that is not the problem check the PSU, then the next one I would check would be the motherboard (this is presuming all correct settings are implemented in the BIOS).
Something that you could try (relating to the motherboard) is to increase the motherboard voltage one notch to improve data transfer efficiency and this may allow you to hit higher speeds on your processor

Also something that may help to a degree would be to burn in your processor at the highest stable speed you can get, then in the future it may go even higher.
ok i will try this next. im almost to the point of just buying a 3.0 prescott and calling it a day with 3.5.

the psu is good... its brand new, antec 430w. the memory should have no problems, as its rated WAY higher then my cpu can take advantage of... ddr500.

now with the cpu voltage, its not staying at 1.7 its kinda fluctuating. it goes from like 1.68 to 1.71 then up and down depending on load. ill give it another shot here in a few minutes, ive got to install a dvd burner for my dad now though.

Minor vcore fluctuations aren't too much of a problem, and you will definitely notice some on your board (there's a well documented vcore droop under load with that and some other Asus boards). I have the same mobo and have noticed the droop, but it hasn't hindered my overclocking at all. Good luck.

Just one caution, try using two or three different programs to monitor temperatures since you're load temps appear to be excellently low. I would hate to see you fry something because one utility happens to be reading a temperature sensor incorrectly. If two or three programs read temps very close to each other, you're likely in very good shape.

i do use three. i use the asus program that came with the motherboard, i use speed fan 4 and i use MBM. all the same. bios says the same as well.

ok, so after a while of installing new video card, another hard drive, and some other stuff(still cant get my sound card working) i upped the voltage to 1.675(it reads 1.744 and fluctuates between 1.71 at idle, locks dead at 1.71 under load) and finally got the temps to go up a bit... 24c idle, and i dont know what load yet as im running a 3d mark 2001 se test right now. currently at 143 fsb after that voltage increase. im going to keep going until i cant post. after that ill back it down and run prime 95 all night and see where that gets me.

this is crap, i just got the computer to boot under 3.0 ghz!!!!! however, when i deleted the MSN file and messanger file, freaking windows wont load now. i HATE msn messanger and how it pops up at random times, i absolutely HATE IT. oh well, guess ill have to fix it tomorrow. DAMNIT i FINALLY GOT 3.0 TO LOAD AND THIS CRAP HAPPENS. UGH.

Baby steps, grasshopper. You got a boot at 50% OC; that's nothing to laugh at. You just have a few stability issues to work out before you move on to the next step. Be patient, and try not to get too frustrated. You're doing some really nice work.

well, i bought the 3.0 prescott today and its installed now, so far ive got it to 3.82 and ive had it to 3.87 still working some bugs out. im hoping for 4.0 my temps are decent, 43c under full load, 36@ idle. not terrible. going to see what else i can tweek. ill post some screen shots so you guys can give me some insight.
