revisiting the barton xp chip

[Shingi]

I have current the follow items.

nf-7s version 2
xp2400+ mobile
hyperx pc2700 mem.

trying to oc this baby as high as i can. running on swiftec 462a heatsink and 3500rpm generic brand fan.

whenever i started bumping my voltage past 1.7 volts, the comp seems very unstable.
i was pusing 225x10 at 1.7 volts and did a normal sandra cpu benchmark and my computer just shuts down like 6 seconds or 5 seconds after test. and it beeps like this..

trying to best describe the sound. beep bop beep bop beep bop.
What does that sound mean?

ps problems?
i have a hipro 400watt ps. my voltage DOES NOT vary by more than 5 percent?
what could be?
only thing i can think of is my mosfets.

my cpu voltage fluntuates from 1.68 to 1.7 or 1.65 to 1.7.
i have a zalman northbridge cooler on. so no problem there.
my dimms are running 225 at 2.2.2.5 and test with memtest using test 5 looped 10 times.

oh yeah whenever i run prime it either shuts down and beep or the program freezes right away?


wat is causing this i can't bump my voltage higher if i do, i shut down problems?
anyone have this beeping problem when they up the voltage?

Did you try ur max without overvolt first? Also try to run dimms at 3-3-3-7 or even more relaxed

 

[Shingi]

yes i have tried my max without overvolt. and someone how my dimms did not like anything slower than cas 2.5. i have tried slowing down my timings to 2.5.3.3.7 and it still does the same shut down problems.

Maybe your processor just can't go any higher.
